ChkWAN automated monitoring.

[miazza]

I have installed the chkWAN script following the instructions in https://github.com/MartineauUK/Chk-WAN.

Now I'm trying to have it installed in cron for automated monitoring.

I have done this:

cat > /jffs/scripts/wan-event << EOF;chmod +x /jffs/scripts/wan-event
#!/bin/sh

if [ "\$2" == "connected" ];then
   # sleep 5
   # No need for recommended 'sleep n' as ChkWAN.sh has default 10 secs delay
   # Check WAN connectivity every 5 minutes
   sh /jffs/scripts/ChkWAN.sh cron="\*/5 \* \* \* \*" &
fi
EOF

But this is just updating the wan-event script.

In order to add the cron job

*/5 * * * * /jffs/scripts/ChkWAN.sh #WAN_Check#

I needed to add it manually with

crontab -e

Is this the right way ?

Hi, I have had a number of instances this year where my XT8 is up and running as normal, i.e it is serving the WebUI, Wifi and you can log into SSH, the GUI shows internet connected, but there is no connectivity on the external WAN connection. The separate modem is also connected and synced...

I actually prefer updating the event scripts to run the ChkWAN script directly. That's also described in the GitHub readme.

By doing this, whenever the internet connection comes up, the ChkWAN script is kicked off and it starts monitoring the internet connection. When the router first comes up and then the internet comes up, the ChkWAN cycle starts. When ChkWAN sees that the internet connection is down, it restarts the WAN connection and ends. By doing so, when the internet connection starts again, ChkWAN starts up again and the cycle continues.

I find this works well for me as whenever my internet connection was having issues, I was just stopping and restarting the WAN connection. The CRON option is fine but doing it without CRON avoids the possibility of multiple ChkWAN scripts running at the same time. Not sure if that's actually possible.

Working well for me. Thanks @Martineau

Well, my question was indeed a bit different.
I like the cron version and I edited cron via the crontab -e adding the code */5 * * * * /jffs/scripts/ChkWAN.sh #WAN_Check# at the end.
This will launch the ChkWAN.sh by default every 5 minutes.

The event script was not working for me , I found my router with the wan red led and no wan working... needed to powercycle the rooter.
