-### Describe Your Changes
-
-Please provide a brief description of the changes you made. Be as specific as possible to help others understand the purpose and impact of your modifications.
-
-### Checklist
-
-The following checks are mandatory:
-
-- [ ] I have read the [Contributing Guidelines](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/CONTRIBUTING.md)
-- [ ] All commits are signed and include `Signed-off-by` line. Use `git commit -s` to include `Signed-off-by` your commits. See this [doc](https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work) about how to sign your commits.

-- [ ] Linting is passing locally. Use `make check-all` to run all linters locally.
-
-Further checks are optional for External Contributions:
-
-- [ ] Include a link to the GitHub issue in the commit message, if issue exists.
-- [ ] Mention the change in the [Changelog](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/CHANGELOG.md). Explain what has changed and why. If there is a related issue or documentation change - link them as well.
-
-  Tips for writing a good changelog message::
-
-    * Write a human-readable changelog message that describes the problem and solution.
-    * Include a link to the issue or pull request in your changelog message.
-    * Use specific language identifying the fix, such as an error message, metric name, or flag name.
-    * Provide a link to the relevant documentation for any new features you add or modify.
-
-- [ ] After your pull request is merged, please add a message to the issue with instructions for how to test the fix or try the feature you added. Here is an [example](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4048#issuecomment-1546453726)
-- [ ] Do not close the original issue before the change is released. Please note, in some cases Github can automatically close the issue once PR is merged. Re-open the issue in such case.
-- [ ] If the change somehow affects public interfaces (a new flag was added or updated, or some behavior has changed) - add the corresponding change to documentation.
-
-
-Examples of good changelog messages:
-
-1. FEATURE: [vmagent](https://docs.victoriametrics.com/vmagent.html): add support for [VictoriaMetrics remote write protocol](https://docs.victoriametrics.com/vmagent.html#victoriametrics-remote-write-protocol) when [sending / receiving data to / from Kafka](https://docs.victoriametrics.com/vmagent.html#kafka-integration). This protocol allows saving egress network bandwidth costs when sending data from `vmagent` to `Kafka` located in another datacenter or availability zone. See [this feature request](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1225).
-
-2. BUGFIX: [stream aggregation](https://docs.victoriametrics.com/stream-aggregation.html): suppress `series after dedup` error message in logs when `-remoteWrite.streamAggr.dedupInterval` command-line flag is set at [vmagent](https://docs.victoriametrics.com/vmgent.html) or when `-streamAggr.dedupInterval` command-line flag is set at [single-node VictoriaMetrics](https://docs.victoriametrics.com/).

+## vmagent
 
-vmagent docs can be edited at [docs/vmagent.md](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/vmagent.md).
+`vmagent` is a tiny but brave agent, which helps you collect metrics from various sources
+and stores them in [VictoriaMetrics](https://github.com/VictoriaMetrics/VictoriaMetrics)
+or any other Prometheus-compatible storage system that supports the `remote_write` protocol.
+
+<img alt="vmagent" src="vmagent.png">
+
+
+## Motivation
+
+While VictoriaMetrics provides an efficient solution to store and observe metrics, our users needed something fast
+and RAM friendly to scrape metrics from Prometheus-compatible exporters to VictoriaMetrics.
+Also, we found that users’ infrastructure are snowflakes - no two are alike, and we decided to add more flexibility
+to `vmagent` (like the ability to push metrics instead of pulling them). We did our best and plan to do even more.
+
+
+## Features
+
+* Can be used as drop-in replacement for Prometheus for scraping targets such as [node_exporter](https://github.com/prometheus/node_exporter).
+  See [Quick Start](#quick-start) for details.
+* Can add, remove and modify labels (aka tags) via Prometheus relabeling. Can filter data before sending it to remote storage. See [these docs](#relabeling) for details.
+* Accepts data via all the ingestion protocols supported by VictoriaMetrics:
+  * Influx line protocol via `http://<vmagent>:8429/write`. See [these docs](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-send-data-from-influxdb-compatible-agents-such-as-telegraf).
+  * Graphite plaintext protocol if `-graphiteListenAddr` command-line flag is set. See [these docs](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-send-data-from-graphite-compatible-agents-such-as-statsd).
+  * OpenTSDB telnet and http protocols if `-opentsdbListenAddr` command-line flag is set. See [these docs](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-send-data-from-opentsdb-compatible-agents).
+  * Prometheus remote write protocol via `http://<vmagent>:8429/api/v1/write`.
