Thanks Ralf,
Mon now calls the alert.reboot program :)
all i changed was the period line.
The problem i have now is working out what the status is of the system,
the way i understood the man pages, there should be a varable avilable to the alert
program e.g. $MON_ALERTTYPE which is set to 'failure' or 'up' to signify what the
alert is about
i have :
if ($MON_ALERTTYPE == 'failure') {
system("/sbin/shutdown -r 1");
}
i have in the alert script :
print <<EOF;
This happened on $wday $mon $day $tm
Summary information: $summary
Arguments passed to this script: @ARGV
Alert Type: $MON_ALERTTYPE
Detailed information follows:
EOF
this shows NOTHING for the contents of $MON_ALERTTYPE
Am i using the wrong var, or am i missing some other setting?
(full script at end of post)
Thanks
Matt Lowe
