Changelog

  • [CHANGE] Cassandra backend support is now GA (stable). #3180
  • [CHANGE] Blocks storage is now GA (stable). The -experimental prefix has been removed from all CLI flags related to the blocks storage (no YAML config changes). #3180
    • -experimental.blocks-storage.* flags renamed to -blocks-storage.*
    • -experimental.store-gateway.* flags renamed to -store-gateway.*
    • -experimental.querier.store-gateway-client.* flags renamed to -querier.store-gateway-client.*
    • -experimental.querier.store-gateway-addresses flag renamed to -querier.store-gateway-addresses
  • [CHANGE] Ingester: Removed deprecated untyped record from chunks WAL. Only if you are running v1.0 or below, it is recommended to first upgrade to v1.1/v1.2/v1.3 and run it for a day before upgrading to v1.4 to avoid data loss. #3115
  • [CHANGE] Distributor API endpoints are no longer served unless target is set to distributor or all. #3112
  • [CHANGE] Increase the default Cassandra client replication factor to 3. #3007
  • [CHANGE] Blocks storage: removed the support to transfer blocks between ingesters on shutdown. When running the Cortex blocks storage, ingesters are expected to run with a persistent disk. The following metrics have been removed: #2996
    • cortex_ingester_sent_files
    • cortex_ingester_received_files
    • cortex_ingester_received_bytes_total
    • cortex_ingester_sent_bytes_total
  • [CHANGE] The buckets for the cortex_chunk_store_index_lookups_per_query metric have been changed to 1, 2, 4, 8, 16. #3021
  • [CHANGE] Blocks storage: the operation label value getrange has changed into get_range for the metrics thanos_store_bucket_cache_operation_requests_total and thanos_store_bucket_cache_operation_hits_total. #3000
  • [CHANGE] Experimental Delete Series: /api/v1/admin/tsdb/delete_series and /api/v1/admin/tsdb/cancel_delete_request purger APIs to return status code 204 instead of 200 for success. #2946
  • [CHANGE] Histogram cortex_memcache_request_duration_seconds method label value changes from Memcached.Get to Memcached.GetBatched for batched lookups, and is not reported for non-batched lookups (label value Memcached.GetMulti remains, and had exactly the same value as Get in nonbatched lookups). The same change applies to tracing spans. #3046
  • [CHANGE] TLS server validation is now enabled by default, a new parameter tls_insecure_skip_verify can be set to true to skip validation optionally. #3030
  • [CHANGE] cortex_ruler_config_update_failures_total has been removed in favor of cortex_ruler_config_last_reload_successful. #3056
  • [CHANGE] ruler.evaluation_delay_duration field in YAML config has been moved and renamed to limits.ruler_evaluation_delay_duration. #3098
  • [CHANGE] Removed obsolete results_cache.max_freshness from YAML config (deprecated since Cortex 1.2). #3145

Cortex 1.3.0

This Cortex release features 125 contributions from 37 different authors. It's yet another great milestone we have reached thanks to the amazing support from our community ❤️ Thanks!

Highlights:

  • The blocks storage is getting closer to production readiness. In this release we've done several fixes and improvements. In particular, you should be aware of:
    • Some CLI flags and YAML config options have been renamed
    • The store-gateway service is now mandatory when running the blocks storage
    • Introduced support for a live cluster migration from chunks to blocks (and rollback)
    • Introduced support to flush blocks on-demand from ingesters
  • The ruler and alertmanager got several improvements, including but not limited to:
    • The ruler now runs in the single binary when Cortex gets started with -target=all
    • Introduced new config options to fine-tune the ruler
    • Introduced support to load locally stored rules (eg. loaded via Kubernetes config map)
    • Multiple alertmanager URLs can now be specified in the ruler; each URL is treated as a separate alertmanager group
    • Alertmanager configuration can be persisted to object storage via API
  • Other changes worth to note:
    • Added optional snappy compression support to internal gRPC connections
    • Starting from this release we're going to publish .rpm and .deb packages too

Please refer to the full changelog for full list of changes and improvements.

