Jess,
We are looking to provide a report to management on availability of Windchill system over a week/month. If the Windchill home page URl was available/accessible then we could consider the system as up. That would translate to atleast one of the slave node and master being up.
The server status page shows the current uptime. So potentially, if we can access historic data, we could calculate the uptime(did not know we could access historic data). PSM on the other hand does "ping" the system in different ways and thought someone might made some measures in PSM for this.
Thanks