+  * JSON lines import protocol via `http://<vmagent>:8429/api/v1/import`. See [these docs](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-import-data-in-json-line-format).
+  * Native data import protocol via `http://<vmagent>:8429/api/v1/import/native`. See [these docs](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-import-data-in-native-format).
+  * Data in Prometheus exposition format. See [these docs](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-import-data-in-prometheus-exposition-format) for details.
+  * Arbitrary CSV data via `http://<vmagent>:8429/api/v1/import/csv`. See [these docs](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-import-csv-data).
+* Can replicate collected metrics simultaneously to multiple remote storage systems.
+* Works in environments with unstable connections to remote storage. If the remote storage is unavailable, the collected metrics
+  are buffered at `-remoteWrite.tmpDataPath`. The buffered metrics are sent to remote storage as soon as connection
+  to remote storage is recovered. The maximum disk usage for the buffer can be limited with `-remoteWrite.maxDiskUsagePerURL`.
+* Uses lower amounts of RAM, CPU, disk IO and network bandwidth compared to Prometheus.
+
+
+## Quick Start
+
+Just download `vmutils-*` archive from [releases page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases), unpack it
+and pass the following flags to `vmagent` binary in order to start scraping Prometheus targets:
+
+* `-promscrape.config` with the path to Prometheus config file (it is usually located at `/etc/prometheus/prometheus.yml`)
+* `-remoteWrite.url` with the remote storage endpoint such as VictoriaMetrics. The `-remoteWrite.url` argument can be specified multiple times in order to replicate data concurrently to an arbitrary number of remote storage systems.
+
+Example command line:
+
+```
+/path/to/vmagent -promscrape.config=/path/to/prometheus.yml -remoteWrite.url=https://victoria-metrics-host:8428/api/v1/write
+```
+
+If you only need to collect Influx data, then the following is sufficient:
+
+```
+/path/to/vmagent -remoteWrite.url=https://victoria-metrics-host:8428/api/v1/write
+```
+
+Then send Influx data to `http://vmagent-host:8429`. See [these docs](https://victoriametrics.github.io/Single-server-VictoriaMetrics.html#how-to-send-data-from-influxdb-compatible-agents-such-as-telegraf) for more details.
+
+`vmagent` is also available in [docker images](https://hub.docker.com/r/victoriametrics/vmagent/tags).
+
+Pass `-help` to `vmagent` in order to see the full list of supported command-line flags with their descriptions.
+
+
+## Configuration update
+
+`vmagent` should be restarted in order to update config options set via command-line args.
+
+`vmagent` supports multiple approaches for reloading configs from updated config files such as `-promscrape.config`, `-remoteWrite.relabelConfig` and `-remoteWrite.urlRelabelConfig`:
+
+* Sending `SUGHUP` signal to `vmagent` process:
+  ```bash
+  kill -SIGHUP `pidof vmagent`
+  ```
+
+* Sending HTTP request to `http://vmagent:8429/-/reload` endpoint.
+
+There is also `-promscrape.configCheckInterval` command-line option, which can be used for automatic reloading configs from updated `-promscrape.config` file.
+
+
+## Use cases
+
+
+### IoT and Edge monitoring
+
+`vmagent` can run and collect metrics in IoT and industrial networks with unreliable or scheduled connections to the remote storage.
+It buffers the collected data in local files until the connection to remote storage becomes available and then sends the buffered
+data to the remote storage. It re-tries sending the data to remote storage on any errors.
+The maximum buffer size can be limited with `-remoteWrite.maxDiskUsagePerURL`.
+
+`vmagent` works on various architectures from IoT world - 32-bit arm, 64-bit arm, ppc64, 386, amd64.
+See [the corresponding Makefile rules](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/app/vmagent/Makefile) for details.
+
+
+### Drop-in replacement for Prometheus
+
+If you use Prometheus only for scraping metrics from various targets and forwarding these metrics to remote storage,
+then `vmagent` can replace such Prometheus setup. Usually `vmagent` requires lower amounts of RAM, CPU and network bandwidth comparing to Prometheus for such a setup.
+See [these docs](#how-to-collect-metrics-in-prometheus-format) for details.
+
+
+### Replication and high availability
+
+`vmagent` replicates the collected metrics among multiple remote storage instances configured via `-remoteWrite.url` args.
+If a single remote storage instance temporarily is out of service, then the collected data remains available in another remote storage instances.
