'Current load' flood

[niiiro]

Hey All,

I'm using Nagios v3.3.1 linked to 15 Linux clients.

I'm having an issue while one of the client servers, receives a warning regarding 'Current Load' service - I get emails from ALL clients as they were part of the problem also. which means, instead of getting 1 email from Client1 ONLY, I get 15 emails.

Would appreciate your help.


Regards,

Nir.

I'm not quite sure what you mean by "linked," would you mind elaborating a little bit? Do you just mean that you are running checks against them? Are any of them dependent on the others?

Thanks for your reply, agriffin.

Yes, My meaning was that I just run checks on various clients. none of them are depended on each other but yet, whenever one of them happens to get 'Current Load' warning - I get emails from all clients. as they were part of the problem as well.

I'm not sure what could cause this. Would you mind posting your service definitions?

Sure.

This is Nagios's server .cfg file - localhost.cfg
