Hi, Nathan.

- From the point of processing performance numbers I can't help you, but I
can offer my situation. I used to run a lot of SNMP checks, but every
now and again I would get bottlenecks with bandwidth. This would then
cause the checks to timeout and fail.

I switched to using NRPE and I haven't had any issue like that since.
Checks seem to be done much faster. This is my experience using it in
regards to limited, or constrained, bandwidth across networks. I do both
CPU load and disk space checks and definitely prefer the disk check
across NRPE.

Regards,
Max
