[Asterisk-Users] Polling Asterisk for Life

[David Cook]

Obviously if Asterisk keeps going down there is another problem to be 
found. However, why not start it from /etc/inittab with respawn??? Else, 
poll from cron or a script with ps ax | grep asterisk | grep -v grep | 
wc -l to find out if it is running. dbc. Date: Thu, 2 Mar 2006 22:01:01

text/plain; charset="us-ascii" AFAIK there are problems with repeatedly 
connecting and disconnecting the manager interface. Also you're probably 
using a proxy (all "manager" interfaces I've seen are using proxies), it 
might not be a good idea to pool something out of the manager that 
often. Did you consider running a "cron" job on the server, using 
"asterisk -rx" to run a command and then decide rather asterisk is down 
or not based on the result? This way you'd be doing on the server, 
working around the problems with the manager interface and saving some 
bandwidth :) . You might also be able to call /sbin/reboot directly from 
the cron script! If on the other hand the whole server is going down you 
may simply use ping!
