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

Philippe Laflamme	2aba238f31	Use common HTTPClientConfig for marathon_sd configuration (#4009 ) This adds support for basic authentication which closes #3090 The support for specifying the client timeout was removed as discussed in https://github.com/prometheus/common/pull/123. Marathon was the only sd mechanism doing this and configuring the timeout is done through `Context`. DC/OS uses a custom `Authorization` header for authenticating. This adds 2 new configuration properties to reflect this. Existing configuration files that use the bearer token will no longer work. More work is required to make this backwards compatible.	7 years ago

Corentin Chary	60dafd425c	consul: improve consul service discovery (#3814 ) * consul: improve consul service discovery Related to #3711 - Add the ability to filter by tag and node-meta in an efficient way (`/catalog/services` allow filtering by node-meta, and returns a `map[string]string` or `service`->`tags`). Tags and nore-meta are also used in `/catalog/service` requests. - Do not require a call to the catalog if services are specified by name. This is important because on large cluster `/catalog/services` changes all the time. - Add `allow_stale` configuration option to do stale reads. Non-stale reads can be costly, even more when you are doing them to a remote datacenter with 10k+ targets over WAN (which is common for federation). - Add `refresh_interval` to minimize the strain on the catalog and on the service endpoint. This is needed because of that kind of behavior from consul: https://github.com/hashicorp/consul/issues/3712 and because a catalog on a large cluster would basically change all the time. No need to discover targets in 1sec if we scrape them every minute. - Added plenty of unit tests.

Also sends and additional 1Mbps of traffic to consul. Being a little bit smarter about this reduces the overhead quite a lot. Limiting the number of `/catalog/services` queries per second almost removes the overhead of service discovery. * consul: tweak `refresh_interval` behavior `refresh_interval` now does what is advertised in the documentation, there won't be more that one update per `refresh_interval`. It now defaults to 30s (which was also the current waitTime in the consul query). This also make sure we don't wait another 30s if we already waited 29s in the blocking call by substracting the number of elapsed seconds. Hopefully this will do what people expect it does and will be safer for existing consul infrastructures.	7 years ago

Thibault Chataigner	bf4a279a91	Remote storage reads based on oldest timestamp in primary storage (#3129 ) Currently all read queries are simply pushed to remote read clients. This is fine, except for remote storage for wich it unefficient and make query slower even if remote read is unnecessary. So we need instead to compare the oldest timestamp in primary/local storage with the query range lower boundary. If the oldest timestamp is older than the mint parameter, then there is no need for remote read. This is an optionnal behavior per remote read client.
