Bugfix...

v1.5.0

Breaking Changes

• (#1478) In order to build advanced visualization features into Grafana we have decided to change our spanmetric names to match OTel conventions. This way any functionality added to Grafana will work whether you use Tempo, Grafana Agent or the OTel Collector to generate metrics. Details in the span metrics documentation.
• (#1556) Jsonnet users will need to specify ephemeral storage requests and limits for the metrics generator.
• (#1481) Anonymous usage reporting has been added. Distributors and metrics generators will now require permissions to object storage equivalent to compactors and ingesters. This feature is enabled by default but can be disabled easily.
• (#1558) Deprecated metrics tempodb_(gcs|s3|azure)_request_duration_seconds have been removed in favor of tempodb_backend_request_duration_seconds.

Changes

• [CHANGE] metrics-generator: Changed added metric label instance to __metrics_gen_instance to reduce collisions with custom dimensions. #1439 (@joe-elliott)
• [CHANGE] Don't enforce max_bytes_per_tag_values_query when set to 0. #1447 (@joe-elliott)

Additionally, default label span_status is renamed to status_code.

• [CHANGE] Update to Go 1.18 #1504 (@annanay25)
• [CHANGE] Change tag/value lookups to return partial results when reaching response size limit instead of failing #1517 (@mdisibio)
• [CHANGE] Change search to be case-sensitive #1547 (@mdisibio)
• [CHANGE] Relax Hedged request defaults for external endpoints. #1566 (@joe-elliott)

  querier:
    search:
      external_hedge_requests_at: 4s    -> 8s
      external_hedge_requests_up_to: 3  -> 2
  

• [CHANGE] BREAKING CHANGE Include emptyDir for metrics generator wal storage in jsonnet #1556 (@zalegrala)
  Jsonnet users will now need to specify a storage request and limit for the generator wal.

    _config+:: {
      metrics_generator+: {
        ephemeral_storage_request_size: '10Gi',
        ephemeral_storage_limit_size: '11Gi',
      },
    }

• [CHANGE] Two additional latency buckets added to the default settings for generated spanmetrics. Note that this will increase cardinality when using the defaults. #1593 (@fredr)
• [CHANGE] Mark log_received_traces as deprecated. New flag is log_received_spans.
  Extend distributor spans logger with optional features to include span attributes and a filter by error status. #1465 (@faustodavid)

Features

• [FEATURE] Add parquet block format #1479 #1531 #1564 (@annanay25, @mdisibio)
• [FEATURE] Add anonymous usage reporting, enabled by default. #1481 (@zalegrala)
  BREAKING CHANGE As part of the usage stats inclusion, the distributor will also require access to the store. This is required so the distirbutor can know which cluster it should be reporting membership of.
• [FEATURE] Include messaging systems and databases in service graphs. #1576 (@kvrhdn)

Enhancements

• [ENHANCEMENT] Added the ability to have a per tenant max search duration. #1421 (@joe-elliott)

  BREAKING CHANGE Removed deprecated metrics tempodb_(gcs|s3|azure)_request_duration_seconds in favor of tempodb_backend_request_duration_seconds. These metrics
  have been deprecated since v1.1.
• [ENHANCEMENT] Add tags option for s3 backends. This allows new objects to be written with the configured tags. #1442 (@stevenbrookes)
• [ENHANCEMENT] metrics-generator: support per-tenant processor configuration #1434 (@kvrhdn)

v1.5.0-rc.1

Bugfixes

• [BUGFIX] Fix issue where usage stats broke polling by creating an object that was interpreted as a tenant. #1625 (@ie-pham)

v1.5.0-rc.0

Breaking Changes

• (#1478) In order to build advanced visualization features into Grafana we have decided to change our spanmetric names to match OTel conventions. This way any functionality added to Grafana will work whether you use Tempo, Grafana Agent or the OTel Collector to generate metrics. Details below.
• (#1556) Jsonnet users will need to specify ephemeral storage requests and limits for the metrics generator.
• (#1481) Anonymous usage reporting has been added. Distributors and metrics generators will now require permissions to object storage equivalent to compactors and ingesters. This feature is enabled by default but can be disabled easily.
• (#1558) Deprecated metrics tempodb_(gcs|s3|azure)_request_duration_seconds have been removed in favor of tempodb_backend_request_duration_seconds.
