In addition, the collection and cross correlation of various network metrics (that perfSONAR provides) in order to identify a performance 'culprit' can provide an extensive method of wading through the vast amounts of data. It will also provide a means by which problem tickets can provide more useful information than simply that something is wrong 6We first experimented with Multi-route Event Detection using PCS 6, however the results were disappointing. We then looked at mining the events detected to look for correlations and reduce false positives and negatives and provide improved diagnostics 7. Though it had some successes, the work should be classified as only the preliminay investigation of the overall problem.
