Viewing Completed PMUs

Access the Completed PMUs page (PeopleTools, Performance Monitor, History, Completed PMUs).

Note: The search result of completed PMUs includes history information collected by agents even if they are currently marked inactive.

Note: If a "clone table" warning appears at the top of the page, the archive program is either currently running or has abnormally terminated. If this is the case, all new incoming information that is being sent to the monitoring system is currently being inserted into the clone tables. New performance data is not inserted into the current data tables until the archive program finishes successfully.

Entering Search Criteria

Before you can view information about completed PMUs, you need to enter criteria so that you can locate the appropriate completed PMUs.

Use the Advanced Search link to expose all search criteria.

The maximum rows that are returned by the search depends on the value in the Search Row Limit field on the Global Administration page.

See Setting Global System Options.

System ID

Identifies each monitored system. PeopleSoft automatically generates this value incrementally. System definitions are created automatically when the first agent of a monitored system registers with the monitoring system.

Database Name

The name of the PeopleSoft application database running on the monitored system. The monitoring system automatically inserts this value when it recognizes and creates a monitored system.

User ID

If you want information for a particular user, enter the user ID of the user for which you want to track completed PMUs.

This field prompts against the PSPMOPRDEFN table.

Process ID

Enables you to search completed PMUs by the process ID.

Performance Trace Name

If a user has launched a performance trace in the Performance Trace Console, the system labels every PMU that is generated in a business process with a performance trace name. Select the appropriate trace name to view its results.

The Performance Trace Name field prompts against the PSPMPERFTRACE table, which the Lookup program (PSPM_LOOKUP) populates.

Component

If you want information for a particular component, enter the name of the component for which you want to track completed PMUs.

This field prompts against the PSPMPNLGRPDEFN table.

Note: Searching on a component is equivalent to searching on Context 1 for application server PMUs.

Market

Enter the market that is associated with the component.

PMU Definition Set

Indicates the set to which the PMU definition belongs. A PMU definition set is similar to a message set.

This is required if you want to generate metric and duration charts.

PMU Identifier

Identifies the PMU definition within a PMU definition set.

This is required if you want to generate metric and duration charts.

Context 1, 2, 3

PMU metrics contain data that is specific to that PMU. Context values, on the other hand, are common to the entire user request or a specific tier. For example, the component name is stored in a context. The system uses contexts to "flatten" a PMU tree. For example, you do not have to navigate up from a SQL PMU to an ICPanel PMU to see what component generated that SQL statement. In some cases, PMU types are shared across different user request types. In such cases, the label for the PMU will be generic. Use the Context Help button to view the context definitions for a PMU set ID and ID that you've entered.

PMU Status

Displays the PMU status.

See Completed PMU Status.

Top Instance

Each PMU that is reported by an agent has a unique instance ID. The instance identifier of the first PMU generated by a particular user request is the top instance. The value of the top instance is then stored with every child PMU within a request. The top instance is the associating value for all PMUs that are generated by the same user request.

Statement Number

This search field applies only when you are searching for PeopleCode SQL PMUs, which are PMU 406 (PeopleCode SQL Execute) and PMU 407 (PeopleCode BuiltIn SQL Execute). The Context 2 field contains the PeopleCode program name andMetric 2 contains the statement number in the PeopleCode where the SQL was executed.

To search by statement number, you must enter the following search criteria: PMU Definition Set = 1, PMU ID = 406 or 407, and Context 2 must have the name of a PeopleCode program.

From Date/Time To Date/Time

Specify a range of time in which the system should search for completed PMUs.

The system searches on the monitor date and time, not the agent date and time.

Duration

Specify criteria that is related to the duration of a PMU in milliseconds.

Domain Name

Select the application server domain to generate the PMUs.

Domain Host/Port

Select the name and port number of the server machine on which the domain that generated the PMU resides.

Agent Identifier

Identify the specific agent that monitored a PMU.

Agent Type

Identify the type of agent that monitored a PMU.

Search

The Search button performs a search based on the search criteria that is defined on the page. If you want to view the most current information, use theRefresh button after running the initial search. If you clickSearch repeatedly, the system returns the same results from the same time range for each search.

Refresh

Updates the value in the To Time field to equal the current time and performs a search. This enables you to view the most current results of a search.

Working with Completed PMUs

At the bottom of the Completed PMUs page, the Completed PMUs grid contains the information that is related to the PMUs that are retrieved by your search criteria. The tabs in the Completed PMUs page are discussed in the following sections.

