    7676The [http://seer.isi.deterlab.net SEER experiment control tool] is a useful way to manipulate a TIED experiment to both carry out the experiment and to examine real time data from the experiment.  Other Emulab-style measurement gathering and event systems function as well, but SEER is a convenient, extensible system.

     78We focus on SEER, DETER's agent-based experiment management system.  Without modification SEER presents a diverse set of agents that can configure nodes, send traffic (both benign and malevolent), and collect data.  In addition, real-time data can be collected graphically.  The following short tour gives an idea how to use SEER and shows some of its potential.  More complete [http://seer.isi.deterlab.net documentation of SEER] (including video demonstrations) is available.

    7880Once an slice is created that includes the SEER code - the [http://seer.isi.deterlab.net/trac/wiki/HOWTO/Setup SEER HOWTO] explains the commands one must include in the experiment configuration language one must make to include the SEER base system - the SEER front end can be used.  One can start the front end using the [http://seer.isi.deterlab.net/gui/SEER-GUI-1.5b3.jnlp webstart link] on the SEER page.  Alternatively one can download the source from there and compile and run SEER locally, though we don't recommend it.

    98 One can get a real time summary of traffic between nodes by selecting the node on the topology and requesting a graph.  The graph appears under the "graphs" tab.
     100One can get a real time summary of traffic between nodes by selecting the node on the topology and requesting a graph.  The graph appears under the "graphs" tab.  In this case the graph shows infrequent routing traffic (which is largely extraneous for such a simple slice).  To see more, we initiate a ping below.

     109Once the ping has started, it shows up in the traffic graphs from the nodes.  This screenshot includes graphs for both `a` and `b` in the slice.  The previous routing traffic remains, but the additional green traffic is the ping that occurs once per second.

     111=== Getting more from SEER ===

     113SEER has a broad array of traffic generators and attack traffic available without modification.  In addition experimenters can add agents to SEER to perform arbitrary actions in the experiment.  The data retrieval and data reporting systems are similarly customizable.
