WebSphere Liberty Topics Test
This test auto-discovers the topics of the applications deployed on the target IBM WebSphere Liberty server and reports the maximum configured size of each topic. This test also helps administrators to figure out whether get operations are allowed on each topic. Using this test, administrators can figure out the topic that is latent and is unable to process I/O requests quickly!
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 topic on the target IBM WebSphere Liberty server being monitored.
| 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. |
| Measurement | Description | Measurement Unit | Interpretation | ||||||
|---|---|---|---|---|---|---|---|---|---|
|
Send allowed |
Indicates whether/not get operations were allowed in this topic. |
|
The values reported by this measure and its numeric equivalents are mentioned in the table below:
Note: By default, this measure reports the Measure Values listed in the table above to indicate get operations were allowed in this topic. The graph of this measure however, represents the status of a server using the numeric equivalents only - 0 or 1. |
||||||
|
Depth |
Indicates the number of outstanding read/write(I/O) requests to this topic. |
Number |
If the value of this measure keeps increasing steadily and significantly for each topic, it could indicate that the topic is latent, and is unable to process I/O requests quickly. The value of this measure therefore should be low at all times. |
||||||
|
Maximum topic size |
Indicates the maximum configured size of this topic. |
Number |
