[monit] RE: problem with monitoring apache

[pavel . stratil-jun]

Thank you for your tips, but nothing helped. To your questions

> So I don't have the line you have, 'request "monit"' - is this needed?
> What does it give you over my lines?

the request directive tells monit to request a "path" on the host you are
connecting to. so 'request "monit"' tells in my case monit to look for
http://localhost:80/monit  ... i tried omitting the directive but that
didnt help.

naturally, that was the first thing i tried... while wget and tellnet
resolve the ip correctly monit might have had some problems with it.
unfortunatelly, this was not the case.

any other tips will be quite appreciated.
