WebSphere Liberty Servlets Test

For each servlet of the web application deployed on the target IBM WebSphere Liberty server, this test reports the rate at which each servlet was hit and the maximum time taken by each servlet to respond to user requests. In addition, this test reports the number of hits to each servlet. Using this test, administrators can figure out the servlet that has garnered the maximum number of hits and the servlet that took too long to respond to requests.

Target of the test : An IBM WebSphere Liberty

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each web application:servlet deployed on the target IBM WebSphere Liberty server being monitored.

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

Port

The port number at which the specified host listens.

Service URL Path

For the eG agent to collect metrics from the target IBM WebSphere Liberty server, the local connector should be enabled on the target server. Once the connector is enabled, a com.ibm.ws.jmx.local.address file will be created in the ${server.output.dir}/logs/state folder. The eG agent uses this file to connect to the target server and collect the required metrics from it. Therefore, specify the exact path to this file in the Service URL text box. For example, in case of Windows environments, the Service URL Path can be C:\wlp\usr\servers\server1\logs\state and in case of Linux environments, the Service URL Path can be /opt/wlp/ur/servers/server1/logs/state.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Requests

Indicates the number of requests(hits) to access this servlet.

Number

Compare the value of this measure across the servlets to figure out the servlet to which maximum number of requests were made.

Request rate

Indicates the rate at which this servlet was hit.

Requests/sec

 

Average response time

Indicates the average time taken by this servlet to respond to requests.

Milliseconds

Compare the value of this measure across servlets to figure out the servlet that is taking too long to respond.
