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.	8 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.	8 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.

Fuente, Pablo Andres	902fafb8e7	Fixing tests for Windows Fixing the config/config_test, the discovery/file/file_test and the promql/promql_test tests for Windows. For most of the tests, the fix involved correct handling of path separators. In the case of the promql tests, the issue was related to the removal of the temporal directories used by the storage. The issue is that the RemoveAll() call returns an error when it tries to remove a directory which is not empty, which seems to be true due to some kind of process that is still running after closing the storage. To fix it I added some retries to the remove of the temporal directories. Adding tags file from Universal Ctags to .gitignore	9 years ago

Brian Brazil	30448286c7	Add sample_limit to scrape config. This imposes a hard limit on the number of samples ingested from the target. This is counted after metric relabelling, to allow dropping of problemtic metrics. This is intended as a very blunt tool to prevent overload due to misbehaving targets that suddenly jump in sample count (e.g. adding a label containing email addresses). Add metric to track how often this happens. Fixes #2137	9 years ago
