IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1

Web Applications attributes

Use the Web Applications attributes to create situations that monitor Web application performance and application server loads.

The Web Applications attributes provide aggregated information for each Web application and for the application server running that application. These performance data describe all servlets and JSPs deployed to that Web application as well as performance data for all servlets and JSPs running in the application server. Examples include the number of loaded servlets and JSPs and total requests. The attributes within this group are used to build the Web Applications workspace.

For information about WebSphere PMI metrics, see WebSphere PMI Attribute Mapping.

Average Concurrent Requests

The average number of concurrent requests for servlets and JSPs during the interval. Format is decimal (formatted to 3 decimal places). This value is an average of several values collected over an interval. The interval can be either between this time and the previous time you activated this workspace, or fixed (normally 60 seconds), depending on the configuration of the monitoring agent.

Average Response Time (ms)

The average time (in milliseconds) required for a servlet to perform a task during the interval. Calculated by dividing the total responses by Request Count; if Request Count

is zero, this value is set to blank. Format is decimal (formatted to 3 decimal places).

Enterprise Application Name

The name of the Enterprise application. Alphanumeric string.

Error Count

The number of errors or exceptions that have occurred in the servlet. Format is positive integer.

Error Rate (per sec)

The servlet exceptions or errors (per second) for the interval since the previous sample. Format is decimal (formatted to 3 decimal places).

Instrumentation Level

The Web instrumentation level for this Web application. For WebSphere 5, the valid values are None, Low, Medium, High and Maximum; 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. Format is positive integer.

Node Name

The name of the system on which the server is running. Alphanumeric string.

Origin Node

The name of the server subnode. Alphanumeric string.

Request Count

The number of total requests for the servlet during the interval. Format is positive integer.

Request Rate (per sec)

The servlet requests (per second) for the interval since the previous sample. Format is decimal (formatted to 3 decimal places).

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 Name

The name of the application server. Alphanumeric string.

Servlets Loaded

The number of servlets loaded during the interval. Format is positive integer.

Servlets Reloaded

The number of servlets reloaded during the interval. The valid format a positive integer.

Set Instrumentation Level

Type

Indicates the WebSphere resource category, which is used by the agent to modify the Instrumentation Level for transaction data collection.

Subinstrumentation Level

The subinstrumentation level for the Web application's servlet submodule. For WAS 5 the valid values are None, Low, Medium, High, and Maximum.

Subinstrumentation Level is not supported in WAS 6.0 or higher. The Tivoli Enterprise Monitoring agent uses the Instrumentation Level instead.

Summary of All Applications

Whether this row is a summary row of statistical totals for all Web applications executed during the interval. The valid values are Yes and No.

Total (ms)

The total time used during the interval. Format is decimal (formatted to 3 decimal places).

Web Application Archive

The name of the Web application WAR file. Alphanumeric string.
