Tariq Ibrahim	8fdfa8abea	refine error handling in prometheus (#5388 ) i) Uses the more idiomatic Wrap and Wrapf methods for creating nested errors. ii) Fixes some incorrect usages of fmt.Errorf where the error messages don't have any formatting directives. iii) Does away with the use of fmt package for errors in favour of pkg/errors Signed-off-by: tariqibrahim <tariq181290@gmail.com>	6 years ago

xjewer	0d1a69353e	scrape: Add global jitter for HA server (#5181 ) * scrape: Add global jitter for HA server Covers issue in https://github.com/prometheus/prometheus/pull/4926#issuecomment-449039848 where the HA setup become a problem for targets unable to be scraped simultaneously. The new jitter per server relies on the hostname and external labels which necessarily to be uniq. As before, scrape offset will be calculated with regard the absolute time, so even restart/reload doesn't change scrape time per scrape target + prometheus instance. Use fqdn if possible, otherwise fall back to the hostname. It adds extra random seed to calculate server hash to be distinguish on machines with the same hostname, but different DC.

Wei Guo	996fd958ac	fix deadlock in scrape manager (#4894 ) Scrape manager will fall in deadlock when we reload configs frequently.	6 years ago
Krasi Georgiev	47a673c3a0	process scrape loops reloading in parallel (#4526 ) The scrape manage receiver's channel now just saves the target sets and another backgorund runner updates the scrape loops every 5 seconds. This is so that the scrape manager doesn't block the receiving channel when it does the long background reloading of the scrape loops. Active and dropped targets are now saved in each scrape pool instead of the scrape manager. This is mainly to avoid races when getting the targets via the web api. When reloading the scrape loops now happens in parallel to speed up the final disared state and this also speeds up the prometheus's shutting down. Also updated some funcs signatures in the web package for consistency. Signed-off-by: Krasi Georgiev <kgeorgie@redhat.com>	6 years ago
Fabian Reinartz	ad4c33c1ff	scrape,api: provide per-target metric metadata This adds a per-target cache of scraped metadata. The metadata is only available for the lifecycle of the attached target. An API endpoint allows to select metadata by metric name and a label selection of targets. Signed-off-by: Fabian Reinartz <freinartz@google.com>	7 years ago
