Re: Is this a bug with dependent services?

[Alexey Zilber]

Hi Martin,

   The following seems to work ok:

check process apache
        with pidfile /var/run/httpd.pid
        start program = "/etc/init.d/httpd start"
        stop program  = "/etc/init.d/httpd stop"
        if failed host 192.168.1.25 port 80 for 3 times within 5 cycles then exec "/usr/lib/heartbeat/hb_standby"
        if failed host 192.168.1.26
 port 80 for 3 times within 5 cycles then exec "/usr/lib/heartbeat/hb_standby"
        mode manual
group node2


I just merged the 2 checks into the main config.  Also, and this is probably for another thread, the monit+heartbeat configuration seems to be wrong.  That plus a logging bug in heartbeat's ResourceManager had me stumped for a few days.  I'll write up a doc on it in a bit.. once I confirm the config is works properly and is stable.

Thanks!
Alex

Monit currently doesn't prevent the dependants from starting - the
current dependency chain just ensures correct startup sequence.

We plan to improve it in the future.
