(cherry picked from commit c896bf340d)
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.

VictoriaLogs allows logs without `_msg` field or `_msg` field is empty.
This lead to incorrect search result. See:

This pull request search for non-empty `_msg` field before log entry is
added to `LogRows`.
New counter `vl_rows_dropped_total{reason="msg_not_exist"}` is
introduced.

Previously the original timestamp was used in the copied query, so _time:duration filters
were applied to the original time range: (timestamp-duration ... timestamp]. This resulted

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.

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.

Recent versions of `docker build` started generating the InvalidDefaultArgInFrom warning if Dockerfile contains
an ARG without default value. While this warning doesn't affect building Docker packages via `make package-*` commands,
it is better suppressing the warning, so it doesn't clutter `make package-*` output with the noise,
which can hide real issues in the future.
…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

(cherry picked from commit d523015f27)
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:
```
pkg: github.com/VictoriaMetrics/VictoriaMetrics/app/vmalert/datasource
BenchmarkParsePrometheusResponse/Instant_std+fastjson-10 1760 668959 ns/op 280147 B/op 5781 allocs/op
MBs allocated at heap: 493.078392
mallocs: 18655472
BenchmarkParsePrometheusResponse/Instant_fastjson-10 6109 198258 ns/op 172839 B/op 5548 allocs/op
MBs allocated at heap: 1056.384464
mallocs: 34457184
BenchmarkParsePrometheusResponse/Instant_std-10 1287 950987 ns/op 451677 B/op 9619 allocs/op
MBs allocated at heap: 580.802976
mallocs: 13351636
```
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
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.

`Storage.AddRows()` returns an error only in one case: when
`Storage.updatePerDateData()` fails to unmarshal a `metricNameRaw`. But
the same error is treated as a warning when it happens inside
`Storage.add()` or returned by `Storage.prefillNextIndexDB()`.
This commit fixes this inconsistency by treating the error returned by
`Storage.updatePerDateData()` as a warning as well. As a result
`Storage.add()` does not need a return value anymore and so doesn't
`Storage.AddRows()`.
Additionally, this commit adds a unit test that checks all cases that
result in a row not being added to the storage.

This reverts commit 4d66e042e3.
Reasons for revert:
- The commit makes unrelated invalid changes to docs/CHANGELOG.md
- The changes at app/vmauth/main.go are too complex. It is better splitting them into two parts:
- pooling readTrackingBody struct for reducing pressure on GC
- avoiding to use readTrackingBody when -maxRequestBodySizeToRetry command-line flag is set to 0
Let's make this in the follow-up commits!

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6533
- Move the test for SRV discovery into a separate function. This allows verifying round-robin discovery across SRV records.
- Restore the original netutil.Resolver after the test finishes, so it doesn't interfere with other tests.
- Move the description of the bugfix into the correct place at docs/CHANGELOG.md - it should be placed under v1.102.0-rc2
instead of v1.102.0-rc1.
- Remove unneeded code in URLPrefix.sanitizeAndInitialize(), since it is expected this function is called only once
for finishing URLPrefix initializiation. In this case URLPrefix.nextDiscoveryDeadline and URLPrefix.n are equal to 0
according to https://pkg.go.dev/sync/atomic#Uint64
- Properly fix the bug at URLPrefix.discoverBackendAddrsIfNeeded() - it is expected that hostToAddrs map uses
the original hostname keys, including 'srv+' prefix, so it shouldn't be removed when looping over up.busOriginal.
Instead, the 'srv+' prefix must be removed from the hostname only locally before passing the hostname to netutil.Resolver.LookupSRV.

- Rename GetStatDialFunc to NewStatDialFunc, since it returns new function with every call
- NewStatDialFunc isn't related to http in any way, so it must be moved from lib/httputils to lib/netutil
- Simplify the implementation of NewStatDialFunc by removing sync.Map from there.
- Use netutil.NewStatDialFunc at app/vmauth and lib/promscrape/discoveryutils
- Use gauge instead of counter type for *_conns metric

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6299
- Move the remaining code responsible for stream aggregation initialization from remotewrite.go to streamaggr.go .
This improves code maintainability a bit.
- Properly shut down streamaggr.Aggregators initialized inside remotewrite.CheckStreamAggrConfigs().
This prevents from potential resource leaks.
- Use separate functions for initializing and reloading of global stream aggregation and per-remoteWrite.url stream aggregation.
This makes the code easier to read and maintain. This also fixes INFO and ERROR logs emitted by these functions.
- Add an ability to specify `name` option in every stream aggregation config. This option is used as `name` label
in metrics exposed by stream aggregation at /metrics page. This simplifies investigation of the exposed metrics.
- Add `path` label additionally to `name`, `url` and `position` labels at metrics exposed by streaming aggregation.
This label should simplify investigation of the exposed metrics.
- Remove `match` and `group` labels from metrics exposed by streaming aggregation, since they have little practical applicability:
it is hard to use these labels in query filters and aggregation functions.
- Rename the metric `vm_streamaggr_flushed_samples_total` to less misleading `vm_streamaggr_output_samples_total` .
This metric shows the number of samples generated by the corresponding streaming aggregation rule.
This metric has been added in the commit 861852f262 .
See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6462
- Remove the metric `vm_streamaggr_stale_samples_total`, since it is unclear how it can be used in practice.
This metric has been added in the commit 861852f262 .
See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6462
- Remove Alias and aggrID fields from streamaggr.Options struct, since these fields aren't related to optional params,
which could modify the behaviour of the constructed streaming aggregator.
Convert the Alias field to regular argument passed to LoadFromFile() function, since this argument is mandatory.
- Pass Options arg to LoadFromFile() function by reference, since this structure is quite big.
This also allows passing nil instead of Options when default options are enough.
- Add `name`, `path`, `url` and `position` labels to `vm_streamaggr_dedup_state_size_bytes` and `vm_streamaggr_dedup_state_items_count` metrics,
so they have consistent set of labels comparing to the rest of streaming aggregation metrics.
- Convert aggregator.aggrStates field type from `map[string]aggrState` to `[]aggrOutput`, where `aggrOutput` contains the corresponding
`aggrState` plus all the related metrics (currently only `vm_streamaggr_output_samples_total` metric is exposed with the corresponding
`output` label per each configured output function). This simplifies and speeds up the code responsible for updating per-output
metrics. This is a follow-up for the commit 2eb1bc4f81 .
See https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6604
- Added missing urls to docs ( https://docs.victoriametrics.com/stream-aggregation/ ) in error messages. These urls help users
figuring out why VictoriaMetrics or vmagent generates the corresponding error messages. The urls were removed for unknown reason
in the commit 2eb1bc4f81 .
- Fix incorrect update for `vm_streamaggr_output_samples_total` metric in flushCtx.appendSeriesWithExtraLabel() function.
While at it, reduce memory usage by limiting the maximum number of samples per flush to 10K.

The old link was changed globally to the new link in the commit f4b1cbfef0 .
Unfortunately, old links are still posted in new commits :(
This is a follow-up for 680b8c25c8 .
While at it, remove duplicate 'len(*remoteWriteURLs) > 0' check in the remotewrite.Init() functions,
since this check is already made at the beginning of the function.
