• ingestion-burst-size-mb | int

  Default: 15

  This config option matches exactly Loki's ingestion_burst_size_mb, except that it is an integer here (Loki takes a float). This same value is used internally for setting per_stream_rate_limit_burst. Loki uses a default of 6 for ingestion_burst_size_mb, but 15 for per_stream_rate_limit_burst. For this reason we use 15 as the default here.

• ingestion-rate-mb | int

  Default: 4

  Per-user ingestion rate limit (MB/s). This config option matches exactly Loki's ingestion_rate_mb, except that it is an integer here (Loki takes a float). This same value is used internally for setting per_stream_rate_limit. Loki uses a default of 3 for ingestion_rate_mb, but 4 for per_stream_rate_limit. For this reason we use 4 as the default here.

  IMPORTANT: this is NOT the rate enforced by each distributor. The limit is shared evenly across distributor (write) replicas, so the effective per-distributor limit is ingestion-rate-mb / N, where N is the number of distributor replicas. If you are hitting HTTP 429 "Ingestion rate limit exceeded" errors, raise this value (multiply your desired per-distributor rate by the number of replicas).

• max-global-streams-per-user | int

  Default: 5000

  Maximum number of active streams per user, across the cluster. 0 to disable. Negative values are clamped to 0. When the global limit is enabled, each ingester is configured with a dynamic local limit based on the replication factor and the current number of healthy ingesters, and is kept updated whenever the number of ingesters changes. This config option matches Loki's max_global_streams_per_user.

• reporting_enabled | boolean

  Default: True

  Toggle anonymous reporting of usage info to Grafana. Ref: https://grafana.com/docs/loki/latest/configure/#analytics

• retention-period | int

  Sets a global retention period for log streams in Loki. A value of 0 disables retention (default). Minimum retention period is 1d. Specify the period in days. For example, to set a 48-day retention period, use 48. Specifying retention periods for individual streams is not currently supported.
