Note: In version 8.4.1 - the need to edit these files will be deprecated. So this pertains only to prior releases.
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
