Monitoring quality (roundtrip) with SNMP
tech001 last edited by
In addition to SNMP monitoring of inbound & outbound traffic (kbps) of my pfSense, is it possible to also do SNMP monitoring of pfsense's "Quality", I mean the roundtrip times? (As in the RRD graphs -> Quality.) I tried to look at the MIB listings, but didn't find anything really…
Some background: I'm running MRTG at home, and it's collecting data from a pfSense 1.2.2 firewall/router at a remote site. It took a while to get MRTG/SNMP/pfSense working though: I had to...
- Enable SNMP on pfSense
- Create a firewall rule for allowing UDP/port 161 on WAN
- Add a NAT rule: port 161 gets NATted from WAN PUBLIC IP to pfSense's LAN IP: 192.168.1.1
- Check the "Bind to LAN interface only" option in "Services:SNMP" page
Without carrying out the steps 3 & 4, I was only able to see MRTG results by running MRTG on a machine in the LAN.
