[monit] Can't use hb_standby in monit

[Vianney Lejeune]

Hello,

	I really don't understand why it doesn't work. I tried many  
tutorials, read and reread the manual but I'm always unable to do  
something, this is a sample of my monitrc file:

=======
check process apache2_webserver with pidfile /var/run/apache2.pid
   depends on mysql_DBserver, heartbeat
   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 for 4 times within  
4 cycles then exec "/usr/lib/heartbeat/hb_standby"
   group wwwdata
   mode manual
=====

I know that hb_standby works, but I'm unable to trigger anything with  
this configuration, I replaced " exec "/usr/lib/heartbeat/hb_standby"  
" by unmonitor, timeout and so. Nothing is triggered. I'm just looking  
for a working configuration using the hb_standby based on a connection  
test, I wonder if something isn't wrong with monit on my system.

Regards,
Vianney
