Charts: [bitnami/mongodb] when auth disabled, mongod throws an error about its exporter connection

when auth disabled, mongod throws errors as follows, with and without root user password:

2020-06-30T18:40:40.152+0000 I  ACCESS   [conn560] Supported SASL mechanisms requested for unknown user 'root@admin'
2020-06-30T18:40:40.152+0000 I  ACCESS   [conn560] SASL SCRAM-SHA-1 authentication failed for root on admin from client 127.0.0.1:38408 ; UserNotFound: Could not find user "root" for db "admin"
2020-06-30T18:40:40.153+0000 I  NETWORK  [conn560] end connection 127.0.0.1:38408 (17 connections now open)

I guess the exporter should connect without _root@_ when auth is disabled...?

Hi @ianhlee ,
Thank you very much for reporting the issue. I am not totally sure I understand the issue, could you share the steps to reproduce it?

[ReToCode]

I have the same issue. Just deploy the chart with auth.enabled: false and metrics.enabled: true. The connection from the metrics container will fail with:

mongodb container

metrics container
