Asterisk Alerts On Zabbix

Good Day

i hope i`m on the correct forum i have been given a task to setup an monitoring system on zabbix for asterisk to minitor if more than one asterisk is running and so far i manage to check for only one process
UserParameter=ae.asterisk.running, sudo ps -ef | grep /usr/sbin/asterisk | grep -v grep | wc -l

now i need to be able to get an alert if more than 1 asterisk is running

If You count the instances by wc -l Your alarm would be UserParameter > 1. For examples just consult the zabbix-documentation.
