This extension documentation is now deprecated and will no longer be updated. We recommend using the new WSO2 API Manager extension for improved functionality and support.
WSO2 API Manager is a fully open-source, full lifecycle API Management solution.
Go to Hosts or Hosts Classic, find your WSO2 host, select it to open Host overview page, and select the Tomcat process responsible for running WSOA2 API Manager.
You'll find all the collected metrics in the WSO2 API Manager process group page.
