Regression was introduced at 564e6ea024
after implementing:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6928
ctx.Labels array could be incorrectly updated and changes to it after
relabeling rules can be lost.
E.g. ctx.Labels passed to WriteDataPoint function as slice copy, but
results of relabeling only changed an actual slice at ctx.Labels.
This commit replaces implicit relabeling call with explicit
`TryPrepareLabels` function.
It also reduces code diffs with cluster version and adds integration tests

While at at, allow passing an array of string values per each JSON entry at extra_filters and extra_stream_filters.
For example, `extra_filters={"foo":["bar","baz"]}` is converted into `foo:in("bar", "baz")` extra filter,
while `extra_stream_fitlers={"foo":["bar","baz"]}` is converted into `{foo=~"bar|baz"}` extra filter.
This should simplify creating faceted search when multiple values per a single log field must be selected.
This is needed for https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7365#issuecomment-2447964259
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5542
Such log fields do not give any useful information during logs' exploration.
They just clutter the output of the `facets` pipe. So it is better to drop such fields by default.
If these fields are needed, then `keep_const_fields` option can be added to `facets` pipe.
This PR fixes#5796. See the points 6 and 7 in `Steps to reproduce`:
> Now let's set time to only 5ms past the timestamp of the first point,
since even 199ms worked for the second point. Surprise, the point isn't
returned 💥:
>
> ```curl -s $VMQURL -d 'query=series1' -d 'time=1707123456705' -d
'step=1ms' | grep 10 # nothing!```
>
> But, 4ms works: 🤨🤔
>
> ```curl -s $VMQURL -d 'query=series1' -d 'time=1707123456704' -d
'step=1ms' | grep 10 # found```
This happens so because the actual step becomes 5ms due to jitter being
applied. THe fix is to do not apply jitter if scrape interval was not
detected (the case when vmstorage returns only one result). In this case
the scrape interval is set to `5m+step`.
An integration test has been added to check the steps to reproduce and
then to confirm that fix works. Note that the cluster tests are
currently disabled because the fix is not in cluster branch yet.

Previously after configuration reload call `externalURL` templaing function defined at external templates could be lost. Since it was added only at initial `Load` call and never copied during template reload process.
External templates for vmalert could be defined via `-rule.templates` flag.
This commit properly reload external templates. It's no longer copies mutated templates and instead fully reloads it each time if there is any changes.
Previously cluster with the following vmselect configuration:
./bin/vmselect
-storageNode=gr1/:8211,gr1/:8212
-storageNode=gr2/:8213,gr2/:8214
-search.skipSlowReplicas=true
-globalReplicationFactor=2
Here we have two vmstorage groups and -globalReplicationFactor=2, which effectively means that "every ingested sample is replicated across multiple vmstorage groups". Hence, gr1 and gr2 contain identical data set. And when we set -search.skipSlowReplicas=true it is expected vmselect should return result as soon as at least one storage group returned the full result.
In current state, -search.skipSlowReplicas is ignored on the storage group level. It is only respected within the group (with -replicationFactor flag).
This commit fixes global replication for skipSlowReplicas.
To ensure that the fix works and does not break
anything replication tests have been added. For checking the fix for
skipping slow replicas see `testGroupSkipSlowReplicas()`.
To emulate storage groups, the integration test creates a cluster with
multilevel vminsert. The L1 inserts are group-level inserts, each writes
to its own group of vmstorages. The L2 vminsert is a global vminsert
that writes replicated to the L1 vminserts.
To enable multilevel inserts changes in apptest framework and
`lib/ingestserver/clusternative/server.go` were necessary.

(cherry picked from commit 87c1b2de6f)
Previously, time series with labels exceeding the configured limits were truncated and written to storage, potentially causing data inconsistency. This could lead to collisions between time series and make it difficult to identify the source due to truncated labels.
This commit changes the behavior:
* Such time series are now rejected outright.
* Rejected time series are logged to stdout, and corresponding counters are incremented.
* removes `vm_too_long_label_values_total`, `vm_too_long_label_names_total`, `vm_metrics_with_dropped_labels_total` metrics.
* adds new values `[too_many_labels,too_long_label_name,too_long_label_value]` to `reason` label of the `vm_rows_ignored_total` metric name

Previous commit b09272ccac added regression, which could lead to the template
global state overwrites.
The issue related to the mechanism how `vmalert` inherits templates. It has global templates, that could be changed via `rule.templates` flag. And local templates defined per labels/annotations for rules and groups.
During labels/annotations templating state could be changed via `define` syntax.
This commit restores previous behavior with `Clone` call for templates before templating labels/annotations.

