oms_host_threshold

Impact on the system

This alert may affect the creation and performance of some tasks.

Possible causes

The CPU utilization, memory usage, or disk usage is high.

The following table lists the limits of the CPU utilization, memory usage, and disk usage for the OceanBase Migration Service (OMS) server.

Solution

End unwanted data migration or synchronization tasks to reduce the host load. You can also scale out the OMS cluster.

To modify the CPU utilization, memory usage, and disk usage thresholds, perform the following steps:

1. Log in to the OMS container.

   docker exec -it ${CONTAINER_NAME} bash
   

   Notice

   CONTAINER_NAME specifies the name of the container.

2. In the drc-cm.properties file in the /home/admin/conf/cm/ directory, add the parameters drcCfg.cpuUsedPercentThresHold (default value: 0.85), drcCfg.memUsedPercentThresHold (default value: 0.80), and drcCfg.diskUsedPercentThresHold (default value: 0.90) to specify thresholds.

3. Restart the oms_drc_cm service of OMS.

   supervisorctl restart oms_drc_cm
