Activity Monitor Database Type incorrectly displayed?

Rising Star

Cloudera Manager Express 5.2

 

CM was installed in Path A with all default options. In Configration tab (CM main Page -> Cloudear Management Service -> Configuration), "Activity Monitor Database Type" was displayed as mysql. The information point to non-existent mysql database. 

Actually I think we don't have mysql across the CDH cluster.


Since we use Path A, I believe we are actually using internal PostgreSQL DB for all CM databases. We can login "amon" PostgreSQL database according to info in /etc/cloudera-scm-server/db.mgmt.properties. 

 

Is CM displaying wrong information? How can I confirm which database amon is using (or none)?

 

Thanks.
