Chapter 3. Monitoring Processes, Services, and Events

As an administrator, it's your job to keep an eye on the network systems. The status of system resources and usage can change dramatically over time. Services might stop running. File systems might run out of space. Applications might throw exceptions, which in turn can cause system problems. Unauthorized users might try to break into the system. The techniques discussed in this chapter will help you find and resolve these and other system problems.
