Adding custom metric #841
Description
Hi! I would like to add LTE modem signal strength to the available data (metrics) provided on the page serverinfo.
I have a Python function which gets this data from LTE modem which can be run as modem_signal.py http://192.168.0.1 and provides the output like Orange PL LTE ▂▃▄.
#!/usr/bin/env python3
"""
Display 4G/5G modem signal strength using vertical bars and show operator + access mode.
Example usage:
python3 modem_signal.py http://admin:[email protected]/

What is the best way to embed it to the serverinfo page?
