Baseline Monitoring for troubleshooting in Linux!

The Baseline Monitoring is useful in :-

  • troubleshooting
  • essential for healthy systems
  • help plan for further growth
  • can aide with security

A good baseline monitoring of systems is very helpful in troubleshooting. A good baseline of system activity and use can be used to compare when a system appears to be behaving erretically, or more activity to report when a system is operating outside of specified parametres.

It can aslo be used to tighten the security. As we can build up trends for our systems and networks over time, using these we can more easily spot events outside of the norm which could be attempts to gain access to our systems or a rogue system already under the control of external influences.

Deciding what to monitor is very dependant on the work that a system does. For database servers or file servers then disk space, service availability and load might be important. For a desktop system we might justcheck to see that its up and running.

Data gained from longer monitoring can be used outside of the purely technical. We can use it to measure the growth of system load over time, and to predict when a new server of file store might be required. We can use to how improvements made are impacting service availability and therefore helping work flow and numerous others.

thanks & regards
