Aliaksandr Valialkin	71ea4935de	lib/promscrape: add -promscrape.suppressDuplicateScrapeTargetErrors command-line flag in order to suppress duplicate scrape target errors ... Show also original labels for duplicate targets in error message in order to simplify debugging the issue.

Roman Khavronenko	4cdffb04a4	vmalert: update groups on config reload only if changes detected (#759) ... On config reload event `vmalert` reloads configuration for every group. While it works for simple configurations, the more complex and heavy installations may suffer from frequent config reloads. The change introduces the `checksum` field for every group and is set to md5 hash of yaml configuration. The checksum will change if on any change to group definition like rules order or annotation change. Comparing the `checksum` field on config reload event helps to detect if group should be updated. The groups update is now done concurrently, so reload duration will be limited by the slowest group now. Partially solves #691 by improving config reload speed.	2020-09-11 20:14:30 +01:00

Nikolay Khramchikhin	764b3d4fda	changed vmalert behaviour (#738) ... * VMAlert start with empty rules dir There are some applications (operator for instance), that generates alerts configuration at runtime and vmalert must start correctly without rules to support this behaviour. Later application will add rules files and send SIGHUP to vmalert, which will trigger reading rules files and start rules exectuion. Removing rules files with SIGHUP signal must stop rules execution and vmalert will wait for new rules. * imports sorted * added test cases for empty rules, removed blank line * fixed imports conflict * updated tests	2020-09-03 11:04:42 +03:00
