vmalert: introduce additional HTTP URL params per-group configuration (#1892) 
* vmalert: introduce additional HTTP URL params per-group configuration

The new group field `params` allows to configure custom HTTP URL params
per each group. These params will be applied to every request before
executing rule's expression. Hot config reload is also supported.

Field `extra_filter_labels` was deprecated in favour of `params` field.
vmalert will print deprecation log message if config file contains
the deprecated field.

`params` fields are supported by both Prometheus and Graphite datasource types.

* vmalert: provide more examples for `params` field

Signed-off-by: hagen1778 <roman@victoriametrics.com>

* vmalert: set higher priority for `params` setting

If there would be a conflict between URL params set in `datasource.url` flag
and params in group definition the latter will have higher priority.

app: use relative paths instead of absolute paths for the supported http handlers on the main page 
This allows hiding VictoriaMetrics components behind proxies, which serve pages at different path prefixes

vmalert: continue to print errors for bad config during hot reload (#1871) 
Previously, vmalert would print an err message and set vmalert_config_last_reload_successful=0
only once during a hot reload of a bad config. Such behaviour may result into non noticed
event of a bad config reload attempt

Now, it continues to print error messages and keep vmalert_config_last_reload_successful state
until successful attempt will be made or config state will be rolled back to prev state.

vmalert: make notifier.Addr optional (#1870) 
For a long time notifier.Addr flag was required. The assumption was that vmalert will
be always used for alerting. However, practice shows that some users need only
recording rules. In this case, requirement of notifier.Addr is ambigious.

The change verifies if loaded config contains recording or alerting rules and
if there are corresponding flags set. This is true for initial config load
and hot reload.

vmalert: correctly calculate alert ID including extra labels (#1734) 
Previously, ID for alert entity was generated without alertname or groupname.
This led to collision, when multiple alerting rules within the same group
producing same labelsets. E.g. expr: `sum(metric1) by (job) > 0` and
expr: `sum(metric2) by (job) > 0` could result into same labelset `job: "job"`.

The issue affects only UI and Web API parts of vmalert, because alert ID is used
only for displaying and finding active alerts. It does not affect state restore
procedure, since this label was added right before pushing to remote storage.

The change now adds all extra labels right after receiving response from the datasource.
And removes adding extra labels before pushing to remote storage.

Additionally, change introduces a new flag `Restored` which will be displayed in UI
for alerts which have been restored from remote storage on restart.

lib/promscrape: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice 
This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode
at the cost of the increased memory usage, since now the potentially big response is kept
in the lastScrape byte slice per each scrapeWork.

In practice the memory usage increase shouldn't be big, since the response size
is usually much smaller than the parsed metrics from this response after the relabeling,
which usually adds a big pile of target-specific labels per each metric.

while `http.Transport.MaxIdleConns` is inherited from DefaultTransport and is equal to `100`.
The fix adjusts `http.Transport.MaxIdleConns` value if it is lower than `http.Transport.MaxIdleConnsPerHost`.

app/vmselect: quantile func compatiblity with Prometheus (#1646) 
* app/vmselect: `quantile` func compatiblity with Prometheus

The `quantile` func was previously calculated by https://github.com/valyala/histogram
package. The result of such calculation was always the closest real value to
requested quantile. While in Prometheus implementation interpolation is used.
Such difference may result into discrepancy in output between Prometheus and
VictoriaMetrics.

This commit adds a Prometheus-like `quantile` function. It also used by other
functions which depend on it, such as `quantiles`, `quantile_over_time`, `median` etc.

75c3514c5c lib/promrelabel: add keep_metrics and drop_metrics actions to relabeling rules 
These actions simlify metrics filtering. For example,

- action: keep_metrics
  regex: 'foo|bar|baz'

would leave only metrics with `foo`, `bar` and `baz` names, while the rest of metrics will be deleted.

The commit also makes possible to split long regexps into multiple lines. For example, the following config is equivalent to the config above:

- action: keep_metrics
  regex:
  - foo
  - bar
  - baz

1cf4f5a715 Vmalert extra params (#1587) 
* vmalert: allow extra GET params in datasource package

ExtraParams will be added as GET params to every HTTP request made by datasource.
The `roundDigits` param, for example, was substituted by corresponding extra param.

