This is a follow-up for f60c08a7bd
Changes:
- Make sure all the urls related to NewRelic protocol start from /newrelic . Previously some urls were started from /api/v1/newrelic
- Remove /api/v1 part from NewRelic urls, since it has no sense
- Remove automatic transformation from CamelCase to snake_case for NewRelic labels and metric names,
since it may complicate the transition from NewRelic to VictoriaMetrics. Preserve all the metric names and label names,
so users could query metrics and labels by the same names which are used in NewRelic.
The automatic transformation from CamelCase to snake_case can be added later as a special action for relabeling rules if needed.
- Properly update per-tenant data ingestion stats at app/vmagent/newrelic/request_handler.go . Previously it was always zero.
- Fix NewRelic urls in vmagent when multitenant data ingestion is enabled. Previously they were mistakenly started from `/`.
- Document NewRelic data ingestion url at docs/Cluster-VictoriaMetrics.md
- Remove superflouos memory allocations at lib/protoparser/newrelic
- Improve tests at lib/protoparser/newrelic/*

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4712
- Make more clear the docs at docs/enterprise.md, so readers could figure out faster
on how to obtain enterprise key and how to pass it to VictoriaMetrics Enterprise components.
- Fix examples at docs/enterprise.md, which were referring to non-existing `-license-file` command-line flag.
The `-licenseFile` command-line flag must be used instead.
- Improve the description of `-license*` command-line flags, so users could understand
faster how to use them.
- Improve the warning message, which is emitted when the deprecated -eula command-line flag is passed,
so the user could figure out how to switch faster to -license* command-line flags.
- Disallow running VictoriaMetrics components with both -license and -licenseFile command-line flags.
- Disallow running VictoriaMetrics components when -licensFile points to an empty file.
- Consistently use the phrase "This flag is available only in Enterprise binaries" across
all the enterprise-specific command-line flags.
- Remove unneeded level of indirection for `noLicenseMessage` and `expiredMessage` string contants
in order to improve code readability and maintainability.
- Remove unneded `return` statements after `logger.Fatalf()` calls, since these calls exit the app and never return.
- Make sure that the info log message about successful license verification is emitted
when the license is verified successfully. Previously the error message could be logged
when the license payload is invalid or if it misses some required features.
- Reduce vertical space usage, so more information is available on the screen without the need to scroll.
- Show information for lines with higher values at the top of the legend under the graph.
This should simplify graph analysis when it contains many lines.
reduce lock contention for heavy aggregation requests
previously lock contetion may happen on machine with big number of CPU due to enabled string interning. sync.Map was a choke point for all aggregation requests.
Now instead of interning, new string is created. It may increase CPU and memory usage for some cases.

* vmalert: add `query_time_alignment` for rule group
1. add `eval_alignment` attribute for group which by default is true. So group rule query stamp will be aligned with interval and propagated to ALERT metrics and the messages for alertmanager;
2. deprecate `datasource.queryTimeAlignment` flag.
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5049
Strip sensitive information such as auth headers or passwords from datasource, remote-read,
remote-write or notifier URLs in log messages or UI. This behavior is by default and is controlled via
`-datasource.showURL`, `-remoteRead.showURL`, `remoteWrite.showURL` or `-notifier.showURL` cmd-line flags.
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5044
* lib/promscrape: make concurrency control optional
Before, `-maxConcurrentInserts` was limiting all calls to `promscrape.Parse`
function: during ingestion and scraping. This behavior is incorrect.
Cmd-line flag `-maxConcurrentInserts` should have effect onl on ingestion.
Since both pipelines use the same `promscrape.Parse` function, we extend it
to make concurrency limiter optional. So caller can decide whether concurrency
should be limited or not.
This commit makes c53b5788b4
obsolete.

