Quick Script to check the uptime of ASR920's

Wed Feb 20 19:20:18 UTC 2019

I realize you’re aiming for the NETCONF paradigm, but for anyone interested, a more consistent, device- and release-independent method is to just query the SNMP uptime variable:

$ snmpget -v 1 -c demopublic 10.1.2.1 system.sysUpTime.0

system.sysUpTime.0 = Timeticks: (586731977) 67 days, 21:48:39.77

Erik,

Just in case you want to go into/learn the data model-driven management, here is a NETCONF/YANG script.

Thanks to Djordje for developing this script.

All,

I just created a quick script to check the uptime of a ASR920 via SNMP if you have a fairly long list of devices. It's a simple bash script and snmpwalk version 2c. Figured I would share it with you. Happy Friday

Grab the code from GitHub: https://github.com/esundberg/CiscoRouterUptime
It's a quick and dirty script and my first repo on github. Let me know if there any issues with it.

Output Format in CSV
DeviceName, IP, Uptime in Days, OK/Warning

I set my warning to 800 Days, you can change this in the code

ASR920list.txt

ASR920-1.SEA1, 192.168.28.1, SuperSecretSNMPKey
ASR920-2.SEA1, 192.168.28.2, SuperSecretSNMPKey
~~~~snip you get the idea~~~~
