After changing one of the above values you will have to restart the sysmon servce

service sysmon restart

and wait for 5 minutes for the new data to be displayed in server manager.

When upgrading to a newer version, all Sysmon data will be automatically backed up to a backup directory /var/lib/rrd/backup/ If you upgraded from at least version 6.1, you can bring back old Sysmon data, thus retaining the Sysmon history. Please use the following commands to restore Sysmon history data:

service sysmon stop
cp -f /var/lib/rrd/backup/*.rrd /var/lib/rrd/
service sysmon start

yum remove smeserver-sysmon

Remove rrd data manually in /var/lib/rrd/ directory.
