Alarm Triggering Scenarios

  • 16000: An alarm is triggered when the ratio of the number of sessions connected to HiveServer to the allowed total number of sessions exceeds the threshold. For example, if the number of connected sessions is 9, the allowed total number of sessions is 12, and the threshold is 70%, an alarm is triggered, because 9/12 > 70%.
  • 16001: An alarm is triggered when the ratio of HDFS capacities used by Hive to total HDFS capacities allocated to Hive exceeds the threshold. For example, if 500 GB is allocated to Hive, Hive uses 400 GB, and the threshold is 75%, an alarm is triggered, because 400/500 > 75%.
  • 16002: An alarm is triggered when SQL execution success rate is lower than the threshold. If two out of four SQL statements are executed successfully and the threshold is 60%, an alarm is triggered, because 2/4 < 60%.
  • 16004: An alarm is triggered when the health status of the Hive service changes to Bad.
  • MRS Manager: To set the alarm threshold, alarm severity, and alarm triggering time segment, choose System > Configure Alarm Threshold on MRS Manager.FusionInsight Manager: Choose O&M > Alarm > Thresholds to set the alarm threshold, alarm severity, and alarm triggering time range.
  • Metrics related to Hive running can be viewed on the Hive monitoring interface.
