master / unreleased

1.6.0 / 2021-01-05

  • [CHANGE] Add default present for ruler limits on all 'user' types. #221, #222
  • [CHANGE] Enabled sharding for the blocks storage compactor. #218
  • [CHANGE] Removed -blocks-storage.bucket-store.index-cache.postings-compression-enabled CLI flag because always enabled in Cortex 1.6. #224
  • [ENHANCEMENT] Introduce a resources dashboard for the Alertmanager. #219
  • [ENHANCEMENT] Improves query visibility in the Ruler Dashboard for both chunks and blocks storage. #226
  • [ENHANCEMENT] Add query-scheduler to dashboards. Add alert for queries stuck in scheduler. #228
  • [ENHANCEMENT] Improved blocks storage observability: #224 #230
    • Cortex / Writes: added current number of tenants in the cluster
    • Cortex / Writes Resources: added ingester disk read/writes/utilisation
    • Cortex / Reads Resources: added store-gateway disk read/writes/utilisation
    • Cortex / Queries: added "Lazy loaded index-headers" and "Index-header lazy load duration"
    • Cortex / Compactor: added "Tenants compaction progress", "Average blocks / tenant" and "Tenants with largest number of blocks"
    • Alerts: added "CortexMemoryMapAreasTooHigh"
  • [ENHANCEMENT] Fine-tuned gRPC keepalive pings to work nicely with Cortex default settings. #233 #234
    • -server.grpc.keepalive.min-time-between-pings=10s
    • -server.grpc.keepalive.ping-without-stream-allowed:true
  • [BUGFIX] Fixed workingset memory panel while rolling out a StatefulSet. #229
  • [BUGFIX] Fixed CortexRequestErrors alert to not include ready route. #230

1.5.0 / 2020-11-12

  • [CHANGE] Add the default preset 'extra_small_user' and reference it in the CLI flags. This will raise the limits of the 'small_user' preset to the defaults for ingester.max-samples-per-query and ingester.max-series-per-query. #200
  • [CHANGE] Removed the config option $._config.ingester.statefulset_replicas which was used only when running Cortex chunks storage with WAL enabled. To configure the number of ingester replicas you should now use the following: #210 
    ingester_statefulset+:
    statefulSet.mixin.spec.withReplicas(6),
  • [CHANGE] The compactor statefulset is now configured with the Parallel pod management policy, in order to scale up quickly. #214
  • [ENHANCEMENT] Add the Ruler to the read resources dashboard #205
  • [ENHANCEMENT] Read dashboards now use cortex_querier_request_duration_seconds metrics to allow for accurate dashboards when deploying Cortex as a single-binary. #199
  • [ENHANCEMENT] Improved Ruler dashboard. Includes information about notifications, reads/writes, and per user per rule group evaluation. #197, #205
  • [ENHANCEMENT] Add new CortexCompactorRunFailed alert when compactor run fails. #206
  • [ENHANCEMENT] Add flusher-job-blocks.libsonnet with support for flushing blocks disks. #187
  • [ENHANCEMENT] Add more alerts on failure conditions for ingesters when running the blocks storage. #208
  • [FEATURE] Latency recording rules for the metriccortex_querier_request_duration_seconds are now part of a cortex_querier_api rule group. #199
  • [FEATURE] Add overrides-exporter as optional deployment to expose configured runtime overrides and presets. #198
  • [FEATURE] Add a dashboard for the alertmanager. #207
  • [BUGFIX] Added ingester-blocks to ingester's job label matcher, in order to correctly get metrics when migrating a Cortex cluster from chunks to blocks. #203

1.4.0 / 2020-10-02

  • [CHANGE] Lower the default overrides configs for ingestion and create a new overrides user out of the previous config #183
  • [CHANGE] The project is now licensed with Apache-2.0 license. #169
  • [CHANGE] Add overrides config to tsdb store-gateway. #167
  • [CHANGE] Ingesters now default to running as StatefulSet with WAL enabled. It is controlled by the config $._config.ingester_deployment_without_wal which is false by default. Setting the config to true will yield the old behaviour (stateless Deployment without WAL enabled). #72
  • [CHANGE] We now allow queries that are 32 days long. For example, rate(metric[32d]). Before it was 31d. #173
  • [CHANGE] Renamed container_name and pod_name label names to container and pod respectively. This is required in order to comply with cAdvisor metrics changes shipped with Kubernetes 1.16. #179
  • [CHANGE] Removed the experimental prefix from blocks storage CLI flags. #179
  • [CHANGE] Rename flags store-gateway.replication-factor and store-gateway.tokens-file-path to store-gateway.sharding-ring.replication-factor and store-gateway.sharding-ring.tokens-file-path in anticipation of v1.4 release. #191
  • [ENHANCEMENT] Enable support for HA in the Cortex Alertmanager #147
  • [ENHANCEMENT] Support alertmanager.fallback_config option in the Alertmanager. #179
  • [ENHANCEMENT] Add support for S3 block storage. #181
  • [ENHANCEMENT] Add support for Azure block storage. #182 #190
  • [BUGFIX] Add support the local ruler client type #175
  • [BUGFIX] Fixes ruler.storage.s3.url argument for the Ruler. It used an incorrect argument. #177
