Device is cisco router with IPSec VPN tunnels. I used custom SNMP with imported library and PRTG draw graph, and all is working ok untill tunnels is stopped and reestablished. Then tunnel change index and I have invalid sensor.
Manually OID is 126.96.36.199.188.8.131.52.184.108.40.206.1.7.xxxx where "xxxx" is some index number which change every time tunnel is reestablished.
How to resolve this problem?
