Workload Management Client attributes

The attributes provide workload management client information.

The Workload Management Client attribute group provides information about the client that initiates workload requests.

Workload management (WLM) optimizes the distribution of client processing tasks. Incoming work requests are distributed to the application servers, enterprise beans, servlets, and other objects that can most effectively process their requests. Workload management also provides failover when servers are not available, improving application availability. In a WebSphere® Application Server environment, you implement workload management by using clusters, transports, and replication domains.

The attributes within this group are used to build the Workload Management workspace.

Notes:
  • 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 later. Each time you select the workspace, these attributes are updated with the latest data.

Client Cluster Update Rate (per sec) The rate (per second) at which times this client has received new server cluster information during the sampling interval. Use this metric to determine how often cluster information is being propagated. The valid format is a decimal (formatted to 3 decimal places).

Client Cluster Updates The number of times initial or updated server cluster data is sent to a WLM-enabled client from a server cluster member. Use this metric to determine how often cluster information is being propagated. The valid format is a positive integer.

Client Response Time (ms) The response time (in milliseconds) for IIOP requests sent by a client. This response time is calculated based on the time the client sends the request to the time the server sends the reply. The valid format is a decimal (formatted to 3 decimal places).

Instrumentation Level The instrumentation level for the WLM client. 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.

Node Name The name of the system on which the server is running. The valid format is an alphanumeric string, with a maximum of 128 characters.

Origin Node The name of the server subnode. The valid format is an alphanumeric string, with a maximum of 128 characters.

Outgoing Request Rate (per sec) The rate (per second) at which outgoing IIOP requests were being sent from this client to an application server during the sampling interval. The valid format is a decimal (formatted to 3 decimal places).

Outgoing Requests The number of outgoing IIOP requests being sent from this client to an application server. 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.

Table 1. 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 WebSphere 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.

Total Client Response (ms) The total response time (in milliseconds) for IIOP requests sent by a client. The valid format is a decimal (formatted to 3 decimal places).
