Jesus Vazquez c1b669bf9b
Add out-of-order sample support to the TSDB (#11075)
* Introduce out-of-order TSDB support

This implementation is based on this design doc:
https://docs.google.com/document/d/1Kppm7qL9C-BJB1j6yb6-9ObG3AbdZnFUBYPNNWwDBYM/edit?usp=sharing

This commit adds support to accept out-of-order ("OOO") sample into the TSDB
up to a configurable time allowance. If OOO is enabled, overlapping querying
are automatically enabled.

Most of the additions have been borrowed from
https://github.com/grafana/mimir-prometheus/

Allow escaping a dollar sign when expanding external labels (#10129)
* Allow escaping a dollar sign when expanding external labels

There is currently no mechanism to natively escape a dollar sign
in the os.Expand function. As a workaround, this commit modifies
the external label expansion logic to treat a double dollar ($$)
as a mechanism for escaping the dollar character.

remote-write: slow down retries to avoid DDOS (#9634)
* remote-write: slow down retries to avoid DDOS

Increase the default max retry time from 100ms to 5 seconds.

Remote write calls are retried after a recoverable error such as the
back-end returning 500. Prometheus waits the minimum time and retries,
then doubles the wait on each subsequent retry until the maximum is
reached.

If some data is still getting through, remote-write will also increase
shards, and the default maximum is 200. 200 shards sending every 100ms
is 20 calls per second, to a back-end that is already in trouble.

5 seconds was chosen to match the default BatchSendDeadline: if we can
afford to wait that long for no response, then we can wait the same time
to retry. We will reach 5 seconds after 9 successive failures.

Julien Pivotto 8920024323 Add PuppetDB service discovery
We have been Puppet user for 10 years and we are users of

However, that file_sd implementation contains business logic and
assumptions around e.g. the modules which you are using.

This pull request adds a simple PuppetDB service discovery, which will
enable more use cases than the upstream sd.

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

* 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.

Rename discovery/dockerswarm to discovery/moby (#8691)
This makes it clear that the dockerswarm package does more than docker
swarm, but does also docker.

I have picked moby as it is the upstream name: https://mobyproject.org/

There is no user-facing change, except in the case of a bad
configuration. Previously, a user who would have a bad docker sd config
would see an error like:

> field xx not found in type dockerswarm.plain

Now that error would be turned into:

> field xx not found in type moby.plain

While not perfect, it should at not be confusing between docker and
dockerswarm.

discovery/kubernetes: Fix valid label selector causing config error
Label selector can be
"set-based"(https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#set-based-requirement)
but such a selector causes Prometheus start failure with the "unexpected
error: parsing YAML file ...: invalid selector: 'foo in (bar,baz)';
can't understand 'baz)'"-like error.

This is caused by the `fields.ParseSelector(string)` function that
simply splits an expression as a CSV-list, so a comma confuses such a
parsing method and lead to the error.

Use `labels.Parse(string)` to use a valid lexer to parse a selector
expression.

Closes #8284.

The config's identifier was the MD5 hash of the configuration serialized