- Compare the actual free disk space to the value provided via -storage.minFreeDiskSpaceBytes
directly inside the Storage.IsReadOnly(). This should work fast in most cases.
This simplifies the logic at lib/storage.
- Do not take into account -storage.minFreeDiskSpaceBytes during background merges, since
it results in uncontrolled growth of small parts when the free disk space approaches -storage.minFreeDiskSpaceBytes.
The background merge logic uses another mechanism for determining whether there is enough
disk space for the merge - it reserves the needed disk space before the merge
and releases it after the merge. This prevents from out of disk space errors during background merge.
- Properly handle corner cases for flushing in-memory data to disk when the storage
enters read-only mode. This is better than losing the in-memory data.
- Return back Storage.MustAddRows() instead of Storage.AddRows(),
since the only case when AddRows() can return error is when the storage is in read-only mode.
This case must be handled by the caller by calling Storage.IsReadOnly()
before adding rows to the storage.
This simplifies the code a bit, since the caller of Storage.MustAddRows() shouldn't handle
errors returned by Storage.AddRows().
- Properly store parsed logs to Storage if parts of the request contain invalid log lines.
Previously the parsed logs could be lost in this case.

- Switch from summary to histogram for vl_http_request_duration_seconds metric.
This allows calculating request duration quantiles across multiple hosts
via histogram_quantile(0.99, sum(vl_http_request_duration_seconds_bucket) by (vmrange)).
- Take into account only successfully processed data ingestion requests
when updating vl_http_request_duration_seconds histogram.
Failed requests are ignored, since they may significantly skew measurements.

Adding limit on ingestion allows to avoid issues like this one https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4762

Add -remoteWrite.shardByURL command-line flag, which instructs vmagent to spread evenly
outgoing time series data among the configured remote storage systems specified via -remoteWrite.url .

- Use a byte slice instead of a map for tracking indexes for matching series.
This improves performance, since access by slice index is faster than access by map key.
- Re-use the byte slice for tracking indexes for matching series.
This removes unnecessary memory allocations and improves stream aggregation performance a bit.
- Add an ability to return to the previous behvaiour by specifying -remoteWrite.streamAggr.dropInput command-line flag.
In this case all the input samples are dropped when stream aggregation is enabled.
- Backport the new stream aggregation behaviour from vmagent to single-node VictoriaMetrics when -streamAggr.config

- Improve docs
- Hide `debug relabeling` column when -promscrape.dropOriginalLabels command-line flag is set
- Inline the code from the added template functions, since the code is harder to follow
with the template functions, especially when these functions have misleading names.
Also, these functions are used only in one place, e.g. they do not reduce the amounts of code.
- Hide `click to show original labels` title at `labels` column when original labels aren't available.
- Show the reason on whey original labels aren't available at /service-discovery page.

- Parse protobuf if Content-Type isn't set to `application/json` - this behavior is documented at https://grafana.com/docs/loki/latest/api/#push-log-entries-to-loki
- Properly handle gzip'ped JSON requests. The `gzip` header must be read from `Content-Encoding` instead of `Content-Type` header
- Properly flush all the parsed logs with the explicit call to vlstorage.MustAddRows() at the end of query handler
- Check JSON field types more strictly.
- Allow parsing Loki timestamp as floating-point number. Such a timestamp can be generated by some clients,
which store timestamps in float64 instead of int64.
- Optimize parsing of Loki labels in Prometheus text exposition format.
- Simplify tests.
- Remove lib/slicesutil, since there are no more users for it.
- Update docs with missing info and fix various typos. For example, it should be enough to have `instance` and `job` labels
as stream fields in most Loki setups.
- Allow empty of missing timestamps in the ingested logs.
The current timestamp at VictoriaLogs side is then used for the ingested logs.
This simplifies debugging and testing of the provided HTTP-based data ingestion APIs.
The remaining MAJOR issue, which needs to be addressed: victoria-logs binary size increased from 13MB to 22MB
after adding support for Loki data ingestion protocol at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4482 .
This is because of shitty protobuf dependencies. They must be replaced with another protobuf implementation
similar to the one used at lib/prompb or lib/prompbmarshal .
Loki uses default labels format without "or" operator. This format can't create a list of LabelFilters, so only first set of LabelFilters should be used.

The `a op b keep_metric_names` is ambigouos to `a op (b keep_metric_names)` when `b` is a transform or rollup function.
For example, `a + rate(b) keep_metric_names`. So it is better to use more clear syntax: `(a op b) keep_metric_names`
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3710
* metricsql: add support of using keep_metric_names for binary operations
This should help to avoid confusion with queries like one in the issue #3710.

