Finally! PNP 0.4.3 as Debian package! And Nagios 3.0beta5... Did you download Nagios 3.0b4?? Doesn't matter, download and install 3.0 Beta 5 To get your performance data in RRDs and watch the wonderful graphs exported from RRDs get PNP (PNP is Not Perfparse). Have a look at README.Debian to start process performance data. See you at NETWAYS Nagios Konferenz!
