Configuring Cluster Monitoring

You can use Cloud Eye to monitor the created clusters. After configuring the cluster monitoring, you can log in to the Cloud Eye management console to view cluster metrics.

The procedure for configuring cluster monitoring:

  1. Creating Alarm Rules: Customize alarm rules for the monitoring metrics. Once a metric exceeds the threshold, the system will notify you by sending emails or HTTP/HTTPS requests.
  2. Configuring Monitoring Metrics: Configure monitoring metrics for a cluster or a node in the cluster.
  3. Viewing Monitoring Metrics: View the statistics of the monitoring metrics in specific periods.

Prerequisites

  • The cluster is in the Available or Processing status.
  • The cluster has been running properly for more than 10 minutes.

Recommended Monitoring Metrics

  • Cluster CPU and JVM usage. You are advised to configure the following monitoring metrics: average JVM heap usage, maximum JVM heap usage, average CPU usage, and maximum CPU usage.
  • Cluster write and query latency and throughput. You are advised to configure the following monitoring metrics: average index latency, average index rate, average search latency, and average QPS.
  • Cluster write and query queue and rejected tasks. You are advised to configure the following monitoring metrics: tasks in write queue, tasks in search queue, rejected tasks in write queue, and rejected tasks in search queue.
