The memory setting for the Extreme Management Center server JVM and mysql should not exceed more than 70% of the physical memory to avoid the system from paging memory to disk, i.e. the Xmx memory setting should not exceed 70% of the system memory
Here are the recommended settings for the server based on system memory: System sizing recommendations may be found in the Extreme Management Center Release Notes.
To edit the memory settings edit the nsserver.cfg file on the server system as follows.nsserver.cfg locationWindows:
c:\Program Files\Extreme Networks\NetSight\servicesLinux/Ubuntu:
The MetaspaceSize setting should be 256m. The nsserver .cfg file should look like this for a Large system:
-Xms24g -Xmx36g -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=../../nsdump.hprof -XX:MetaspaceSize=256m
After editing the file with the suggested Xms and XmX settings, restart the NetSight services to implement the changes in memory allocation.
Restarting in Windows: Right click on the services icon for NetSight and select Restart Running Services or Start Services if the server isn't currently running.
Restarting in Linux: issue the command: service nsserver restart
