optimize Linode SD by polling for event changes during refresh (#8980)
* optimize Linode SD by polling for event changes during refresh

Most accounts are fairly "static", in the sense that they're not cycling
through instances constantly. So rather than do a full refresh every
interval and potentially make several behind-the-scenes paginated API
calls, this will now poll the `/account/events/` endpoint every minute
with a list of events that we care about. If a matching event is found,
we then do a full refresh.

Add prometheus_tsdb_clean_start metric (#8824)
Add cleanup of the lockfile when the db is cleanly closed

The metric describes the status of the lockfile on startup
0: Already existed
1: Did not exist
-1: Disabled

Therefore, if the min value over time of this metric is 0, that means that executions have exited uncleanly
We can then use that metric to have a much lower threshold on the crashlooping alert:

If the metric exists and it has been zero, two restarts is enough to trigger the alarm
If it does not exist (old prom version for example), the current five restarts threshold remains

Damien Grisonnet b50f9c1c84
Add label scrape limits (#8777)
* scrape: add label limits per scrape

Add three new limits to the scrape configuration to provide some
mechanism to defend against unbound number of labels and excessive
label lengths. If any of these limits are broken by a sample from a
scrape, the whole scrape will fail. For all of these configuration
options, a zero value means no limit.

The `label_limit` configuration will provide a mechanism to bound the
number of labels per-scrape of a certain sample to a user defined limit.
This limit will be tested against the sample labels plus the discovery
labels, but it will exclude the __name__ from the count since it is a
mandatory Prometheus label to which applying constraints isn't
meaningful.

The `label_name_length_limit` and `label_value_length_limit` will
prevent having labels of excessive lengths. These limits also skip the
__name__ label for the same reasons as the `label_limit` option and will
also make the scrape fail if any sample has a label name/value length
that exceed the predefined limits.

Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com>

* scrape: add metrics and alert to label limits

Add three gauge, one for each label limit to easily access the
limit set by a certain scrape target.
Also add a counter to count the number of targets that exceeded the
label limits and thus were dropped. This is useful for the
`PrometheusLabelLimitHit` alert that will notify the users that scraping
some targets failed because they had samples exceeding the label limits
defined in the scrape configuration.

Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com>

* scrape: apply label limits to __name__ label

Apply limits to the __name__ label that was previously skipped and
truncate the label names and values in the error messages as they can be
very very long.

Signed-off-by: Damien Grisonnet <dgrisonn@redhat.com>

* scrape: remove label limits gauges and refactor

Remove `prometheus_target_scrape_pool_label_limit`,
`prometheus_target_scrape_pool_label_name_length_limit`, and
`prometheus_target_scrape_pool_label_value_length_limit` as they are not
really useful since we don't have the information on the labels in it.

Tom Wilkie d479151f1f Various enhancements and refactorings for remote write receiver:
- Remove unrelated changes
- Refactor code out of the API module - that is already getting pretty crowded.
- Don't track reference for AddFast in remote write.  This has the potential to consume unlimited server-side memory if a malicious client pushes a different label set for every series.  For now, its easier and safer to always use the 'slow' path.
- Return 400 on out of order samples.
- Use remote.DecodeWriteRequest in the remote write adapters.
- Put this behing the 'remote-write-server' feature flag
- Add some (very) basic docs.
- Used named return & add test for commit error propagation
