Need to monitor VPN (Barracuda Firewall) using Grafana dashboard

Need to Barracuda Firewall VPN like how many active users are connected. Barracuda VPN are monitored through Barracuda firewall exe setup and the version is 9.0.4. Kindly suggest various methods and steps to make it work

I would use SNMP. It seems, it’s the preferred way.

Needed oids are:

metric description OID
status status vpn tunnel .1.3.6.1.4.1.10704.1.11
count tunnel count active vpn connections .1.3.6.1.4.1.10704.1.6.1.2

To collect metrics you could use grafana alloy. Easy to set up and forward the collected metrics to something like mimir for storage.
