Dear Sir,

I am writing to thank you for your letter and say,

A day was probably excessive. With the right planning and forethought
(as another correspondent mentioned, using the config conversion tools
is definitely worthwhile. Don't take my word for it; that's what Mr
Galstad said in the FAQ) this should be possible in much less.

That sounds like a very good low risk idea.

Don't put it off though. Nagios is more than a different name and a
slightly different look; there are definite and useful improvements.

Among the Nagios plusses,

+ precise and unvarying scheduling.

My checks that also update an RRD, once scheduled for a 5 minute
boundary, continue to be run on that boundary.

This was not so with Netsaint.

+ much faster response to command queue events such as en/disabling
checks or notifications

Netsaint seemed to take 30-90 seconds to responsd to requests, but
Nagios takes less than 30.

Yours sincerely.
