ALM-14025 Tenant File Object Usage Exceeds the Threshold
Description
The system checks the file object usage (used file objects of each directory/number of file objects allocated to each directory) of each directory associated with a tenant every hour and compares the file object usage of each directory with the threshold set for the directory. This alarm is generated when the file object usage exceeds the threshold.
This alarm is cleared when the file object usage is less than or equal to the threshold.

Impact on the System
This alarm is generated if the usage of file objects in a tenant directory exceeds the custom threshold. File writing to the directory is not affected. If the number of used file objects exceeds the maximum number of file objects allocated to the directory, the HDFS fails to write data to the directory.
Possible Causes
- The alarm threshold is improperly configured.
- The maximum number of file objects allocated to the tenant directory is inappropriate.
Procedure
Check whether the alarm threshold is appropriate.
- On MRS Manager, choose O&M > Alarm > Alarms, view the location information of the alarm, and obtain the tenant name and tenant directory for which the alarm is generated.
For details about how to log in to FusionInsight Manager, see Accessing MRS Manager.
- On Manager, click Tenant Resources, select the tenant for which the alarm is generated, and click Resources. Check whether the file object threshold configured for the tenant directory for which the alarm is generated is proper. (The default value is 90%. You can change the value as required.)
- On the Resources page, click Modify to modify or delete the file object threshold of the tenant directory for which the alarm is generated.
- About one minute later, check whether the alarm is cleared.
- If yes, no further action is required.
- If no, go to Step 5.
Check whether the maximum number of file objects allocated to the tenant is appropriate.
- On the Resources tab page of the tenant for which the alarm is generated, check whether the maximum number of file objects configured for the tenant directory is appropriate (depending on the actual service requirements of the directory).
- On the Resources page, click Modify to modify or delete the maximum number of file objects configured for the tenant directory.
- About one minute later, check whether the alarm is cleared.
- If yes, no further action is required.
- If no, go to Step 8.
Collect fault information.
- On Manager, choose O&M. In the navigation pane on the left, choose Log > Download.
- Select HDFS in the required cluster and NodeAgent under Manager from the Service.
- Click
in the upper right corner, and set Start Date and End Date for log collection to 20 minutes ahead of and after the alarm generation time, respectively. Then, click Download. - Contact O&M personnel and provide the collected logs.
Alarm Clearing
After the fault is rectified, the system automatically clears this alarm.
