stream aggregation: fix possible duplicated aggregation results (#7118)
When ingesting samples with the same labels(duplicated samples or
samples with the same labels after `by` or `without` options). They
could register different entries for the same labelset in
LabelsCompressor.
For example, both index 99 and 100 can be assigned to label `foo=1` in
two concurrent pushes. Then due to differing label indexes in encoded
keys, the samples will appear as distinct in aggrState, resulting in
duplicated results after decompressing the label indexes.

fbde238cdc/lib/streamaggr/streamaggr.go (L933)

In this pull request, since we need to store `idxToLabel` first to
ensure the idx can be searched after `lc.labelToIdxStore`,
the `lc.idxToLabel` still could contain a duplicated entries
[100]="foo=1". But given the low likelihood of this issue and the size
of idxToLabel, it should be fine.

fscore: rollback trailing space trim (#7106)
Previous commit 201fd6de1e removed
trailing space trim from data read from file. But common practice is to
remove such trailing space. And it leaded to the authorization errors
for the major group of users.

In first place, this change must help to mitigate an issue with
kubernetes. When authorization information was read from Secret content.
Changes to the operator was made to mitigate such problem at commit
1cf64358c8

We could introduce later optional flag for VictoriaMetrics to disable
trim space behavior.

app/vmalert: bump default values for sending data to remoteWrite.url (#7084)
* `remoteWrite.maxQueueSize` from `100_000` to `1_000_000`, this should
improve resiliency of recording rules that produce many series;
* `remoteWrite.maxBatchSize` from `1_000` to `10_000`, this should be
more efficient to send from netwroking perspective;
* `remoteWrite.concurrency` from `1` to `4`, this should imrpove speed
of sending the generated series.

The new settings should improve remote write performance of vmalert with
default settings.

deployment: add panel and alerts for displying go scheduler latency (#7078)
The panel and alerting rule should help to understand whether VM
component doesn't have enough CPU resources or gets throttled. The alert
is applicable for all VM components.
The panel was added to vmalert, vmagent, vmsingle, vm clusert and
victorialogs dashes.

-------------------

This alerting rule should have help us identify resource shortage for
sandbox vmagent - see [this
link](https://play.victoriametrics.com/select/accounting/1/6a716b0f-38bc-4856-90ce-448fd713e3fe/prometheus/graph/#/?g0.range_input=23d13h25m25s424ms&g0.end_input=2024-09-23T14%3A11%3A00&g0.relative_time=none&g0.tab=0&g0.expr=histogram_quantile%280.99%2C+sum%28rate%28go_sched_latencies_seconds_bucket%7Bjob%3D%22vmagent-monitoring-vmagent%22%7D%5B5m%5D%29%29+by+%28le%2C+job%2C+instance%29%29+%3E+0.1)
for example. We weren't aware of resource shortage, because VM metrics
assumed this vmagent had 1vCPU while in fact its limit was 0.2vCPU.

app/vmselect/promql: consistently replace NaN data points with non-NaN values for range_first and range_last functions
It is expected that range_first and range_last functions return non-nan const value across all the points
if the original series contains at least a single non-NaN value. Previously this rule was violated for NaN data points
in the original series. This could confuse users.

While at it, add tests for series with NaN values across all the range_* and running_* functions, in order to maintain
consistent handling of NaN values across these functions.

metricID->TSID index records. IndexDB metrics fix exposed misleading
metric for such missing records.

* This commit adds check for metricID->TSID missing index records. And
delete missing metricID entry if it hit 60 second deadline.

vmalert: do not send message to alertmanager when alert has no label … (#6823)
…pair

`alert_relabel_configs` in [notifier
config](https://docs.victoriametrics.com/vmalert/#notifier-configuration-file)
can drop alert labels when used to filter different tenant alert message
to different notifier.
alertmanager would report error like `msg="Failed to validate alerts"
err="at least one label pair required"` in this case, but the rest of
the alerts inside one request would still be valid in alertmanager, so
it's not severe.

lib/discovery/azure: fix host check in next link in Azure SD (#6915)
Previous bugfix at 49f63b2 only partially fixed pagination host validation error.

 Before this fix it was:
```
unexpected nextLink host \"management.azure.com\", expecting \"https://management.azure.com\"
```

Now we only check the `Host` without schema. 

However, when Azure respond `nextLink` in `Host:Port` format, the
`nextLink` check will fail:
```
unexpected nextLink host \"management.azure.com:443\", expecting \"management.azure.com\"
```

This pull request further relaxes the checks by only checking the
`Hostname`.

   - json encoding is impossible to use with language SDK.

