Nagios – Change date format

Hello everyone, today a customer asked me to change the default date format for the Nagios web interface since he wanted an international date format instead of the default us date format. I thought I should share the procedure so here is how to do it (I did this on Ubuntu 14.04.2):

This is how the web interface looked before:


Ok. First open the nagios.cfg file by running the following command:

sudo nano /usr/local/nagios/etc/nagios.cfg


Next search for “date_format” and change it from:




Save and then restart the Nagios service by running:

sudo service nagios restart

After the Nagios service has successfully restarted your web interface will look like this:


Well, that´s it. Now all dates will be displayed in the international ISO8601 date format on your Nagios web interface. (Btw this does not change the log file format.)

I hope you liked my today´s post and I hope to see you again next time 🙂
