We are noticing some wrong up time values for a lot of devices – see the screenshots below. We tried to poll, re-discover and re-add the node without success.
Noted that it is due to 32 bit counters of IOS system up time. However, it seems we can poll snmpEngineId (.1.3.6.1.6.3.10.2.1.3) which returns the uptime in seconds and should not roll over for 135 years.
Will SolarWinds calculate the time and show the last boot time in Web Console?