+`vmagent` buffers the collected data in files at `-remoteWrite.tmpDataPath` until the remote storage becomes available again.
+Then it sends the buffered data to the remote storage in order to prevent data gaps in the remote storage.
+
+
+### Relabeling and filtering
+
+`vmagent` can add, remove or update labels on the collected data before sending it to remote storage. Additionally,
+it can remove unwanted samples via Prometheus-like relabeling before sending the collected data to remote storage.
+See [these docs](#relabeling) for details.
+
+
+### Splitting data streams among multiple systems
+
+`vmagent` supports splitting the collected data between muliple destinations with the help of `-remoteWrite.urlRelabelConfig`,
+which is applied independently for each configured `-remoteWrite.url` destination. For instance, it is possible to replicate or split
+data among long-term remote storage, short-term remote storage and real-time analytical system [built on top of Kafka](https://github.com/Telefonica/prometheus-kafka-adapter).
+Note that each destination can receive its own subset of the collected data thanks to per-destination relabeling via `-remoteWrite.urlRelabelConfig`.
+
+
+### Prometheus remote_write proxy
+
+`vmagent` may be used as a proxy for Prometheus data sent via Prometheus `remote_write` protocol. It can accept data via `remote_write` API
+at `/api/v1/write` endpoint, apply relabeling and filtering and then proxy it to another `remote_write` systems.
+The `vmagent` can be configured to encrypt the incoming `remote_write` requests with `-tls*` command-line flags.
+Additionally, Basic Auth can be enabled for the incoming `remote_write` requests with `-httpAuth.*` command-line flags.
+
+
+### remote_write for clustered version
+
+Despite `vmagent` can accept data in several supported protocols (OpenTSDB, Influx, Prometheus, Graphite) and scrape data from various targets, writes always peformed in Promethes remote_write protocol. Therefore for clustered version `-remoteWrite.url` command-line flag should be configured as `<schema>://<vminsert-host>:8480/insert/<customer-id>/prometheus/api/v1/write`
+
+
+## How to collect metrics in Prometheus format
+
+Pass the path to `prometheus.yml` to `-promscrape.config` command-line flag. `vmagent` takes into account the following
+sections from [Prometheus config file](https://prometheus.io/docs/prometheus/latest/configuration/configuration/):
+
+* `global`
+* `scrape_configs`
+
+All the other sections are ignored, including [remote_write](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#remote_write) section.
+Use `-remoteWrite.*` command-line flags instead for configuring remote write settings.
+
+The following scrape types in [scrape_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config) section are supported:
+
+* `static_configs` - for scraping statically defined targets. See [these docs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#static_config) for details.
+* `file_sd_configs` - for scraping targets defined in external files aka file-based service discover.
+  See [these docs](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#file_sd_config) for details.
+* `kubernetes_sd_configs` - for scraping targets in Kubernetes (k8s).
+  See [kubernetes_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#kubernetes_sd_config) for details.
+* `ec2_sd_configs` - for scraping targets in Amazon EC2.
+  See [ec2_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#ec2_sd_config) for details.
+  `vmagent` doesn't support `profile` config param and aws credentials file yet.
+* `gce_sd_configs` - for scraping targets in Google Compute Engine (GCE).
+  See [gce_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#gce_sd_config) for details.
+  `vmagent` provides the following additional functionality for `gce_sd_config`:
+  * if `project` arg is missing, then `vmagent` uses the project for the instance where it runs;
+  * if `zone` arg is missing, then `vmagent` uses the zone for the instance where it runs;
+  * if `zone` arg equals to `"*"`, then `vmagent` discovers all the zones for the given project;
+  * `zone` may contain arbitrary number of zones, i.e. `zone: [us-east1-a, us-east1-b]`.
+* `consul_sd_configs` - for scraping targets registered in Consul.
+  See [consul_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#consul_sd_config) for details.
+* `dns_sd_configs` - for scraping targets discovered from DNS records (SRV, A and AAAA).
+  See [dns_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#dns_sd_config) for details.
+* `openstack_sd_configs` - for scraping OpenStack targets.
+  See [openstack_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#openstack_sd_config) for details.
+  [OpenStack identity API v3](https://docs.openstack.org/api-ref/identity/v3/) is supported only.
+* `dockerswarm_sd_configs` - for scraping Docker Swarm targets.
+  See [dockerswarm_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#dockerswarm_sd_config) for details.
+* `eureka_sd_configs` - for scraping targets registered in [Netflix Eureka](https://github.com/Netflix/eureka).
