ALM-29107 Tserver Process Memory Usage Exceeds the Threshold

Description

The system checks the Kudu service status every 60 seconds. This alarm is generated when the memory usage of the Kudu Tserver process exceeds the threshold.

This alarm is cleared when the memory usage of the Tserver process becomes normal and the system considers that the Kudu instance service recovers.

Attribute

Alarm ID	Alarm Severity	Auto Clear
29107	Critical	Yes

Parameters

Name	Meaning
Source	Specifies the cluster for which the alarm is generated.
ServiceName	Specifies the service for which the alarm is generated.
RoleName	Specifies the role for which the alarm is generated.
Trigger Condition	Specifies the threshold for triggering the alarm.

Impact on the System

Users cannot use the Kudu service.

Possible Causes

The memory usage of the KuduTserver instance is too high.

Procedure

Handle the Kudu instance exceptions.

On FusionInsight Manager, choose O&M > Alarm. On the displayed page, locate the alarm ALM-29107 Tserver Process Memory Usage Exceeds the Threshold and view the alarm source.
Choose O&M > Alarm > Threshold Configuration > Kudu, find the threshold of the alarm, compare the memory usage of the KuduTserver instance in the cluster with the threshold, and find the node whose memory usage exceeds the threshold.
Add nodes or reschedule jobs to reduce the memory usage of the Tserver node or change the threshold.
Choose O&M > Alarm and check whether the alarm is cleared.
- If yes, no further action is required.
- If no, go to step 4.

Collect the fault information.

On FusionInsight Manager, choose O&M. In the navigation pane on the left, choose Log > Download.
In the Service area, select the following nodes of the desired cluster.
