tldr; I would like to show a list of the ten slowest Apache requests within the past 24 hours.
I can modify Apache to include in a custom log the time to required to serve the request and I can also write a shell script to retrieve the ten slowest entries within a defined time interval. The output can be passed on to Nagios via NRPE.
Once Nagios has received it, is there a plugin that allows Nagios to display it as a list? Alternatively, an HTML style table or embedded faux spreadsheet also works.
