Add custom graph from files content

Hello,

My server has three files (fileA, fileB, fileC), they contain number and increasing when having requests to local service.

How could i add a graph to show on librenms for each file and an aggregation graph for total requests for three of them?

Thank you.

looks to be possible via snmp extend https://www.reddit.com/r/LibreNMS/comments/ahdykh/taking_simple_numbers_and_creating_a_graph/
