IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

EJB Containers attributes

The EJB Containers attributes provide aggregated information for each defined EJB container that aggregates bean performance data for all Enterprise beans deployed to that container.

The attributes also provide aggregated information for the application server that aggregates bean performance data for all Enterprise beans deployed to the application server. These attributes provide load values, response times, and lifecycle activities for Enterprise beans. Use the EJB Containers attributes in situations to monitor application server load and resource usage.

The attributes within this group are used to build the EJB Containers workspace.

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

Activate Count

The number of times a bean instance was activated during the interval. Format is positive integer.

Activation Rate (per sec)

The bean activations (per second) during the interval. Format is decimal (formatted to 3 decimal places).

Active Method Count

The average number of bean methods concurrently active 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.

Average Concurrently Live Beans

The average number of bean objects concurrently live during the sampling 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.

Average Concurrently Ready Beans

The average number of beans concurrently active during the last 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.

Create Average Time (ms)

The average method response time for creates during the interval. Format is decimal (formatted to 3 decimal places).

Create Count

The number of bean create calls during the interval. Format is positive integer.

Creation Rate (per sec)

The bean create calls (per second) during the interval. Format is decimal (formatted to 3 decimal places).

Destroy Count

The number of times bean objects were destroyed by garbage collection during the interval. Format is positive integer.

Destruction Rate (per sec)

The beans destroyed by garbage collection (per second) during the interval. Format is decimal (formatted to 3 decimal places).

Entity Bean Load Count

The number of times an entity bean data was loaded during the interval. Format is positive integer.

Entity Bean Load Rate (per sec)

The number of entity beans (per second) that were loaded during the interval. Format is decimal (formatted to 3 decimal places).

Entity Bean Store Count

The number of times entity bean data was written to the database during the interval. Format is positive integer.

Entity Bean Store Rate (per sec)

The entity bean stores (per second) during the interval. Format is decimal (formatted to 3 decimal places).

Instantiate Count

The number of times bean objects were instantiated during the interval. Format is positive integer.

Instantiation Rate (per sec)

The number of times bean objects were instantiated (per second) during the interval. Format is decimal (formatted to 3 decimal places).

Instrumentation Level

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

Interval (sec)

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

Method Average Response Time (ms)

The average response time (in milliseconds) on remote interface methods for all beans during the interval. Format is decimal (formatted to 3 decimal places).

Method Invocation Count

The number of method invocations during the interval. Format is positive integer.

Method Invocation Rate (per sec)

The rate of invocations (per second) during the interval. Format is decimal (formatted to 3 decimal places).

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. Maximum 128 characters.

Passivate Count

The number of times a bean instance was passivated during the interval. Format is positive integer.

Passivation Rate (per sec)

The bean passivations (per second) during the interval. Format is decimal (formatted to 3 decimal places).

Removal Rate (per sec)

The bean remove calls (per second) during the interval. Format is decimal (formatted to 3 decimal places).

Remove Average Time (ms)

The average method response time for removes during the interval. Format is decimal (formatted to 3 decimal places).

Remove Count

The number of bean remove calls during the interval. Format is positive integer.

Request Count

The number of requests during the interval. Format is positive integer.

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 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 collected for all EJB containers. The valid values are No and Yes.

Total (ms)

The total time used during the interval. Format is decimal (formatted to 3 decimal places).

Total Create (ms)

The total time (in milliseconds) of bean create calls during the interval. Format is decimal (formatted to 3 decimal places).

Total Method Invocation (ms)

The total time (in milliseconds) of method invocations during the interval. Format is decimal (formatted to 3 decimal places).

Total Remove (ms)

The total time (in milliseconds) of bean remove calls during the interval. Format is decimal (formatted to 3 decimal places).
