Some influx clients ( such as nimon monitoring client) adds excess white spaces in the influx line and does not set a
timestamp. Since Influx protocol requires whitespace before timestamp only when it set, it could present without timestamp. Whitespace before omitted timestamp confuses parser.
This commit adds check for the skipped timestamp and test case for it.
Fixes: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10049
Previously, proxy vmselect (aka 1st level vmselect) performed parsing
of MetricBlock received from vmstorage before forwarding it into top vmselect. It required an additional CPU and Memory, which greatly slowed down query requests.
This commit changes lib/vmselectapi iterator API, instead of MetricBlock, it returns encoded MetricBlock as a byte slice.
It allows to save CPU and memory at proxy vmselect by eliminating need of decoding MetricBlock received from storage.
In addition, it adds the following optimizations for proxy vmselect:
* reduces memory allocations by using iterator pool
* add per storageNode workerItem for iterator
Also, it adds optimization for vmstorage, it no longer performs extra memory copy of MetricName for MetricBlock.
vmselect and vmstorage metrics vm_vmselect_metric_rows_read_total and vm_metric_rows_read_total were removed, it's not used at any dashboards and rules. New Iterator API doesn't support it.
Fixes https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9899
The purpose of this PR is the same as #10000, except `lrucache` is used

A throttled logger will continue to log messages occasionally with a
suffix indicating how many similar logs were throttled. Using the same
logger for multiple log messages can result in certain logs being
entirely suppressed and invisible in the logs. This updates most of the
loggers used in `appendFromScopeMetrics` to be their own logger so that
"unsupported delta temporality/metric type" logs will be visible for all
metric types. Additionally, `skippedSampleLogger` is only used by
`appendSamplesFromHistogram` so this was moved closer to that function.

Go runtime executes all the goroutines on GOMAXPROCS operating system threads.
Go runtime cannot switch the OS thread to another goroutine if the current goroutine
is stuck in the major pagefault while reading the data from memory-mapped file,
because Go runtime doesn't distiguinsh between reading from regular memory and reading
from memory-mapped file. So the OS thread becomes stuck while waiting until the OS
reads the data from file at the requested memory address and returns back control to Go application.
In the worst case it is possible that all the GOMAXPROCS threads are stuck in major pagefaults,
so Go runtime pauses executing all the goroutines. This state is possible in environments
with small GOMAXPROCS and high-latency disks such as NFS or small HDD-based disks at AWS.
See https://valyala.medium.com/mmap-in-go-considered-harmful-d92a25cb161d for more details.
This commit protects from such stalls by verifying whether the given memory location from memory-mapped file
is already loaded in the OS page cache before reading from that memory.
If the location isn't in the OS page cache, then it falls back to pread() syscall for reading the data from file.
Go runtime allocates extra OS threads for long-running syscalls, so it can continue executing goroutines
across all the GOMAXPROCS threads while reading the data from slow storage via pread() syscall.
This commit uses mincore() syscall for detecting whether the given memory page is available in the OS page cache.
It also caches mincore() results for up to a minute in order to reduce the overhead for the mincore() syscall.
This commit reduces the increase rate for the process_major_pagefaults_total metric by multiple orders of magnitude
on systems with high-latency disks.
Currently, `lrucache.Cache` `SizeBytes()` and `SizeMaxBytes()` return
type is `int`. The cache `Entry.SizeBytes()` also returns `int` value.
Changing the type to `uint64` will allow using `uint64set.Set` as the
cache entry type (see #10072).
Please note that using `uint64` regardless the cpu architecture is set
is not entirely correct, because in 32-bit systems the size won't ever
get bigger than `2^32`, so the `uint64` will too much. However current
type (`int`) is not correct either since it is signed and will only
allow to store values up to `2^31`. Alternatively, all `SizeBytes()`
methods should return `uint`.

