(cherry picked from commit c0f5699bad)
When vmselect process a rollup function it fetches all the raw samples
on requested `start-end` interval of the query. It then loops through
the raw samples, picks the range of the samples based on provided `step`
interval and invokes a rollup function for each of the picked ranges of
samples.
During this processing, vmselect always populates the `realPrevValue`
field with the closest previous raw sample value before the picked range
of samples. This `realPrevValue` is used by rollup functions like
increase_pure or delta to decide whether the counter change happened or
not. For example, we get the counter value == 1. If we've seen this
counter before and its value was also 1 - then no change happened. If we
didn't see it before, then this counter should have started with value=0
and we need to account for `1-0=1` change. All this is required to deal
with situations when scrapes are missing or `step` is too small.
However, vmselect doesn't check how "old" is the `realPrevValue`. In
other words, it doesn't respect the staleness interval when picking it.
In result, depending on the `start` and `end` params, vmselect can use
`realPrevValue` which is a couple of hours old and is unlikely to be a
temporary scrape fail. In result, some increases can be incorrectly
ingnored by vmselect.
This change makes sure that vmselect doesn't populate `realPrevValue`
with samples that are older than staleness interval.

To reproduce, create a dataset with one metric `foo` which has samples
with value=1 on interval of couple of hours and resolution 15s, and a
gap for an hour in the middle:
<img width="769" alt="image"
src="https://github.com/user-attachments/assets/a39b2740-b741-45f8-ad18-093b7c57c3b3"
/>
Then run `increase(foo[1m])` expression on this time range (disable
cache):
<img width="1472" alt="image"
src="https://github.com/user-attachments/assets/463cece1-f359-4c75-a96c-60092a31cab2"
/>
In result, there will be one increase on the beginning of the series.
And no increase after the gap. Then change the time range so it starts
in the middle of the gap:
<img width="1505" alt="image"
src="https://github.com/user-attachments/assets/f4a460c3-9fd1-4ec7-ab47-15e716ec1019"
/>
Now, there is an increase>0 because the `realPrevValue` wasn't
populated. This is wrong, because it hides the increase of the series.
With the fix, the original increase query on full time range should show
2 increases:

This commit makes configurable interval for checking if final dedup
process for the historical data should be started. It allows to spread
resource utilisation for multiple vmstorage/vmsingle instances in time.
Since final dedup may add additional preasure on disk, backup systems
and make cluster less stable. Storage unconditionally adds 25% jitter to
the provided value, it should simplify configuration management at
Kubernetes ecosystem. Because Kubernetes application pods must have the
same configuration.

Since

`evalNumber` function no longer updating MetricName tenancy information.
This leads to mismatch in metric names between the query result and
evaluated number for all tenants other than 0:0.
For example, query `count(up) or 0` will return different results for
tenants 0:0 and 1:1 (assuming up is present for both tenants):
- tenant 0:0 - will only contain result of `count(up)`
- tenant 1:1 - will return both `count(up)` and `0` since metric names
will not be matched
This restores setting of tenancy information for metric name for
single-tenant queries.

### Describe Your Changes
Binary operations like `exprFirst op exprSecond` in VictoriaMetrics are
performed in the following way:
1. Execute exprFirst.
2. Extract **common label filters** from the result of step 1.
3. Apply these common label filters to `exprSecond` and execute it, in
order to retrieve less time series from vmstorage nodes.
In step 2, only labels with less than `100` (hard-coded) value could be
used as **common label filter** (e.g. `{common_lb=~"v1|v2|...|v100"}`.
In our scenarios, a label, take `instance` label as an example, could
has thousands of candidate values. Regarding bring more pressure to
vmstorage node, it's still beneficial if labels with more than 100
values could be used as filter in `exprSecond`, with enough vmstorage
resources. After adjusting the value from `100` to `10000`, our query
round-trip time drops significantly from 5s to 2s.
This pull request change the hard-coded value into a configurable flag.
storageNode sorting should be BUGFIX, since previously vminsert performed sort and this behaviour was changed.
Also this change only affects OSS version
Parse cache is a pretty simple implementation of cache. It's just a
standard map with mutex.
Map with mutex overall has poor performance, plus when the cache
overflow occurs, the whole cache locks until 1k elements have been
deleted (now it's 10% of 10000 max elements in the cache). To avoid this
bottleneck and improve performance of cache on systems with many CPU
cores but keep it rather simple, we can implement cache with per bucket
locks like it's done in fastcache. The logic and API remain the same. So
now each bucket will have a map with approximately 78 elements (with 128
buckets), and overflow will occur now for each bucket, and only 7
elements need to be deleted.
Because exec_test.go has about 10k lines of code, it's better to move
the cache into a separate file to add tests and benchmarks for it,
because now it does not have them.

