WebSphere Applications agent: Unconfiguring the data collector
If you uninstall the WebSphere Applications agent before you unconfigure the data collector, the agent uninstallation fails. You can remove the data collector from an application server instance manually or by using the interactive utility or the silent unconfiguration process.
For instances that are monitored with PMI resource monitoring, unconfiguration is not available. Monitoring of PMI data continues while the server is available.
