Configuration Guide SEM Configuration
SEM supports a named counter used inside the SEM system. The SEM counter event
detector will detect the variance in SEM named counter, and the value of SEM named
counter will be controlled by SEM counter action during policy execution. SEM named
counter can be used by the policy to trigger such actions as summation, numerical value
statistics and etc. For details, please refer to "SEM detection of counter" in "Typical SEM
configuration example".
Working principle
Fig 1 SEM structural diagram
SEM provides different kinds of event detectors, which are embedded in different
services to monitor service operation in a real-time manner. These detectors will compare
the conditions generated through user configuration with the service operation events.
Once matched, the event detector will notify the intelligent management server of event
occurrence.
The intelligent management server will determine whether the event can trigger the policy
according to event configurations in the policy. Once the event meets the policy trigger
conditions, the intelligent management server will execute the policies in policy manager.
The policies in policy manager will execute the preconfigured actions in turn according to
user configurations.
