http.Request was used as a part of state struct
for generating the curl command when viewing the rule's
state changes.
It appears, that holding a referencing is far more expensive
than generating the curl command immediately.
On the test with 40k rules, this change reduces memory
and CPU usage by 50%.

The main purpose of this command-line flag is to increase the lifetime of low-end flash storage
with the limited number of write operations it can perform. Such flash storage is usually
installed on Raspberry PI or similar appliances.
For example, `-inmemoryDataFlushInterval=1h` reduces the frequency of disk write operations
to up to once per hour if the ingested one-hour worth of data fits the limit for in-memory data.
The in-memory data is searchable in the same way as the data stored on disk.
VictoriaMetrics automatically flushes the in-memory data to disk on graceful shutdown via SIGINT signal.
The in-memory data is lost on unclean shutdown (hardware power loss, OOM crash, SIGKILL).

The purpose of the update is to make the dash more usable
for large installations with many instances. Panels which showed
metrics per-instance (Mem, CPU) now are showing metrics per-job or min/max/avg
aggregations in % instead. This supposed to help immediately to identify
resource shortage and remain usable for small and big installations.
For cases when detailed info is needed, to the bottom of the dashboard
a new row `Drilldown` was added. Panels like Mem or CPU now contain
a `data-link` named `Drilldown` (cis shown on line click) which takes
user to more detailed panel.

It has been appeared that some production workloads could suffer for some time
after every reset of the previous cache when it gets less than 5% of requests
after the needed item isn't found in the current cache. This could result
in reduced cache hit rates, which, in turn, could increase CPU, disk IO and RAM
usage needed for reading, unpacking and caching the missed data from disk.
This commit reduces the cache miss threshold for resetting the previous cache from 5% to 1%.
This should reduce the possible negative impact after each cache reset by at least 5x,
while reducing the total memory used by caches.

The issue was in the `labels := dst[offset:]` line in the beginning of appendExtraLabels() function.
The `dst` may be re-allocated when adding extra labels to it. In this case the addition of `exported_`
prefix to labels inside `labels` slice become invisible in the returned `dst` labels.
While at it, properly handle some corner cases:
- Add additional `exported_` prefix to clashing metric labels with already existing `exported_` prefix.
- Store scraped metric names in `exported___name__` label if scrape target contains `__name__` label.

Previously the `quotesEscape` function was escaping only double quotes.
This wasn't enough, since the input string could contain other special chars,
which must be escaped when put inside JSON string. For example, carriage return and line feed chars (\n\r),
backslash char, etc. This led to the following issues, which were improperly fixed:
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/890 - this issue
was "fixed" by introducing the `crlfEscape` function, which led to unnecessary
complications in user templates, while not fixing various corner cases
such as backslash chars in the input string.
See 1de15ad490
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 - this issue
was "fixed" by urlencoding the whole string passed to -external.alert.source
command-line flag. This led to invalid urls, which couldn't be parsed by Grafana.
See 00c838353d
and 4bd0244599
This commit properly encodes the input string passed to `quotesEscape`, so it can be safely embedded inside JSON strings.
This commit deprecates crlfEscape template function and adds the following new template functions:
- strvalue and stripDomain - these functions are supported by Prometheus, so they were added
for compatibility purposes.
- jsonEscape and htmlEscape for converting the input string to valid quoted JSON string
and for html-escaping the input string, so it could be safely embedded as a plaintext
into html.
This commit also documents all supported template functions at https://docs.victoriametrics.com/vmalert.html#template-functions
The deprecated crlfEscape function isn't documented on purpose, since its usefulness is negative in general case.
This reverts commit 00c838353d.
Reason for revert: it incorrectly fixes the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 .
Now `-external.alert.source=explore?orgId=1&left=...` is converted to the following invalid url, which cannot be handled by Grafana:
https://grafana.example.com/explore%3ForgId%3D1%26left%3D...
The next commit will contain the correct fix of the issue - the `quotesEscape` function must
properly escape the string, so it could be embedded into JSON string. This function must
properly escape \n\r chars too. In this case the `crlfEscape` function becomes unnecessary.
Actually, the next commit makes the `crlfEscape` function deprecated.
Previously netstorage.MustStop() call didn't free up all the resources,
so the subsequent call to nestorage.Init() would panic.
This allows writing tests, which call nestorage.Init() + nestorage.MustStop() in a loop.
Blocks outside the configured retention are eventually deleted during background merge.
But such blocks may reside in the storage for long time until background merge.
Previously VictoriaMetrics could spend additional CPU time on processing such blocks
during search queries. Now these blocks are skipped.
The searchTSIDs function was searching for metricIDs matching the the given tag filters
and then was locating the corresponding TSID entries for the found metricIDs.
The TSID entries aren't needed when searching for time series names (aka MetricName),
so this commit removes the uneeded TSID search from the implementation of /api/v1/series API.
This improves perfromance of /api/v1/series calls.
This commit also improves performance a bit for /api/v1/query and /api/v1/query_range calls,
since now these calls cache small metricIDs instead of big TSID entries
in the indexdb/tagFilters cache (now this cache is named indexdb/tagFiltersToMetricIDs)
without the need to compress the saved entries in order to save cache space.
This commit also removes concurrency limiter during searching for matching time series,
which was introduced in 8f16388428, since the concurrency
for all the read queries is already limited with -search.maxConcurrentRequests command-line flag.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/648
This increases the maximum time for cache population with new entries from 20 minutes to 40 minutes.
This
This change shouldn't increase memory usage for caches, since the prev cache cleaner
should free up memory by deleting unused prev cache as soon as possible.
See 08ca45d238 for details on prev cache cleaner.
The panic has been introduced in 68f3a02589
While at it, add padding to shard structs in order to avoid false sharing on mordern CPUs
This should improve scalability on systems with many CPU cores
This means that the majority of requests are successfully served from the current cache,
so the previous cache can be reset in order to free up memory.
The message about dropped data still remains at `error` level.
The change supposed to make log message more clear about how
serious it is.

