  • [CHANGE] --alertmanager.configs.auto-slack-root flag was dropped as auto Slack root is not supported anymore. #1597
  • [ENHANCEMENT] Upgraded Prometheus to 2.12.0 and Alertmanager to 0.19.0. #1597

0.2.0 / 2019-09-05

This release has several exciting features, the most notable of them being setting -ingester.spread-flushes to potentially reduce your storage space by upto 50%.

  • [CHANGE] Flags changed due to changes upstream in Prometheus Alertmanager #929:
    • alertmanager.mesh.listen-address is now cluster.listen-address
    • alertmanager.mesh.peer.host and alertmanager.mesh.peer.service can be replaced by cluster.peer
    • alertmanager.mesh.hardware-address, alertmanager.mesh.nickname, alertmanager.mesh.password, and alertmanager.mesh.peer.refresh-interval all disappear.
  • [CHANGE] --claim-on-rollout flag deprecated; feature is now always on #1566
  • [CHANGE] Retention period must now be a multiple of periodic table duration #1564
  • [CHANGE] The value for the name label for the chunks memcache in all cortex_cache_ metrics is now chunksmemcache (before it was memcache) #1569
  • [FEATURE] Makes the ingester flush each timeseries at a specific point in the max-chunk-age cycle with -ingester.spread-flushes. This means multiple replicas of a chunk are very likely to contain the same contents which cuts chunk storage space by up to 66%. #1578
  • [FEATURE] Make minimum number of chunk samples configurable per user #1620
  • [FEATURE] Honor HTTPS for custom S3 URLs #1603
  • [FEATURE] You can now point the query-frontend at a normal Prometheus for parallelisation and caching #1441
  • [FEATURE] You can now specify http_config on alert receivers #929
  • [FEATURE] Add option to use jump hashing to load balance requests to memcached #1554
  • [FEATURE] Add status page for HA tracker to distributors #1546
  • [FEATURE] The distributor ring page is now easier to read with alternate rows grayed out #1621

0.1.0 / 2019-08-07

  • [CHANGE] HA Tracker flags were renamed to provide more clarity #1465
    • distributor.accept-ha-labels is now distributor.ha-tracker.enable
    • distributor.accept-ha-samples is now distributor.ha-tracker.enable-for-all-users
    • ha-tracker.replica is now distributor.ha-tracker.replica
    • ha-tracker.cluster is now distributor.ha-tracker.cluster
  • [FEATURE] You can specify "heap ballast" to reduce Go GC Churn #1489
  • [BUGFIX] HA Tracker no longer always makes a request to Consul/Etcd when a request is not from the active replica #1516
  • [BUGFIX] Queries are now correctly cancelled by the query-frontend #1508
