When I attempt to access the URL: https://<hostname>:<port>/nifi-api/system-diagnostics/jmx-metrics I received a 404 Not Found error, stating that the requested resource could not be found. I have also ensured that I included the necessary authentication in the request headers. Additional Details: I have tried accessing the JMX metrics both locally and in production environments, but the issue persists in both cases. In the nifi.properties file under the web properties section, I added the following property to enable JMX metrics: nifi.web.jmx.metrics.allowed.filter.pattern=.* I would appreciate any guidance or suggestions on resolving this issue. Thank you for your assistance! Best regards, Soundarya Parthiban mailto:soundary...@funbook.org.in