Sort labels explicitly after calling the ParsedConfigs.Apply() when needed.
This reduces CPU usage when performing metric-level relabeling, where labels' sorting isn't needed.
Previously the `__address__` label could contain only `host:port` part of the target url,
while the scheme and metrics path were obtained from `__scheme__` and `__metrics_path__`
labels. Now it is possible to set the full url in `__address__` label.
This makes valid the following scrape config, which is frequently used by novice users:
scrape_configs:
- job_name: foo
static_configs:
- targets:
- http://host1/metrics1
- https://host2/metrics2

Cache `action: replace` results for non-trivial regexs and return them next time
instead of performing CPU-intensive regex replacement.
Optimize also `action: labelmap_all` and `action: replace_all` in the same way.
Previously empty series (e.g. series with all NaN samples) were passed to aggregate functions.
Such series must be ingored by all the aggregate functions.
So it is better from consistency PoV filtering out empty series before applying aggregate functions.
* app/vmselect: ignore empty series for `limit_offset`
VictoriaMetrics doesn't return empty series (with all NaN values) to
the user. But such series are filtered after transform functions.
It means `limit_offset` will account for empty series as well.
For example, let's consider following data set:
```
time series:
foo{label="1"} NaN, NaN, NaN, NaN // empty series
foo{label="2"} 1, 2, 3, 4
foo{label="3"} 4, 3, 2, 1
```
When user requests all series for metric `foo` the empty series
will be filtered out:
```
/query=foo:
foo{label="v2"} 1, 2, 3, 4
foo{label="v3"} 4, 3, 2, 1
```
But `limit_offset(1, 1, foo)` is applied to original series, not filtered yet.
So it will return `foo{label="v2"}` (skips the first in list)
```
/query=limit_offset(1, 1, foo):
foo{label="v2"} 1, 2, 3, 4
```
Expected result would be to apply `limit_offset` to already filtered list,
so in result we receive `foo{label="v3"}`:
```
/query=limit_offset(1, 1, foo):
foo{label="v3"} 4, 3, 2, 1
```
The change does exactly that - filters empty series before applying `limit_offset`.

* vmalert: always re-evaluate Annotations
Previously, Annotations were evaluated only:
1. On alert creating.
2. On alert's value change.
This is premature optimization. It was assumed that since annotations
could contain only text with alert's labels or value - there is no need
in spending resources to re-compile Annotations.
Later, template function `query` was added, which can execute
arbitrary queries and return different results on every evaluation.
So if it was used in annotations, it would be executed only on init
or value change.
Another case when optimization caused an issue - annotations hot reload.
In this case, annotations of the active alert won't change even if Rule's
annotations were changed.
This fix enables Annotations re-evaluation on each iteration to resolve
issues above. It would have some impact on performance, but it is unlikely
it will be noticeable.

