Grafana Mimir version 2.13.0-rc.0 release notes
Features and enhancements
-
Improved CPU performance in processing queries with regular expressions that contain many alternations (for example
foo|bar|baz|...
). -
Improved OTLP ingestion performance by using native translation, which reduces memory usage in the distributor by up to 30% and CPU usage by up to 8%.
-
Configurable S3 bucket lookup type improves interoperability with S3-compatible providers, such as Tencent and Alibaba. Configure lookup type via
-<prefix>.s3.bucket-lookup-type
or-common.storage.s3-bucket-lookup-type
. -
Configuration of TLS for S3 buckets is now possible via
-<prefix>.s3.http.*
and-common.storage.s3.http.*
configuration options. -
Mimirtool can now verify the validity of a Mimir runtime configuration file with the
mimirtool runtime-config verify
command. -
Active series are now updated along with owned series. This means the number of active series for a tenant is more accurate after scaling out ingesters. As a result, ingesters now more precisely enforce tenants' series limits. This feature is only enabled when
-ingester.track-ingester-owned-series
or-ingester.use-ingester-owned-series-for-limits
are enabled. -
Store-gateway can be configured to explicitly disable or enable tenants. This is useful in cases where compaction slows down for a tenant to temporarily exclude another tenant while compaction catches up without affecting other tenants.
-
Remote read (
/prometheus/api/v1/read
) is becoming a first-class endpoint in Mimir with support inquery stats
logs and query blocking in the query-frontend. More coming in future releases.
Additionally, the following previously experimental features are now considered stable:
- Rules tenant federation via the
source_tenants
field in rule groups. - Enabling recording, and alerting rules evaluation on a per-tenant basis.
- Limiting the number of tenants a federated query can query.
Important changes
In Grafana Mimir 2.13 the following behavior has changed:
-
The default Docker image
grafana/mimir
is now based on the distroless imagegcr.io/distroless/static-debian12
.
See Debugging distroless container images for more details on how to
work with distroless images. -
Error logs in the ingester are now sampled at 10% by default. Sampled log lines contain
(sampled 1/10)
. Thecortex_discarded_samples_total
metric still tracks all discarded samples. -
Anonymous usage statistics now include actual CPU usage instead of available CPU cores.
-
Continuous-test is no longer a standalone binary and is now part of Mimir as its own target. The published Docker image has been updated to use the new packaging.
The following deprecated configuration options are removed in Grafana Mimir 2.13:
- The configuration option
-log.buffered
, which was deprecated in 2.11 and is now enabled by default.
Experimental features
Grafana Mimir 2.13 includes new features that are considered experimental and disabled by default.
Use them with caution and report any issues you encounter:
- Experimental support for server-side circuit breakers in ingesters on read and write requests. This can be enabled using
-ingester.push-circuit-breaker.enabled
and-ingester.read-circuit-breaker.enabled
options and further configured via the-ingester.push-circuit-breaker.*
and-ingester.read-circuit-breaker.*
options.
The following configuration options are deprecated and will be removed in a future Grafana Mimir release:
evaluation_delay
field in the rule group configuration has been deprecated. Please usequery_offset
instead.
Bug fixes
- OTLP ingestion: translate all HTTP 5xx errors into one of 502, 503, or 504, so that the otel-collector retries the failed requests.
- OTLP ingestion: return properly formatted protobuf error messages when ingestion fails.
- OTLP ingestion: generate
target_info
metric only when there are metrics in the request and there is at least one configured identifying label. - OTLP ingestion: don't discard timeseries paired with invalid exemplars. Instead, try to ingest the timeseries and discard only the invalid exemplars.
- Subqueries:
@ end()
and@ start()
now work correctly with queries split by time. - Native histograms: order exemplars before ingestion to improve success rate when ingesting multiple exemplars.
- Native histograms: return HTTP 400 on invalid native histogram samples instead of HTTP 500. The metric
cortex_discarded_samples_total{reason="invalid-native-histogram"}
is now incremented on invalid histogram samples.
Changelog
2.13.0-rc.0
Grafana Mimir
- [CHANGE] Build:
grafana/mimir
docker image is now based ongcr.io/distroless/static-debian12
image. Alpine-based docker image is still available asgrafana/mimir-alpine
, until Mimir 2.15. #8204 #8235 - [CHANGE] Ingester:
/ingester/flush
endpoint is now only allowed to execute only while the ingester is inRunning
state. The 503 status code is returned if the endpoint is called while the ingester is not inRunning
state. #7486 - [CHANGE] Distributor: Include label name in
err-mimir-label-value-too-long
error message: #7740 - [CHANGE] Ingester: enabled 1 out 10 errors log sampling by default. All the discarded samples will still be tracked by the
cortex_discarded_samples_total
metric. The feature can be configured via-ingester.error-sample-rate
(0 to log all errors). #7807 - [CHANGE] Query-frontend: Query results caching and experimental query blocking now utilize the PromQL string-formatted query format rather than the unvalidated query as submitted to the frontend. #7742
- Query results caching should be more stable as all equivalent queries receive the same cache key, but there may be cache churn on first deploy with the updated format
- Query blocking can no longer be circumvented with an equivalent query in a different format; see Configure queries to block
- [CHANGE] Query-frontend: stop using
-validation.create-grace-period
to clamp how far into the future a query can span. #8075 - [CHANGE] Clamp
GOMAXPROCS
toruntime.NumCPU
. #8201 - [CHANGE] Anonymous usage statistics tracking: add CPU usage percentage tracking. #8282
- [CHANGE] Added new metric
cortex_compactor_disk_out_of_space_errors_total
which counts how many times a compaction failed due to the compactor being out of disk. #8237 - [CHANGE] Anonymous usage statistics tracking: report active series in addition to in-memory series. #8279
- [CHANGE] Ruler:
evaluation_delay
field in the rule group configuration has been deprecated. Please usequery_offset
instead (it has the same exact meaning and behaviour). #8295 - [CHANGE] General: remove
-log.buffered
. The configuration option has been enabled by default and deprecated since Mimir 2.11. #8395 - [CHANGE] Ruler: promote tenant federation from experimental to stable. #8400
- [CHANGE] Ruler: promote
-ruler.recording-rules-evaluation-enabled
and-ruler.alerting-rules-evaluation-enabled
from experimental to stable. #8400 - [CHANGE] General: promote
-tenant-federation.max-tenants
from experimental to stable. #8400 - [FEATURE] Continuous-test: now runable as a module with
mimir -target=continuous-test
. #7747 - [FEATURE] Store-gateway: Allow specific tenants to be enabled or disabled via
-store-gateway.enabled-tenants
or-store-gateway.disabled-tenants
CLI flags or their corresponding YAML settings. #7653 - [FEATURE] New
-<prefix>.s3.bucket-lookup-type
flag configures lookup style type, used to access bucket in s3 compatible providers. #7684 - [FEATURE] Querier: add experimental streaming PromQL engine, enabled with
-querier.promql-engine=mimir

