Metrics t through z

tablet_base_max_compaction_score​

  • Unit: -
  • Description: Highest base compaction score of tablets in this BE.

tablet_cumulative_max_compaction_score​

  • Unit: -
  • Description: Highest cumulative compaction score of tablets in this BE.

tablet_metadata_mem_bytes​

  • Unit: Bytes
  • Description: Memory used by tablet metadata.

tablet_schema_mem_bytes​

  • Unit: Bytes
  • Description: Memory used by tablet schema.

tablet_update_max_compaction_score​

  • Unit: -
  • Description: Highest compaction score of tablets in Primary Key tables in the current BE.

threadpool_task_exception_total​

  • Unit: Count
  • Description: Cumulative number of task exceptions caught and swallowed by ThreadPool worker threads across the BE process. Increments only when enable_threadpool_catch_task_exception is true. When that item is false (default), this metric stays unchanged because there is no enclosing catch clause.
