Question

ITCO251 What is an important issue in fault monitoring?

Answer 1

Any computer system will fail, given enough time. Hardware problems, such as a power failure or component defect, can bring it down. The software might have a bug that rare circumstances trigger, or an external attack exploiting a flaw might stop it from running properly. A required external service might go down. Operator error might mess everything up.

The two main fault monitoring are active and passive. we can use both types of monitoring in a system.

active monitoring ping a service andwait for the response.if the response not get in particular interval of time then indicatea problem.

effeffective use of active monitoring requires striking a balance between performance and detection.

Passive monitoring covers several methods. If the software detects a severe error, it can signal the monitoring system. If both the application and the monitor follow the syslog standard, this is fairly easy to implement. The monitoring system can also detect timeout errors and take action if there are too many.
