I have read about people trying to use Modbus to collect information, and it doesn’t seem that anyone has posted a success story.
I am about to get a Fronius inverter which supports Modbus TCP.
I would ideally like to collect the information from the inverter and the graph it on my LibreNMS monitoring server. That way all my monitoring is in a one stop shop.
I am aware of the Check_modbus_tcp Nagios plugin, but I’m not sure how I graph the information, if I managed to collect it.
I would greatly appreciate some additional pointers as to where I can look to make this happen.
