Dashboard or report on Network Device Config being pulled.

I am still learning how to create dashboards for broad information summaries.

We have our Network Devices also pulling Configuration files but wanted to create a summary dashboard that could contain information like.

Location    Network Devices Count --  Config File Count 

Blue Ridge facility - 15               10 
New Orleans Facility - 20  -  20

 

This would show that the Blue Ridge office has 15 network devices - but only 10 of them have a config file

while the New Orleans office has 20 network devices and all 20 have a config file.

Config files can be in different folders based on the device type - eos-config; ios-config; config
But I would like to sum them all together.

This would be used to assist with ensuring that the facility is completely monitored

Suggestions?
