could automatically detect the needed lookbehind window depending on the time distance between real samples.
For example, rate(m[$__rate_interval]) is parsed and processed as rate(m) now.

### Describe Your Changes
> (currently in DRAFT) This dashboard and the docs may look differently
after recent review and the feedback received.
As requested by our customers, this PR introduces `anomaly score`-based
dashboard for `vmanomaly` to improve the visual experience and ease the
drill down debugging process for respective anomaly detection setups.
Accompanying guide (under `default` preset mode) is provided as well.
- [For additional
benefits](https://docs.victoriametrics.com/victoriametrics-datasource/#motivation),
the dashboard is based on [VictoriaMetrics
datasource](https://docs.victoriametrics.com/victoriametrics-datasource/)
rather than on `Prometheus` datasource
- Tested locally and on our https://play.victoriametrics.com/
`anomaly_score` data (tenant ID 0)
- To check the guide, build the docs locally (`vmdocs`, `make run
local`) and follow to the

Previously if rule group parameters were changed, alerting rules related metrics could be deleted due to bug at `utils/metrics` package.
This commit introduces `metrics.Set` per rule group. It holds group and alerting rules metrics. It properly unregister alerting rules metrics and addresses issue.
In addition:
- expose group metrics only once group is started - this helps to avoid
exposing metrics for groups which are created during YAML unmarshaling
and only used to update existing group.
- properly close rules which are discarded after updating existing rules
so that metrics are also correctly closed.
- detect file renames and properly recreate groups "moved" between files.

Examples:
- `top 5 x, y` is equivalent to `top 5 by (x, y)`
- `uniq foo, bar` is equivalent to `uniq by (foo, bar)`
- `unroll foo, bar` is equivalent to `unroll (foo, bar)`
Examples:
_time:>=2025-02-24Z selects logs with timestamps bigger or equal to 2025-02-24 UTC
_time:>1d selects logs with timestamps older than one day comparing to the current time
This simplifies writing queries with _time filters.

parsing errors. Escaping ']' would not strictly be necessary but is
REQUIRED by this specification to avoid syslog application
implementation errors. Each of these three characters MUST be
escaped as '\"', '\\', and '\]' respectively. The backslash is used
for control character escaping for consistency with its use for
escaping in other parts of the syslog message as well as in traditional syslog.

Use `rate_sum` instead of `total` output for the following reasons:
* `rate_sum` is far less sensitive for data delays than `total`, since
it represents the speed of change instead of absolute values.
* `rate_sum` remove need in using `rate` function for calculating final
results on query time.

### Describe Your Changes
By default, stream aggregation and deduplication stores a single state
per each aggregation output result.
The data for each aggregator is flushed independently once per
aggregation interval. But there's no guarantee that
incoming samples with timestamps close to the aggregation interval's end
will get into it. For example, when aggregating
with `interval: 1m` a data sample with timestamp 1739473078 (18:57:59)
can fall into aggregation round `18:58:00` or `18:59:00`.
It depends on network lag, load, clock synchronization, etc. In most
scenarios it doesn't impact aggregation or
deduplication results, which are consistent within margin of error. But
for metrics represented as a collection of series,
like
[histograms](https://docs.victoriametrics.com/keyconcepts/#histogram),
such inaccuracy leads to invalid aggregation results.
For this case, streaming aggregation and deduplication support mode with
aggregation windows for current and previous state. With this mode,
flush doesn't happen immediately but is shifted by a calculated samples
lag that improves correctness for delayed data.
Enabling of this mode has increased resource usage: memory usage is
expected to double as aggregation will store two states
instead of one. However, this significantly improves accuracy of
calculations. Aggregation windows can be enabled via
the following settings:
- `-streamAggr.enableWindows` at [single-node
VictoriaMetrics](https://docs.victoriametrics.com/single-server-victoriametrics/)
and [vmagent](https://docs.victoriametrics.com/vmagent/). At
[vmagent](https://docs.victoriametrics.com/vmagent/)
`-remoteWrite.streamAggr.enableWindows` flag can be specified
individually per each `-remoteWrite.url`.
If one of these flags is set, then all aggregators will be using fixed
windows. In conjunction with `-remoteWrite.streamAggr.dedupInterval` or
`-streamAggr.dedupInterval` fixed aggregation windows are enabled on
deduplicator as well.
- `enable_windows` option in [aggregation
config](https://docs.victoriametrics.com/stream-aggregation/#stream-aggregation-config).
It allows enabling aggregation windows for a specific aggregator.

### Describe Your Changes
This PR introduces several enhancements and optimizations for the Group
view:
1. **Disable hover effect:**
Add the option to disable the hover effect. This can help reduce CPU
load when viewing a large number of logs.
2. **Limit entries per Group:**
Add the ability to limit the number of records displayed per group. When
a limit is set, groups are rendered sequentially – the next group starts
only after the current group has finished. By default, there is no
limit.
3. **Display group info:**
Include the group number in the title along with the total count of
groups to improve clarity and navigation.
4. **Performance improvement:**
In addition to the features above, separate optimizations reduce CPU
load during hover interactions by approximately 5-10%.

