System service analysis requires that system service data be
    gathered. Use the SET SERVICES command in the Collector to gather
    system service data.

    The PLOT and TABLUATE commands in the Analyzer accept one
    datakind qualifier to analyze system service usage:

    /SERVICES              Tallies system service call counts

    The PLOT and TABULATE commands accept several nodespecs:

    SYSTEM_SERVICE BY SERVICE
    SERVICE service-name

    The SET FILTER Analyzer command accepts one filter specification
    to analyze system service usage:

    SERVICE=service-name
