RE: Lost PERFSTAT bridge scripts

Jared I already did but I must have been half asleep(or more) because he
does say



"its impossible to report across a shutdown, but it is possible to reduce
the lost periods of time (10:00 to 10:15 and 10:20 to 11:00 in our example)
by automatically performing snapshots before shutdown and after startup. Its
easily done with BEFORE-SHUTDOWN and AFTER-STARTUP triggers."



        I do use a script from Tim Gorman that works very well (below)

Nice idea.  Please share when you find it again.



DB bounces mess up my pretty response time charts.  :)
