IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

JDK - JVM attributes

The JDK - JVM attributes provide overall information about the Java Virtual Machine (JVM) that the J2SE application server is using. This includes the information of JVM name, version and uptime. 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.

Formatted Uptime

The time with a specific format during which the Java Virtual Machine is running (supported for JVM version 1.5 and higher). The format is DDd HHh MMm SSs; For example, 1d 2h 44m 23s.

Interval (sec)

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

JVM Name

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

JVM Vendor

The producer of the Java Virtual Machine (supported for JVM version 1.5 and higher). Format is alphanumeric string, with a maximum of 256 characters.

JVM Version

The version of the Java Virtual Machine (supported for JVM version 1.5 and higher). Format is alphanumeric string, with a maximum of 256 characters.

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.

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.

Start Time

The date and time when the Java Virtual Machine was started (supported for JVM version 1.5 and higher). The valid format is a 12-character 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.

Uptime

The amount of time (in seconds) the JVM has been running (supported for JVM version 1.5 and higher). Format is positive integer.
