Can this be possible?

[hqin]

We have about 10 hosts that were configured in Nagios XI. now we need to send alerts whenever there are more than 5 hosts down. In other cases, for example, 3 of them are down, we don't need Nagios XI to send alerts to us. Can it be possible in Nagios XI?

Thanks

This is not built in to Nagios XI directly, but it shouldn't be incredibly hard to write a plugin for. Basically:

- Disable alerts for those hosts
- Write a plugin that checks to number of down hosts
- Alert off that one host

The drawback to this is that you would get one alert for that meta-service, instead of having it enable alerts for the rest. You could probably get around this with external commands using ENABLE_NOTIFICATIONS.

The BPI (business process intelligence) component may be useful for this one too.

Just goto Home -> Nagios BPI to check it out.

Here's a doc:

Great, let us know, it can get complicated.

the zip file looks outdated and doesn't work after installed in Nagios XI - some files are missing. However, I searched this forum and found this http://support.nagios.com/forum/viewtop ... .sh#p59516. I downloaded the updated zip file provided in this post and it works finally. Thanks everyone.

Glad you got it working, and thanks again to 455157 for the suggestion!
