Fine Tuning the eG Enterprise
Proactive alarm generation and their automatic suppression during maintenance periods are key capabilities of the eG Enterprise system to achieve the best performance monitoring.
Figure 11 briefly describes when and how alarms are triggered by eG Enterprise.
Figure 11 : How does eG generate alarms?
As is evident from Figure 11, the eG agents periodically download pre-configured/auto-computed standards of performance (per measure) from the eG manager. These performance standards are called ‘thresholds’. The eG agents then compare actual performance results with the standards. Deviations, if any, are noted and reported to the eG manager. The eG manager then, using a patented, virtualization-aware correlation algorithm, automatically correlates the performance results, intelligently triages the deviation reports, and accordingly assigns a severity/priority to each deviation. Based on the ‘alarm policy’ assigned to each measure, the eG manager then determines whether/not the deviation is severe enough for an alarm to be generated. If so, the manager triggers an alarm.
Alarms so generated can also be automatically suppressed when components are shut down for maintenance.
In this chapter, we will be discussing the concepts and procedures related to alarm generation and suppression in eG Enterprise. Broadly, this chapter will discuss:
- Alarm policy settings
- Threshold configuration
- Maintenance policy definitions
- Global Thresholds
- Viewing Thresholds