Changelog

  • [CHANGE] Replace the metric cortex_alertmanager_configs with cortex_alertmanager_config_invalid exposed by Alertmanager. #2960
  • [CHANGE] Experimental Delete Series: Change target flag for purger from data-purger to purger. #2777
  • [CHANGE] Experimental blocks storage: The max concurrent queries against the long-term storage, configured via -experimental.blocks-storage.bucket-store.max-concurrent, is now a limit shared across all tenants and not a per-tenant limit anymore. The default value has changed from 20 to 100 and the following new metrics have been added: #2797
    • cortex_bucket_stores_gate_queries_concurrent_max
    • cortex_bucket_stores_gate_queries_in_flight
    • cortex_bucket_stores_gate_duration_seconds
  • [CHANGE] Metric cortex_ingester_flush_reasons has been renamed to cortex_ingester_flushing_enqueued_series_total, and new metric cortex_ingester_flushing_dequeued_series_total with outcome label (superset of reason) has been added. #2802 #2818 #2998
  • [CHANGE] Experimental Delete Series: Metric cortex_purger_oldest_pending_delete_request_age_seconds would track age of delete requests since they are over their cancellation period instead of their creation time. #2806
  • [CHANGE] Experimental blocks storage: the store-gateway service is required in a Cortex cluster running with the experimental blocks storage. Removed the -experimental.tsdb.store-gateway-enabled CLI flag and store_gateway_enabled YAML config option. The store-gateway is now always enabled when the storage engine is blocks. #2822
  • [CHANGE] Experimental blocks storage: removed support for -experimental.blocks-storage.bucket-store.max-sample-count flag because the implementation was flawed. To limit the number of samples/chunks processed by a single query you can set -store.query-chunk-limit, which is now supported by the blocks storage too. #2852
  • [CHANGE] Ingester: Chunks flushed via /flush stay in memory until retention period is reached. This affects cortex_ingester_memory_chunks metric. #2778
  • [CHANGE] Querier: the error message returned when the query time range exceeds -store.max-query-length has changed from invalid query, length > limit (X > Y) to the query time range exceeds the limit (query length: X, limit: Y). #2826
  • [CHANGE] Add component label to metrics exposed by chunk, delete and index store clients. #2774
  • [CHANGE] Querier: when -querier.query-ingesters-within is configured, the time range of the query sent to ingesters is now manipulated to ensure the query start time is not older than 'now - query-ingesters-within'. #2904
  • [CHANGE] KV: The role label which was a label of multi KV store client only has been added to metrics of every KV store client. If KV store client is not multi, then the value of role label is primary. #2837
  • [CHANGE] Added the engine label to the metrics exposed by the Prometheus query engine, to distinguish between ruler and querier metrics. #2854
  • [CHANGE] Added ruler to the single binary when started with -target=all (default). #2854
  • [CHANGE] Experimental blocks storage: compact head when opening TSDB. This should only affect ingester startup after it was unable to compact head in previous run. #2870
  • [CHANGE] Metric cortex_overrides_last_reload_successful has been renamed to cortex_runtime_config_last_reload_successful. #2874
  • [CHANGE] HipChat support has been removed from the alertmanager (because removed from the Prometheus upstream too). #2902
  • [CHANGE] Add constant label name to metric cortex_cache_request_duration_seconds. #2903
  • [CHANGE] Add user label to metric cortex_query_frontend_queue_length. #2939
  • [CHANGE] Experimental blocks storage: cleaned up the config and renamed "TSDB" to "blocks storage". #2937
    • The storage engine setting value has been changed from tsdb to blocks; this affects -store.engine CLI flag and its respective YAML option.
    • The root level YAML config has changed from tsdb to blocks_storage
    • The prefix of all CLI flags has changed from -experimental.tsdb. to -experimental.blocks-storage.
    • The following settings have been grouped under tsdb property in the YAML config and their CLI flags changed:
