Details

Alive monitoring

Can monitor Pod status

Resouce monitoring

You can monitor the following resource status

  • CPU Usage

  • CPU Quota

  • Memory Usage

  • Memory Quota

  • Current Network Usage

  • Receive Bandwidth

  • Transmit Bandwidth

  • Rate of Received Packets

  • Rate of Transmitted Packets

  • Rate of Received Packets Dropped

  • Rate of Transmitted Packets Dropped

By setting alert rules based on these monitoring items, operators and operands can be monitored. For the setting method, refer to the appendix in the Reference.

If an error is detected by monitoring the operator's alive, it can be dealt with by recreating the Pod.

If resource monitoring detects an error, consider allocating more resources to the Operator or Operands.

Check the Operator Hub or Red Hat Operator Catlog page to see which version you are currently using, which can be updated, and to check for security vulnerabilities.