This should improve query performance for logs with hundreds of fields (aka wide events).
Previously there was a high chance that the data for multiple log fields is stored in the same file.
This could result in query performance slowdown and/or increased disk read IO,
since the operating system could read unnecessary data for the fields, which aren't used in the query.
Now log fields are guaranteed to be stored in separate files until the number of fields exceeds 256.
After that multiple log fields start sharing files.
In this first step, content is moved from cloud docs root to a new
folder: get started. This one will allocate: overview, key features and
benefits, quickstart and guides and best practices.
### Changes Description
- In order to reuse content, the overview and README sections are
merged.
- A dummy Get started section is created, but needs further work.
- Next steps will also include reworking the quick start section and

all the rows from blockResult.
### Describe Your Changes
Allow disabling the per-day index using the `-disablePerDayIndex` flag.
This should significantly improve the ingestion rate and decrease the
disk space usage for the use cases that assume small or no churn rate.
See the docs added to `docs/README.md` for details.
Both improvements are due to no data written to the per-day index.

There are many subtle issues while ingesting logs from popular log shippers into VictoriaLogs via Loki JSON protocol.
For example, the common issue is that structured logs are ingested as a JSON string at _msg field.
This is not what most users expect - they expect that fields in structured logs are ingested as separate log fields.
It is better removing examples with configs for Loki JSON protocol, since other supported protocols work much better
without any issues. This should reduce the confusion level for new users, who try Loki protocol and hit its issues.
- Elasticsearch ( https://docs.victoriametrics.com/victorialogs/data-ingestion/#elasticsearch-bulk-api )
- JSON stream ( https://docs.victoriametrics.com/victorialogs/data-ingestion/#json-stream-api )
1. Use distinct code paths for blockResult.getValues() and blockResult.getValuesBucketed().
This should simplify debugging and maintenance of the resulting code.
2. Do not load column values if all the values in the block fit the same bucket.
Use blockResultColumn.minValue and blockResultColumn.maxValue for determining whether
column values must be loaded via blockResultColumn.getValuesEncoded().
This signiciantly improves performance for big buckets, which cover all the column
values in a block.
3. Properly calculate buckets for negative values.
4. Properly adjust weekly buckets by Monday.

- If the user has manually set a step value, it will remain unchanged
when switching views or changing the time range.
- The UI now explicitly indicates when the step is automatically
calculated.

There is an issue described in #8040 this should fix it
- The alerts slice is shared across multiple goroutines (since send() is
called concurrently).
- `alerts[:0]` creates a new slice header, but it still references the
same underlying array.
- Appending (append(alertsToSend, a)) modifies the underlying array,
which may also be used by another goroutine.
Solution: Use a separate slice copy for each goroutine.

Previously RFC3339 timestamps with sub-second precision could be incorrectly compared by lessString().
For example, 2025-01-20T10:20:30.1Z was incorrectly treated as smaller than 2025-01-20T10:20:30.09Z,
because the first timestamp has smaller decimal number after the last dot than the second timestamp.
Previosly the parsing of the input stream was stopped after the first parse error.
This isn't what most users expect when ingesting JSON lines in a stream where some JSON lines may be invalid.
Split unique values (groups) into shards according to the configured concurrency
during processing of the matching rows if the number of unique values exceeds the hardcoded threshold.
Previously this splitting was performed unconditionally at the merge stage when merging independently
calculated per-CPU states into a single state. It is faster to perform the split during rows processing
if the number of unique values is big.
This gives up to 30% perfromance improvements when these pipes are applied to big number of unique values (groups).
The number of worker shards per each pipe processor is created during query initialization.
This number equals to the `options(concurrency=N)` if this option is set or to the number of available CPU cores.
This means that all the pipes must adhere the given concurrency when passing data blocks
to the next pipe.

The bug has been introduced in 0214aa328e
vmauth uses 'lib/httpserver' for serving HTTP requests. This server
unconditionally defines built-in routes (such as '/metrics',
'/health', etc). It makes impossible to proxy `HTTP` requests to backends with the same routes.
Since vmauth's httpserver matches built-in route and return local
response.
This commit adds new flag `httpInternalListenAddr` with
default empty value. Which removes internal API routes from public
router and exposes it at separate http server.
For example given configuration disables private routes at `0.0.0.0:8427` address and serves it at `0.0.0.0:8426`:
`./bin/vmauth --auth.config=config.yaml --httpListenAddr=:8427 --httpInternalListenAddr=127.0.0.1:8426`

This commit improves integration with third-party solutions who rely on non-root
endpoints (i.e. MinIO) when the vmselect path has been specified in the
configured Prometheus URL like:
`http://vmselect.:8481/select/0/prometheus`
Comparable change has been done before
(b885a3b6e9), however only takes care of
the root path. This means endpoints `-/healthy` and `-/ready` are still
not available on full vmselect Prometheus paths, resulting in
unsupported path requests.
This change makes these endpoints available on the full paths like:
`/select/0/prometheus/-/healthy` and `/select/0/prometheus/-/ready`,
thus achieving full Prometheus compatibility for external dependencies.

