Servlets JSPs attributes
The attributes provide servlet JSPs information.
The Servlets JSPs attributes provide performance information for servlets and Java™ server pages (JSPs).
Examples of Servlets JSPs attributes include the average number of concurrent requests for a servlet and the amount of time it takes for a servlet to complete a request. Use the Servlets JSPs attributes in situations to monitor performance and the usage of servlets and JSPs.
The attributes within this group are used to build the Servlets/JSPs - Selected Web Application 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 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.
Average Concurrent Requests The average number of concurrent requests for the servlet or JSP during the interval. The valid format is a decimal (formatted to three 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 time (in milliseconds) it took the servlet to perform a task during the interval. The valid format is a decimal (formatted to three decimal places).
Response Time Count The count of times that were averaged for Average Response Time. The valid format is a 4-byte integer. If the number is too big to be stored, a value of -2 is used.
Enterprise Application Name The name of the Enterprise application. The valid format is an alphanumeric string, with a maximum of 128 characters.
Error Count The number of errors or exceptions that have occurred in the servlet during the interval. The valid format is a positive integer.
Error Rate (per sec) The servlet exceptions or errors (per second) since the previous sample. The valid format is a decimal (formatted to three decimal places).
Instrumentation Level The instrumentation level for this servlet. For WebSphere Version 6 or later, 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. The valid format is a positive integer.
Node Name The name of the system on which the server is running. The value format is an alphanumeric string, with a maximum of 256 characters.
Origin Node The name of the server subnode. The valid format is an alphanumeric string, with a maximum of 128 characters.
Request Count The number of total requests for the servlet during the interval. The valid format is a positive integer.
Request Rate (per sec) The servlet requests (per second) since the previous sample. The valid format is a decimal (formatted to three decimal places).
Sample Date and Time The date and time the monitoring 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.
| 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. The valid format is an alphanumeric string, with a maximum of 256 characters.
Virtual Host Name The name of the virtual host. The valid format is an alphanumeric string, with a maximum of 64 characters.
Servlet/JSP Name The name of the current servlet or JSP. The valid format is an alphanumeric string, with a maximum of 128 characters.
Date and Time the Servlet Was Loaded The date and time when the servlet was loaded.
JSP Path Name The name of the JSP path. The valid format is an alphanumeric string, with a maximum of 128 characters.
Total (ms) The total time (in milliseconds) used during the interval. The valid format is a decimal (formatted to three decimal places).
Type Whether this entry represents a servlet or Java server page (JSP). The valid values are Servlet and JSP.
Web Application Archive The name of the web application WAR file. The valid format is an alphanumeric string, with a maximum of 128 characters.
Set Instrumentation Level Type The WebSphere resource category, which is used by the agent to modify the Instrumentation Level for transaction data collection. Valid values are: ORBThreadPool, HTTPSession, DBPool, Servlet, Transaction, ObjectPool, EJB, EJBMethod, AllResources, JVMMemory, ThreadPool, WCThreadPool, WebApplicationSubModule, DynamicCache, J2CPool, ORB, WLM, ServletSessions.
