measuring availability for clusters

Chris Hubbell has started blogging about his work with the Configuration and Service Tracker (CST). CST is designed to track availability of single domains. We also have the ability to track and correlate availability for clusters. We have been tracking a number of clusters running Sun Cluster 2.2, 3.0, and 3.1. This allows us to measure how well our improvements to the product are reflected in the actual availability at customer sites. The good news is that the availability is improving. Every week we get a report of the extended outages and we have a team who investigates these to determine who we can prevent them in the future.
