I checked with CA Wily support and was told that the Wily Java agents currently do not have support for MongoDB. I would like to add this MongoDB support as an enhancement request.
There is a MongoDB pbd here on the community: CA APM Mongo PBD file
We dont have support for Mongodb in the java agents but We released a mongodb fieldpack last year, more details can be found here
CA APM MongoDB Collector Fieldpack
Additionally, we are continuously enhancing our java agents to automatically discover application components and instrument all the critical activity inside the agent.
