I want to monitor packet loss on my ASA 5505 VPN endpoints using SNMP. This is so I can graph the rates in Cacti and/or get alerts in Nagios.
However, I am not sure what SNMP values I should use to measure packet loss.
In the ASA I can run
sh interface Internet stats to show traffic statistics for the interface connected to the Internet. This shows 1 minute and 5 minute drop rates.
- Are these measures an indicator of packet loss?
- Are there SNMP values I can access that correspond to those values?
- Should I be looking at different values?
- Is the ASA even able to measure packet loss?
