Impact on the System

If LDMS fails to schedule and submit jobs, the reliability of the hosted table is affected. If the failure lasts for a long time, the read and write performance of the hosted tables will be affected and the tables may be unavailable.

Possible Causes

The service on which LDMS depends is faulty, or resources are insufficient for scheduling too many jobs on the background.

Handling Procedure

1. Log in to FusionInsight Manager, choose O&M > Alarm > Alarms, click Failed to submit the task, and check the Location information. Check the host information of the node where the instance for which the alarm is generated is located.

2. On FusionInsight Manager, choose Cluster > Services > LDMS > Instances.
3. Click the instance role for which the alarm is generated and choose Dashboard > Log > LDMSServer.
