The Plesk Web Server service on host as.xxxxx.com is down.

[Justin Clarke]

thanks Justin, I am going to check that out... err just have to make sometime!

No problem, it's pretty good I think. I'm temporarily just running it with "alert" rather than the "restart" commands for the tutorials config file. Also I commented out this bit:

# set httpd port 2812 and
# SSL ENABLE
# PEMFILE /var/certs/monit.pem
# allow admin:test

And didn't do the certificates bit as these lines seemed to cause Monit to crash once started. Maybe I'll look into that another day.

Need to figure out how to monitor the Plesk Web Service (sw-cp-serverd), once I've done that I'll post my config file which may help others.

Hey Justin, did you use any HOWTO docs or did you just go through Munin and Monit documentation?

Hey Justin, did you use any HOWTO docs or did you just go through Munin and Monit documentation?

I just used http://www.howtoforge.com/server-monitoring-with-munin-and-monit-on-centos-5.2-p2 and then the Monit documentation to get it working.

I have a small issue with the MySQL monitor as each time Monit is stopped/started it says that MySQl has failed. This means I can't have that on a "restart" otherwise it crashes MySQL. So that has to be on an "alert" only.

I'll paste in my config file tomorrow (if I remember!).

It's not complete, but monitors the major services. Works nicely so far.

Tried to add sw-cp-serverd but can't figure out how yet! Also the imapd-ssl doesn't exist.
