nagios and rrdtool. (to create those nice graphs
Currently there's a nice project called apan, but it doesn't intergrate
nicely with nagios. (you'll have to do a some things double, configure a
lot of complicated stuff etc.)
I purpose the following method to add performance data graphs to nagios:
A generic way to let the current plugins return performance data that
nagios can store in rrdtool. This way it wouldn't matter if i use
check_disk with nrpe, or nagios_statd, or any other method. The current
plugins only need a slight modification to return the data in some generic
format. Perhaps we can add a "field" to the current returned data and let
plugins return something like:
DISK OK - [1000000 kB (10%) free on /dev/sda1]
curr=9000000,max=10000000
So we add a new line with performance data thats easy to interpret and is
formatted in a generic way. So "curr" is always the current value of
a service, and "max" always will be the maximum value.
What do you think of this? Any suggestions for this system, or should we
just do it and submit our patches?