### Describe Your Changes
The cardinality limiter in this case does not receive the actual
metricID but some other value found in r.TSID.MetricID and is not
initialized. Depending on the system and/or go runtime implementation,
this value can be 0 or some garbage value (which shouldn't have too wide
a range). Thus, there basically no limit for inserted metricIDs.

At v1.107.0 release with commit 21a7f06fc4beeb6ad32b9f7fd88704ed33674905 was introduced regression.
It prevents kafka producer client from graceful shutdown. This change also removed kafka message headers.
This commit properly closes client.
It also addresses the following issues:
* properly add headers to kafka message
* add url_id to the exported metrics, which prevents possible metrics clash if multiple remote write targets have
the same url and topic name.

The update also returns an error if metric name is specified twice in

For example, `foo{__name__="bar"}` is not allowed anymore. It would
successfully parse before
this change, but it won't satisfy the search filter any way. So it had
no sense in supporting this. This is why some test cases were removed.

At this time `bufferedwriter` [silently ignores connection close
errors](78eaa056c0/lib/bufferedwriter/bufferedwriter.go (L67)).
It may be very convenient in some situations (to not log such
unimportant errors), but it's too implicit and unsafe for the others.
For example, if you close [export
API](https://docs.victoriametrics.com/#how-to-export-time-series) client
connection in the middle of communication, VictoriaMetrics won't notice
it and will start to hog CPU by exporting all the data into nowhere
until it process all of them. If you'll make a few retries, it will be
effectively a DoS on the server.
This commit replaces this implicit error suppressing with explicit error
handling which fixes the issue with export API.

This should reduce the time needed for opening the storage with retentions exceeding a few months.
While at at, limit the concurrency of opening partitions in parallel to the number of available CPU cores,
since higher concurrency may increase RAM usage and CPU usage without performance improvements
if opening a single partition is CPU-bound task.

### Describe Your Changes
- Added the `fields_limit` parameter for the `hits` query to limit the
number of returned fields. This reduces the response size and decreases
memory usage.
#### Legend Menu:
A context menu has been added for legend items, which includes:
1. Metric name
2. **Copy _stream name** - copies the full stream name in the format
`{field1="value1", ..., fieldN="valueN"}`.
3. **Add _stream to filter** - adds the full stream value to the current
filter:
`_stream: {field1="value1", ..., fieldN="valueN"} AND (old_expr)`.
4. **Exclude _stream from filter** - excludes the stream from the
current filter:
`(NOT _stream: {field1="value1", ..., fieldN="valueN"}) AND (old_expr)`.
5. List of fields with options:
- Copy as `field: "value"`.
- Add to filter: `field: "value" AND (old_expr)`.
- Exclude from filter: `-field: "value" AND (old_expr)`.
6. Total number of hits for the stream.

The purpose of extra filters ( https://docs.victoriametrics.com/victorialogs/querying/#extra-filters )
is to limit the subset of logs, which can be queried. For example, it is expected that all the queries
with `extra_filters={tenant=123}` can access only logs, which contain `123` value for the `tenant` field.
Previously this wasn't the case, since the provided extra filters weren't applied to subqueries.
For example, the following query could be used to select all the logs outside `tenant=123`, for any `extra_filters` arg:
* | union({tenant!=123})
This commit fixes this by propagating extra filters to all the subqueries.
While at it, this commit also properly propagates [start, end] time range filter from HTTP querying APIs
into all the subqueries, since this is what most users expect. This behaviour can be overriden on per-subquery
basis with the `options(ignore_global_time_filter=true)` option - see https://docs.victoriametrics.com/victorialogs/logsql/#query-options
Also properly apply apply optimizations across all the subqueries. Previously the optimizations at Query.optimize()
function were applied only to the top-level query.
Previously, NewChild elements of querytracer could be referenced by concurrent
storageNode goroutines. After earlier return ( if search.skipSlowReplicas is set), it is
possible, that tracer objects could be still in-use by concurrent workers.
It may cause panics and data races. Most probable case is when parent tracer is finished, but children
still could write data to itself via Donef() method. It triggers read-write data race at trace
formatting.
This commit adds a new methods to the querytracer package, that allows to
create children not referenced by parent and add it to the parent later.
Orphaned child must be registered at the parent, when goroutine returns. It's done synchronously by the single caller via finishQueryTracer call.
If child didn't finished work and reference for it is used by concurrent goroutine, new child must be created instead with
context message.
It prevents panics and possible data races.

This is done via 'options(concurrency=N)' prefix for the query.
For example, the following query is executed on at most 4 CPU cores:
options(concurrency=4) _time:1d | count_uniq(user_id)
This allows reducing RAM and CPU usage at the cost of longer query execution times,
since by default every query is executed in parallel on all the available CPU cores.