+  See [eureka_sd_config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#eureka_sd_config) for details.
+
+File feature requests at [our issue tracker](https://github.com/VictoriaMetrics/VictoriaMetrics/issues) if you need other service discovery mechanisms to be supported by `vmagent`.
+
+`vmagent` also support the following additional options in `scrape_config` section:
+
+* `disable_compression: true` - for disabling response compression on a per-job basis. By default `vmagent` requests compressed responses from scrape targets
+  in order to save network bandwidth.
+* `disable_keepalive: true` - for disabling [HTTP keep-alive connections](https://en.wikipedia.org/wiki/HTTP_persistent_connection) on a per-job basis.
+  By default `vmagent` uses keep-alive connections to scrape targets in order to reduce overhead on connection re-establishing.
+
+Note that `vmagent` doesn't support `refresh_interval` option these scrape configs. Use the corresponding `-promscrape.*CheckInterval`
+command-line flag instead. For example, `-promscrape.consulSDCheckInterval=60s` sets `refresh_interval` for all the `consul_sd_configs`
+entries to 60s. Run `vmagent -help` in order to see default values for `-promscrape.*CheckInterval` flags.
+
+The file pointed by `-promscrape.config` may contain `%{ENV_VAR}` placeholders, which are substituted by the corresponding `ENV_VAR` environment variable values.
+
+
+## Adding labels to metrics
+
+Labels can be added to metrics via the following mechanisms:
+
+* Via `global -> external_labels` section in `-promscrape.config` file. These labels are added only to metrics scraped from targets configured in `-promscrape.config` file.
+* Via `-remoteWrite.label` command-line flag. These labels are added to all the collected metrics before sending them to `-remoteWrite.url`.
+
+
+## Relabeling
+
+`vmagent` supports [Prometheus relabeling](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#relabel_config).
+Additionally it provides the following extra actions:
+
+* `replace_all`: replaces all the occurences of `regex` in the values of `source_labels` with the `replacement` and stores the result in the `target_label`.
+* `labelmap_all`: replaces all the occurences of `regex` in all the label names with the `replacement`.
+* `keep_if_equal`: keeps the entry if all label values from `source_labels` are equal.
+* `drop_if_equal`: drops the entry if all the label values from `source_labels` are equal.
+
+The relabeling can be defined in the following places:
+
+* At `scrape_config -> relabel_configs` section in `-promscrape.config` file. This relabeling is applied to target labels.
+* At `scrape_config -> metric_relabel_configs` section in `-promscrape.config` file. This relabeling is applied to all the scraped metrics in the given `scrape_config`.
+* At `-remoteWrite.relabelConfig` file. This relabeling is aplied to all the collected metrics before sending them to remote storage.
+* At `-remoteWrite.urlRelabelConfig` files. This relabeling is applied to metrics before sending them to the corresponding `-remoteWrite.url`.
+

+
+
+## Monitoring
+
+`vmagent` exports various metrics in Prometheus exposition format at `http://vmagent-host:8429/metrics` page. It is recommended setting up regular scraping of this page
+either via `vmagent` itself or via Prometheus, so the exported metrics could be analyzed later.
+Use official [Grafana dashboard](https://grafana.com/grafana/dashboards/12683) for `vmagent` state overview.
+If you have suggestions, improvements or found a bug - feel free to open an issue on github or add review to the dashboard.
+
+`vmagent` also exports target statuses at the following handlers:
+
+* `http://vmagent-host:8429/targets`. This handler returns human-readable plaintext status for every active target.
+This page is convenient to query from command line with `wget`, `curl` or similar tools.
+It accepts optional `show_original_labels=1` query arg, which shows the original labels per each target before applying relabeling.
+This information may be useful for debugging target relabeling.
+* `http://vmagent-host:8429/api/v1/targets`. This handler returns data compatible with [the corresponding page from Prometheus API](https://prometheus.io/docs/prometheus/latest/querying/api/#targets).
+
+* `http://vmagent-host:8429/ready`. This handler returns http 200 status code when `vmagent` finishes initialization for all service_discovery configs.
+It may be useful for performing `vmagent` rolling update without scrape loss.
+
+
+## Troubleshooting
+
+* It is recommended [setting up the official Grafana dashboard](#monitoring) in order to monitor `vmagent` state.
+
+* It is recommended increasing the maximum number of open files in the system (`ulimit -n`) when scraping big number of targets,
+  since `vmagent` establishes at least a single TCP connection per each target.
