Description

Use the ADVISE PERFORMANCE REPORT command to produce Performance Manager reports. The Performance Manager can generate reports using either daily or historical data. The following section describes the qualifiers you can use with the ADVISE PERFORMANCE REPORT command to control report generation. The report keywords are as follows:

ANALYSIS
Consists of conclusions, conditions, and evidence for each rule that fired for each node and includes cluster-wide conclusions for a cluster system.
BRIEF_ANALYSIS
A brief version of the analysis report consisting of a one-line synopsis of each conclusion.
HISTOGRAMS
Consists of chronological charts that show peak resource usage. The Performance Manager produces a report containing separate histograms for CPU utilization, number of disk I/Os, number of terminal I/Os, memory usage, node status information, and, if you include the /IMAGE qualifier, an image residence time histogram. Use of the /IMAGE qualifier it limited to the DCL command interface.
PERFORMANCE_EVALUATION
TABULAR[=(FINAL,INTERVAL,BYCLUSTER,BYNODE)
Contains an overview of the system activity on a per node basis, or cluster-wide. Subsections of this report can be selected or omitted with the /SECTION qualifier.

The Tabular report can be presented in the following ways:

FINAL	Each Tabular report section is presented with statistics representing the whole time period.
INTERVAL	Each Tabular report section is presented for each reporting interval. By default the reporting interval is the same as the recording interval, however you can specify the reporting interval with the /INTERVAL qualifier.
BYCLUSTER	Each Tabular report section is presented in a cluster-wide format. The configuration section is not available in the cluster-wide format.
BYNODE	Each Tabular report section is presented in a cluster-wide format with the by-node detail included. The configuration section is not available in the cluster-wide format.

If both BYNODE and BYCLUSTER are omitted, the Tabular report sections are presented on a node by node basis, and not on a cluster-wide basis. By default, if none of the above options are specified, FINAL is assumed.

Using BYCLUSTER or BYNODE presents a different output format than FINAL or INTERVAL. For example, the following commands produce different output formats:

ADVISE PERF REPORT TABULAR/SECTION=ALL
ADVISE PERF REPORT TABULAR=BYCLUSTER/SECTION=ALL
