Monitor and then Restart Domoticz Automatically if it stops

[thebeetleuk]

Hi all,

I've tried searching the forum but I cant quite see this anywhere.

Every so often (i.e. again today when my wife tried to use the heating!!) Domoticz doesn't display anything through the browser and I have just restarted my pi. Finally today I'g going to attempt to resolve the issue so I was thinking I could monitor domoticz to make sure I am still getting a reply and if not then restart using

sudo service domoticz.sh stop
sudo service domoticz.sh start

Any ideas how I can do this?

Thanks!!

Hey,

Give this a try:

I can underscribe the Monit-solution to keep Domoticz up and running.

But check to be sure that it is domoticz which is failing.

Happened to me just a few times with the stable version. Enable logging to file, seems to be disabled by default! And write to a remote location (using nfs-export on NAS myself). And see that it ia definedly domoticz stopping.

When it happened to me most of the time mobile/wifi device disconnected earlier. Refresh returned with no devices.

Now using Monit to keep Domoticz up and running. Webinterface comes handy in the case that Domoticz isnt available so restart service/restart pi. And mobile android-devices configured with a home-screen shortcut that makes the Domoticz dashboard a WepApp.
Running two weeks now without probs for now.

Well I have issues with wifi and raspberry and some "unknown" crashed of domoticz itself.

First solved from this link -> http://iqjar.com/jar/raspberry-pi-reboo ... -networks/
I have also a second domoticz slave server and they inter-control each other!

Second solved by this post -> http://www.domoticz.com/forum/viewtopic ... 016#p46752

Monit is the way to go.

I am using the latest beta of Domoticz and it is very stable - at least in my environment. I do not upgrade to the latest beta as soon as it becomes available, but wait for a couple of days, checking this forum for problem reports. In my experience it is relatively safe to upgrade after a week or so when it is quiet in the forum.

I use a simple bash-script wich is run every minute by crontab:

Code: Select all

#!/bin/bash

if [[ ! "$(sudo service domoticz.sh status)" =~ "domoticz is running" ]]
then
  if [ ! -f /tmp/stopdomo ]; then
    echo "`date`: Domoticz not running - restarting..."
    sudo service domoticz.sh start
    echo "`date`: Domoticz restarted!"
  fi
else
  if [ -f /tmp/stopdomo ]; then
    echo "`date`: Domoticz is running - stopping..."
    sudo service domoticz.sh stop
    echo "`date`: Domoticz stopped!"
  fi
fi

If i don't want to auto-start Domoticz, i place a dummy-file named 'stopdomo' in /tmp

Wow thanks everyone. I'll try some of these tonight!!

It's not very normal that domoticz stops, but it can happens . See if you did expand your sd card and use the full size. Mostly (for me) the sd card was causing the trouble. Setting up a fresh domoticz may also help. Use monit, there is nu better solution:-) if you need help to setup, please let us know. Good luck !

How is this script acting when you update Domoticz?
Is there no problem ?

Still trying to work out what's stopping. its not the SD card as I expanded as soon as I setup over a year ago.

Strangely one of my friends who also has Domiticz has the same periodic issues as me. The web gui appears to stop working.

How do I enable logging on domotics to check for errors?

No problem here but not sure how this would impact anything

[thebeetleuk]

P.s. I still need to investigate more. I have been side tracked with a lua script that sends me a notification me a message each time a spend a £1 on electricity. all done now so back to this

When 2rpi's are checking each other, both will reboot when 1 fails: the one failing won't leave the trace behind on the second rpi, which will think that it has a problem itself

Or do I miss something?

[stlaha2007]

@jake, don't think your missing something.
If one fails it can't leave an error on second.

@thebeetleuk
Anyway: enable logging to /var/log/ etcetera. Basic raspian does some itself!
Domoticz enable in /etc/init.d/domoticz.sh
Also look into daemon en message logfiles.

Try do get some lines from those with the errors/crashes including some before and after.
Makes it easier for us to understand where its failing.

I have something to restart. A slight modification to what is on the wiki but it seems to work. I'll need to add a line to notify me when it restarts and then I can investigate the logs.
