IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

JDK - Threading attributes

The JDK - Threading attributes provide overall information about the threads, including peak thread and daemon thread. A thread is the basic unit of program execution in the Java Virtual Machine. A process can have several threads running concurrently, each performing a different job. When a thread has finished its job, it is suspended or destroyed. The data for attributes is gathered from JVM MBeans, which are supported in JVM version 1.5 and higher. No data will be available for JVM with versions lower than 1.5.

The attributes within this group are used to build the JVM Statistics workspace.

Current Thread CPU Time

The CPU time (in seconds) used to process the current thread (supported for JVM version 1.5 and higher). Format is positive integer.

Current Thread User Time

The user time (in seconds) used for the current thread (supported for JVM version 1.5 and higher). Format is positive integer.

Daemon Thread Count

The number of threads which run unattended to perform continuous or periodic functions (supported for JVM version 1.5 and higher). Format is positive integer.

Interval (sec)

The length of the interval in seconds (supported for JVM version 1.5 and higher). Format is positive integer.

Node Name

The name of the system on which the server is running (supported for JVM version 1.5 and higher). Format is alphanumeric string, with a maximum of 256 characters.

Origin Node

The name of the server subnode (supported for JVM version 1.5 and higher). Format is alphanumeric string, with a maximum of 128 characters.

Peak Thread Count

The maximum number of threads executed in the Java Virtual Machine (supported for JVM version 1.5 and higher). Format is positive integer.

Sample Date and Time

The date and time that the monitoring agent collected data (supported for JVM version 1.5 and higher). 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 Name

The name of the J2EE application server (supported for JVM version 1.5 and higher). Format is alphanumeric string, with a maximum of 256 characters.
