Super Aggregation

The Aggregate Table contains per default an entry for all self and process monitors with the same object class, instance, and attribute, but different severities (different thresholds). The table aggregates on a severity level (standard aggregates).

Additionally, the table enables super aggregations on a class level, attribute level or instance level. Corresponding table entries use an asterisk (*) as a placeholder.

Attribute level

There is one entry for all monitors with the same object class and instance (aggObjAttribute set to *)

Instance level

There is one entry for all monitors with the same object class and attribute (aggObjInstance set to *)

Class level

There is one entry for all monitors with the same object instance and attribute (aggObjClass set to *)

A combination of the above three levels can be configured in the sysedge.cf file, causing aggregations up to an overall agent state.

The index of super aggregates starts at 100001.

Important! Setting the row status attribute of the *, *, * entry to destroy (6), effectively deletes all monitors with a severity greater none (1).

Aggregation levels can be configured in sysedge.cf file according to thr following format:

aggregate_level level
level

Specifies a bit field allowing to specify the following aggregation levels:

001: Aggregate all monitors with same class and instance in an entry with attribute set to *

002: Aggregate all monitors with same class and attribute in an entry with instance set to *

004: Aggregate all monitors with same instance and attribute in an entry with class set to *

010: Aggregate all monitors with same class in an entry with instance and attribute set to *

020: Aggregate all monitors with same instance in an entry with class and attribute set to *

040: Aggregate all monitors with same attribute in an entry with class and instance set to *

100: Aggregate all monitors in an entry with class, instance and attribute set to *

The entries of the aggregate table (only some selected attributes) is stored in the sysedge.mon file. The main purpose is to store the index of an entry between restarts, because typically a manager uses the index to poll the object and relies that the index does not change frequently.
