timescaledb_information.job_stats

Since 1.2.0

Shows information and statistics about jobs run by the automation framework. This includes jobs set up for user defined actions and jobs run by policies created to manage data retention, continuous aggregates, columnstore, and other automation policies. (See policies). The statistics include information useful for administering jobs and determining whether they ought be rescheduled, such as: when and whether the background job used to implement the policy succeeded and when it is scheduled to run next.

Samples

Get job success/failure information for a specific hypertable.

SELECT job_id, total_runs, total_failures, total_successes
  FROM timescaledb_information.job_stats
  WHERE hypertable_name = 'test_table';

 job_id | total_runs | total_failures | total_successes
--------+------------+----------------+-----------------
   1001 |          1 |              0 |               1
   1004 |          1 |              0 |               1

Get information about continuous aggregate policy related statistics

SELECT  js.* FROM
  timescaledb_information.job_stats js, timescaledb_information.continuous_aggregates cagg
  WHERE cagg.view_name = 'max_mat_view_timestamp'
  and cagg.materialization_hypertable_name = js.hypertable_name;
