Asterisk Test Calls?

[MTWiley]

I think this might be getting to be a bit too specific to asterisk to get hekp on the Zabbix forums, but I thought I'd ask anyways. We'd like to be able to make a test call every 10 minutes and be notified if the call fails. We're already monitoring Asterisk with Zabbix by checking the number of sip and iax2 trunks as well as monitoring the number of active calls using the following.

UserParameter=sudo asterisk -rvvvvvx 'sip show registry'|grep Registered |wc -l
UserParameter=sudo asterisk -rvvvvvx 'iax2 show registry'|grep Registered |wc -l
UserParameter=sudo asterisk -rvvvvvx 'core show channels'|grep --text -i 'active call'|awk '{print $1}'

Does anyone know of a way to accomplish making an outside call and setting off a trigger if the call is unsuccessful?

You may need to use a combination of cron, an external script, zabbix sender and nodata(900).

Have cron kick off a script which will perform a test call, and report it's success/failure. It will then use zabbix_sender to push the data to the Zabbix server. On the Zabbix server you can trigger if you have no data for 15 minutes (nodata(900)), or if the last result is whatever you designate to be your error code.

Okay, I've done a bit more, but I'm kind of stuck. I wrote put together the following script from bits and pieces that I've found.

#!/bin/bash

DATE=`date +%d%m%Y-%H%M`
FILENAME="$DATE".call

echo "Channel: Local/1234567890@from-internal" >> /tmp/$FILENAME
echo "Application: Playback" >> /tmp/$FILENAME
echo "Data: hello-world" >> /tmp/$FILENAME
echo "MaxRetries: 2" >> /tmp/$FILENAME
echo "RetryTime: 30" >> /tmp/$FILENAME
echo "Priority: 1" >> /tmp/$FILENAME
echo "Archive: Yes" >> /tmp/$FILENAME
# This line only works when running as root. Using chmod instead as a workaround.
# chown asterisk:asterisk /tmp/$FILENAME
chmod 777 /tmp/$FILENAME
mv /tmp/$FILENAME /var/spool/asterisk/outgoing/
sleep 10
cat /var/spool/asterisk/outgoing_done/$FILENAME |grep Status:|awk '{print $2}'

The script successfully calls an outside number and returns either Success, Expired or Failure, depending on whether or not the test call went through.

I tried adding this script to the UserParameters, unfortunately it just instantly returns ZBX_NOTSUPPORTED. I've been rereading your advice and it mentioned the zabbix_sender but I can't seem to figure out how to run the zabbix_sender in linux. I've done it in windows, but I either didn't install it or just keep looking in the wrong place. Would you be able to help point me in the right direction of where it should be? I've checked /usr/local/bin/zabbix_sender & /usr/local/sbin/zabbix_sender with no luck, is it someplace else by default? or is it maybe something that I have to explicitly install?

Update:

I got it working. I added to the script and here's the final version, I just made it an active check and run it via cron every 10 minutes.

#!/bin/bash

DATE=`date +%d%m%Y-%H%M`
FILENAME="$DATE".call

echo "Channel: Local/1234567890@from-internal" >> /tmp/$FILENAME
echo "Application: Playback" >> /tmp/$FILENAME
echo "Data: hello-world" >> /tmp/$FILENAME
echo "MaxRetries: 2" >> /tmp/$FILENAME
echo "RetryTime: 30" >> /tmp/$FILENAME
echo "Priority: 1" >> /tmp/$FILENAME
echo "Archive: Yes" >> /tmp/$FILENAME
chmod 777 /tmp/$FILENAME
mv /tmp/$FILENAME /var/spool/asterisk/outgoing/
sleep 10
STATUS=`cat /var/spool/asterisk/outgoing_done/$FILENAME |grep Status:|awk '{print $2}'`
/etc/zabbix/./zabbix_sender -z [zabbix server ip address] -p [zabbix server port(default 10051)] -s [monitored host name] -k [key] -o $STATUS
rm /var/spool/asterisk/outgoing_done/$FILENAME

Hopefully somebody else will find this if they're ever looking to setup a similar outbound test call.
