jboss performance monitoring

A disk is usually the slowest subsystem of a computer, and it is also the most prone to performance bottlenecks, because the disk is the farthest from the CPU and the CPU access to the disk involves mechanical operations, such as rotating shafts and track searching. The speed difference between hard disk access and memory access is calculated by an order of magnitude, just like A disk is usually the slowest subsystem of a computer, and it is also the

Looked at such a tutorial, read a manual, according to the requirements to change a set, system settings, kernel parameters that the idea of a system optimization is silly very naïve: the system optimization is a complex, cumbersome, long-term work, optimization needs to be monitored, collected, tested, evaluated, optimized after testing, collection, evaluation, monitoring, And is a long-term and continuous process, not to say now optimization, testin

1. Overview Monitoring is an indispensable part in checking system problems or optimizing system performance. The operating system monitoring tool monitors the usage of operating system resources and indirectly reflects the running status of each server program. The analysis based on the running results can help us quickly locate the scope of system problems or
