Email notification if the status of an extension is "UNKNOWN"

[Csaba (Galyas Csaba)]

I found a solution in previous posts, but unfortunately not worked for me:

[HOW-TO] Use shell script to monitor extension status and get email notification

I have a script to check if an extension is up and it run on cron job every 30 minutes. Any thoughts on how to make the script send an email once and not every 30 minutes while the extension is down? #!/bin/bash email="[email protected]" A=`/usr/sbin/asterisk -x 'sip show peer 200' | grep -i status | cut -d' ' -f11` if [ "$A" != "OK" ]; then ( echo "Subject: Extension 200 is down" printf 'Extension 200 is down"...' ) | /usr/sbin/sendmail ${email} fi

-I created a file: /usr/13.sh
-It has this:

#!/bin/bash
email="[email protected]"
A=/usr/sbin/asterisk -x 'sip show peer 13' | grep -i status | cut -d' ' -f11
if [ “$A” != “OK” ]; then
(
echo “Subject: Extension 13 is down”
printf ‘Extension 13 is down"…’
) | /usr/sbin/sendmail ${email}
fi

If I run 13.sh, I don’t get any emails, even though the status of extension 13 is “UNKNOWN”.
What could be wrong?

In this thread I suggest a synchronous method over the asynchronous cron method

[SOLVED] Fail2ban email - custom

Fail2ban is probably the wrong tool for the job, it’s regex’s are optimized to extract IP addresses from log files, and conditionally add them to iptables. But similar behavior can be achieved very simply from bash tail -F /var/log/asterisk/full|while read i;do if [[ $i =~ “UNREACHABLE” ]];then echo $i|mail [email protected] ;fi;done & make your version of “unreachable” be a regex that matches exactly what you get when your trunk disappears, add that line to /etc/rc.local , you can easily…
