= INSTOOLS, Instrumentation Tools = Instrumentation Tools, or INSTOOLS, is a network instrumentation and measurement framework designed to make it easy to track and understand network behavior. INSTOOLS consists of three basic components: * Instrumentation: data capture tools are deployed at points in the network to capture data. [wiki:Instrumentize instrumentize] * Measurement: data is captured while the system is running. * Presentation: the processed data is presented to the user. [wiki:SlicePortal INSTOOLS Portal] and [wiki:INSTOOLSInterface INSTOOLS Live View] The INSTOOLS framework is designed to make these components easy for the user to specify, configure and deploy. The INSTOOLS user does not need to be an expert in system administration or network management, The goal is not to reinvent the wheel, but, rather develop ways to automatically deploy and leverage existing tools. Network state information is typically more important than packet trace information, therefore many of the tools used measure data such as routing tables, packet counters (e.g., interface counters), cache entries (e.g., ARP, DNS, and NAT tables), processor load averages, memory statistics, host configurations, firewall rules, etc. A measurement plane, separate from the data plane, is created to minimize interference caused by the various measurement tools. === Presentations === [http://www.netlab.uky.edu/p/instools/ Protogeni Tutorial: USING INSTOOLS] GEC9 [http://groups.geni.net/geni/attachment/wiki/Gec7InstMeasWGAgenda/griffioen%20%20instools_imwg_gec7.pdf GEC7 Conference slides] March, 2010 [http://groups.geni.net/geni/attachment/wiki/GEC6InstMeasWGAgenda/UK_IMWG_11-2009.pdf GEC6 Conference slides] November, 2009 [http://groups.geni.net/geni/attachment/wiki/presentations/GEC3_Kentucky.pdf Instrumentation Tools for a GENI Prototype], GEC3 Conference, 2008 (outlines the project goals and relationships with other projects).
