Engagement Activities - Chas give a review of each of the activities that the group is engaged in. The following are a list of the most active,

• Chas attended the LionShare project planning meeting in San Jose. He was encouraged by the fact that the group was very receptive to input regarding distributed diagnostics. It was also early enough in the implementation process to make a positive impact. Both Alex Valentine (PSU) and Marek Hatala (SFU) would be participating in the requirements gathering process. Scott Thorne (MIT) introduced Chas to the the details of OKI, and discussed ways they the E2ED diagnostic architecture may consider using interface abstraction layers to reduce risk.
• The MACE-DIR group was also very receptive to the E2ED group activities. Chas spoke at the bi-monthly meeting of MACR-DIR through an invitation from Keith Hazeltion. Two members of MACE-DIR, Brendan Bellina (ND) and Michael Grady (UIUC) would be participating in the requirements gathering process. Keith offered an introduction to Paul Bradford from the Wisconsin Advanced Internet Laboratory, which he thought would make a great participant and possible test bed for the tools that E2ED would be developing. Chas agreed, and would contact Keith for an introduction when the groups architecture plans have matured.
• Von Welch (NCSA) had produced a very comprehensive question and scenario documents. The group thought that he canvassed many of the problems that administrators and operators would encounter.
• Matt Zekauskas invited Chas to attend at the Performance Measurement Architecture Workshop in December at SDSC to give a short talk on the groups activities and a view into the preliminary architecture. Both Matt and Russ Hobby were interested in the architecture's independence of measurement data collection, the data repository operators, and the tool API that is solidifying within the E2ED group. Also, the concept of the architecture's top-down approach may foster an interesting discussion at the workshop.
• During mid-December Chas will be conducting interviews at CMU with members of the academic computing services group and targeting architects, administrators and operators of middleware applications.
• Ken Klingenstein has introduced Chas to Lynn McRae, the lead of the development of Stanford's authority system. Chas will be setting up a meeting to discuss possible collaboration.
• Michael Gettes and expressed interest in Duke participating in both the development and initial testing of diagnostic tools when the group is ready for engagement.
• Matt Mathis (PSC) has been providing feedback on the preliminary architecture, with respect to scale, configuration, a common event record, and network measurement issues.

Requirement Gathering Activities

The group reviewed the scenario writing process activity from the areas of MACR-DIR, GridS, Shibboleth, P2P, and IM. It was suggested that Matt Zekauskas and and Russ Hobby participate in the scenario writing process.

Requirements Matrix

The group reviewed the preliminary requirements matrix document that was produced from both interviews and the scenario processes thus far. The matrix will continue to be fleshed out until both processes were competed. It was also suggested that the privacy issues be flagged as separate category in the matrix.

Preliminary Architecture Discussion

The group did a cursory review of the preliminary architecture of the diagnostic backplane document. It was decided by the next meeting that each member would review the architecture and be prepared to make comments.