This commit adds ability to launch vmauth without configuration file.
Which is possible use case for operator based installations.
Operator provides global resource `VMAuth` and allows to create
`VMUser` objects for it. Eventually operator creates configuration for
`VMAuth` based on user defined selectors for `VMUser`.
Since there is no direct relations between
those objects. And any object could be created in on-demand by
Kubernetes users. It's required to be able to start `vmauth` with empty
auth config file.

The max_value_len query arg allows controlling the maximum length of values
per every log field. If the length is exceeded, then the log field is dropped
from the results, since it contains incomplete (misleading) set of most frequently seen field values.
(cherry picked from commit 48540ac409)
This endpoint returns the most frequent values per each field seen in the selected logs.

Requests processed by built-in HTTP server has the [origin
form](https://datatracker.ietf.org/doc/html/rfc7230#section-5.3) rather
than the absolute form.
So in[Request.URL](https://pkg.go.dev/net/http#Request), fields other than
Path and RawQuery will be empty.
> // For server requests, the URL is parsed from the URI
> // supplied on the Request-Line as stored in RequestURI. For
> // most requests, fields other than Path and RawQuery will be

Using `request.Host` field instead to match `src_hosts` fixes issue and allows to route requests properly.
An addition It allows user to route requests with customized `Host` header.
The storage isn't designed to work efficiently with logs containing too many log fields.
It is better to emit a warning to the user and ignore such logs instead of trying to store them.
This will allow fixing the issue by the user ASAP, and won't lead to excess resource usage
at VictoriaLogs side, such as RAM, CPU, disk IO and disk space.
While at it, ignore too long logs with the size exceeding the maximum block size during data ingestion.
This should prevent from possible issues when dealing with such long logs if they were stored in the storage.
Emit a warning in this case, so the user could identify and fix the issue ASAP.

Previously vl_rows_ingested_total metric was tracked individually per each supported data ingestion protocols.
It is better from maintainability PoV tracking this metric consistently in a single place - at logMessageProcessor.AddRow() function

This is a follow-up for 50bfa689c9
This metric tracks an approximate amounts of bytes processed when parsing the ingested logs.
The metric is exposed individually per every supported data ingestion protocol. The protocol name
is exposed via "type" label in order to be consistent with vl_rows_ingested_total metric.
Thanks to @tenmozes for the initial idea and implementation at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7682

Previously, vmagent produced parsing error for 'multitenant' auth token
value for the cases:
* data ingestion with enableMultitentEndpoints
* data scrapping at promscrape
It's inconsistent to the other VictoriaMetrics components.
Since 'multitenant' is well-known token value for multitenancy via
labels. And vmagent is intended to be compatible with vminsert ingestion
endpoints.
This commit replaces NewToken with NewTokenPossibleMultitenant function
for token parsing. It allows to use multitenant value for it. And it
makes token values consistent for the all components.

Previously, there was no option to replace value of `X-Forwarded-For`
HTTP Header. It was only possible to completely remove it. It's not good
solution, since backend may require this information. But using direct
value of this header is insecure. And requires complex knowledge of
infrastruce at backend side (see spoofing X-Forwarded-For articles).
This commit adds new flag, that replaces content of `X-Forwarded-For`
HTTP Header value with current `RemoteAddress` of client that send
request.
It should be used if `vmauth` is directly attached to the internet.

doing similar changes for both vmagent and vminsert (like one in
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7399) ends up
with almost same implementations for each of packages instead of having
this shared code in one place. one of the reasons is the same Timeseries
and Labels structure from different prompb and prompbmarshal packages.
My proposal is to use structures from prompb package only to
marshal/unmarshal sent/received data, but for internal transformations
use only structures from prompbmarshal package
Another example, where it already can help to simplify code is streaming
aggregation pipeline for vmsingle (now it first marshals
prompb.Timeseries to storage.MetricRow and then if streaming aggregation
or deduplication is enabled it unmarshals all the series back but to
prompbmarshal.Timeseries)

1. Avoid storing the last evaluation results outside of rules, check for

2. remove duplicated template `Clone()`.
This pull request is primarily reducing memory usage when rules produce

The CPU time spent on garbage collection remains high and may be
addressed in a separate PR.

