Suggestions for Monitoring Alarm Configuration

We provide some general alarm configuration suggestions for your reference according to our realistic experiences.

Indicator Suggested Alarm Threshold Description
Cluster Status An alarm is given, when the monitoring value is >=2 for 10 consecutive times (i.e., in red) 0 means green, the cluster is in the healthiest status; 1 means yellow, the high availability of the cluster is affected, but the search results are still complete; 2 means red, the cluster is abnormal, the search can only return part of the data
Node Disk Util An alarm is given when the maximum value is >=75 for 10 consecutive times (more than 80% prohibited) Too high disk utilization will cause the failure of data being written normally
Node HeapMemory Util An alarm is given when the maximum value is >=85 for 10 consecutive times (more than 90% prohibited) Search performance will be affected when the value is too high
Node CPU Util An alarm is given when the maximum value is >=95 for 10 consecutive times If the CPU use rate is too high, it will decrease the cluster node processing capacity or even cause system breakdown
