Utilization data messages are continuously sent to Operations Sentinel based on the interval, in seconds, defined for the UTILIZATION_INTERVAL parameter in the configuration file. See Section 3. You can change the length of the interval by changing the time in the configuration file or by using the SAMPLE command. See Section 5. The utilization information is packaged into a single message packet. A description of the format and content of the utilization message follows:
hhmmss UTILIZATION DISPLAY: attribute-value-pair, ...
where:
hhmmss
is the time the message was sent.
attribute-value-pair
consists of an attribute name, an equal sign, and a numeric value (for example, PROCUSER=58). Each attribute value pair is separated from the next attribute value pair by a comma.
See the SP-AMS sample database MCPMon for the exact order of the attribute value pairs in the message.
If the interface software detects an error while collecting utilization data, the following message is displayed:
<<ASPO>>GETSTATUS ERROR ON UTILIZATION INQUIRY
If this happens, the utilization message is still sent to the Operations Sentinel server. However, some of the numeric values in the attribute value pairs may be blank.
Table 6–1 lists the utilization data message attribute names and their associated values.
Table 1. Utilization Data Message Attribute Names and Associated Values