The fix at a0a154511a looks too complicated and fragile:
- It moves buMin initialization to the place, which is far from its usage.
- It embeds unclear logic on selecting the proper buMin if it is broken,
into unrelated loop.
The actual fix must be more clear:
$ git diff 95acca6b52 -- app/vmauth/
- if n := bu.concurrentRequests.Load(); n < minRequests {
+ if n := bu.concurrentRequests.Load(); n < minRequests || buMin.isBroken() {

Previously, vmauth could have pick `buMin` as least loaded backend
without checking its status. In result, vmauth could have respond to the
user with an error even if there were healthy backends. That could
happen if healthy backends already had non-zero amount of concurrent
requests executing at the moment of least-loaded backend choosing logic.
Steps to reproduce:
1. Setup vmauth with two backends: healthy and non-healthy
2. Execute a bunch of concurrent requests against vmauth (i.e. Grafana
dash reload)
3. Observe that some requests will fail with message that all backends
are unavailable

### Describe Your Changes
Fix https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7301
When querying with condition like `WHERE a=1` (looking for series A),
InfluxDB can return data with the tag `a=1` (series A) and data with the
tag `a=1,b=1` (series B).
However, series B is will be queried later and it's data should not be
combined into series A's data.
This PR filter those series that are not identical to the original query
condition.
For table `example`:
```
// time host region value
// ---- ---- ------ -----
// 2024-10-25T02:12:13.469720983Z serverA us_west 0.64
// 2024-10-25T02:12:21.832755213Z serverA us_west 0.75
// 2024-10-25T02:12:32.351876479Z serverA 0.88
// 2024-10-25T02:12:37.766320484Z serverA 0.95
```
The query for series A (`example_value{host="serverA"}`) and result will
be:
```SQL
SELECT * FROM example WHERE host = "serverA"
```
```json
{
"results": [{
"statement_id": 0,
"series": [{
"name": "cpu",
"columns": ["time", "host", "region", "value"],
"values": [
["2024-10-25T02:12:13.469720983Z", "serverA", "us_west", 0.64],
["2024-10-25T02:12:21.832755213Z", "serverA", "us_west", 0.75],
["2024-10-25T02:12:32.351876479Z", "serverA", null, 0.88],
["2024-10-25T02:12:37.766320484Z", "serverA", null, 0.95]
]
}]
}]
}
```
We need to abandon `values[0]` and `values[1]` because the value of
**unwanted** column `region` is not null.
As for series B (`example_value{host="serverA", region="us_west"}`), no
change needed since the query filter out unwanted rows already.

- add a separate index cache for searches which might read through large
amounts of random entries. Primary use-case for this is retention and
downsampling filters, when applying filters background merge needs to
fetch large amount of random entries which pollutes an index cache.
Using different caches allows to reduce effect on memory usage and cache
efficiency of the main cache while still having high cache hit rate. A
separate cache size is 5% of allowed memory.
- reduce size of indexdb/dataBlocks cache in order to free memory for
new sparse cache. Reduced size by 5% and moved this to a separate cache.
- add a separate metricName search which does not cache metric names -
this is needed in order to allow disabling metric name caching when
applying downsampling/retention filters. Applying filters during

not provide an actual improvement due to random access nature.

**Added ability to hide the hits chart**
- Users can now hide or show the hits chart by clicking the "eye" icon
located in the upper-right corner of the chart.
- When the chart is hidden, it will stop sending requests to
`/select/logsql/hits`.
- Upon displaying the chart again, it will automatically refresh. If a
relative time range is set, the chart will update according to the time
period of the logs currently being displayed.

`vm_rows_ignored_total` metric is a metric for users to signalize about
ingestion issues, such as bad timestamp or parsing error.
In commit
a5424e95b3
this metric started to increment each time vmstorage gets NaN. But NaN
is a valid value for Prometheus data model and for Prometheus metrics
exposition format. Exporters from Prometheus ecosystem could expose NaNs
as values for metrics and these values will be delivered to vmstorage
and increment the metric.
Since there is nothing user can do with this, in opposite to parsing
errors or bad timestamps, there is not much sense in incrementing this
metric. So this commit rolls-back `reason="nan_value"` increments.

