Counter Group Settings
You can :
-
Edit settings such as bucket size and other settings
-
Edit topper policies: how many toppers to track for each meter
-
Perform further configuration for user defined counter groups
You can also enable or disable any counter group.
Restart is required since changes will be made effective only upon restarting Trisul
Disabling a built-in counter group will cause all user-defined counter groups that depend on it to report zero usage.
