Julien Pivotto	8920024323	Add PuppetDB service discovery We have been Puppet user for 10 years and we are users of https://github.com/camptocamp/prometheus-puppetdb-sd However, that file_sd implementation contains business logic and assumptions around e.g. the modules which you are using.

TJ Hoplock	7baf084092	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.

Julien Duchesne	8855c2e626	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 Signed-off-by: Julien Duchesne <julien.duchesne@grafana.com> * Change metric name + set unset value to -1 Signed-off-by: Julien Duchesne <julien.duchesne@grafana.com> * Only check the last value of the clean start alert Signed-off-by: Julien Duchesne <julien.duchesne@grafana.com> * Fix test + nit Signed-off-by: Julien Duchesne <julien.duchesne@grafana.com>	4 years ago

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 Signed-off-by: Tom Wilkie <tom.wilkie@gmail.com>	4 years ago