Currently, when a partition is created its corresponding parts.json file
is not created right away (see createNewParition()). Its creation is
delayed until the first part files are created on disk (see
swapSrcWithDstParts()). However, the parts.json file is created for a
possibly empty partition when an existing partition is opened (see
mustOpenPartition()) and when a partition snapshot is create (see
MustCreateSnapshotAt()).
I.e. `parts.json` is an important part of a partition, since it is an
artifact that describes the partition contents. And it should be created
on pt creation even if its contents is empty.
To be honest, this change is mostly a no-op for the current storage
implementation. It only makes the code consistent, i.e. the parts.json
is created along with the partition.
However having it created when a partition is created becomes in
pt-index (#7599, #8134), because it allows having partitions with no
data and therefore without parts.json file. Still not a big deal but the
unit tests start failing.

Looks like the `dateMetricIDCache` must be per indexDB:
- the use of this cache and `is.hasDateMetricID()` often go in pairs. So
it makes
sense to use this cache in that method.
- The same is true for `createPerDayIndexes()`: everytime the index
entry is
created, a corresponding entry is added to the cache.
- As a result the generation field is also removed from the cache.

This is very frequent question from new users of VcitoriaMetrcs who migrate from other solutions
with automatic data rebalancing among storage nodes, so it is a good idea to cover it in the docs.
Metrics metadata is loaded from a per-tenant storage map
(perTenantStorage map[uint64]map[string]*Row), so result rows order is
non-deterministic. The existing sortRows implementation only sorts by
metric name and ingestion time, which means rows that differ only by
tenant/account ID still sorted undeterministically.
This change updates `sortRows` to include account\project identifiers in
the comparison, ensuring stable and deterministic ordering for metadata
entries that share the same metric name and timestamp.

This commits adds storage part and cluster RPC methods for metrics metadata.
Key concepts:
* vmstorage persists metadata in-memory only.
* vmstorage evicts metadata records older than 1 hour.
* vmstorage stores only the last value of metadata for time series
metric name.
* vminsert opens an additional TCP connection to the vmstorage for
metadata write requests.
* vmselect doesn't support `limit_per_metric_name`.
This feature is available optional and must be enabled via flag - `-enableMetadata` provided to vminsert/vmsingle.
Fixes github.com/VictoriaMetrics/VictoriaMetrics/issues/2974
vmstorage nodes work perfectly with one CPU core and even with 10% of a single CPU core
if the allocated CPU resources matches their workload.
It is better to recommend allocating the an interger number of CPU cores to vmstorage
in order to achieve an optimal performance, since vmstorage allocates internal resources
according to the available CPU cores. If there is a fractional number of CPU cores,
then the allocation of internal resources may be not so optimal.
Fractional number of CPU cores may also lead to increased latencies and stalls
because some P threads at Go runtime won't be able to run goroutines from their ready queues
in a timely manner becasue of the lack of CPU time. See https://victoriametrics.com/blog/kubernetes-cpu-go-gomaxprocs/
Too big values for the -maxConcurrentRequests command-line flag increase memory usage
and increase CPU overhead for processing incoming requests in most cases.
The only valid reason for increasing the value for -maxConcurrentRequests command-line flag
is when many clients send data to vmagent over very slow network.
Previously, zstd Decoder didn't take in account Request Size limits
applied by VictoriaMetrics components. And in case of incorrectly formed zstd block, VictoriaMetrics
component may allocate extra memory. Which may lead to the OOM errors.
This commit makes ingest endpoints check frame content size and window size headers based on MaxRequest Limits.
For users, if an alerting rule has a misconfigured annotation, it's more
important to deliver the alert when the rule triggers rather than skip
it with templating error logs.
Then users can see the faulty annotation in alert message and fix it.
Note: the previous behavior is retained in replay mode because errors
there should be noticed immediately; hiding them could waste time,
resources and require a re-replay after fixes.
Also the rule's status in the vmalert UI remains unhealthy if templating
failed.
fixes https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9853
In prometheus ecosystem, a label with an empty value equals no label,
since a query like `test{something=""}` matches all the series without
label `something`.
So for vmalert, preserving empty-value labels in generated alerts or
time series is unnecessary and can cause alert hash mismatches during
[restore](https://docs.victoriametrics.com/victoriametrics/vmalert/#alerts-state-on-restarts).
The empty-value label shouldn't come from datasource response since they
follow the same rule(omit empty-value labels), it may come from
`-external.label` or rule labels, but the empty value could be caused by
occasionally templating failures, which is hard to check there.
fixes https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9984
This is a follow-up for the commit 1130adebad .
The EntriesCount, BytesSize and MaxBytesSize metrics must take into account the data
stored in both prev and curr caches, since this data occupies memory and it is expected
that the exposed metrics - vm_cache_entries, vm_cache_size_bytes and vm_cache_size_max_bytes -
take into account all the memory occupied by the corresponding caches.
The GetCalls, SetCalls, Collisions and Corruptions metrics must take into account stats
from the curr cache only, since the corresponding stats for the prev cache is already taken
during the rotation (when moving curr to prev and resetting the previous prev).
The Misses metric must take into account only misses in the prev cache, since these misses
mean that the given entry is missing the both the curr and the prev cache.

