Java Analysis
Java Thread Analysis - as of ZVPS 4.3
As we at Velocity Software dig deaper into system analysis, the application subsystems become the next step in understanding how the server is performing and why. In zVPS 4.2, java process data was provided. In zVPS 4.3, we now provide thread analysis with a suprising capture ratio - not only do we see the block I/O and wait time for those block I/O, there are also thread waits - and CPU consumed by thread is provided. The following report is available as of zVPS 4.3.
The "CPU ms" per thread in the last column is milliseconds of CPU used by the thread during the interval - in this case, the summary is for 15 minutes, but real time, this information would be available minute by minute.
