Chris Marchbanks	0685eb5395	Refactor testutil.NewStorage into a new package This avoids a circular dependency between the testutil and storage packages. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	5 years ago
Brian Brazil	b98e818876	Add scrape_series_added per-scrape metric. (#5546 ) This is an estimate of churn, with series being added to the cache being considered churn. This will have both false positives (e.g. series appearing and disappearing) and false negatives (e.g. series hit sample_limit, but still created in head block), but should be generally useful as-is. Relevant docs live in another repo. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago
Simon Pasquier	c1682adb2f	Bump prometheus/common to v0.3.0 (#5344 ) * Reload certificates from disk automatically This change bumps github.com/prometheus/common to include https://github.com/prometheus/common/pull/173 Signed-off-by: Simon Pasquier <spasquie@redhat.com> * scrape: close idle connections on reload/stop Signed-off-by: Simon Pasquier <spasquie@redhat.com> * use v0.3.0 tag Signed-off-by: Simon Pasquier <spasquie@redhat.com>	6 years ago
Brian Brazil	f7184978f4	Protect against memory exhaustion when scraping. Now that we're not losing the scrape cache across failed scrape, a scrape that continually failed but had varying series or metadata (e.g. timestamps in metric names, plus hitting smaple_limit) would grow the cache indefinitely. Add some code to catch that, and flush the cache anyway. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago
Brian Brazil	dd3073616c	Don't lose the scrape cache on a failed scrape. This avoids CPU usage increasing when the target comes back. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	6 years ago
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.

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.
