Module mz_storage_client::statistics

These structure represents a full set up updates for the mz_source_statistics_raw and mz_sink_statistics_raw tables for a specific source-worker/sink-worker pair. They are structured like this for simplicity and efficiency: Each storage worker can individually collect and consolidate metrics, then control how much StorageResponse traffic is produced when sending updates back to the controller to be written.

The proto conversions for this types are in the client module, for now.

Structs

• Boolean
  A boolean gauge that is never reset.
• Counter
  A counter that never resets.
• Gauge
  A gauge that has semantics based on the StorageMetric implementation of its inner.
• ProtoSinkStatisticsUpdate
• ProtoSourceStatisticsUpdate
• ResettingLatency
  A latency gauge that is reset on every restart.
• ResettingNullableTotal
  A numerical gauge that is always resets, but can start out as NULL.
• ResettingTotal
  A numerical gauge that is always resets.
• SinkStatisticsUpdate
  An update as reported from a storage instance. The semantics of each field are documented above in MZ_SINK_STATISTICS_RAW_DESC, and encoded in the field types.
• SourceStatisticsUpdate
  An update as reported from a storage instance. The semantics of each field are documented above in MZ_SOURCE_STATISTICS_RAW_DESC, and encoded in the field types.
• Total
  A numerical gauge that never regresses.
• WebhookStatistics
  Statistics for webhooks.

Statics

Traits
