Need help with monitoring a log

We have created a processor log that keeps a snapshot in 5 minute increments, this data is both number of processes as well as total CPU Utilization (By %)…

So, what I want to know is how I can set up a monitor in Nagios that would tell us when we went above a specific threashold.

Or would it be better to just watch the Processes and utilization in Nagios directly, if this is the better solution then how would one go about configuring this?

Thank you for your time!!!

check_procs and check_load already do it.

Execute the plugins with --help for more info.
