Overview of IMS Monitor reports

A list of reports available from data collected by the IMS Monitor, together with the principal performance data they contain, is shown in the following table.

Related reading: For a description of those reports marked DB, see DB Monitor reports.

The order of the reports listed in the table matches the sequence of the output from the IMS Monitor Report Print program. The duration of a monitoring snapshot might not include certain events necessary for an individual report, in which case only report headings or partial data are produced.

The majority of the data items in IMS Monitor reports are elapsed times. These are normally expressed in microseconds. An entry of 1876534 is 1.876534 seconds or 1876 milliseconds. Any times that do not follow this convention show the unit of measure on the report.

You can also find counts of events under the heading OCCURRENCES, and some figures that represent the number of bytes.
