PMM2 new install, mongodb stats/queries not showing

Hello all, I just installed pmm2 and pointed it at a server that runs postgres and mongo.  The postgres queries/stats showed in the dashboards, but Im not seeing any data for the mongo DB.

I did the following:
Enabled profiling in the mongod.conf

mode: slowOp
slowOpThresholdMs: 200
slowOpSampleRate: 100

I created the mongodb_exporter user in mongo via:

user: "mongodb_exporter",
pwd: "somesecret",
roles: [
{ role: "clusterMonitor", db: "admin" },
{ role: "readAnyDatabase", db: "admin" }

I restarted mongo, and then I ran the following command: 

pmm-admin add mongodb --username=mongodb_exporter --password=somesecret --service-name=mongo --host= --port 27017  --query-source=profiler --cluster=qa_host1
And I can see the above service running, both via pmm-admin list, and in the pmm2 dashboard under inventory.
Im at a loss as to how to troubleshoot further, it appears pmm2 doesn’t log much or expose log files that I’ve found.

Any suggestions or ideas would be greatly appreciated.
Thank you,

@tman77  , the first place to check is to make sure you have some queries executed longer than 200ms, or  lower threshold for initial testing
