Dear All,
Java-monitor has been updated to also show your CPU utilization.
Like most popular CPU utilization tools, we show the CPU load as a percentage, where 100% is one fully loaded processor. Thus, if your system has 4 processors, you can expect to see up to 400% CPU load.
The CPU graph is best used in conjunction with the UNIX load graph, which is shown for all UNIX systems that support this graph (if your Linux version does not show UNIX load, upgrade your OS and your JVM). Essentially, if the graphs are closely correlated, this shows you that your JVM is the main pig on your processors. If, on the other hand, the UNIX load is high at times that the CPU load from the JVM is low, there are other processes running on the server, potentially slowing down your JVM.
We also round off some of the values here and there, for easier reading.
