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.
- The attributes within this attribute group contain zeros for performance data if your site set configuration value Resource Data Collection Method to On Demand (for on-demand sampling) and you have not yet run applications that generate performance data. To report performance data in these attributes after installing and configuring the data collector, use the WebSphere administrative console to set the appropriate PMI instrumentation level.
- The Tivoli Enterprise Monitoring Agent is set by default to provide on-demand sampling; thus the attributes within this attribute group initially contain zeros until you select the workspace and then select it again later. Each time you select the workspace, these attributes are updated with the latest data.
For information about WebSphere PMI metrics, see WebSphere PMI Attribute Mapping.
The number of times a bean instance was activated during the interval. Format is positive integer.
The bean activations (per second) during the interval. Format is decimal (formatted to 3 decimal places).
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.
The average method response time for creates during the interval. Format is decimal (formatted to 3 decimal places).
The number of bean create calls during the interval. Format is positive integer.
The bean create calls (per second) during the interval. Format is decimal (formatted to 3 decimal places).
The number of times bean objects were destroyed by garbage collection during the interval. Format is positive integer.
The beans destroyed by garbage collection (per second) during the interval. Format is decimal (formatted to 3 decimal places).
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).
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).
The number of times bean objects were instantiated during the interval. Format is positive integer.
The number of times bean objects were instantiated (per second) during the interval. Format is decimal (formatted to 3 decimal places).
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.
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).
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).
The name of the system on which the server is running. The value format is an alphanumeric string, with a maximum of 256 characters.
The name of the server subnode. Alphanumeric string. Maximum 128 characters.
The number of times a bean instance was passivated during the interval. Format is positive integer.
The bean passivations (per second) during the interval. Format is decimal (formatted to 3 decimal places).
The bean remove calls (per second) during the interval. Format is decimal (formatted to 3 decimal places).
The average method response time for removes during the interval. Format is decimal (formatted to 3 decimal places).
The number of bean remove calls during the interval. Format is positive integer.
The number of requests during the interval. Format is positive integer.
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.
The name of the application server. Alphanumeric string.
Type
Indicates the WebSphere resource category, which is used by the agent to modify the Instrumentation Level for transaction data collection.
Whether this row is a summary row of statistical totals collected for all EJB containers. The valid values are No and Yes.
The total time used during the interval. Format is decimal (formatted to 3 decimal places).
The total time (in milliseconds) of bean create calls during the interval. Format is decimal (formatted to 3 decimal places).
The total time (in milliseconds) of method invocations during the interval. Format is decimal (formatted to 3 decimal places).
The total time (in milliseconds) of bean remove calls during the interval. Format is decimal (formatted to 3 decimal places).
