You can use a servlet MXBean for web application monitoring
of the Liberty profile.
Performance data is available for each Servlet in the
Web Application. Each servlet has its own MXBean.
The
ObjectName for
identifying each servlet MXBean is:
WebSphere:type=ServletStats,name=<AppName>.<ServletName>
For
example:
WebSphere:type=ServletStats,name=snoop.Alpine Snoop Servlet
WebSphere:type=ServletStats,name=MyApp.MyServlet
This
MXBean is responsible for reporting
ServletStats for
each servlet. Following key data is available for
ServletStats MXBean:
- Request Count
- Response Time
- Servlet Name
- Application Name
- Counter definitions (Attributes to MXBean)
- AppName: Name of the application.
- ServletName: Name of the servlet.
- RequestCount: Number of hits to this servlet.
- ResponseTime: Average response time (nano-seconds).
- Description: Description of counter.
- RequestCountDetails: RequestCount details
including last time stamp.
- ResponseTimeDetails: ResponseTime details
including number of snapshot taken, min, max values and so on.
.
Management Interface
The management interface of web application monitoring is com.ibm.websphere.webcontainer.ServletStatsMXBean.
You can use the management interface to obtain a proxy object. See Liberty profile: Examples of accessing MBean attributes and operations.
For more information about the management interface, see the Java API document for the Liberty profile. The Java API documentation for each Liberty profile API is detailed in the Programming Interfaces (APIs) section of the information center, and is also available as a separate .zip file in one of the javadoc subdirectories of the ${wlp.install.dir}/dev directory.