- /prometheus/api/v1/series
- /prometheus/api/v1/labels
- /prometheus/api/v1/label/<label_name>/values

- /prometheus/api/v1/status/top_queries
- /prometheus/api/v1/status/tsdb
- /prometheus/api/v1/export
- /prometheus/api/v1/export/csv
- /vmui
A note regarding VMUI: endpoints such as `active_queries` and
`top_queries` have been updated to indicate whether query was a
single-tenant or multi-tenant, but UI needs to be updated to display
this info.

then the operation may result in unaccounted CPU and memory usage spikes
which in some cases may result in OOM kill (see #7027). The flag limits
the number to 30k by default and the users may override it if needed at

Use local timezone of the host server in this case. The timezone can be overridden
with TZ environment variable if needed.
While at it, allow using whitespace instead of T as a delimiter between data and time
in the ingested _time field. For example, '2024-09-20 10:20:30' is now accepted
during data ingestion. This is valid ISO8601 format, which is used by some log shippers,
so it should be supported. This format is also known as SQL datetime format.
Also assume local time zone when time without timezone information is passed to querying APIs.
Previously such a time was parsed in UTC timezone. Add `Z` to the end of the time string
if the old behaviour is preferred.

Previously the query could return incorrect results, since the query timestamp was updated with every Query.Clone() call
during iterative search for the time range with up to limit=N rows.
While at it, optimize queries, which find low number of matching logs, while spend a lot of CPU time for searching
across big number of logs. The optimization reduces the upper bound of the time range to search if the current time range
contains zero matching rows.

### Describe Your Changes
Add storage metrics that count records that failed to insert:
- `RowsReceivedTotal`: the number of records that have been received by
the storage from the clients
- `RowsAddedTotal`: the number of records that have actually been
persisted. This value must be equal to `RowsReceivedTotal` if all the
records have been valid ones. But it will be smaller otherwise. The
values of the metrics below should provide the insight of why some
records hasn't been added
- `NaNValueRows`: the number of records whose value was `NaN`
- `StaleNaNValueRows`: the number of records whose value was `Stale NaN`
- `InvalidRawMetricNames`: the number of records whose raw metric name
has failed to unmarshal.
The following metrics existed before this PR and are listed here for
completeness:
- `TooSmallTimestampRows`: the number of records whose timestamp is
negative or is older than retention period
- `TooBigTimestampRows`: the number of records whose timestamp is too
far in the future.
- `HourlySeriesLimitRowsDropped`: the number of records that have not
been added because the hourly series limit has been exceeded.
- `DailySeriesLimitRowsDropped`: the number of records that have not
been added because the daily series limit has been exceeded.

it is better suppressing the warning, so it doesn't clutter `make package-*` output with the noise,

…specifying `-streamAggr.dedupInterval` or

[The
documentation](https://docs.victoriametrics.com/stream-aggregation/)
contains conflicting descriptions regarding deduplication for
non-matched series when `-remoteWrite.streamAggr.config` and / or
`-streamAggr.config` are set:
1. Statement below says **all the received data** is deduplicated:
>[vmagent](https://docs.victoriametrics.com/vmagent/) supports
relabeling, deduplication and stream aggregation for all the received
data, scraped or pushed. Then, the collected data will be forwarded to
specified -remoteWrite.url destinations. The data processing order is
the following:
>1. all the received data is relabeled according to the specified
[-remoteWrite.relabelConfig](https://docs.victoriametrics.com/vmagent/#relabeling)
(if it is set)
>2. all the received data is deduplicated according to specified
[-streamAggr.dedupInterval](https://docs.victoriametrics.com/stream-aggregation/#deduplication)
(if it is set to duration bigger than 0)
2. Another statement says the deduplication is performed individually
for the **matching samples**
>The de-deduplication is performed after applying
[relabeling](https://docs.victoriametrics.com/vmagent/#relabeling) and
before performing the aggregation. If the -remoteWrite.streamAggr.config
and / or -streamAggr.config is set, then the de-duplication is performed
individually per each [stream aggregation
config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config)
for the matching samples after applying
[input_relabel_configs](https://docs.victoriametrics.com/stream-aggregation/#relabeling).
Considering the following deduplication use cases:
1. To apply deduplication(globally or for specific remoteWrite
destination) for all the received data, scraped or pushed
--- using `-streamAggr.dedupInterval` or
`-remoteWrite.streamAggr.dedupInterval`.
2. To deduplicate and aggregate metrics that match the rule `match`
filters
--- using `-remoteWrite.streamAggr.config` and specifiying
`dedup_interval` option in [stream aggregation

add command-line flag `-search.inmemoryBufSizeBytes` for configuring size of in-memory buffers used by vmselect during processing of vmstorage responses. A new summary metric `vm_tmp_blocks_inmemory_file_size_bytes` is exposed to show the size of the buffer during requests processing.
The new setting can be used by experienced users to adjust memory usage by vmselect when processing
many small read requests. Instead of allocating 4MB buffers each time, vmselect can be instructed to lower
the buffer size via `-search.inmemoryBufSizeBytes`. To make the decision whether this flag needs to be adjusted
users can consult with `vm_tmp_blocks_inmemory_file_size_bytes` which shows the actual size of buffers used
during query processing.