      • -experimental.tsdb.dir changed to -experimental.blocks-storage.tsdb.dir
      • -experimental.tsdb.block-ranges-period changed to -experimental.blocks-storage.tsdb.block-ranges-period
      • -experimental.tsdb.retention-period changed to -experimental.blocks-storage.tsdb.retention-period
      • -experimental.tsdb.ship-interval changed to -experimental.blocks-storage.tsdb.ship-interval
      • -experimental.tsdb.ship-concurrency changed to -experimental.blocks-storage.tsdb.ship-concurrency
      • -experimental.tsdb.max-tsdb-opening-concurrency-on-startup changed to -experimental.blocks-storage.tsdb.max-tsdb-opening-concurrency-on-startup
      • -experimental.tsdb.head-compaction-interval changed to -experimental.blocks-storage.tsdb.head-compaction-interval
      • -experimental.tsdb.head-compaction-concurrency changed to -experimental.blocks-storage.tsdb.head-compaction-concurrency
      • -experimental.tsdb.head-compaction-idle-timeout changed to -experimental.blocks-storage.tsdb.head-compaction-idle-timeout
      • -experimental.tsdb.stripe-size changed to -experimental.blocks-storage.tsdb.stripe-size
      • -experimental.tsdb.wal-compression-enabled changed to -experimental.blocks-storage.tsdb.wal-compression-enabled
      • -experimental.tsdb.flush-blocks-on-shutdown changed to -experimental.blocks-storage.tsdb.flush-blocks-on-shutdown
  • [CHANGE] Flags -bigtable.grpc-use-gzip-compression, -ingester.client.grpc-use-gzip-compression, -querier.frontend-client.grpc-use-gzip-compression are now deprecated. #2940
  • [CHANGE] Limit errors reported by ingester during query-time now return HTTP status code 422. #2941
  • [FEATURE] Introduced ruler.for-outage-tolerance, Max time to tolerate outage for restoring "for" state of alert. #2783
  • [FEATURE] Introduced ruler.for-grace-period, Minimum duration between alert and restored "for" state. This is maintained only for alerts with configured "for" time greater than grace period. #2783
  • [FEATURE] Introduced ruler.resend-delay, Minimum amount of time to wait before resending an alert to Alertmanager. #2783
  • [FEATURE] Ruler: added local filesystem support to store rules (read-only). #2854
  • [ENHANCEMENT] Upgraded Docker base images to alpine:3.12. #2862
  • [ENHANCEMENT] Experimental: Querier can now optionally query secondary store. This is specified by using -querier.second-store-engine option, with values chunks or blocks. Standard configuration options for this store are used. Additionally, this querying can be configured to happen only for queries that need data older than -querier.use-second-store-before-time. Default value of zero will always query secondary store. #2747
  • [ENHANCEMENT] Query-tee: increased the cortex_querytee_request_duration_seconds metric buckets granularity. #2799
  • [ENHANCEMENT] Query-tee: fail to start if the configured -backend.preferred is unknown. #2799
  • [ENHANCEMENT] Ruler: Added the following metrics: #2786
    • cortex_prometheus_notifications_latency_seconds
    • cortex_prometheus_notifications_errors_total
    • cortex_prometheus_notifications_sent_total
    • cortex_prometheus_notifications_dropped_total
    • cortex_prometheus_notifications_queue_length
    • cortex_prometheus_notifications_queue_capacity
    • cortex_prometheus_notifications_alertmanagers_discovered
  • [ENHANCEMENT] The behavior of the /ready was changed for the query frontend to indicate when it was ready to accept queries. This is intended for use by a read path load balancer that would want to wait for the frontend to have attached queriers before including it in the backend. #2733
  • [ENHANCEMENT] Experimental Delete Series: Add support for deletion of chunks for remaining stores. #2801
  • [ENHANCEMENT] Add -modules command line flag to list possible values for -target. Also, log warning if given target is internal component. #2752
  • [ENHANCEMENT] Added -ingester.flush-on-shutdown-with-wal-enabled option to enable chunks flushing even when WAL is enabled. #2780
  • [ENHANCEMENT] Query-tee: Support for custom API prefix by using -server.path-prefix option. #2814
  • [ENHANCEMENT] Query-tee: Forwar...

