IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

Container Object Pools attributes

Use the Container Object Pools attributes in situations to monitor the effectiveness of the object cache and of resource usage.

These attributes provide aggregated information for each defined EJB container that aggregates bean object pool performance for all Enterprise beans deployed to that container and aggregated information for the application server that aggregates bean object pool performance data for all Enterprise beans deployed to the application server. The attributes within this group are used to build the Container Object Pools workspace.

For information about WebSphere PMI metrics, see WebSphere PMI Attribute Mapping.

Average Objects Discarded

The average number of objects discarded each time the bean object pool was emptied of idle objects during the interval. Format is decimal (formatted to 3 decimal places).

Average Objects in Pool

The average number of objects in the bean object pool during the interval. Format is decimal (formatted to 3 decimal places). This value is an average of several values collected over an interval. The interval can be either between this time and the previous time you activated this workspace, or fixed (normally 60 seconds), depending on the configuration of the monitoring agent.

Discard Count

The number of times the object returned to the bean-object pool was discarded because the bean object pool was already full during the interval. Format is positive integer.

Discard Rate (per sec)

The bean object pool discard rate (per second) for the interval since the previous sample. Format is decimal (formatted to 3 decimal places).

Drain Count

The number of times the bean object pool was found idle and an attempt was made to remove idle objects during the interval. Format is positive integer.

Drain Rate (per sec)

The number of times (per second) that the bean object pool was found idle during the interval since the previous sample. Format is decimal (formatted to 3 decimal places).

Find Count

The number of times a retrieval call found an available object in the bean object pool during the interval. Format is positive integer.

Find Rate (per sec)

The availability of bean object pool retrievals (per second) for the interval since the previous sample. Format is decimal (formatted to 3 decimal places).

Get Count

The number of calls retrieving an object from the bean object pool during the interval. Format is positive integer.

Get Rate (per sec)

The number of bean objects retrieved (per second) for the interval since the previous sample. Format is decimal (formatted to 3 decimal places).

Interval (sec)

The length (in seconds) of the interval. Format is positive integer.

Instrumentation Level

The instrumentation level for this container. For WebSphere 6 or higher, the valid values are None, Basic, Extended, All, Custom. Blank if no instrumentation level is set.

Node Name

The name of the system on which the server is running. The value format is an alphanumeric string, with a maximum of 256 characters.

Origin Node

The name of the server subnode. Alphanumeric string.

Return Count

The number of calls returning an object to the bean object pool during the interval. Format is positive integer.

Return Rate (per sec)

The bean objects returned (per second) for the interval since the previous sample. Format is decimal (formatted to 3 decimal places).

Sample Date and Time

The date and time the Tivoli Enterprise Management Agent collected the data. The valid format is a 12-character timestamp. For the STR and SCAN functions, the format is MM/DD/YY HH:MM:SS; the following table shows the values contained in this character string:


Format of the 12-character timestamp

Character String Meaning
MM Month
DD Day
YY Year
HH Hour
MM Minute
SS Second

Example: 09/13/06 18:32:03 indicates the data was collected on September 13, 2006, at 18:32:03.

This attribute was designed for logging and reporting data-collection times rather than for creating situations. To specify a time and date for comparison and testing, use attributes from the Universal Time or Local Time groups.

Server Name

The name of the WebSphere application server. Alphanumeric string.

Set Instrumentation Level

Type

Indicates the WebSphere resource category, which is used by the agent to modify the Instrumentation Level for transaction data collection.

Summary of All Containers

Whether this row is a summary row of statistical totals aggregated over all bean object pools in the application server. Valid values are No and Yes.
