Re: [monit] Question about multi-host testing

[Pablo Iranzo Gómez]

        Martin, 

        I've did this one before writing to the list, but failed, so that was
the reason:

check host ro5000-gkgRn17229AEBsh17232 with address 10.39.16.1
        if failed ICMP type ECHO count 1 timeout 10 seconds then alert
        alert address@hidden with reminder on 1 cycle

check host pos10.5000-gkgRn17229AEBsh17232 with address 10.39.16.10
        if failed ICMP type ECHO count 1 timeout 10 seconds then alert
        depends on ro5000-gkgRn17229AEBsh17232
        alert address@hidden with reminder on 1 cycle

        The "gkgRn17229AEBsh17232" is just to ensure that there are no service
name duplicates, what I'm getting is two email alerts

        If I just put "if failed icmp then alert" monit complains about
configuration (I'm using monit-4.9-1), so either I'm doing something
wrong or it's a problem with this verson.

        Thanks in advance
        Pablo