/ingester/unregister-on-shutdown
HTTP endpoint allows dynamic access to ingesters'-ingester.ring.unregister-on-shutdown
configuration. #7739 - [FEATURE] Server: added experimental PROXY protocol support. The PROXY protocol support can be enabled via
-server.proxy-protocol-enabled=true
. When enabled, the support is added both to HTTP and gRPC listening ports. #7698 - [FEATURE] Query-frontend, querier: new experimental
/cardinality/active_native_histogram_metrics
API to get active native histogram metric names with statistics about active native histogram buckets. #7982 #7986 #8008 - [FEATURE] Alertmanager: Added
-alertmanager.max-silences-count
and-alertmanager.max-silence-size-bytes
to set limits on per tenant silences. Disabled by default. #8241 #8249 - [FEATURE] Ingester: add experimental support for the server-side circuit breakers when writing to and reading from ingesters. This can be enabled using
-ingester.push-circuit-breaker.enabled
and-ingester.read-circuit-breaker.enabled

-blocks-storage.bucket-store.max-concurrent-queue-timeout
. When set, queries at the store-gateway's query gate will not wait longer than that to execute. If a query reaches the wait timeout, then the querier will retry the blocks on a different store-gateway. If all store-gateways are unavailable, then the query will fail witherr-mimir-store-consistency-check-failed
. #7777 #8149 - [ENHANCEMENT] Store-gateway: add
-blocks-storage.bucket-store.index-header.lazy-loading-concurrency-queue-timeout
. When set, loads of index-headers at the store-gateway's index-header lazy load gate will not wait longer than that to execute.

cortex_discarded_samples_total
will be increased with thereason
label set to"invalid-native-histogram"
. #7736 #7773 - [BUGFIX] Do not wrap error message with
sampled 1/<frequency>
if it's not actually sampled. #7784 - [BUGFIX] Store-gateway: do not track cortex_querier_blocks_consistency_checks_failed_total metric if query has been canceled or interrued due to any error not related to blocks consistency check failed. #7752
