This is a simple perl script that parses /var/log/nagios/status.dat and prints how long execution of each service type took. Useful for performance tuning. THIS IS NOT A PLUGIN - it is a console utility.
This is a simple perl script that parses /var/log/nagios/status.dat and prints how long execution of each service type took sorting data by time - it both prints each individual service took on top and on the button in reverse order consolidates services with same names but on different hosts so you get an idea of data for this service on average.

This is useful for performance tuning to find which plugins and checks are executing too long. Just run it and see what it does.

Worked as described.

Just replaced the below line with the actual one.

#my $file="/var/log/nagios/status.dat"; - old line
my $file="/usr/local/nagios/var/status.dat"; - new line

Run the file & export all data into a text file using ">" sign.
A must-have to find out nagios controls perf issues. Thanks a lot for your contribution William Leibzon!!!!

For my NagiosXI, I only had to change the variable:

my $file="/var/log/nagios/status.dat";


my $file="/usr/local/nagios/var/status.dat";

And worked like a charm. My NagiosXI version is:

Nagios XI (5.4.4)

Seems like a very useful script but getting the following exception. Do you have fix

Illegal division by zero at ./profile_nagios_executiontime.pl line 49.
