IBM Tivoli Composite Application Manager for Application Diagnostics, Version 126.96.36.199
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.
- The attributes within this attribute group contain zeros for performance data if your site set 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 after installing and configuring 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; thus the attributes within 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.
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.
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).
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.
The length (in seconds) of the sampling interval. Format is positive integer.
The name of the system on which the server is running. Alphanumeric string.
The name of the server subnode. Alphanumeric string.
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.
The name of the application server. Alphanumeric string.
The number of servlets loaded during the interval. Format is positive integer.
The number of servlets reloaded during the interval. The valid format a positive integer.
Set Instrumentation Level
Indicates the WebSphere resource category, which is used by the agent to modify the Instrumentation Level for transaction data collection.
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.
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.