Summary

PMU

Indicates the name of the PMU. Click the PMU name to view the PMU Details page.

Duration

Indicates the duration of the PMU from start to finish in milliseconds.

Complete Tree

Click the tree icon to view the complete PMU tree, including all ancestor and descendant PMUs.

PMU Details

Provides further description of the PMU.

The details comprise contexts and metrics that are helpful for identifying the PMU. Each type of PMU displays a different set of details.

User

Indicates the user whose request triggered the PMU.

PMU Status

Displays the PMU status.

See Completed PMU Status.

Monitor Received Date/Time

Indicates when the monitor system received notification that a PMU had been started or updated.

Agent Start Date/Time

Indicates that time according to the agent clock that the last update was received.

Domain Name

Indicates the domain that handled the request that is associated with the PMU.

Identifiers

The Identifiers tab presents the following additional information.

PMU Set

Identifies the set to which the PMU ID belongs.

PMU ID

Identifies a PMU definition within a PMU set.

Agent ID

Identifies the agent that reported the PMU.

Process ID

The operating system process ID of the process that generated the PMU.

Instance

A unique identifier that is generated by the system for each PMU.

Parent Instance

The PMU that produced the PMU in this grid row.

Top Instance

Each PMU that is reported by an agent has a unique instance ID. The instance identifier of the first PMU that is generated by a particular user request is the top instance. The value of the top instance is then stored with every child PMU within a request. The top instance is the value that associates all PMUs that are generated by the same user request.

Contexts

The Contexts tab reveals the context definition and value that is associated with each PMU in the grid. To view the details of the contexts in a PMU, examine the context and PMU definitions.

This Description column shows data for the additional description value that is part of the incoming PMU. The description stores large character values and generally stores information that exceeds the 128–character limit of Metric 7 and the 254–character limit of the contexts.

See Context Definitions.

Metrics

The Metrics tab presents the metric values for all of the metrics that are defined for each PMU in the grid.

Metric information appears in a raw format. The values reflect exactly what is stored in the database.

See Metric Definitions.

Trees

The Trees tab enables you to view the PMU within the context of a PMU tree.

View Ancestors

Shows all parent PMUs for the selected PMU. This may be useful in determining the call tree of a child PMU.

Only direct ancestors appear; sibling PMUs do not appear.

View Descendants

Shows all child PMUs for the selected PMU. This may be useful in determining where the time is spent for a PMU.

Complete Tree

Displays the entire tree representing the user request. If verbose or debug filters are set, this tree may contain a large number of nodes and may take a significant amount of time to load.

Metric Charts

When your search criteria includes a PMU set and PMU identifier, all rows in the grid will be of the same type of PMU. In this case, the metric chart displays the metric values of the returned PMUs against one another. This enables you to track metrics over a period of time.

Image: Viewing a metric chart

This example illustrates the fields and controls on the Viewing a metric chart.

Viewing a metric chart

Numeric metrics may be of type Counter, Gauge, or Numeric Identifier. Numeric identifiers do not appear in charts. Gauges and counters do appear in charts, but the chart does not contain a sum value for gauges.

Use the View in Grid link to view the chart information in a grid so that you can download the information to an Microsoft Excel spreadsheet if needed.

Note: If the metrics of a PMU can't be charted, a message appears stating this fact.

Note: To view the metric chart, you must specify a PMU and PMU set ID as part of the search criteria. If you click this link when performance data for multiple PMUs appears, the system displays an error message.

Note: The data appearing on this chart is not manipulated by multipliers, if any are used.

See Metric Definitions.

Duration Charts

The duration charts show all durations for all PMUs appearing in the grid. The chart is time-based.

Image: Viewing a duration chart

This example illustrates the fields and controls on the Viewing a duration chart. You can find definitions for the fields and controls later on this page.

Viewing a duration chart

Use the View in Grid link to view the chart information in a grid so that you can download the information to an Microsoft Excel spreadsheet if needed.

Note: To view the duration chart, you must specify a PMU and PMU set ID as part of the search criteria. If you click this link when performance data for multiple PMUs appears, the system displays an error message.

Completed PMU Status

A completed PMU can be assigned one of the following statuses:

Status

Description

Success

The PMU finished successfully.

Failed

The PMU finished unsuccessfully.

Abort

Instrumentation code terminated a PMU due to an unexpected condition.
