Munin & Monit

[nenad]

Hi,

is it possible to increase timeout for http protocol from 5 to 15 sec.?

check process apache with pidfile /var/run/apache2.pid
   group www
   start program = "/etc/init.d/apache2 start"
   stop program  = "/etc/init.d/apache2 stop"
   if failed host www.web-hosting.co.yu port 80 protocol http
        and request "/monit/token" then restart
   if cpu is greater than 60% for 2 cycles then alert
   if cpu > 80% for 10 cycles then restart
   if totalmem > 500 MB for 5 cycles then restart
   if children > 250 then restart
   if loadavg(5min) greater than 10 for 8 cycles then stop
   if 3 restarts within 5 cycles then timeout

and is it possible to check apache localy without testing it through web acess ?
sometimes, internet connection where my server resides is under heavy load, so timeouts could be bigger than 5 sec. , and it causes unnecesery resrtarts of apache...

Yes, use

check process apache with pidfile /var/run/apache2.pid
   group www
   start program = "/etc/init.d/apache2 start"
   stop program  = "/etc/init.d/apache2 stop"
   if failed host 127.0.0.1 port 80 protocol http
        and request "/monit/token" then restart
   if cpu is greater than 60% for 2 cycles then alert
   if cpu > 80% for 10 cycles then restart
   if totalmem > 500 MB for 5 cycles then restart
   if children > 250 then restart
   if loadavg(5min) greater than 10 for 8 cycles then stop
   if 3 restarts within 5 cycles then timeout

then, but make sure that monit/token is in that webspace then.

Port: If failed 127.0.0.1:80 [DEFAULT] with timeout 5 seconds then restart else if recovered then alert

That timeout. I guess it is port timeout.


Isn't it enough just to use

if failed host 127.0.0.1 port 80 then restart

What's in /etc/default/monit?

You can do that if you like.

I'm not quite sure how to change that, but you can have a look here: http://www.tildeslash.com/monit/doc/

I've followed the howto, but I can not get munin to display the apache stats,

When I run the plugin directly I get,

Can't locate object method "new" via package "LWP::UserAgent" at ./apache_accesses line 128.

Has anyone managed to get the apache stats to display?

Cheers
