DUTIES OF SYSTEM ADMINISTRATOR(Monitor and Tuning Performance)

Monitor and Tuning Performance

1.     System tuning is an ongoing process aided by a variety of diagnostic and monitoring tools.

2.     Some performance decisions are made at installation time, while others are added or tweaked later.

3.     A good example is the use of the hdparm utility, to squeeze the best performance from your equipment, monitor your system carefully and use Linux built-in configuration wisely.

4.     Proper monitoring allows you to detect a misbehaving application that might be consuming more resources than it should or failing to exit completely on close.

5.     Possibly most important, careful system monitoring and diagnostic practices give you an early heads-up when a system component is showing early signs of failure, so that any potential downtime can be minimized.

6.     Combined with the resources for determining which components are best supported by System, performance monitoring can result in replacement components which are far more robust and efficient in some cases.

7.     Careful system monitoring plus wise use of the built-in configurability of Linux allows you to squeeze the best possible performance from your existing equipment.

This Includes customizing video drivers to applying special kernel patches to simply turning off unneeded services to free memory and processor cycles.
