Impact on the System

The server efficiency decreases, and tasks may fail.

Possible Causes

• The load tilt is large, and the load pressure is high.
• The alarm threshold or alarm trigger count is improperly configured.

Handling Procedure

Check whether the alarm threshold or alarm trigger count is properly configured.

1. Log in to FusionInsight Manager and choose O&M > Alarm > Thresholds > MemArtsStore > Resources > Ratio of StoreWorker write resource usage to the flow control threshold (StoreWorker).
2. Click the edit button next to Trigger Count, change the number based on site requirements, and click OK.
   

   Trigger Count specifies how many times the threshold can be hit before an alarm is generated.

3. Click Modify in the Operation column, change the alarm threshold based on site requirements, and click OK.
4. Wait 2 minutes and check whether the alarm is automatically cleared.
   • If yes, no further action is required.
   • If no, go to Step 5.

Collect fault information.

5. On FusionInsight Manager, choose O&M. In the navigation pane on the left, choose Log > Download.
6. Expand the Service drop-down list, and select MemArtsStore for the target cluster.
7. Click the edit icon in the upper right corner, and set Start Date and End Date for log collection to 10 minutes ahead of and after the alarm generation time, respectively. Then, click Download.
8. Contact O&M engineers and send the collected logs.

Alarm Clearance

This alarm is automatically cleared after the fault is rectified.
