INSTOOLS, Instrumentation Tools - Deprecated deployment process

INSTOOLS can now be added to your slice using FLACK and a single button press. See INSTOOLS Summary for details. For documentation purposes and project history, the following describes the former script method.

Instrumentation Tools (INSTOOLS) is a network instrumentation and measurement framework designed to make it easy to deploy network measurement infrastructure into a slice. Once deployed, INSTOOLs allows the user to "see" the network behavior using a standard web browser. From a user's viewpoint, there are basically two steps required to use INSTOOLs:

  • Instrument the Slice: The user runs a script that deploys the necessary network monitoring software into a slice which then begins collecting network traffic measurements for that slice -- see instrumentize
  • Visualize/Graph the Collected Measurements: After instrumenting the slice, the user is given a web page to visit in order to "see" a live view of the network traffic flowing through the slice. Users can either use the Portal View INSTOOLS Portal that shows the slice on a map and allows users to click on any link or node in the slice to see its performance. A second interface INSTOOLS Live View provides a very detailed live view of the links and nodes supported by a particular aggregate.

The INSTOOLS framework is designed to make configuration, deployment, and visualization of measurement data easy. 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.

Each slice receives its own Measurement Controllers (MCs). These machines are responsible for capturing the data. Currently the slice has at least one MC per aggregate. This ensures scalability and efficiency since each set of instrumentation tools is tailored to capture, record, and display only the desired information associated with that slice.

The MC's create a measurement plane which is separate from the data plane. This minimizes interference with the slice caused by the various measurement tools.

To get started using INSTOOLS see instrumentize.
