Nagios Support Forum

I am looking for a procedure to edit a host (switch) name and IP. I have looked in Host Groups under "Add a new comment" which gives an option to edit the host name, althouugh I dont have permissions as of this instance, but is this where you would edit the host name. Secondly, I am searching how to update the IP so Nagios can log the new switch changes. I have went into the switch and configured for NAgios to recieve logging although it was already configured prior to new switch changes. I am using Nagios Core Version 4.0.4

Thanks.

To change these settings you'll need to locate the configuration file for that host definition. Do you know what file it's stored in?

The tree folder should start at /usr/local/nagios/etc/ for configuration files.

No I do not, this will be my first attempt at getting into the linux server Nagios is running on to make the changes needed.

No I do not know exactly where the file is stored on the Linux server, but I will be making an attempt to go in and make a change. I will start with the tree folder you suggested.

Ok so, I did find the files and I did change the IP and Host name and saved. I than did a program restart and now I am receiving: Whoops! Error: Could not read host and service status information!

Any ideas?

What did you restart?

You should restart the nagios service and the http service.

i restarted nagios services under system>processinfo> in the gui. I than tried your commands and i got a no such service for the httpd command and a Job for nagios.service failed.

What OS are you running this on?

Try this:
I would like to see the output of what happens when you attempt to restart nagios.

linux

i made the changes in the .cfg file where the host is located, do i need to compile the new change?
