This instruction concerns alarm handling.
1.1 Compute Resource Threshold Value Exceeded Alarm Description
The alarm is a primary alarm. The severity of the alarm is Minor. The alarm is issued by the MrfInstance MO.

|---|---|---|---|---|
|
High threshold for vMRF instance compute resource has been exceeded. |
The vMRF instance is soon running out of allocated compute resources. |
At least 50% of the available storage disk space is used. At least 80% of the available memory is used. |
vMRF VM |
No traffic impact, storage of new files on the disk might fail. Call failures can occur if memory use further increases. |
A compute resource type that is not yet in the Additional Text field exceeds its high threshold value. The compute resource is added to Additional Text.
A compute resource type that is in the Additional Text field goes below its low threshold value. The compute resource is removed from Additional Text.
Both compute resource types are below their low threshold values for at least 30 seconds.

2 Cease the Compute Resource Threshold Value Exceeded Alarm
The following procedure describes how to cease the Compute Resource Threshold Value Exceeded alarm.
Prerequisites
You have logged into the node.
Steps
-
See details for the alarm Compute Resource Threshold Value Exceeded. Check the
Additional Text field of the alarm.
If the Additional Text includes disk used, compare the value of the diskSize counter against the storage requirements in vMRF Infrastructure Requirements. If the allocated disk space is below the required value, allocate more storage space to meet requirements. If the alarm is ceased, continue to Perform Concluding Routines.
If the Additional Text includes memory used, compare the value of the memoryTotal counter against the compute requirements in vMRF Infrastructure Requirements. If the allocated memory is below the required value, allocate more memory to meet requirements. If the alarm is ceased, continue to Perform Concluding Routines.
-
If the alarm is still active,
depending
on the Additional Text field, do the
following:
If the Additional Text includes disk used, open an SSH connection to the VM from which the alarm is issued and clean up disk space by removing possible core dumps from /cluster/storage/dumps/ and tracing-related files from /cluster/storage/collectdata. If the alarm is ceased, continue to Perform Concluding Routines.
If the Additional Text includes memory used, monitor memory use by checking the memoryUsed counter and compare the results with other VMs. If high memory use only appears in the monitored VM, lock and restart the VM issuing the alarm.
If the alarm is ceased, continue to Perform Concluding Routines.
- If the alarm is still active, contact Ericsson support. Further actions are outside the scope of this instruction. Continue to Perform Concluding Routines.
