Performance Monitoring

Monitoring or Monitoring?

When people come to talk about monitoring, each one has his own understanding of what is Monitoring.

Not so often people know that there are different kinds of monitoring. We will try to give some definitions.

First, you have 2 main kinds of IT systems monitoring: performance monitoring and availability monitoring.

Performance monitoring tries to give an image of the ongoing performances of the system, while availability monitoring only tests if the system is accessible, whatever the performances are.

But within these 2 large categories, there are many kinds of monitoring, each giving more or less information on the monitored system.

The answer to availability monitoring questions is always yes or not while the answer to performance monitoring questions is a time measure or a percentage. Obvious?

The follow-up of data-processing applications Quality of Service requires powerful tools and accurate competences. The produced and published data must make it possible to appreciate with accuracy the infrastructure Quality of Service total level and the real defects impact on users.

Performance Managers has developed a whole set of tools and competences to quickly implement an application monitoring platform, making it possible to measure data-processing applications Quality of Service, to validate measurements adequacy to the Contract of Service, to provide clear data for the defects resolution, and to even start preventive actions before real users do not feel the impacts of them.
