It could be useful to monitor network data usage, especially on a 750-8217, to avoid a bad surprise on your mobile operator’s bill.
With the vnstat package, you can monitor the data consumed on each interface.
It provides a simple but efficient webpage to get access to information.
You can also export data as JSON output, or even get information using command line.
A script could be easilly set up to get the data in the IEC61131 program using the WagoAppConfigTool library.
A dockerised version of this application can be found here :
https://github.com/vergoh/vnstat-docker
You can easily set it up using the following command :
docker run -d \
--restart=unless-stopped \
--network=host \
-e HTTP_PORT=8685 \
-v /etc/localtime:/etc/localtime:ro \
-v /etc/timezone:/etc/timezone:ro \
--name vnstat \
vergoh/vnstat
Enjoy !
