Container Transactions attributes
The attributes provide transaction information.
The Container Transactions attribute group provides performance information about transactions that run in each defined EJB container and an aggregated value for all transactions that run in the application server.
Use the Container Transactions attributes in situations to monitor transaction activity for each EJB container and for the application server. The attributes within this group are used to build the Container Transactions 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 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.

Global Transactions Involve Rate (per sec) The number of times (per second) global transactions were involved during the interval. The valid format is a positive integer.
Global Transactions Involved The number of global transactions that were involved at the server during the interval, including those that were begun or imported. The valid format is a positive integer.
Global Transactions Rolled Back The total number of global transactions that were undone because they could not complete during the interval. The valid format is a positive integer.
Global Transactions Optimized The number of global transactions converted to single phase for optimization since the previous sample. The valid format is a 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.
Interval (sec) The length (in seconds) of the interval. The valid format is a positive integer.
Local Transaction before Completion Duration (ms) The average duration before completion for local transactions during the interval. The valid format is a decimal (formatted to 3 decimal places).
Local Transaction Commit Duration (ms) The average duration for commit for local transactions during the interval. The valid format is a decimal (formatted to 3 decimal places).
Local Transaction Commit Rate (per sec) The number of local transactions (per second) committed during the interval. The valid format is a decimal (formatted to 3 decimal places).
Local Transaction Duration (ms) The average duration (in milliseconds) of local transactions during the interval. The valid format is a decimal (formatted to 3 decimal places).
Local Transaction Rollback Rate (per sec) The number of times (per second) that local transactions were undone because they could not be completed during the interval. The valid format is a decimal (formatted to 3 decimal places).
Local Transaction Timeout Rate (per sec) The number of local transactions that timed out per second during the interval. The valid format is a decimal (formatted to 3 decimal places).
Local Transaction Timeouts The number of local transactions that timed out during the interval. The valid format is a positive integer.
Local Transactions Active The number of concurrently active local transactions running in the container during the interval. Local transactions involve a single resource manager. The valid format is a decimal (formatted to 3 decimal places).
Local Transactions Begin Rate (per sec) The number of times (per second) local transactions were started during the interval. The valid format is a positive integer.
Local Transactions Begun The number of local transactions begun at the server since the previous sample. The valid format is a positive integer.
Local Transactions Committed The number of local transactions committed during the interval. The valid format is a positive integer.
Local Transactions Rolled Back The number of local transactions that were undone during the interval. The valid format is a positive integer.
Node Name The name of the system on which the server is running. The valid format is an alphanumeric string, with a maximum of 256 characters.
Origin Node The name of the server subnode. The valid format is an alphanumeric string, with a maximum of 128 characters.
Sample Date and Time The date and time the monitoring 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:
| 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. The valid format is an alphanumeric string, with a maximum of 256 characters.
Set Instrumentation Level Type Indicates the WebSphere resource category, which is used by the agent to modify the Instrumentation Level for transaction data collection.