+
+* When `vmagent` scrapes many unreliable targets, it can flood error log with scrape errors. These errors can be suppressed
+  by passing `-promscrape.suppressScrapeErrors` command-line flag to `vmagent`. The most recent scrape error per each target can be observed at `http://vmagent-host:8429/targets`
+  and `http://vmagent-host:8429/api/v1/targets`.
+
+* The `/api/v1/targets` page could be useful for debugging relabeling process for scrape targets.
+  This page contains original labels for targets dropped during relabeling (see "droppedTargets" section in the page output). By default up to `-promscrape.maxDroppedTargets` targets are shown here. If your setup drops more targets during relabeling, then increase `-promscrape.maxDroppedTargets` command-line flag value in order to see all the dropped targets. Note that tracking each dropped target requires up to 10Kb of RAM, so big values for `-promscrape.maxDroppedTargets` may result in increased memory usage if big number of scrape targets are dropped during relabeling.
+
+* If `vmagent` scrapes big number of targets, then `-promscrape.dropOriginalLabels` command-line option may be passed to `vmagent` in order to reduce memory usage.
+  This option drops `"discoveredLabels"` and `"droppedTargets"` lists at `/api/v1/targets` page, which may result in reduced debuggability for improperly configured per-target relabeling.
+
+* If `vmagent` scrapes targets with millions of metrics per each target (for instance, when scraping [federation endpoints](https://prometheus.io/docs/prometheus/latest/federation/)),
+  then it is recommended enabling `stream parsing mode` in order to reduce memory usage during scraping. This mode may be enabled either globally for all the scrape targets
+  by passing `-promscrape.streamParse` command-line flag or on a per-scrape target basis with `stream_parse: true` option. For example:
+
+  ```yml
+  scrape_configs:
+  - job_name: 'big-federate'
+    stream_parse: true
+    static_configs:
+    - targets:
+      - big-prometeus1
+      - big-prometeus2
+    honor_labels: true
+    metrics_path: /federate
+    params:
+      'match[]': ['{__name__!=""}']
+  ```
+
+  Note that `sample_limit` option doesn't work if stream parsing is enabled, since the parsed data is pushed to remote storage as soon as it is parsed. So `sample_limit` option
+  has no sense during stream parsing.
+
+* It is recommended to increase `-remoteWrite.queues` if `vmagent_remotewrite_pending_data_bytes` metric exported at `http://vmagent-host:8429/metrics` page constantly grows.
+
+* If you see gaps on the data pushed by `vmagent` to remote storage when `-remoteWrite.maxDiskUsagePerURL` is set, then try increasing `-remoteWrite.queues`.
+  Such gaps may appear because `vmagent` cannot keep up with sending the collected data to remote storage, so it starts dropping the buffered data
+  if the on-disk buffer size exceeds `-remoteWrite.maxDiskUsagePerURL`.
+
+* `vmagent` buffers scraped data at `-remoteWrite.tmpDataPath` directory until it is sent to `-remoteWrite.url`.
+  The directory can grow large when remote storage is unavailable for extended periods of time and if `-remoteWrite.maxDiskUsagePerURL` isn't set.
+  If you don't want to send all the data from the directory to remote storage, simply stop `vmagent` and delete the directory.
+
+* By default `vmagent` masks `-remoteWrite.url` with `secret-url` values in logs and at `/metrics` page because
+  the url may contain sensitive information such as auth tokens or passwords.
+  Pass `-remoteWrite.showURL` command-line flag when starting `vmagent` in order to see all the valid urls.
+
+* If you see `skipping duplicate scrape target with identical labels` errors when scraping Kubernetes pods, then it is likely these pods listen multiple ports
+  or they use init container. These errors can be either fixed or suppressed with `-promscrape.suppressDuplicateScrapeTargetErrors` command-line flag.
+  See available options below if you prefer fixing the root cause of the error:
+
+  The following `relabel_configs` section may help determining `__meta_*` labels resulting in duplicate targets:
+  ```yml
+  - action: labelmap
+    regex: __meta_(.*)
+  ```
+
+  The following relabeling rule may be added to `relabel_configs` section in order to filter out pods with unneeded ports:
+  ```yml
+  - action: keep_if_equal
+    source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_port, __meta_kubernetes_pod_container_port_number]
+  ```
+
+  The following relabeling rule may be added to `relabel_configs` section in order to filter out init container pods:
+  ```yml
+  - action: drop
+    source_labels: [__meta_kubernetes_pod_container_init]
+    regex: true
+  ```
+
+
+## How to build from sources
+
+It is recommended using [binary releases](https://github.com/VictoriaMetrics/VictoriaMetrics/releases) - `vmagent` is located in `vmutils-*` archives there.