Cache sanitized label names and return them next time.
This reduces the number of allocations and speeds up the SanitizeLabelName()

The following regex patterns are optimized:
- literal string match, e.g. "foo"
- prefix match, e.g. "foo.*" and "foo.+"
- substring match, e.g. ".*foo.*" and ".+foo.+"
- alternate values match, e.g. "foo|bar|baz"
This is OK, since the anchors are implicitly applied to the whole regexp.
This optimization should improve the speed for regexp series filters with explicit $ and ^ anchors.
For example, `{label="^(foo|bar)$"}`

Previously a single syncwg.WaitGroup was used for tracking the lifetime of processBlock callbacks
across all the per-vmstorage goroutines. This could be slow on systems with many CPU cores
because of inter-CPU synchronization overhead.
Use a separate per-vmstorage sync.WaitGroup instead in order to reduce inter-CPU synchronization overhead.
This should imrpove performance for heavy queries over big number of blocks on multi-CPU systems.
Other components, such as `vmagent`, mark these flags as sensitive and
hide them from the `/metrics` endpoint by default. This commit adds
similar handling to the `vmalert` component, hiding them by default, to
prevent logging of secrets inappropriately.

The change allows to specify default value for `getScrapeInterval`
function when actual interval can't be calculated.
Before the change, function were returning `maxSilenceInterval` (5m)
in such cases, which may be not correct for instant queries processing.
The specific scenario where using `maxSilenceInterval` caused issues
is the following:
1. Series becomes stale;
2. Client (in this case vmalert) continues to request series every 15s;
3. Database returns empty results as expected;
4. But at some specific moment of time database returns datapoints from `now()-5m`,
because lookback window was extended to `maxSilenceInterval`.

- show dates in human-readable format, e.g. 2022-05-07, instead of a numeric value
- limit the maximum length of queries and filters shown in trace messages
Production experience shows that 100k is too big for /api/v1/series .
It leads to increased CPU usage when Grafana queries /api/v1/series over VictoriaMetrics
with big number of time series during auto-completion and when modifying template variables.
Previously SearchMetricNames was returning unmarshaled metric names.
This wasn't great for vmstorage, which should spend additional CPU time
for marshaling the metric names before sending them to vmselect.
While at it, remove possible duplicate metric names, which could occur when
multiple samples for new time series are ingested via concurrent requests.
Also sort the metric names before returning them to the client.
This simplifies debugging of the returned metric names across repeated requests to /api/v1/series
querytracer has been added to the following storage.Storage methods:
- RegisterMetricNames
- DeleteMetrics
- SearchTagValueSuffixes
- SearchGraphitePaths
Previously the cache could store 10K unique regexps. When every regexp is huge (e.g. hundreds of kilobytes),
then the total cache size could grow to multiples of gigabytes. Now the cache size is limited by the total length
of all cached regexps. So huge regexps won't result in high memory usage for the cache.
alerts: filter out non error log messages for `TooManyLogs`
Info and Warn error levels aren't always a result of malfunctioning
or faulty state. So we filter them out.
If the previous dial attempt was unsuccessful, then all the new dial attempts are skipped
until the background goroutine determines that the given address can be successfully dialed.
This reduces query latency when some of vmstorage nodes are unavailable and dialing them is slow.
This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/711
This commit is based on ideas from the https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2756
The main differences are:
- The check for healthy/unhealthy storage nodes is moved one level lower from app/vmselect/netstorage to lib/netutil.ConnPool.
This makes possible re-using this feature everywhere lib/netutil.ConnPool is used.
- The check doesn't take into account handshake errors for already established connections.
Handshake errors usually mean improperly configured VictoriaMetrics cluster, so they shouldn't be ignored.
The commit 5fb45173ae takes into account only newly registered series
when applying cardinality limits. This means that the cardinality limit could be exceeded with already registered series.
This commit returns back accounting for already registered series when applying cardinality limits.
Previously the creation of per-day indexes and global indexes
for the newly registered time series was decoupled.
Now global indexes and per-day indexes for the current day are created toghether for new time series.
This should speed up registering new time series a bit.

