Hi all. I didn’t see a way to send alerts like this, so I did a little research and wrote an ‘amateur’ script to send out alerts for me. I’m sure this could be much improved, but it serves my purposes right now. Basically, it just sends out info from the log, and could be modified to trigger on anything you can grep from any log. I stuck this in my crontab (run crontab -e) to get it running every minute (without sending mail to root):
* * * * * /usr/bin/unreachable.sh > /dev/null 2>&1
Hopefully my efforts can help someone out, or spur some community development. This could use some betterment; like right now it sends nightly blank emails when the log rolls over, the email itself lacks formatted content so I could modify the ‘mail’ statement and make the output better, etc.
#!/bin/bash
touch /tmp/newunreachable
touch /tmp/oldunreachable
cat /var/log/asterisk/full | grep "is now" > /tmp/newunreachable
send=$(diff /tmp/newunreachable /tmp/oldunreachable)
if [ -n "$send" ]
then
cat /tmp/newunreachable | mail -s "Connected peers changed" -r asterisk [email protected]
logger "Found connected peer changes."
fi
\cp /tmp/newunreachable /tmp/oldunreachable
