Quick Script to check the uptime of ASR920's

Sat Jan 26 00:39:26 UTC 2019

Erik,

That’s a nice little script. Thanks!

So you want a warning if a router hasn’t been rebooted in a long time?  Just out of curiosity, why? I’m kind of glad that my routers don’t reboot, pretty much ever. Usually I want to know if the uptime suddenly became less than the most recent uptime, indicting a possibly unplanned reboot.