Workers count for merges affects the max part size during merges. Such behaviour
protects storage from running out of disk space for scenario when all workers
are merging parts with the max size.
This works very well for most cases. But for systems where high number of CPUs
is allocated for vmstorage components this could significantly impact the max
part size and result in more unmerged parts than expected.
While checking multiple production highly loaded setups it was discovered that
`max_over_time(vm_active_merges{type="storage/big}[1h]}"` rarely exceeds 2,
and `max_over_time(vm_active_merges{type="storage/small}[1h]}"` rarely exceeds 4.

docs: update docs for beginners
QuickStart page was updated with more relevant information.
Key Concepts was added to cover basics for the VictoriaMetrics.
Unexpectedly, Grafana makes an extra request to `/rules`
handler in addition to `/api/v1/rules` calls in alerts UI.
This happens only for Grafana versions older than 8.5.*.
Apparently, this is related to support of other monitoring
systems.
Prometheus responds with `text/html` content for UI page `/rules`
to such requests. Actually, returning just a blank page with
SC=200 works as well.
Returning actual response of `/api/v1/rules`
results in error in Grafana since it expects a `yaml` (?) in response.

`flag{name="remoteWrite.rateLimit", value="500000", is_set="true"} 1`
We are running many instances of vmagent and when creating alerts it is harder than it needs to be when extracting the value from the flag.
With this change it should be easier to monitor how close to the limit we are.
`((100/vmagent_remotewrite_rate_limit{account="account"})*sum (rate(vmagent_remotewrite_conn_bytes_written_total{account="account"}))) and ON (account) flag{name="remoteWrite.rateLimit"} == 1`
Function `ValidateTemplates`, used on the vmalert startup,
is supposed to check whether used templates and functions
in loaded rules are correct. The function was parsing
and executing loaded templates.
However, rules may contain functions which can't be executed
without values (label values or query results), like `slice`.
Because of this, validation for completely valid expression
`{{ slice $labels.job 9 }}` will fail since `$labels.job`
is empty during validation.
This PR updates `ValidateTemplates` function to only parse
templates without executing them.

add progress bars to the VM importer
The new progress bars supposed to display the processing speed per each
VM importer worker. This info should help to identify if there is a bottleneck
on the VM side during the import process, without waiting for its finish.
The new progress bars can be disabled by passing `vm-disable-progress-bar` flag.
Plotting multiple progress bars requires using experimental progress bar pool
from github.com/cheggaaa/pb/v3. Switch to progress bar pool required changes
in all import modes.
The openTSDB mode wasn't changed due to its implementation, which implies individual progress
bars per each series. Because of this, using the pool wasn't possible.

This metric is equivalent to `vm_available_memory_bytes`, but it has better name,
since the metric is related to a process, not VictoriaMetrics itself.
Leave `vm_available_memory_bytes` for backwards compatibility.
To improve compatibility with Prometheus alerting the order of
templates processing has changed.
Before, vmalert did all labels processing beforehand. It meant
all extra labels (such as `alertname`, `alertgroup` or rule labels)
were available in templating. All collisions were resolved in favour
of extra labels.
In Prometheus, only labels from the received metric are available in
templating, so no collisions are possible.
This change makes vmalert's behaviour similar to Prometheus.
For example, consider alerting rule which is triggered by time series
with `alertname` label. In vmalert, this label would be overriden
by alerting rule's name everywhere: for alert labels, for annotations, etc.
In Prometheus, it would be overriden for alert's labels only, but in annotations
the original label value would be available.

