Hi there,
I can help you to setup FreeSwitch monitoring using mod_event_socket of FreeSwitch and export metrics into Prometheus to plot charts in Grafana dashboards. I'll need remote access to your FS and some compute resources to run Prometheus with Grafana (it can be your server or external server). I'll also need some hints on what exactly you need to monitor at first stage (can be extended later).
HI I am a system administrator. I have great experience in monitoring FreeSwtich pbx and asterisk. I have already local setup so i can show you a demo
Please ping me so we can discuss further
Basically, if you want a monitoring tool that helps you to troubleshoot your organizational environment-related I.T solutions. LibreNMS is the best solution and it is open source and 400 network monitoring tools are in one solution. I am glad to configure this server for you.
