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

Simon Pasquier	cccd542891	*: avoid missed Alertmanager targets (#6455 ) This change makes sure that nearly-identical Alertmanager configurations aren't merged together. The config's identifier was the MD5 hash of the configuration serialized to JSON but because `relabel.Regexp` has no public field and doesn't implement the JSON.Marshaler interface, it was always serialized to "{}". In practice, the identifier can be based on the index of the configuration in the list. Signed-off-by: Simon Pasquier <spasquie@redhat.com>	5 years ago

Chris Marchbanks	a6a55c433c	Improve desired shards calculation (#5763 ) The desired shards calculation now properly keeps track of the rate of pending samples, and uses the previously unused integralAccumulator to adjust for missing information in the desired shards calculation. Also, configure more capacity for each shard. The default 10 capacity causes shards to block on each other while sending remote requests. Default to a 500 sample capacity and explain in the documentation that having more capacity will help throughput. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	5 years ago

Callum Styan	6f69e31398	Tail the TSDB WAL for remote_write This change switches the remote_write API to use the TSDB WAL. This should reduce memory usage and prevent sample loss when the remote end point is down. We use the new LiveReader from TSDB to tail WAL segments. Logic for finding the tracking segment is included in this PR. The WAL is tailed once for each remote_write endpoint specified. Reading from the segment is based on a ticker rather than relying on fsnotify write events, which were found to be complicated and unreliable in early prototypes. Enqueuing a sample for sending via remote_write can now block, to provide back pressure. Queues are still required to acheive parallelism and batching. We have updated the queue config based on new defaults for queue capacity and pending samples values - much smaller values are now possible. The remote_write resharding code has been updated to prevent deadlocks, and extra tests have been added for these cases. As part of this change, we attempt to guarantee that samples are not lost; however this initial version doesn't guarantee this across Prometheus restarts or non-retryable errors from the remote end (eg 400s). This changes also includes the following optimisations: - only marshal the proto request once, not once per retry - maintain a single copy of the labels for given series to reduce GC pressure Other minor tweaks: - only reshard if we've also successfully sent recently - add pending samples, latest sent timestamp, WAL events processed metrics Co-authored-by: Chris Marchbanks <csmarchbanks.com> (initial prototype) Co-authored-by: Tom Wilkie <tom.wilkie@gmail.com> (sharding changes) Signed-off-by: Callum Styan <callumstyan@gmail.com>	6 years ago