(cherry picked from commit d0f5a9d77a)
This change is made in attempt to reduce memory usage by vmalert when
parsing big instant responses from VM/Prometheus.
In
a5c427bac4
vmalert switched from std json lib to fastjson lib in order to reduce
amount of allocations, as according to highloaded profiles of vmalert
the CPU is mostly spent on GC.
But switching to fastjson resulted into excessive memory usage for cases
when vmalert has to parse long json lines, which usually happens when
instant response contains many `metric` objects.
In this change we do a mixed parsing:
1. Slice of `metric` objects is parsed with std lib to keep mem low
2. Each `metric` object is parsed with fastjson to reduce allocs
The benchmark results are the following:

The benchmark function code with mem measurement is available here
https://gist.github.com/hagen1778/b9c3ca7f8ca7d6b21aec9777112c5810
The benchmark contains 3 results:
1. Instant_std+fastjson is the implementation in this change
2. Instant_fastjson-10 is the implementation from
a5c427bac4
3. BenchmarkParsePrometheusResponse/Instant_std-10 is implementation
before
a5c427bac4
According to these results, this new implementation is slower than
previous, but faster than before switching to fastjson. It also has
lower number of allocations and roughly the same memory allocation on
heap with GC turned off.
---------
Other changes:
1. rm BenchmarkMetrics as it doesn't measure anything
2. simplify BenchmarkParsePrometheusResponse into
BenchmarkPromInstantUnmarshal

### Describe Your Changes
Initially vmanomaly opened with `/vmui` in serverUrl, remove it.
(cherry picked from commit 535a9ed059)
to allow configuring additional headers in each request to the
corresponding notifier.
Other flags like `-datasource.headers`, `-remoteWrite.headers` already
use `^^` as delimiter, it's consistent to use it in `-notifier.headers`
as well.

vmalert can integrate with alertmanager that supports multi-tenant by
adding tenantID header`X-Scope-OrgID` in requests.
In multitenancy, vmalert can also filter alerts which send to different
notifier addresses(or with different header settings) using
`alert_relabel_configs`.

(cherry picked from commit 0f1ec33892)
Production workload shows that it's useful optimisation.
Channel based objects pool allows to handle irregural data ingestion
requests and make memory allocations more smooth.
It's improves sync.Pool efficiency, since objects from sync.Pool removed
after 2 GC cycles. With GOGC=30 value, GC runs significantly more often.

Describe Your Changes
When I use usePromCompatibleNaming with vmagent to process data that
needs to be formatted from different sources such as InfluxDB, I find
that it doesn’t work
However, it works in vminsert. I found that vminsert uses the
HasRelabeling method to determine whether to relabel.
```go
func HasRelabeling() bool {
pcs := pcsGlobal.Load()
return pcs.Len() > 0 || *usePromCompatibleNaming
}
```
in vmagent, the decision to relabel is determined only by
pcsGlobal.Len() > 0. However, in the applyRelabeling method, the
usePromCompatibleNaming logic is also used to determine whether to
relabel in the error handling.
```go
func (rctx *relabelCtx) applyRelabeling(tss []prompbmarshal.TimeSeries, pcs *promrelabel.ParsedConfigs) []prompbmarshal.TimeSeries {
if pcs.Len() == 0 && !*usePromCompatibleNaming {
// Nothing to change.
return tss
}
```
So I think that the logic for determining whether to relabel in vmagent
is not as expected.

(cherry picked from commit 62d19369a3)
VM has different responses to equivalent queries for MetricsQL and
GraphiteQL in case of failed access to one of vmstorage node of the
cluster vmstorage nodes. For GraphiteQL, the denyPartialResponse feature
is not used, it is always true, which is not always correct (depending
on the configuration).
In the PR I have removed the hardcoded denyPartialResponse for
GraphiteQL, just like MetricsQL does.