* lib/index: reduce read/write load after indexDB rotation
IndexDB in VM is responsible for storing TSID - ID's used for identifying
time series. The index is stored on disk and used by both ingestion and read path.
IndexDB is stored separately to data parts and is global for all stored data.
It can't be deleted partially as VM deletes data parts. Instead, indexDB is
rotated once in `retention` interval.
The rotation procedure means that `current` indexDB becomes `previous`,
and new freshly created indexDB struct becomes `current`. So in any time,
VM holds indexDB for current and previous retention periods.
When time series is ingested or queried, VM checks if its TSID is present
in `current` indexDB. If it is missing, it checks the `previous` indexDB.
If TSID was found, it gets copied to the `current` indexDB. In this way
`current` indexDB stores only series which were active during the retention
period.
To improve indexDB lookups, VM uses a cache layer called `tsidCache`. Both
write and read path consult `tsidCache` and on miss the relad lookup happens.
When rotation happens, VM resets the `tsidCache`. This is needed for ingestion
path to trigger `current` indexDB re-population. Since index re-population
requires additional resources, every index rotation event may cause some extra
load on CPU and disk. While it may be unnoticeable for most of the cases,
for systems with very high number of unique series each rotation may lead
to performance degradation for some period of time.
This PR makes an attempt to smooth out resource usage after the rotation.
The changes are following:
1. `tsidCache` is no longer reset after the rotation;
2. Instead, each entry in `tsidCache` gains a notion of indexDB to which
they belong;
3. On ingestion path after the rotation we check if requested TSID was
found in `tsidCache`. Then we have 3 branches:
3.1 Fast path. It was found, and belongs to the `current` indexDB. Return TSID.
3.2 Slow path. It wasn't found, so we generate it from scratch,
add to `current` indexDB, add it to `tsidCache`.
3.3 Smooth path. It was found but does not belong to the `current` indexDB.
In this case, we add it to the `current` indexDB with some probability.
The probability is based on time passed since the last rotation with some threshold.
The more time has passed since rotation the higher is chance to re-populate `current` indexDB.
The default re-population interval in this PR is set to `1h`, during which entries from
`previous` index supposed to slowly re-populate `current` index.
The new metric `vm_timeseries_repopulated_total` was added to identify how many TSIDs
were moved from `previous` indexDB to the `current` indexDB. This metric supposed to
grow only during the first `1h` after the last rotation.

This should improve data ingestion speed if time series samples are ingested with interval bigger than 2 minutes.
The actual interval could exceed 2 minutes if the original interval between samples doesn't exceed 2 minutes
in the case of slow inserts. Slow inserts may appear in the following cases:
* Big number of new time series are pushed to VictoriaMetrics, so they couldn't be registered in 2 minutes.
* MetricName->tsid cache reset on indexdb rotation or due to unclean shutdown.
In this case VictoriaMetrics needs to load MetricName->tsid entries for all the incoming series from IndexDB.
IndexDB uses the block cache for increasing lookup performance. If the cache has no the needed block,
then IndexDB reads and unpacks the block from disk. This requires an extra disk read IO and CPU.
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2007
This also should increase performance for periodically executed queries with intervals from 2 minutes to 5 minutes.

It is possible that the timeout can be increased further. Let's collect production numbers for this change
so the timeout could be adjusted further.
Previously limits for new caches were taken from cache stats.
These limits could mismatch the original limits. This could result in failed cache load
if the stored cache has been created with the limits obtained from cache stats.

Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice.
This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed
after slize resizing. Switch such places to bytesutil.ResizeNoCopy().
Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability.
Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice
exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls.
This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache).

- Optimize Cache.RemoveBlocksFromPart(), so it doesn't need to iterate over all the cached blocks.
- Cache blocks if there were no cache misses during the last 2 minutes.
This may be the case when new blocks are added simultaneously to the storage and to the cache.

Previously these caches could exceed limits set via `-memory.allowedPercent` and/or `-memory.allowedBytes`,
since limits were set independently per each data part. If the number of data parts was big, then limits could be exceeded,
which could result to out of memory errors.

On import process interruption `vmctl` now prints the max and min timestamps of:
* last failed batch if import ended with error;
* last sent batch if import was cancelled by user.
To get more details for each timeseries in batch user needs to specify `--verbose` flag.
The change does not relate to `vm-native` mode, since `vmctl` has no control over
transferred data in this mode.

The exported data isn't de-duplicated by default due to performance reasons.

Previously, vmalert would print an err message and set vmalert_config_last_reload_successful=0
only once during a hot reload of a bad config. Such behaviour may result into non noticed

For a long time notifier.Addr flag was required. The assumption was that vmalert will
be always used for alerting. However, practice shows that some users need only
recording rules. In this case, requirement of notifier.Addr is ambigious.
The change verifies if loaded config contains recording or alerting rules and
if there are corresponding flags set. This is true for initial config load
and hot reload.

This removes the unneeded level of indirection and improves code readability.
The "prometheus" and "graphite" constants aren't going to change in the future, so there is no sense in hiding them behind constants.
This should improve the maximum data ingestion speed for highly-loaded vmagent instances
which run on beefy servers with many CPU cores and big amounts of RAM
Previously only the lower part of 64-bit hash was used for calculating the offset.
This may give uneven distribution in some cases. So let's use all the available 64 bits from the hash
for calculating the offset.
Prometheus allows to have groups with no rules, so we should support
it in vmalert as well for compatibility reasons.
It is also allowed to hot-reload empty groups by adding or removing rules.
