Queue attributes
The attributes provide aggregated information about the point to point messaging.
The Queue attributes within this group are used to build the Destinations 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.
- Themonitoring 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.
- Attributes in this group are only provided for WebSphere Application Server Version 6 or later.
Aggregate Message Wait Time The time spent by messages in the bus at consumption. If this time is not what was expected, view the message using the admin console to decide what action needs to be taken. The valid format is a positive integer.
Assured Persistent Messages Consumed The number of assured persistent messages consumed, for the lifetime of this messaging engine. The valid format is a positive integer.
Assured Persistent Messages Produced The number of assured persistent messages produced, for the lifetime of this messaging engine. The valid format is a positive integer.
Available Message The number of messages available for a queue for consumption. If this number is close to the destination high messages value, review the high messages value. The valid format is a positive integer.
Best Effort Non-persistent Messages Consumed The number of best effort non-persistent messages consumed, for the lifetime of this messaging engine. The valid format is a positive integer.
Best Effort Non-persistent Messages Produced The number of best effort non-persistent messages produced, for the lifetime of this messaging engine. The valid format is a positive integer.
Express Non-persistent Messages Consumed The number of express non-persistent messages consumed, for the lifetime of this messaging engine. The valid format is a positive integer.
Express Non-persistent Messages Produced The number of express non-persistent messages produced, for the lifetime of this messaging engine. The valid format is a positive integer.
Instrumentation Level The instrumentation level for the database connection pool for the data source. Valid values are None, Low, Medium, High, Basic, Extended, All, Custom, and Maximum. Blank if no instrumentation level is set.
Interval (sec) The length (in seconds) of the sampling interval. The valid format is a positive integer.
Local Consumer The number of currently attached local consumers. The valid format is a positive integer.
Local Consumer Attaches The number of times an attachment has been made to this queue by local consumers. The lifetime of this value is the lifetime of the messaging engine. The valid format is a positive integer.
Local Message Wait Time The time spent by messages on this queue at consumption. If this time is not what was expected, view the message using the admin console to decide what action needs to be taken. The valid format is a positive integer.
Local Oldest Message Age The longest time any message has spent on this queue. If this time is not what was expected, view the message using the admin console to decide what action needs to be taken. The valid format is a positive integer.
Local Producer The number of currently attached local producers. The valid format is a positive integer.
Local Producer Attaches The number of times an attachment has been made to this queue by local producers. The lifetime of this value is the lifetime of the messaging engine. The valid format is a positive integer.
Messaging Engine Name The name of the message engine. The value format is an alphanumeric string, with a maximum of 256 characters.
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. The valid format is an alphanumeric string, with a maximum of 128 characters.
Queue Name The name of the queue. The value format is an alphanumeric string, with a maximum of 256 characters.
Reliable Non-persistent Messages Consumed The number of reliable non-persistent messages consumed, for the lifetime of this messaging engine. The valid format is a positive integer.
Reliable Non-persistent Messages Produced The number of reliable non-persistent messages produced, for the lifetime of this messaging engine. The valid format is a positive integer.
Reliable Persistent Messages Consumed The number of reliable persistent messages consumed, for the lifetime of this messaging engine. The valid format is a positive integer.
Reliable Persistent Messages Produced The number of reliable persistent messages produced, for the lifetime of this messaging engine. The valid format is a positive integer.
Report Enabled Messages Expired The number of report enabled messages that expired while on this queue. The valid format is a positive integer.
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.
Summary Whether this row is a summary row of statistical totals for all rows. Valid values are No and Yes.
Total Messages Consumed The total number of messages consumed from this queue, for the lifetime of this messaging engine. The valid format is a positive integer.
Total Messages Produced The total number of messages produced to this queue, for the lifetime of this messaging engine. The valid format is a positive integer.
Unavailable Message The number of messages locked or uncommitted. This means messages that have been added or removed but the transaction has not been committed yet. If this number is high, check which messages are locked and why.