* vmalert: add nocache=1 param for replay process

The `nocache=1` param is VictoriaMetrics specific parameter which prevents it
from caching and boundaries aligning for queries. We set it to avoid cache
pollution in `replay` mode and also to avoid unnecessary time range boundaries
alignment.

* vmalert: mention nocache=1 in replay description

* vmalert: remove `vmalert_execution_duration_seconds` metric

The summary for `vmalert_execution_duration_seconds` metric gives no additional
value comparing to `vmalert_iteration_duration_seconds` metric.

* vmalert: update config reload success metric properly

Previously, if there was unsuccessfull attempt to reload config and then
rollback to previous version - the metric remained set to 0.

* vmalert: add Grafana dashboard to overview application metrics

* docker: include vmalert target into list for scraping

* vmalert: extend notifier metrics with addr label

The change adds an `addr` label to metrics for alerts_sent and alerts_send_errors
to identify which exact address is having issues.
The according change was made to vmalert dashboard.

* vmalert: update documentation and docker environment for vmalert's dashboard

Mention Grafana's dashboard in vmalert's README in a new section #Monitoring.

Update docker-compose env to automatically add vmalert's dashboard.
Update docker-compose README with additional info about services.

1ccb77904b vmselect: update vm_request_duration_seconds value when request fails (#1537) 
Before, metric `vm_request_duration_seconds` was update only on successful

request may be not accounted in the metric and won't be visible on dashboards.

d5ba8248cc vmalert: expose new metrics for tracking number of produced samples during last evaluation (#1518) 
* vmalert: expose new metrics for tracking number of produced samples during last evaluation

Two new metrics were added to track the number of samples produced during the last evaluation:
* vmalert_recording_rules_last_evaluation_samples
* vmalert_alerting_rules_last_evaluation_samples

The gauge type is used to remain consistent with Prometheus metric
`prometheus_rule_group_last_evaluation_samples` which is on the group level.
However, the counter type was considered as well.

Two metrics instead of one are used to make it easier to separate recording and
alerting rules. It is likely, number of samples produced by recording rules is
more important so people will refer to it more frequently.

The expected usage of the new metric is the following:
```
   - alert: RecordingRuleReturnsEmptyResults
        expr: sum(vmalert_recording_rules_last_evaluation_samples) by(recording) < 1
        annotations:
          summary: Recording rule {{$labels.recording}} returns empty results.
            Please verify expression correctness.
```

b55677e93d Vmalert: adjust time param for datasource queries according to evaluationInterval (#1257) 
* Simplify arguments list for fn `queryDataSource` to improve readbility

* vmalert: adjust `time` param according to rule evaluation interval

With this change, vmalert will start to use rule's evaluation interval
for truncating the `time` param. This is mostly needed to produce consistent
time series with timestamps unaffected by vmalert start time. Now, timestamp
becomes predictable.
Additionally, adjustment is similar to what Grafana does for plotting range graphs.
Hence, recording rule series and recording rule expression plotted in grafana
suppose to become similar in most of cases.

which means rule's expression will be executed at some moment in the past.
To avoid such situations, vmalert now will use returned timestamp instead of `lastExecTime`.

ff3711eea2 docs: update docs ordering and formatting (#1192) 
The major change is adding `sort` directive to docs. For those docs which are copied
from internal packages `sort` is added via makefile command. For the rest it is added
manually since they're updated manually as well.

The rest of changes is connected with markdown formatting. For example, changing headers
in some files (`##` => `#`) makes navigation on .github.io to look better. This especially
useful for `changelog` docs.

Table of contents for `vmctl` is dropped, since we already have it autogenerated on .github.io.

No link changes expected. The corresponding PR to `cluster` branch will be made in follow-up PR.

so validation can pass successfully. Later, during the rule execution, stub will be replaced

9f578e389c vmalert: add function "query", "first" and "value" to alert templates functions (#960) 
The commit adds a support for template function `query`,
`first` and `value`. The function `query` executes
a MetricsQL query for active alerts. In vmalert we
update templates on every evaluation for active alerts
to keep them up to date. With `query` func it may become
a perf issue since it will fire a query on every execution.
We should keep it in mind for now.