+
+
+### Development build
+
+1. [Install Go](https://golang.org/doc/install). The minimum supported version is Go 1.13.
+2. Run `make vmagent` from the root folder of the repository.
+   It builds `vmagent` binary and puts it into the `bin` folder.
+
+### Production build
+
+1. [Install docker](https://docs.docker.com/install/).
+2. Run `make vmagent-prod` from the root folder of the repository.
+   It builds `vmagent-prod` binary and puts it into the `bin` folder.
+
+### Building docker images
+
+Run `make package-vmagent`. It builds `victoriametrics/vmagent:<PKG_TAG>` docker image locally.
+`<PKG_TAG>` is auto-generated image tag, which depends on source code in the repository.
+The `<PKG_TAG>` may be manually set via `PKG_TAG=foobar make package-vmagent`.
+
+The base docker image is [alpine](https://hub.docker.com/_/alpine) but it is possible to use any other base image
+by setting it via `<ROOT_IMAGE>` environment variable. For example, the following command builds the image on top of [scratch](https://hub.docker.com/_/scratch) image:
+
+```bash
+ROOT_IMAGE=scratch make package-vmagent
+```
+
+### ARM build
+
+ARM build may run on Raspberry Pi or on [energy-efficient ARM servers](https://blog.cloudflare.com/arm-takes-wing/).
+
+### Development ARM build
+
+1. [Install Go](https://golang.org/doc/install). The minimum supported version is Go 1.13.
+2. Run `make vmagent-arm` or `make vmagent-arm64` from the root folder of the repository.
+   It builds `vmagent-arm` or `vmagent-arm64` binary respectively and puts it into the `bin` folder.
+
+### Production ARM build
+
+1. [Install docker](https://docs.docker.com/install/).
+2. Run `make vmagent-arm-prod` or `make vmagent-arm64-prod` from the root folder of the repository.
+   It builds `vmagent-arm-prod` or `vmagent-arm64-prod` binary respectively and puts it into the `bin` folder.
+
+
+## Profiling
+
+`vmagent` provides handlers for collecting the following [Go profiles](https://blog.golang.org/profiling-go-programs):
+
+* Memory profile. It can be collected with the following command:

+
+See the docs at https://victoriametrics.github.io/vmagent.html .
+
+  -csvTrimTimestamp duration
+    	Trim timestamps when importing csv data to this duration. Minimum practical duration is 1ms. Higher duration (i.e. 1s) may be used for reducing disk space usage for timestamp data (default 1ms)
+  -dryRun
+    	Whether to check only config files without running vmagent. The following files are checked: -promscrape.config, -remoteWrite.relabelConfig, -remoteWrite.urlRelabelConfig . Unknown config entries are allowed in -promscrape.config by default. This can be changed with -promscrape.config.strictParse
+  -enableTCP6
+    	Whether to enable IPv6 for listening and dialing. By default only IPv4 TCP is used
+  -envflag.enable
+    	Whether to enable reading flags from environment variables additionally to command line. Command line flag values have priority over values from environment vars. Flags are read only from command line if this flag isn't set
+  -envflag.prefix string
+    	Prefix for environment variables if -envflag.enable is set
+  -fs.disableMmap
+    	Whether to use pread() instead of mmap() for reading data files. By default mmap() is used for 64-bit arches and pread() is used for 32-bit arches, since they cannot read data files bigger than 2^32 bytes in memory. mmap() is usually faster for reading small data chunks than pread()
+  -graphiteListenAddr string
+    	TCP and UDP address to listen for Graphite plaintext data. Usually :2003 must be set. Doesn't work if empty

+  -httpAuth.username string
+    	Username for HTTP Basic Auth. The authentication is disabled if empty. See also -httpAuth.password
+  -httpListenAddr string
+    	TCP address to listen for http connections. Set this flag to empty value in order to disable listening on any port. This mode may be useful for running multiple vmagent instances on the same server. Note that /targets and /metrics pages aren't available if -httpListenAddr='' (default ":8429")
+  -import.maxLineLen max_rows_per_line
+    	The maximum length in bytes of a single line accepted by /api/v1/import; the line length can be limited with max_rows_per_line query arg passed to /api/v1/export
