The Event Reporting module is a powerful tool used to collect and classify events, associating them to BMC TrueSight Capacity Optimization metrics.
IT events may be roughly classified in two categories: macroscopic and microscopic events.
A macroscopic event is the (potential) cause of a problem, the log of a problem, or the log of an activity.
For example, a service unavailability or a database restart are macroscopic events.
Macroscopic events are generally reported as low volumes of time-significant events. They are often reported as the result of human analysis or logging (journal).
A microscopic event is the symptom of a problem or accident, and is traced as an effect.
For example, tickets in a customer care platform are microscopic events.
Microscopic events are generally reported as high volumes of brief events. Often, the cause of these events is uncertain, and the single event only traces the microscopic effect (e.g. a specific customer could not connect to the web site).
The obvious differences, both in scope and frequency, of the above mentioned types of events lead to a distinction in the procedures used to import them into BMC TrueSight Capacity Optimization:
It is possible to make a distinction between two kinds of macroscopic events, based on the predictability of the event itself
The classification of events
The following topics explain how to work with macroscopic events:
