Remote Server Check Overkill?

[AWS]

Hi!

I'm currently monitoring two remote servers with checks every 5 minutes. Am I doing an overkill? I'm checking 43 remote services spread across two servers in two different geographical locations. I've been watching the CPU usage on both the local Nagios server and the remote servers and I don't *think* I'm generatering too many CPU cycles but what is the "norm" - if there is one? What do other people use for the monitoring frequency checks? When I get more servers to monitor, will I need to tone that down some?

I've not measured it before but I don't think the bandwidth usage is too much either? I don't see spikes of "large data" so I also think I'm not flooding their/my connection.

Here is a cut-n-paste of the Nagios stats currently on my system. I'm not sure what "normal" is so I don't know what to compare any of these stats to.

Thoughts? Feedback?

Thanks.

5 minutes is generally considered the norm, but keep in mind you can use whatever values you need. If the services aren't super high priority, you can set them for however often you want to check them. But once again, 5 minutes is the default and the norm.
