Glowroot page broken using a custom portal context

Issue

• If we define a context other than ROOT in our portal, for example myportal, the Glowroot administration pages are not displayed or are displayed with visual errors.

Environment

• Liferay DXP 2023.Q4

Resolution

• Currently, to use Glowroot with a custom context other than ROOT, it is necessary to apply these settings:

  • Edit $LIFERAY_HOME/glowroot/admin.json and specify the contextPath:
    

    ...
    "web": {
        "port": 4000,
        "bindAddress": "127.0.0.1",
        "contextPath": "/myportal/o/glowroot",
        "sessionTimeoutMinutes": 30,
        "sessionCookieName": "GLOWROOT_SESSION_ID"
    },
    ...

  • Inside $LIFERAY_HOME/osgi/configs, it is necessary to add the configuration file com.liferay.glowroot.proxy.internal.servlet.GlowrootProxyServlet.config indicating the contextPath (it will be necessary to restart the server for the configuration to take effect), as an example:

    servlet.init.targetUri="http://localhost:4000/myportal/o/glowroot"

Additional Information

• Change root context to custom context.
• Using Glowroot with Liferay.
