The Types of Monitoring
Stateful monitoring is specially developed to keep track of the known attributes that have defined thresholds (for example, memory or disk space usage, workflow of the process etc.). In general, this type of monitoring tools checks the condition of the individual components of the platform and notifies IT stuff if any component reaches the threshold. This type of monitoring is appropriate in case if you need up-to-minute view of the condition. The data collected by stateful monitoring is the best used for the analytics of the performance.
With help of this data an operator can check the performance of the platform through different usage patterns. For example, by tracking the number of requests to the server it is possible to create the pattern of requests and monitor only deviations.
