Monitoring WebSphere Application Server
After you install the Instana host agent, WebSphere Application Server sensor is automatically installed, but you need to configure as outlined in this topic. For more information, see Configuring. Then, you can view metrics that are related to WebSphere Application Server in the Instana UI.
Supported information
Supported operating systems
The supported operating systems of the WebSphere Application Server sensor are consistent with the host agent requirements. For more information, see the Supported operating systems section of the Windows, Unix, or Linux host agent documentation:

Supported tracing
For this technology, Instana supports tracing. For more information, see Instrumented frameworks and libraries.
To enable tracing for WebSphere on z/OS, complete the steps in the Instana on z/OS Tracing requirement.
Configuring
WebSphere server uses the embedded IBM J9 VM by default. For more information, see IBM J9 limitations.
The metrics are collected from Performance Monitoring Infrastructure (PMI) of WebSphere server. The required PMI data collection is enabled by default. That means if enable_pmi field is not set or set to true in the
agent configuration file <agent_install_dir>/etc/instana/configuration.yaml file, the PMI is enabled.
If enable_pmi is set the value as false, the PMI will not be enabled, and the original setting will not be changed.
The unit of poll_rate is second. The default value is 5.
See the following configuration example:
com.instana.plugin.websphere:
enable_pmi: false
poll_rate: 5
If PMI is not be enabled, some PMI data can't be collected, such as the Object Pool data.
Viewing metrics
To view the metrics, complete the following steps:
- In the sidebar of the Instana UI, select Infrastructure.
- Click a specific monitored host.
Then, you can see a host dashboard with all the collected metrics and monitored processes.

Health signatures
Each sensor has a curated knowledgebase of health signatures that are evaluated continuously against the incoming metrics and are used to raise issues or incidents depending on user impact.
Built-in events trigger issues or incidents based on failing health signatures on entities, and custom events trigger issues or incidents based on the thresholds of an individual metric of any given entity.
For information about built-events for the WebSphere Application Server sensor, see the Built-in events reference.
Viewing JMS metrics
The Java Message Service (JMS) metrics are collected from Tracing. These metrics are shown on the "Analytics" dashboard with the filtering Call > Type = MESSAGING AND Dest > Endpoint > Name = <Your destination>:
For more information, see Unbounded analytics.
