Aggregation Rules
Aggregation Rules
The EDL Attribute property MetricRule is used to define the aggregation property of a
File or Process attribute. You can use these values:
The EDL definition for the Process Busy attribute is:
AT Busy Grid YES Graph YES GraphMax 0
Format "F6.2"
Help "Process Busy"
MetricRule SUM
StatePair YES
StateRule UseStateGraphState
TypeData REAL64;
The statement MetricRule SUM defines the aggregation rule, to sum all members of
the group. This statement can be changed to use AVG, MIN, MAX or CNT instead of
the summary, or the statement can be removed to cause the value associated with the
worst state to be propagated to the aggregate record.
Attribute Propagation
If no aggregation rule is defined for an attribute, the value associated with the attribute
with the worst state is also propagated. For example, if you remove the SUM rule from
the Process Busy attribute in the previous example, the Busy value for process
Sales\$A13 is propagated to the aggregate record instead of the sum of all processes.
By default, all File attribute values are propagated to the aggregate record. By default,
Process attribute values vary based on the MetricRule property.
Status and OpState
The Status attribute is handled differently than other attributes in an aggregate record.
The Status text field is used to show the number of members of the group and the
number that are issuing alerts. For example, if there are five files in the group and
there are no alerts, the Status text reads "5 Files." If there are five processes in the
group with one issuing alerts, the text reads "5(1) Processes."
SUM Sum the value across all members of the aggregate grouping
AVG Average the value across all members of the aggregate grouping
MIN Use the minimum value found in the aggregate grouping
MAX Use the maximum value found in the aggregate grouping
CNT Use a count of the number of values found in the aggregate group
RUL Use the ASAP rule for PState and WState. See Process PState and WState
Attributes on page 5-8.
