asterisk users - Oct 2003 - monitoring the asterisk and safe restart

Hi List,

I am sorry that I may bring the old question to the community. My question
is
1. How can we determine if asterisk is working normally or not ? what kind
watchdog process do we have at this moment ?

2. In case the running asterisk is mulfucntion, is there any available way
to auto restart asterisk ??

Please advise if you could.

Thanks.

Off the top of my head maybe something like this?


while(1)
  asterisk
  wait `cat /var/run/astrisk.pid`
  sleep 1
end

Looking at the above it could be improved, like checking
for the /var/run/astrisk.pid file before the wait and 
bailing out if not found.

I've never used it, but this sounds a lot like what the safe_asterisk 
script does...

/usr/sbin/safe_asterisk
/usr/src/asterisk/safe_asterisk

I use daemontools ( http://cr.yp.to/daemontools.html ). 

Here, for instance, is my '/service/asterisk/run' script.  You only need
the
first uncommented line and the last uncommented line. You can ignore all of 
the networking stuff, but I wanted to know, if anyone else happened to see 
this, if  someone knew if zaptel's PPP device can use authenticated PPP 
(PAP/CHAT) in this case.  I had to get a special setup from my ISP to get a 
frame without PAP authentication.

/service/asterisk/run:
#!/bin/bash
#
#  Script to unload and reload asterisk and related networking functions
#

# Direct stderr to stdout so daemontools logger puts it all in log/main
exec 2>&1 

# Bring down network connections so ztcfg can run
ifconfig pvc0 down
ifconfig hdlc0 down
ifconfig hdlc1 down
ifconfig hdlc2 down
/etc/init.d/monmotha stop
/etc/init.d/monmotha zap

# Remove modules
rmmod wcfxs wcfxo tor2 zaptel

# Reload modules
modprobe tor2
modprobe wcfxo
modprobe wcfxs
sleep 3   # wcfxo doesn't like things too fast, so wait 3 sec

# Configure WAN cards
ztcfg -vvvv
sleep 3   # wcfxo doesn't like things too fast, so wait 3 sec
#
## Configure Frame to ISP
sethdlc hdlc0 mode fr-ansi create 16
ifconfig hdlc0 up
ifconfig pvc0 <local public ip> pointopoint <gateway ip> up

sethdlc hdlc1 mode hdlc
ifconfig hdlc1 192.168.1.1 pointopoint 192.168.1.2 up
