Systems Up Macro

The systems_up_alarms_macros.cfg is a script macro for reporting when down systems revive (come back up).

systems_up(SYS)
 
        init
                status =piktstatus
                level =piktlevel
                task "Report revived down systems"
                input proc "(SYS)"
                dat $host 1
#ifdef debug
        rule
                output $host
#endifdef

        rule    // initialize up message
                set $upmsg = "$host is (back) up"

        rule    // initialize the state
                set $state = "+"

        rule    // ping the host
                // do the initial poll quickly
                if =pingfail($host, 1, 1)
                        // if the first ping failed, try again with more
                        // retries and longer timeouts
                        if =pingfail($host, 3, 5)
                                set $state = "-"
                        fi
                fi

        rule
                if $state eq "+"
                        output mail $upmsg
                fi

You might invoke the =systems_up() macro in your alarms.cfg file thusly:

#if piktmaster
 
SysUp
        =systems_up(=piktc -L +H down)

#endif

where 'down' is a host group of known down systems (specified in down_systems.cfg).

You might invoke the SysUp script in, for example, a PiktAdminInfo alarm group (specified in alerts.cfg) as a periodic reminder to remove revived systems from the down_systems.cfg #include file.

Output from this script might look like, for example:

INFO:
    SysUp
        Report revived down systems

        budapest is (back) up
        kiev is (back) up
        hotspare is (back) up