While at it, make sure that the cache mode and cache stats is always read and updated under c.mu lock.
This may help resolving races similar to https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9921
This reverts commit 89fd27c922.
Reason for revert: this commit adds scalability bottleneck in the fast path - Cache.Get() -
in the form of c.getCalls.Add(). This call doesn't scale on systems with big number of CPU cores,
since it needs to update atomically a shared memory from big number of CPU cores.
The Cache.Get() is called per every ingested sample when obtaining TSID by MetricName from the cache
at lib/storage.Storage.get(), so this can be a major bottleneck on systems with many CPU cores.
The solution for https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9553
is to properly track cache requests and misses: cache requests must be taken into account
only at the curr cache, while cache misses must be taken into account only at the prev cache.
This will be implemented in the follow-up commit.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/9657
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9715
This reverts commit 994dadb4d5.
Reason for revert: the introduced metrics have zero practical applicability.
The lib/workingsetcache doesn't need manual tuning in most cases - its' size
is automatically adjusted to the given working set, if the working set is smaller
than the cache size limit set at the cache creation time. The limit just prevents
unbounded cache growth for large working sets.
If the working set exceeds the given limit, then the cache may become inefficient
because of the increased cache miss rate. The introduced metrics do not help determining
the needed cache size.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/9293
If the cache cannot be saved to the given file, this is a fatal error.
It is better to log this fatal error inside Cache.MustSave() and then exit
instead of returning it to the caller. This makes the code more clear at the caller side.
It is expected that the number of TSIDs misses over the last 5 minutes is zero in steady state.
If it is non-zero, then something wrong happens. That's why it is better to use increase() instead of rate() function
for this alert.
This alert is expected after unclean shutdown (OOM, power off, kill -9) of VictoriaMetrics.
It should go away in a few minutes after the restart while VictoriaMetrics deletes metricIDs
for the missing MetricID->TSID entries which were created for the newly registered time series
just before unclean shutdown. It is OK to delete such metricIDs, since the corresponding time series
will be re-registered again. See the commit 20812008a7 .
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3502
When one goroutine attemps to update the min timestamp under the lock it
could have been updated already by another goroutine with a smaller
timestamp. As a result the goroutine will update the timestamp with a
bigger value.
A simple unit test (included in this commit) demonstrates that.
Additionally, use a simple Mutex instead of RWMutex. RWMutexes only
introduce an unnecessary overhead for operations as simple as retrieving
a value from a map and regular Mutex should be preferred.
Thanks to @valyala for spotting a bug and the advice on RWMutexes.

When multiple service discovery configs of the same type exist (e.g.,
`hetzner_sd_config`), vmagent currently behaves as follows:
1. Attempts to request each config.
2. Exits immediately if any config returns an error.
3. Skips the rest configs and falls back to the previous service
discovery result.
The correct behavior—more compatible with Prometheus—should be:
1. Attempt to request each config.
2. Collect all valid results.
3. Use the valid results if there's at least one. otherwise (all
failed), fall back to the previous SD result.
Scrape example:
```yaml
scrape_configs:
- job_name: hetzner-default
hetzner_sd_configs:
- role: "hcloud"
authorization:
credentials: "some_valid_value"
- role: "hcloud"
authorization:
credentials: "some_wrong_value"
```
Expected outcome:
- At least targets from `credentials: "some_valid_value"` should appear
in the service discovery result.
current outcome:
- the error from `credentials: "some_wrong_value"` leads to an **empty**
result.
This issue should affect service discovery which using

```
this design decision isn't good, since it will lead to potential security issues over time when we'll forget adding ApplySecretFlags() call after the flag.Parse() call or add it at the wrong place. BTW, we do not call flag.Parse() explicitly - instead envflag.Parse() is called. So it is natural to call ApplySecretFlags() inside this call. Are there restrictions which prevent from doing this? If there are no restrictions, then there is no need in making this function public - it will be called explicitly inside envflag.Parse().
```

