Nagios Support Forum

how do i add or generate new template for performance graph? right now all my services are using default template.

This is a feature of PNP. Although we package and ship PNP as part of our product the best I can do for support is direct you to the PNP documentation.

I'm sure you can do whatever you wanted using extended service configuration as described else where on the forums, for providing limited access for users to acknowledge alters.