Previously all the newly ingested time series were registered in global `MetricName -> TSID` index.
This index was used during data ingestion for locating the TSID (internal series id)
for the given canonical metric name (the canonical metric name consists of metric name plus all its labels sorted by label names).
The `MetricName -> TSID` index is stored on disk in order to make sure that the data
isn't lost on VictoriaMetrics restart or unclean shutdown.
The lookup in this index is relatively slow, since VictoriaMetrics needs to read the corresponding
data block from disk, unpack it, put the unpacked block into `indexdb/dataBlocks` cache,
and then search for the given `MetricName -> TSID` entry there. So VictoriaMetrics
uses in-memory cache for speeding up the lookup for active time series.
This cache is named `storage/tsid`. If this cache capacity is enough for all the currently ingested
active time series, then VictoriaMetrics works fast, since it doesn't need to read the data from disk.
VictoriaMetrics starts reading data from `MetricName -> TSID` on-disk index in the following cases:
- If `storage/tsid` cache capacity isn't enough for active time series.
Then just increase available memory for VictoriaMetrics or reduce the number of active time series
ingested into VictoriaMetrics.
- If new time series is ingested into VictoriaMetrics. In this case it cannot find
the needed entry in the `storage/tsid` cache, so it needs to consult on-disk `MetricName -> TSID` index,
since it doesn't know that the index has no the corresponding entry too.
This is a typical event under high churn rate, when old time series are constantly substituted
with new time series.
Reading the data from `MetricName -> TSID` index is slow, so inserts, which lead to reading this index,
are counted as slow inserts, and they can be monitored via `vm_slow_row_inserts_total` metric exposed by VictoriaMetrics.
Prior to this commit the `MetricName -> TSID` index was global, e.g. it contained entries sorted by `MetricName`
for all the time series ever ingested into VictoriaMetrics during the configured -retentionPeriod.
This index can become very large under high churn rate and long retention. VictoriaMetrics
caches data from this index in `indexdb/dataBlocks` in-memory cache for speeding up index lookups.
The `indexdb/dataBlocks` cache may occupy significant share of available memory for storing
recently accessed blocks at `MetricName -> TSID` index when searching for newly ingested time series.
This commit switches from global `MetricName -> TSID` index to per-day index. This allows significantly
reducing the amounts of data, which needs to be cached in `indexdb/dataBlocks`, since now VictoriaMetrics
consults only the index for the current day when new time series is ingested into it.
The downside of this change is increased indexdb size on disk for workloads without high churn rate,
e.g. with static time series, which do no change over time, since now VictoriaMetrics needs to store
identical `MetricName -> TSID` entries for static time series for every day.
This change removes an optimization for reducing CPU and disk IO spikes at indexdb rotation,
since it didn't work correctly - see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401 .
At the same time the change fixes the issue, which could result in lost access to time series,
which stop receving new samples during the first hour after indexdb rotation - see https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2698
The issue with the increased CPU and disk IO usage during indexdb rotation will be addressed
in a separate commit according to https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1401#issuecomment-1553488685

It could happen for low evaluation intervals and irregular
delays during execution that evaluation time would get
a negative offset. This could result into cumulative
discrepancy between the actual time and evaluation time for rules.

NB: In Openshift these containers are marked as vulnerabilities
because of these CVEs.
Error message will be present for any auth error, but message claims an error is about OAuth2 configuration which is confusing.

By default, vmalert will make multiple retry attempts with exponential delay.
The total time spent during retry attempts shouldn't exceed `-remoteWrite.retryMaxTime` (default is 30s).
When retry time is exceeded vmalert drops the data dedicated for `-remoteWrite.url`.
Before, vmalert dropped data after 5 retry attempts with 1s delay between attempts (not configurable).
See `-remoteWrite.retryMinInterval` and `-remoteWrite.retryMaxTime` cmd-line flags.

This reverts commit c19048dc13.
Reason for revert: it has been appeared that the net/http.ResponseWriter is already buffered,
so there in no need in double bufferring
This simplifies routing at auth proxies such as vmauth to vlselect component,
which serves VMUI - just route all the requests, which start with /select/, to vlselect.
