WMQ Client Link Communications attributes
The attributes provide WMQ client link communications information.
The WMQ Client Link Communications attributes display aggregated information for all the clients of WMQ Queue Managers that are or have been connected to this application server.
The attributes within this group are used to build the WMQ Client Link Communications 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 reselect it later. Each time you reselect the workspace, these attributes are updated with the latest data.
- Attributes in this group are only provided for WebSphere Application Server Version 6.0 or later.
API Calls Serviced The number of MQ API call requests serviced on behalf of WMQ JMS clients. The valid format is a positive integer.
Batches Sent The number of batches of messages sent to network attached WMQ JMS clients. The valid format is a positive integer.
Clients Attached The current number of WMQ JMS clients attached to this application server. The valid format is a positive integer.
Comms Errors The number of errors that have caused connections to WMQ JMS clients to be dropped. The valid format is a positive integer.
Instrumentation Level The instrumentation level for the WMQ client link communications. For WebSphere Version 6 or later, the valid values are None, Basic, Extended, All, Custom. Blank if no instrumentation level is set.
Interval (sec) The length (in seconds) of the sampling interval. The valid format is a positive integer.
Messages Received The number of messages received from network attached WMQ JMS clients. The valid format is a positive integer.
Messages Sent The number of messages sent to network attached WMQ JMS clients. 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.
Reads Blocked The number of read operations that could not be completed immediately. This number can be used as an indicator of network congestion when communicating with WMQ JMS clients. The valid format is a positive integer.
Received (bytes) The number of bytes of data received from network attached WMQ JMS clients. This includes bytes of message data as well as bytes of data used to control the flow of messages. 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.
Sent (bytes) The number of bytes of data sent to network attached WMQ JMS clients. This includes bytes of message data as well as bytes of data used to control the flow of messages. The valid format is a positive integer.
Server Name The name of the application server. The valid format is an alphanumeric string, with a maximum of 256 characters.
Writes Blocked The number of write operations that could not be completed immediately. This number can be used as an indicator of network congestion when communicating with WMQ JMS clients. The valid format is a positive integer.
