System Management & Monitoring System
System Management, in particular for server and mission critical system (ie Server Management) is essential to ensure that the underlying infrastructure of business-critical applications is in fine shape. The goal of any system administrator is to ensure that the various systems and servers are running smoothly, know how loaded (or overloaded) a system is, and how effectively they are utilized (or overused).
For modern system monitoring go beyond availability and performance monitoring. Typically also involved "services" monitoring as well as "application performance monitoring (APM)" under Application Management.
Server Monitoring involves monitoring of server load, disk utilization, processes, memory utilization, Disk I/O stats and server CPU utilization among other parameters.
Applications Management, along with Server Management, enables an IT administrator to identify whether a problem reported is caused by the underlying operating system, the application or a service. This will help make effective changes in the resources quickly and reduce application bottlenecks.