vmalert tries to spread the moment group starts its evaluation
on `[0..group.interval]` duration. This approach allows to avoid
thundering herd problem when on vmalert start all groups execute their
rules simultaneously. It was introduced in
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/724
While for most configs it works great, for groups with big evaluation
intervals (30min, 60min) the first evaluation can be delayed
significantly.
This change introduces a start delay limit via new flag
`--group.maxStartDelay` (5m default).
It limits the `[0..group.interval]` start delay to
`[0..math.min(--group.maxStartDelay, group.interval)]`.
So all groups will start in first 5m or earlier.
The --group.maxStartDelay is ignored if user set `eval_offset`.
The 5m default limitation was picked high to not affect users with
relatively low evaluation intervals.

with long-running queries. In this case the major load goes to the backend after a row of busy backend.
Suppose we have four backends - b1, b2, b3 and b4. The first two backends are busy with bigger number
of long-running queries than b3 and b4. Then 75% of short queries will go to b3, while only 25%
of short queries will go to b4.
The new algorithm makes the distribution more even in these cases by storing the next backend
after the chosen backend as candidate for the next query (its' index is stored in the atomicCounter).
Avoid races when updating atomicCounter from concurrently executed queries by using CompareAndSwap() -
if the concurrent query updated it first then the current query won't overwrite it with the outdated value.

Data patterns considered:
- Same series, same date
- Same series, different dates
- Different series, same date
- Different series, different dates
To make sure that the pattern condition holds, a new storage instance is
started every benchmark iteration.

Previously, vmctl only accepted one label for filtering. Extend this to
allow providing multiple-filters at once. This is useful when migrating
large volumes of data as it allows narrowing down migration scope of
migration for one run so that the source side is not overwhelmed with
migration.

Before, rules that didn't get evaluated yet were showing weird values in
vmalert's UI. It was happening because of
`time.Since(r.LastEvaluation).Seconds()` expression when
`r.LastEvaluation` had 0 value.
With this change, rules that weren't evaluated yet would show `Never` in
Updated column instead.

This commit request revert the commit
d6bbfaf164 for the following reasons:
1. HTTP/2 carries security risks.
2. Most components in the VictoriaMetrics stack do not require HTTP/2
support.
3. While HTTP/2 support was available only as an option in previous
commit, there remains a potential risk of misusing this option and
enabling HTTP/2 inadvertently.
For components (e.g., VictoriaTraces) that require HTTP/2 support, they
should currently build an HTTP server manually with built-in packages,
instead of using `lib/httpserver` in VictoriaMetrics. If the mentioned
issue is resolved in the future and more components need HTTP/2, this
support can be reintroduced into `lib/httpserver`.

Rationale: Having query stats logging enabled by default can greatly
help in investigating incidents.
Currently, it is disabled by default, so many users don’t enable it, and
when issues occur there are no stats available.
After discussion with the team, a 5s threshold was agreed upon as a
reasonable default to capture meaningful slow query data without
excessive logging.
This commit adds new RPC protocol for vminsert-vmstorage communication,
it acts in the same way as vmselect-vmstorage RPC.
It's implemented with new handshake hello methods in a backward
compatible way. Server attempts to parse RPC only if client send new
Hello message, while client fallbacks to the old Hello message if server
closes connection.
This change is need for the new metrics metadata forwarded from vminsert
into vmstorage.

Previously, if a storage started with curr indexDB different from one
stored in nextDayMetricIDs cache file, the cache would still be loaded
into memory possibly affecting the next day prefill.
This is an unlikely case but it is still possible when:
- A programmer makes a mistake in the code and uses something else
instead of idbCurr.generation.
- Downgrading from pt-index to previous version

This change validates that QueryRange() method for prometheus datasource
receives response with `matrix` data type. It would throw an error
otherwise.
The change is needed to avoid confusions like in
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9779.
The fix is not elegant, but it should be simple from code support
perspective. So each API has its own parsing function. Even if some
processing code is repeated.