But VictoriaLogs can obtain tenant information only from `headers` and defined `tenant` breaks requests to the `VictoriaLogs` datasource.
This commit properly checks `datasourceType` and skips adding path prefix if `datasourceType` is `vlogs`.

previously vmstorage ignored limit values from vmselect component.
This behavior is prohibited starting from v1.105.0, with
85f60237e2.
This breaks the original intent of the -search.maxUniqueTimeseries command-line flag, which has been added at vmselect nodes in the commit b843f0e : to be able to override the default limit at vmstorage on the number of unique time series, at different subsets of vmselect nodes.
The behavior should be the following:
* If -search.maxUniqueTimeseries command-line flag isn't set at both vmselect and vmstorage nodes, then the limit on the number of unique time series must be automatically detected at vmstorage nodes according to
* vmstorage: automatically adjust -search.maxUniqueTimeseries max value . This simplifies configuration of VictoriaMetrics cluster for the typical case.
* If -search.maxUniqueTimeseries command-line flag is explicitly set at vmstorage node, then it must be used as the limit on the number of unique time series, without automatic detection of the limit. Explicitly set limit at vmstorage node cannot be exceeded by the limit from vmselect nodes.
* If the -search.maxUniqueTimeseries command-line flag is explicitly set at vmselect node, then it must override the automatically detected limit at vmstorage node. For example, if vmselect node provides the limit, which exceeds the automatically detected limit at vmstorage node, then the limit from the vmselect node must be applied during query execution at vmstorage node. This will allow properly executing queries from the subset of vmselect nodes for reporting queries described above.

Commit 71bb9fc0d0 introduced a regression.
If labels are empty and relabeling is not configured, influx ingestion hanlder

message field to be both string and object type. Also added support of
not documented timestamp field
- added `-datadog.streamFields` and `-datadog.ignoreFields` flags to
configure default stream fields for datadog logs, where there's no
alternative option to pass extra headers and query args
- added ingest `max` and `min` values of data, which are ingested using
`datadogsketches` API, which is also actively used by serverless
extensions
- use default `.` separator instead of `_` for sketches metric names
until metrics are not sanitized
Historically some of VictoriaMetrics components were optimized for the low rate of memory allocations.
These are: vmagent, single-node VictoriaMetrics and vmstorage. These components benefit from the low
GOGC value, since this allow reducing their memory usage in steady state on typical workloads.
Other VictoriaMetrics components aren't optimized for the reduced rate of memory allocations.
This results in the increased CPU usage spent on garbage collection (GC) in these components,
since it must be triggered at higher rate. See https://tip.golang.org/doc/gc-guide#GOGC for details.
These components do not use too much memory, so it is OK increasing the GOGC for these components
from 30 to 100 - this won't affect the most users.
Keep GOGC to 30 only for vmagent, single-node VictoriaMetrics and vmstorage components.

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=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 service labels won't be attached when `role: tasks` is set.
Because the `addServicesLabels` function is shared by `role: tasks` and
`role: services`, and it will return nothing when `vip.Addr` is invalid
or empty.
In Prometheus, even if `vip.Addr` is empty, it attach common service
labels with [a standalone
function](f10c3454e9/discovery/moby/services.go (L129)),
which offers:
- `__meta_dockerswarm_service_id`: the id of the service.
- `__meta_dockerswarm_service_name`: the name of the service.
- `__meta_dockerswarm_service_mode`: the mode of the service.
- `__meta_dockerswarm_service_label_<labelname>`: each label of the
service, with any unsupported characters converted to an underscore.
This PR add a `addServicesLabelsForTask`, to replace the usage of
`addServicesLabels` when `role: tasks` is set. This function offers
common service labels listed above.

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.

Previously, during de-duplication staleness markers could be removed due to incorrect logic at
values equality check.
During the evaluation of read query vmselect deduplicates samples using dedupInterval option. It picks the highest value across all points with the same timestamp next to the border of dedupInterval. The issue is any comparison with NaN via <, > returns false. This means that the position of NaN in srcValues could affect the result.
This commit changes this logic with additional step, that explicitly checks for staleness marker for the following cases:
1. Deduplication on vmselect
2. Deduplication in vmstorage during merges
3. Deduplication in stream aggregation
check performed only for stale markers, because other NaNs are rejected on ingestion
by vmstorage or by stream aggregation.
Checking for stale markers in general slows down dedup speed by 3%:

* 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

This commit aligns behaviour of docker service discovery with Prometheus implementation.
It adds the following changes:
* introduce new config param `match_first_network` with default value of `true`. It uses the first network if the container has multiple networks
defined. It should help to avoid collecting duplicate targets error with multi network setups.
* add `networks` for the containers with linked network to the other containers with `network_mode: container:id` setting. It resolve an issue with attached containers aka `pods` in Kubernetes.

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.
Affected releases:
- 1.106.1
- v1.102.7
- v1.97.12

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.

