Hello Extension team,
I am using Generic Cisco device extension, I noticed that the the uptime it's showing for my router is wrong. Dynatrace need data being reported to the metric com.dynatrace.extension.snmp-generic-device.sys.uptime. This metric should report the time since the network management portion of the system was last re-initialized. The OID for this metric is 220.127.116.11.18.104.22.168.0.
The problem is with 22.214.171.124.126.96.36.199.0, it is a 32 bit integer and shows in centiseconds, as a result it cannot go further than 497 days, it resets after that. uptime of the router which I am monitoring with Dynatrace is 1165 days but Dynatrace is showing 171 if we do the math 1165-(497x2)= 171.
The workaround that other monitoring tools like solarwinds are using is to use 188.8.131.52.184.108.40.206.1.3 (snmpEngineTime) instead.
I have looked in Cisco backlog, it doesnt look like there is any apetite to fix 220.127.116.11.18.104.22.168.0, it would be great if you could change the extension to use 22.214.171.124.126.96.36.199.1.3 istead.