Currently, the `httpserver` disabled HTTP/2 support by design, because:
```
// Disable http/2, since it doesn't give any advantages for VictoriaMetrics services.
```
As VictoriaLogs and VictoriaTraces rely on `httpserver`, in order to
support gRPC over HTTP/2, an option to support HTTP/2 is required.

Previously all timeseries pushed into aggregators were added
sequentially. It could cause delays on data ingestion and it was not
possible to use all available.
This commit adds concurrency based on available CPU cores.
Also, it adds new generic Buffer and BufferPool into slicesutil.
Fixes https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9878
Previously a misleading random error could be logged for canceled and/or timed out requests to vmauth.
Consistently log the request timeout error for timed out requests.
While at it, do not log errors for requests canceled by the remote client, since such logs aren't actionable
and just pollute error logs generated by vmauth.
Introduce a new flag, which converts only metric names into Prometheus
compatible format. And keeps label names in original form.
It's needed to keep labels in original form, which
is useful for correlation with other telemetry sources, such as logs or
traces.

Tracking original labels requires storing a copy of labels obtained
from service discovery. It adds extra Garbage Collection pressure and as
a result increased CPU usage.
While dropOriginalLabels has almost no impact at test and small
installations.
Impact grows with a scale. And especially is impactful at Kubernetes
based installations.
In addition, this flag is disabled by default for `k8s-stack` helm
chart, which is our main Kubernetes monitoring solution.
An also, we recommend at vmagent optimisation guide to disable original
labels storing.
This commit changes default value to true and disables tracking of
dropped targets by default. In case of debugging, it could be easily
enabled back by providing `false` value to the flag:
`promscrape.dropOriginalLabels`. It should improve resource usage out of
box by reducing user-experience for minority of users.

page</a> for the relevant changes to the CodeQL CLI and language
packs.</p>
<h2>3.30.4 - 25 Sep 2025</h2>
<ul>
<li>We have improved the CodeQL Action's ability to validate that the
workflow it is used in does not use different versions of the CodeQL
Action for different workflow steps. Mixing different versions of the
CodeQL Action in the same workflow is unsupported and can lead to
unpredictable results. A warning will now be emitted from the
<code>codeql-action/init</code> step if different versions of the CodeQL
Action are detected in the workflow file. Additionally, an error will
now be thrown by the other CodeQL Action steps if they load a
configuration file that was generated by a different version of the
<code>codeql-action/init</code> step. <a
href="https://redirect.github.com/github/codeql-action/pull/3099">#3099</a>
and <a
href="https://redirect.github.com/github/codeql-action/pull/3100">#3100</a></li>
<li>We added support for reducing the size of dependency caches for Java
analyses, which will reduce cache usage and speed up workflows. This
will be enabled automatically at a later time. <a
href="https://redirect.github.com/github/codeql-action/pull/3107">#3107</a></li>
<li>You can now run the latest CodeQL nightly bundle by passing
<code>tools: nightly</code> to the <code>init</code> action. In general,
the nightly bundle is unstable and we only recommend running it when
directed by GitHub staff. <a
href="https://redirect.github.com/github/codeql-action/pull/3130">#3130</a></li>
<li>Update default CodeQL bundle version to 2.23.1. <a

This reverts commit 772ac8803e.
The reason for revert is that this recommendation should not be strict.
Installations with <= 1 vCPU will continue working efficiently. The load
from reads, writes and background merges will be evenly spread by Go runtime.

Reverts 17ca1ba8c4
Reason for reverts are following:
1. The fix relies on release candidates of specific libraries
2. The real fix would be to update Alpine version, which is not released yet
3. It makes the fix partially done, as it would require follow-up in future to
switch from release candidates to stable versions, or to update Alpine version.
4. The fix is not effective, as it doesn't update the base image cached by Docker.
The real fix will be to host&update the base image separately like in https://github.com/VictoriaMetrics/VictoriaMetrics/pull/9811.
5. VM binaries aren't vulnerable to mentioned vulnerabilites.
