[Nagiosplug-devel] Please can I have GIT access

OK: now 2 ways of storing the state info.

Could you please point me at examples of the 2 techniques below.

Can I assume that either would be perfectly acceptable ?

This does seem much more complicated than just giving a file name, more difficult
for an end user to set up. It is also RAM kept permanently in use, whereas
with a file - it is opened once every 5 minutes.

Why do you consider this superior to using a file ? After all nagios itself
uses a status.dat file to store state info.
I don't understand.

I can't see that....
