IBM Tivoli Composite Application Manager for Application Diagnostics, Version 188.8.131.52
Application Server attributes
The Application Server attributes provide the status and summary data for a specific WAS instance.
The attributes provide performance data for the WAS runtime (JVM memory), 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 WAS 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 Tivoli Enterprise 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.
For information about WebSphere PMI metrics, see WebSphere PMI Attribute Mapping.
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. Format is 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. Format is 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.
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.
The length (in seconds) of the sampling interval. Format is 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). Format is positive integer.
JVM Memory Total (bytes)
The JVM total memory size (in bytes). Format is positive integer.
JVM Memory Used (bytes)
The JVM used memory size (in bytes). Format is positive integer.
The name of the system on which the server is running. The value format is an alphanumeric string, with a maximum of 256 characters.
The name of the server subnode. Alphanumeric string.
The process identifier of the Java virtual machine. Format is 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. Format is 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 Tivoli Enterprise Management 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:
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 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. Alphanumeric string. Maximumight characters.
Indicates the mode of the WAS.
The name of the application server. Alphanumeric string.
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.
The status of the WebSphere application server. Valid values are Connected and Disconnected.
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. Format is positive integer.
The version of WAS. Alphanumeric string. Maximum characters.
