Bryan Boreham	1ed94142fc	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 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. This pull request adds a simple PuppetDB service discovery, which will enable more use cases than the upstream sd. Signed-off-by: Julien Pivotto <roidelapluie@inuits.eu>	3 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.

Julien Pivotto	5bce801a09	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.

Alexey Shumkin	73ddf603af	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. Signed-off-by: Alexey Shumkin <Alex.Crezoff@gmail.com>	4 years ago
