Setting Nagios warning and critical load threshold?

Hii everyone.

I am here with a new query hoping linux gurus can help me.

we have server that was cloned from physical to virtual. Now the load on this server has tremendously reduced. But the threshold set are w.r.t physical server and we do not receive any alert for load as the increased load always falls below previously set threshold.

Now I need to set the warning and critical threshold w.r.t virtual server.

I created a cronjob to record a load on server every 5 mins. Now after couple of weeks I got a load average with 1000s of samples.

Can someone help me with how can I set warning and critical threshold with the help of these load samples?

btw, the server has only one core.

Following is the file containing the samples. Open it with Wordpad or MSWord.

NAME
Nagios - network/systems status monitoring daemon SYNOPSIS
nagios [-h] [-v] [-s] [-d] <main_config_file> DESCRIPTION
nagios is a daemon program that monitors the status of various network accessible systems, devices, and more. For more information, please consult the online documentation available at http://www.nagios.org, or on your nagios server's web page. OPTIONS
main_config_file The main configuration file. On openSUSE systems this defaults to /etc/nagios/nagios.cfg -h A helpful usage message -v Reads all data in the configuration files and performs a basic verification/sanity check. Always make sure you verify your config data before (re)starting Nagios. You can also use the Nagios init script to verify your configuration - try: rcnagios check_verbose -s Shows projected/recommended check scheduling information based on the current data in the configuration files. -d Starts Nagios in daemon mode (instead of as a foreground process).
