Recommendations for reactive monitoring

[nathanc]

Hey guys,
Just see if there is a recommendation for reactive monitoring. Ive used monit in the past for monitoring Mongrel webservers. Is there a preferred programs that can make sure that litespeed is always happy and healthy?

You can use our caccti integration, tutorial is in our wiki.

ah yes cacti. Ive been using it for a week now to graph my litespeed servers. but cacti ,correct me if im wrong, does not react, if a litespeed server goes down. Cacti is simply there to graph. Can cacti react if a litespeed server goes down?

LSWS has built-in watch dog process, unless there are hardware problem or mis-configuration, LSWS will never go down.

run "/opt/lsws/bin/lswsctrl reload" five times fast.
Thats crashes my litespeed servers everytime. They do not comeback on their own. I have to manually issue "/opt/lsws/bin/lswsctrl start".

How often do you need to restart LSWS five times in a row within 5 seconds period? Why do you need to do that?
It could be a problem if all rails applications are set to "run on startup", so you got 20 rails frameworks to be initialized at start up.

We probably will add a feature to let user to restart each individual application instead of starting the whole server.
We could do something to make it run smoother.
