Impala query counter metrics

Use Impala query counter metrics to get information about the rate of Impala queries.

Include the following in the SELECT statement of the tsquery:
  • counter_delta(queries_ingested_rate)
  • counter_delta(queries_successful_rate)
  • counter_delta(queries_rejected_rate)
  • counter_delta(queries_oom_rate)
  • counter_delta(queries_timed_out_rate)
  • counter_delta(impala_query_admission_wait_rate)
  • counter_delta(impala_query_memory_spilled_rate)

For example:

SELECT
   counter_delta(queries_ingested_rate)
   WHERE
   category=IMPALA_POOL
   AND clusterName=Cluster_Name
   AND serviceName=Service_Name
