Nagios Support Forum

tried it still not working...Will rebuild take a long time to complete?

Depends on the size of your installation and how customized it was as well.

Do I need to remove Nagios first then reinstall? or just stop services is good enough?

A rebuild is best done on a fresh system. That said, have you considered contacting us for a quickstart ( 1 hour remote session with phone support)? It is a free, one time offer for those evaluating the product. We may be able to fix this issue and get your eval moving again without a full reinstall.

This phone support is great! I'll be available tomorrow after 9am. In the meantime I'll see if I can fix it and let you know by 5pm this afternoon. Thank you so much!

I'm trying to reinstall Nagios and I'm stuck here in the installation pdf:

Nagios Core Installation
tar zxvf nagios-4.0.2.tar.gz <== fine
tar zxvf nagios-plugins-1.5.tar.gz <== fine
Change to the new Nagios directory and install the packages:
cd nagios <== It says directory not found.

That is nagios core, not XI. XI does not use core 4 yet. You should use the XI installer. Follow the doc:
http://assets.nagios.com/downloads/nagi ... ctions.pdf
Do note that this installation assume a clean, minimal install of centos or redhat. Alternatively, we can try to solve your current XI problems in the quickstart tomorrow.

We had re-installed NagiosXI on a clean RHEL 5 successfully. However we got a different error message when applying configuration. Here's the error log:

***> One or more problems was encountered while processing the config files...

Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.

Error: Invalid max_check_attempts value for host 'AL5CMSCH01'

Go to the CCM and view the host 'AL5CMSCH01'. Check to see if max_check_attempts is valid, typically a single positive integer.

YES that fixed the issue! How come it is not shown as a required field but it is required?
