My mongodb server running on local (127.0.0.1:27017). I have 2 user in mongodb database. 1 for application and 2nd user with read only permission. (Eg. user/password). I configure the 2nd user in mondodb.yml module, which present in "module.d" folder . But when i start my metric beat, it throw this error for mongodb.

ERROR ->

Hello, I see in mongodb.yml, you have metricsets commented. Please try your config with the second line #metricsets uncommented:

- module: mongodb
  metricsets:
    - dbstats
    - status
    - collstats
    - metrics
    - replstatus
  period: 10s
  hosts: ["localhost:27017"]
  username: securaauser
  password: password

Sorry for the late response, I think the new error is caused by some settings in MongoDB for permissions. I have a PR open for fixing the original error message: https://github.com/elastic/beats/pull/14143
