Fluentd

While log search and analysis tool Splunk is offered in a free version, its enterprise functionality doesn't come cheaply. Organizations that can't come up with the cash may be able to build out a similar approximation of features using Fluentd as a foundational open source log collector and chaining that together with ElasticSearch and Kibana, a pair of open source tools that offer search engine and Web UI functionality and which together with Fluentd can create a comprehensive way to collect data, analyze it and visualize it for free.

re: 10 Free Network Analysis Tools
www.networktimeout.com is a free online packet analysis service that uses the protocol parser included in ExtraHop's real-time product. This service analyzes packet dumps and teases out critical metrics for HTTP, CIFS, Citrix ICA, all major databases, TCP, and more. It's like having network engineers pouring over your packet dump with Wireshark for 10 hours ... but in a minute.
