Nagios Support Forum

Hi Team,

We are getting false alarm, means hosts up but its showing down in nagiosxi all services are in OK status, but host is critical, when i was able to ping systems its pinging.

Do we have any false alarm detection mechanism for rectifying actual and false alarm. or any other way for it?

The unfortunate thing about false alarms is that they are "false" alarms. Instead of trying to validate a false alarm I would look at why the check thought it was false in the first place. Can you show us the output of the check in the XI interface?

Hi tmcdonald,

Thanks for your reply,
We are getting ping and ping6 error, please check the error attached in screenshots.

error: "/bin/ping6 -n -U -w 10 -c 1 localhost"

Go to your CCM and find one of the misbehaving services in the Services list, then on the right click the icon for "View Config" and post it here, being sure to hide any sensitive info.

Hi tmcdonald,

Go to your CCM and find one of the misbehaving services

sorry, but i am not getting clearily, can you just elaborate this ones.

In XI, go to Configure, then click Core Config Manager. Type the name of your service in the search box and click the diskette icon, as indicated in the picture.

Hi tmcdonald,

As we are getting issue in hosts response. its showing ping and ping6 error. hosts showing "down" but services working fine.

some host are in critical from last couple of days but services of that host is OK, when we are pinging that host its pinging.

Yes we understand that, we still need to see what tmcdonald asked for. Thank you. All you need to do is go into the hosts section instead of the services, you will notice the options and directions are absolutely the same.

hi slansing,

thank you very much.

please check the output of diskette.

Is there a reason you have this set up as a passive host? You will want to make this an active host if you are trying to ping. Going back through the wizard you should be able to make this an active. Being passive, Nagios is waiting for a reply from the remote host instead of initiating itself.