Cortex 1.2.0

This release has a number of bug-fixes and enhancements, particularly:

  • Memberlist KV client is no longer considered experimental. #2725
  • 3rd-party index and chunk stores using gRPC client/server plugin mechanism (experimental) #2220
  • Using an invalid flag no longer causes printing of all available flags. #2691 (my favourite change!)

Many thanks to all contributors.

Detailed list of changes:

  • [CHANGE] Metric cortex_kv_request_duration_seconds now includes name label to denote which client is being used as well as the backend label to denote the KV backend implementation in use. #2648
  • [CHANGE] Experimental Ruler: Rule groups persisted to object storage using the experimental API have an updated object key encoding to better handle special characters. Rule groups previously-stored using object storage must be renamed to the new format. #2646
  • [CHANGE] Query Frontend now uses Round Robin to choose a tenant queue to service next. #2553
  • [CHANGE] -promql.lookback-delta is now deprecated and has been replaced by -querier.lookback-delta along with lookback_delta entry under querier in the config file. -promql.lookback-delta will be removed in v1.4.0. #2604
  • [CHANGE] Experimental TSDB: removed -experimental.tsdb.bucket-store.binary-index-header-enabled flag. Now the binary index-header is always enabled.

The corresponding YAML config parameter has been changed from results_cache.max_freshness to limits_config.max_cache_freshness. The legacy YAML config parameter (results_cache.max_freshness) will continue to be supported till Cortex release v1.4.0. #2609

  • [CHANGE] Available command-line flags are printed to stdout, and only when requested via -help. Using invalid flag no longer causes printing of all available flags. #2691
  • [CHANGE] Experimental Memberlist ring: randomize gossip node names to avoid conflicts when running multiple clients on the same host, or reusing host names (eg. pods in statefulset). Node name randomization can be disabled by using -memberlist.randomize-node-name=false. #2715
  • [CHANGE] Memberlist KV client is no longer considered experimental. #2725
  • [CHANGE] Change target flag for purger from data-purger to purger and make delete request cancellation duration configurable. #2760
  • [CHANGE] Removed -store.fullsize-chunks option which was undocumented and unused (it broke ingester hand-overs). #2656
  • [CHANGE] Query with no metric name that has previously resulted in HTTP status code 500 now returns status code 422 instead. #2571
  • [FEATURE] TLS config options added for GRPC clients in Querier (Query-frontend client & Ingester client), Ruler, Store Gateway, as well as HTTP client in Config store client. #2502
  • [FEATURE] The flag -frontend.max-cache-freshness is now supported within the limits overrides, to specify per-tenant max cache freshness values. The corresponding YAML config parameter has been changed from results_cache.max_freshness to limits_config.max_cache_freshness. The legacy YAML config parameter (results_cache.max_freshness) will continue to be supported till Cortex release v1.4.0. #2609
  • [FEATURE] Experimental gRPC Store: Added support to 3rd parties index and chunk stores using gRPC client/server plugin mechanism. #2220
  • [ENHANCEMENT] Propagate GOPROXY value when building build-image. This is to help the builders building the code in a Network where default Go proxy is not accessible (e.g. when behind some corporate VPN). #2741
  • [ENHANCEMENT] Querier: Added metric cortex_querier_request_duration_seconds for all requests to the querier. #2708
  • [ENHANCEMENT] Cortex is now built with Go 1.14. #2480 #2749 #2753
  • [ENHANCEMENT] Experimental TSDB: added the following metrics to the ingester: #2580 #2583 #2589 #2654
    • cortex_ingester_tsdb_appender_add_duration_seconds

1.1.0 / 2020-05-21

This release brings the usual mix of bugfixes and improvements. The biggest change is that WAL support for chunks is now considered to be production-ready!

Please make sure to review renamed metrics, and update your dashboards and alerts accordingly.

  • [CHANGE] Added v1 API routes documented in #2327. #2372
    • Added -http.alertmanager-http-prefix flag which allows the configuration of the path where the Alertmanager API and UI can be reached. The default is set to /alertmanager.
    • Added -http.prometheus-http-prefix flag which allows the configuration of the path where the Prometheus API and UI can be reached. The default is set to /prometheus.
    • Updated the index hosted at the root prefix to point to the updated routes.
    • Legacy routes hardcoded with the /api/prom prefix now respect the -http.prefix flag.
  • [CHANGE] The metrics cortex_distributor_ingester_appends_total and distributor_ingester_append_failures_total now include a type label to differentiate between samples and metadata. #2336
  • [CHANGE] The metrics for number of chunks and bytes flushed to the chunk store are renamed. Note that previous metrics were counted pre-deduplication, while new metrics are counted after deduplication. #2463
    • cortex_ingester_chunks_stored_total > cortex_chunk_store_stored_chunks_total
    • cortex_ingester_chunk_stored_bytes_total > cortex_chunk_store_stored_chunk_bytes_total

  • [CHANGE] WAL: WAL and checkpoint compression is now disabled. #2436
  • [CHANGE] Update in dependency go-kit/kit from v0.9.0 to v0.10.0. HTML escaping disabled in JSON Logger. #2535
  • [CHANGE] Experimental TSDB: Removed cortex_<service>_ prefix from Thanos objstore metrics and added component label to distinguish which Cortex component is doing API calls to the object storage when running in single-binary mode: #2568
    • cortex_<service>_thanos_objstore_bucket_operations_total renamed to thanos_objstore_bucket_operations_total{component="<name>"}
    • cortex_<service>_thanos_objstore_bucket_operation_failures_total renamed to thanos_objstore_bucket_operation_failures_total{component="<name>"}
