Step 3 – writing script

This is where we write a script to ensure we capture the specific status of every interface on a given set of routers and write it back to a file. This would also be ingested by Splunk.

In our case, we would fetch the stats from all of the routers (192.168.20.1-192.168.20.4) every five minutes and update the file in C:\splunklogs. In other words, Splunk would have the refreshed the data that we can use for validation every five minutes. Another benefit of this approach is for historic data collection. Using this approach, we can always determine the Root Cause Analysis (RCA) or even identify any flaps or an interface utilization over a period of time, we can leverage Splunk for data analysis.

Let's split the code into ...
