VPLEX: How to reduce Java's high CPU utilization on the management server.

Restart the Management Station console from the management server using the command;
sudo /etc/init.d/VPlexManagementConsole restart

Checking the VPLEX management server Java utilization shows that it is consuming over 100%.

This can be seen in environments that have been up for extended periods of time. In these situations, the services running on the management server can start to consume too many resources.

Before restarting any management console or management server, ensure that there are no ongoing migrations (device or extent)

Run the below commands on the Management Station console:

Step 1: Verify the management server console's pid:

Example:
service@#########:~> sudo /etc/init.d/VPlexManagementConsole status
VPlexManagementConsole is running (pid 11315)

Step 2: Restarting of management server console: (to restart the Management Server software.)

Example:
service@#########:~> sudo /etc/init.d/VPlexManagementConsole restart
Restarting EMC VPlex Management Console... done

Step 3: Post restarting the management server software verify the pid:

Example:
service@#########:~> sudo /etc/init.d/VPlexManagementConsole status
VPlexManagementConsole is running (pid 23533)


Check if the issue is resolved after the restart.
