Home Monitor is an application built on Splunk that allows any user to view the network traffic moving through their home router. This application takes the syslog feed from your router and breaks it out into ports, IP Addresses and locations based on IP addresses.
These are all free downloads from splunkbase. Splunk Version 6.x and above is recommended since this app leverages the sparklines command report acceleration. Make sure to upgrade to gain the full benefit of the new release.
This app has been made to be compliant with CIM 4.0 and now works with Asus, pfSense 2.2.1+ [tested], Netgear, Skyhub, OpenWRT [not tested], Mikro-Tik [tested].
The latest version has a simple workflow that helps users leverage the dynamic dashboards to see the flow of traffic through their home network. It's a work in progress, so please let me know what you think.
