I read the your other post first, and didn't realize that you were actually answering my question with a question here.
'What do want nagios to alert you of?' - A file mesg has come through
We've thought of a couple of ways to do this... either can Nagios watch each file coming through on a pipe? (file size, name)
Or these files are stored into a directory, and Nagios is watching a directory, and reports via email on the directory about every file when it arrives?
My supervisor wrote it this way which doesn't make a lot of sense: "transport monitoring for HTTPS/SSL and VPN file transport with examples of a remotely accessible UI serving 200+ client sites."
"don't post in multiple sections" - Not knowing where to post... Whether it is a plugin I need, or not. What would you have done in my situation?
