Re: [asterisk-users] Which tool to automatically restart Asterisk ?
Sorry , I forget it for another monitoring tool monit that we have used in our production systems to restart asterisk in case of asterisk crash or halt. I have attached a monit configuration for your reference. it will work almost in all cases This configuration will check Asterisk for following 1. will check for Asterisk process. 2. will check Asterisk via AMI 3. will check Asterisk by sending a SIP request You simply need to install monit and place attached file on your server as /etc/monit.d/asterisk.conf and then restart monit service daemon *Tahir Almas* Managing Partner ICT Innovations http://www.ictbroadcast.com http://www.ictinnovations.com Leveraging open source in ICT On Thu, Feb 23, 2017 at 3:45 PM, Olivier wrote: > > > 2017-02-21 14:09 GMT+01:00 Tahir Almas : > >> Why not to use Fail2ban https://www.voip-info.org/wiki >> /view/Fail2Ban+%28with+iptables%29+And+Asterisk >> >> How would fail2ban detect that Asterisk needs to be restarted ? > > >> >> >> *Tahir Almas* >> >> Managing Partner >> ICT Innovations >> http://www.ictinnovations.com >> http://www.ictbroadcast.com >> Leveraging open source in ICT >> >> >> >> On Tue, Feb 21, 2017 at 12:28 AM, Tzafrir Cohen > > wrote: >> >>> On Mon, Feb 20, 2017 at 11:36:24AM -0300, Victor Villarreal wrote: >>> > Hi, Oliver. >>> > >>> > Maybe something like this (add this script to your crontab): >>> > >>> > 8<-- >>> > >>> > #!/bin/bash >>> > # >>> > # File: asterisk-watchdog.sh >>> > # Date: 2015.05.26 >>> > # Build:v1.0 >>> > # Brief:Secuencia para monitorizar procesos. >>> > # >>> > # ${PATH}: Variable de entorno con las rutas a los ejecutables. >>> > PATH=/bin:/sbin:/usr/bin:/usr/sbin >>> > >>> > # ${DAEMON}: Demonio a monitorizar. >>> > DAEMON="asterisk" >>> > >>> > # ${MSG}: Cuerpo del mensaje a enviar por mail. >>> > MSG="$(date '+%F %T'): ${DAEMON} se ha caido!" >>> > >>> > pidof ${DAEMON} > /dev/null 2>&1 >>> > >>> > [ $? -ne 0 ] && { echo ${MSG}; service ${DAEMON} start; } >>> > >>> > exit 0 >>> >>> Both Debian 8 and Centos 7 have systemd.

Re: [asterisk-users] Which tool to automatically restart Asterisk ?
Hello; Over time, we’ve built a huge enterprise level monitoring system for our internal and customer PBX’s. Using Nagios as the core, along with Grafana, Graphite, Carbon, Whisper, etc. so we can also create custom dynamic dashboards, we typically monitor over 1,000 different metrics for each PBX. For something like monitoring a system process like Asterisk, besides just checking to see if the process is running or not, we also check about a dozen or so related metrics like memory and cpu usage. If anything gets out of whack, the system runs the event handler to restart Asterisk. All the plugins are written in Perl, so they’re very easy to modify. What I can do if there is an interest is take the Asterisk plugin, strip out everything that wouldn’t apply to someone not using our system, and make it available to the general public. It's up to you guys. What do you think? Would people find that useful? Regards; John V.
