Application Server attributes
The attributes provide status and summary data.
The Application Server attributes provide the status and summary data for a specific WebSphere® Application Server instance.
The attributes provide performance data for the WebSphere Application Server runtime (Java™ virtual memory (JVM)), thread pools, HTTP sessions, and configuration parameters. They also provide some information from other attribute groups to give an overall view of the WebSphere Application Server. Use the application server attributes in situations to monitor the health and performance of a WebSphere Application Server.
The attributes within this group are used to build the WebSphere Application Server and the Pool Analysis Workspace workspaces.
- The attributes in this attribute group contain zeros for performance data if your site sets the 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 when you have installed and configured 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; this means the attributes in 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.
ASID The identifier (decimal) assigned to the address space running this servant region.
CPU Used (ms) Indicates the number of milliseconds the JVM CPU used during the interval. The valid format is a positive integer.
CPU Used (%) Indicates the percentage of the JVM CPU used during the interval. For UNIX users, this attribute has a meaningful value only if the Tivoli® Enterprise Monitoring Agent is running with superuser authority. The valid format is a decimal (formatted to 1 decimal place).
Platform CPU Used (ms) Indicates the number of milliseconds the host platform (OS) CPU used during the interval. This feature does not apply to the z/OS® platform.
Garbage Collection Monitoring The monitoring level for garbage-collection data. Valid values are Disabled and Enabled.
Instrumentation Level The JVM instrumentation level. 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 sampling interval. The valid format is a positive integer.
JVM Memory Free (Kbytes) The JVM free memory size in Kbytes.
JVM Memory Total (Kbytes) The JVM total memory size in Kbytes.
JVM Memory Used (Kbytes) The JVM used memory size in Kbytes.
JVM Memory Free (bytes) The JVM free memory size (in bytes). The valid format is a positive integer.
JVM Memory Total (bytes) The JVM total memory size (in bytes). The valid format is a positive integer.
JVM Memory Used (bytes) The JVM used memory size (in bytes). The valid format is a positive integer.
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.
Process ID The process identifier of the Java virtual machine. The valid format is a positive integer.
Request Data Monitoring Level The monitoring level for request data stored by the Data Collector. Valid values are Disabled, Level1 edge request data, such as servlets and JSPs are displayed), and Level2 (nested request data such as JDBC and JMS requests are also displayed).
Request Data Sampling Rate (%) The percentage of Level1 requests (that is, edge requests) being sampled. The valid format is a positive integer.
Resource Data Monitoring The monitoring level for resource (that is, PMI) data stored by the Data Collector. Valid values are Disabled and Enabled.
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 Instance Name The name of the WebSphere Application Server. This is a logical grouping of one or more server instances (called a "generic server" or "cluster") any one of which can run an application. The valid format is an alphanumeric string, with a maximum of eight characters.
Server Mode Indicates the mode of the WebSphere Application Server.
Server Name The name of the application server. The valid format is an alphanumeric string, with a maximum of 256 characters.
Server Type The type of the WebSphere Application Server. Valid values are Unknown, AppServer, AdminServer, NodeAgent, JMSServer, DeploymentManager, ManagedProcess, and UnManagedProcess.
Server Subnode Name Indicates the sub node name of the application server.
Start Date and Time The date and time when the WebSphere Application Server started. The valid format is a timestamp. 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.
Status The status of the WebSphere Application Server. Valid values are Connected and Disconnected.
Summary Indicates that this row is a summary row of statistical totals for all rows.
System Paging Rate (Kbytes/sec) The system paging rate in kilobytes per second during the interval. The valid format is a positive integer.
Version The version of WebSphere Application Server. The valid format is an alphanumeric string, with a maximum of 8 characters.