4fd2b6cd16 vmalert: explicitly set extra labels to alert entities (#886) 
The previous implementation treated extra labels (global and rule labels) as
separate label set to returned time series labels. Hence, time series always contained
only original labels and alert ID was generated from sorted labels key-values.
Extra labels didn't affect the generated ID and were applied on the following actions:
- templating for Summary and Annotations;
- persisting state via remote write;
- restoring state via remote read.

Such behaviour caused difficulties on restore procedure because extra labels had to be dropped
before checking the alert ID, but that not always worked. Consider the case when expression
returns the following time series `up{job="foo"}` and rule has extra label `job=bar`.
This would mean that restored alert ID will be always different to the real time series because
of collision.

To solve the situation extra labels are now always applied beforehand and `vmalert` doesn't
store original labels anymore. However, this could result into a new error situation.
Consider the case when expression returns two time series `up{job="foo"}` and `up{job="baz"}`,
while rule has extra label `job=bar`. In such case, applying extra labels will result into
two identical time series and `vmalert` will return error:
 `result contains metrics with the same labelset after applying rule labels`

16e0bb496e vmalert: update groups on config reload only if changes detected (#759) 
On config reload event `vmalert` reloads configuration for every group. While
it works for simple configurations, the more complex and heavy installations may
suffer from frequent config reloads.
The change introduces the `checksum` field for every group and is set to md5 hash
of yaml configuration. The checksum will change if on any change to group
definition like rules order or annotation change. Comparing the `checksum` field
on config reload event helps to detect if group should be updated.
The groups update is now done concurrently, so reload duration will be limited by
the slowest group now.

Partially solves #691 by improving config reload speed.

Expose `vm_timestamps_blocks_merged_total` and `vm_timestamps_bytes_saved_total` metrics for monitoring
the effectiveness of timestamp blocks merging.

80a9dc79fe changed vmalert behaviour (#738) 
* VMAlert start with empty rules dir

There are some applications (operator for instance), that generates alerts configuration at runtime
and vmalert must start correctly without rules to support this behaviour.
Later application will add rules files and send SIGHUP to vmalert,
which will trigger reading rules files and start rules exectuion.

Removing rules files with SIGHUP signal must stop rules execution and
vmalert will wait for new rules.

* imports sorted

* added test cases for empty rules, removed blank line

* fixed imports conflict

* updated tests

78afc61896 app/vmalert: extend metrics set exported by vmalert #573 (#654) 
* app/vmalert: extend metrics set exported by `vmalert` #573

New metrics were added to improve observability:
+ vmalert_alerts_pending{alertname, group} - number of pending alerts per group
per alert;
+ vmalert_alerts_acitve{alertname, group} - number of active alerts per group
per alert;
+ vmalert_alerts_error{alertname, group} - is 1 if alertname ended up with error
during prev execution, is 0 if no errors happened;
+ vmalert_recording_rules_error{recording, group} - is 1 if recording rule
 ended up with error during prev execution, is 0 if no errors happened;
* vmalert_iteration_total{group, file} - now contains group and file name labels.
This should improve control over specific groups;
* vmalert_iteration_duration_seconds{group, file} - now contains group and file name labels. This should improve control over specific groups;

Some collisions for alerts and recording rules are possible, because neither
group name nor alert/recording rule name are unique for compatibility reasons.

Commit contains list of TODOs for Unregistering metrics since groups and rules
are ephemeral and could be removed without application restart. In order to
unlock Unregistering feature corresponding PR was filed - https://github.com/VictoriaMetrics/metrics/pull/13

* app/vmalert: extend metrics set exported by `vmalert` #573

The changes are following:
* add an ID label to rules metrics, since `name` collisions within one group is
a common case - see the k8s example alerts;
* supports metrics unregistering on rule updates. Consider the case when one rule
was added or removed from the group, or the whole group was added or removed.

The change depends on https://github.com/VictoriaMetrics/metrics/pull/16
where race condition for Unregister method was fixed.
