Host Status not correct

[QS1]

Hello,

I have two hosts that show as being down ... Yet, all of their services are up and Ok.

Please see attached screenshot:

Any suggestions?


Thanks

Is your host not accepting ping? Thats a common cause of that problem.

[QS1]

That is correct ... We have ping traffic blocked.

What would probably be best in your situation, since there are so few that are are not accepting ping, is to edit the host directly.

I just wrote up a doc that specifically addresses your need.

Ok - I have edited the hosts and templates as needed. I have applied configuration but they are still showing down. Is there a way to reset the hosts for the changes to take place?

[nscott]

Well, if you just did it, I would give it the length of how long you have between checks.

After doing that and it still not working, I would verify the check that you specified will work and is properly set by running the very check you specified on the command line. That will be a good start.

I can't seem to find out exactly how to do that ... I know you can run it manually from the server.

Can you point me in the right direction?

Here's an excerpt from this document:

It's useful to be familiar with running your plugins from the command line, for both informational and debugging purposes. They are located in the /usr/local/nagios/libexec directory. Navigate to that directory and run your plugin with the following commands:

Code: Select all

# cd /usr/local/nagios/libexec
# ./plugin_name args...

Experiment a bit and figure out the best way to run the plugin. It probably has a help option you can use to learn more:

Code: Select all

# ./plugin_name -h

Here's an example:

Code: Select all

# ./check_icmp -H localhost
OK - localhost: rta 0.016ms, lost 0%|rta=0.016ms;200.000;500.000;0; pl=0%;40;80;;

To find out the exact arguments that Nagios is using, you can look at the command definition in the Core Config Manager.

Thanks all ... it works ... I changed it to look at the status of nagios client service.

Good deal, glad it's working for you!