* splits metrics and logs structures at lib/protoparser/opentelemetry/pb package.

* adds docs with examples for opentelemetry logs.

stream aggregation: perform deduplication for all received data when … (#6711)
…specifying `-streamAggr.dedupInterval` or
`-remoteWrite.streamAggr.dedupInterval` command-line flag

[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
config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config).
3. To deduplicate all the received data while having `streamAggr.config`
for some metrics
--- no way for a single vmagent now, need to set up two level vmagents

This PR implements case3.

docs: fix broken links to prev changelogs
The prev links like `/changelog_2021/`
stopped working after 9dc8d1debd
because these files now require specifying the parent `changelog` in the path, like `/changelog/changelog_2021/`.

This fix adds an alias for an old link.

lib/storage: properly add previous indexDB metrics (#6890)
Previously, some extIndexDB metrics were not registered. It resulted
into missing metrics, if metric value was added to the extIndexDB. It's
a usual case for search requests at both indexes.

 Current commit updates all metrics from extIndexDB according to the
current IndexDB. It must fix such cases

lib/storage: properly handle maxMetrics limit at metricID search
`TL;DR` This PR improves the metric IDs search in IndexDB:

- Avoid seaching for metric IDs twice when `maxMetrics` limit is
exceeded
- Use correct error type for indicating that the `maxMetrics` limit is
exceded
- Simplify the logic of deciding between per-day and global index search

A unit test has been added to ensure that this refactoring does not
break anything.

---

Function calls before the fix:

```
idb.searchMetricIDs
    |__ is.searchMetricIDs
        |__ is.searchMetricIDsInternal
            |__ is.updateMetricIDsForTagFilters
                |__ is.tryUpdatingMetricIDsForDateRange
                |                       |
                |__ is.getMetricIDsForDateAndFilters
```

- `searchMetricIDsInternal` searches metric IDs for each filter set. It
maintains a metric ID set variable which is updated every time the
`updateMetricIDsForTagFilters` function is called. After each successful
call, the function checks the length of the updated metric ID set and if
it is greater than `maxMetrics`, the function returns `too many
timeseries` error.
- `updateMetricIDsForTagFilters` uses either per-day or global index to
search metric IDs for the given filter set. The decision of which index
to use is made is made within the `tryUpdatingMetricIDsForDateRange`
function and if it returns `fallback to global search` error then the
function uses global index by calling `getMetricIDsForDateAndFilters`
with zero date.
- `tryUpdatingMetricIDsForDateRange` first checks if the given time
range is larger than 40 days and if so returns `fallback to global
search` error. Otherwise it proceeds to searching for metric IDs within
that time range by calling `getMetricIDsForDateAndFilters` for each
date.
- `getMetricIDsForDateAndFilters` searches for metric IDs for the given
date and returns `fallback to global search` error if the number of
found metric IDs is greater than `maxMetrics`.

Problems with this solution:

1. The `fallback to global search` error returned by
`getMetricIDsForDateAndFilters` in case when maxMetrics is exceeded is
misleading.
2. If `tryUpdatingMetricIDsForDateRange` proceeds to date range search
and returns `fallback to global search` error (because
`getMetricIDsForDateAndFilters` returns it) then this will trigger
global search in `updateMetricIDsForTagFilters`. However the global
search uses the same maxMetrics value which means this search is
destined to fail too. I.e. the same search is performed twice and fails
twice.
3. `too many timeseries` error is already handled in
`searchMetricIDsInternal` and therefore handing this error in
`updateMetricIDsForTagFilters` is redundant
4. updateMetricIDsForTagFilters is a better place to make a decision on
whether to use per-day or global index.

Solution:

1.  Use a dedicated error for `too many timeseries` case
2. Handle `too many timeseries` error in  `searchMetricIDsInternal` only
3. Move the per-day or global search decision from
`tryUpdatingMetricIDsForDateRange` to `updateMetricIDsForTagFilters` and
remove `fallback to global search` error.

lib/storage: properly register index records with RegisterMetricNames
Once the timeseries is in tsidCache, new entries won't be created in
per-day index because the RegisterMetricNames() code does consider
different dates for the same timeseries. So this case has been added.

The same bug exists for AddRows() but it is not manifested because the
index entries are finally created in updatePerDateData().

RegisterMetricNames also updated to increase the newTimeseriesCreated
counter because it actually creates new time series in index.

A unit tests has been added that check all possible data patterns
(different metric names and dates) and code branches in both
RegisterMetricNames and AddRows. The total number of new unit tests is
around 100 which increaded the running time of storage tests by 50%.
