Wouldn't it be nice if network devices could collect & process their own netflow data and email you the results? Well, now they can!
This tcl script tracks the local netflow cache and generates "Top Talker" reports. Reports are run from CLI or configured to run automatically from Kron with the results sent via email. The script works by tracking and periodically storing netflow cache data in local log files. The reporting engine analyzes the log files to provide Top Talker reports from any of the previous five days. This script runs locally and does not open or make network connections with the exception of the built-in IOS smtp_send_email function. Performs best on ISR G2 or similar with latest IOS.