Previously, if only `-dedup.minScrapeInterval` was set without
`downsampling.Period, function
getDownsamplingFilters returned empty result for
downsamplingPeriodFilters. Because it didn't take in
account globalDedup variable.
This commit adds fast path for this case and returns a single
downsampling filter with global interval value.
In addition, it adds the following changes:
* Removes global state modification at ParseDownsamplingPeriods
function. Which could lead to data races at vmselect
* simplifies logic of isDedupNeeded function. Since
donwsamplingPeriodsWithout filters is subset of
dowsamplingPeriodByFilters. There is no need for len check
* Improves tests by proper reset global state of downsampling

### Describe Your Changes
Many users are running k8s-stack in multiple kubernetes clusters and to
configure a proper routing in alertmanager it's required to support
`cluster` label in alerting rules. It's now implemented in helm-chart
hack scripts, but it's tricky part to define if cluster label should be
added or not, when functions has no `by` expression. Updated existing
alerts to provide later an ability to inject cluster label later
Also take into an account `storage.minFreeDiskSpaceBytes` in
`DiskRunsOutOfSpace` alerts

(cherry picked from commit fefa3e7936)
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
> // empty. (See RFC 7230, Section 5.3)
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.
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

Previously, for `^` aka pow function calls, VictoriaMetrics returned `1`
if left arg was Nan. For example, given query=`(hour()==2)^1` returns 1
for NaN produced by hour() == 2 function. It added additional non-exist
datapoints to the timeseries.

(cherry picked from commit bb399518db)
Previously, dedup was added as a downsampling rule with 0s offset to all downsmapling rules with filters. That enforced a metric name lookup even in cases it is not needed.
For example, the following configuration: `-dedup.minScrapeInterval=10s -downsampling.period={__name__=~"node.*"}:1h:1m` would be parsed as: `{__name__=~"node.*"}:1h:1m {}:0s:10s`
This commit changes this logic and treats dedup as a separate case. This allows to perform metric name lookups only in cases when timestamp of current partition can be eligible to use some of downsampling filters. Newer parts will not trigger metric name lookup and will apply deduplication directly.

After changes at commit 787b9cd. Minimal timestamps for extDB check was performed without context of the index search prefix.
It worked fine for Single node version, but for cluster version a different prefix was used for
metricID search requests. It may lead to incomplete results, if minimal missing timestamp was cached
for the tenant with different ingestion patterns.
Minimal reproducible case is:
- metrics were ingested for tenants 0 and 1
- at some point in time metrics ingestion for tenant 1 stopped
- index records have the following timestamps layout:
tenant 0: 1,2,3,4,5,6
tenant 1: 1,2,3,4
- after indexDB rotation, containsTimeRange lookups may produce
incorrect results:
time range request for tenant 1 - 5:6 caches 5 as min timestamp
request for the same or smaller time range for tenant 0 now returns
empty results.
Second case:
- requests for the tenant without metrics always updates atomic value with incorrect minimal time range for other tenants.
This commit replaces single atomic with map of search prefix keys. It should have slight performance overhead,
but work consistently for cluster version. minMissingTimestamp is cached by prefix search key, which included tenantID.
Since it will be only populated at runtime, it doesn't hold unused tenants for queries.

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

This commit properly handles this case and returns result according to
the graphite documentation:
`xFilesFactor follows the same semantics as in Whisper storage schemas. Setting it to 0 (the default) means that only a single value in the series needs to be non-null for it to be considered non-empty, setting it to 1 means that all values in the series must be non-null. A setting of 0.5 means that at least half the values in the series must be non-null.`

### 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
background merge accesses random entries, this fills up cache and does
not provide an actual improvement due to random access nature.

groups](https://docs.victoriametrics.com/cluster-victoriametrics/#vmstorage-groups-at-vmselect).
Previously, the following configuration would effectively be ignored:
```
/path/to/vmselect \
-replicationFactor=2 \
-storageNode=g1/host1,g1/host2,g1/host3 \
-storageNode=g2/host4,g2/host5,g2/host6 \
-storageNode=g3/host7,g3/host8,g3/host9
```
Changes from this PR will force default value for `replicationFactor`
flag to be set to `2` which is expected as the result of this
configuration.

This reduces the hard limit on duration for completing the test when
users run vmalert-tool on slow hosts.

Previously it was incorrectly used append for pre-allocated slice of labels.
This commit fixes slice append by allocating zero length slice with needed capacity.

After adding multitenant query feature at v1.104.0, searchQuery wasn't
properly unmarshalled at bottom vmselect in multi-level cluster setup.
It resulted into empty query responses.
This commit adds fallback to Unmarshal method of SearchQuery to fill
TenantTokens. It allows to properly execute search requests
at vmselect side.

### Describe Your Changes
- Added functionality to cancel running queries on the Explore Logs and
Query pages.
- The loader was changed from a spinner to a top bar within the block.
This still indicates loading, but solves the issue of the spinner
"flickering," especially during graph dragging.
