MongoDB without SSL

[gallart]

Bug report

Mongodb telegraf input seems to require SSL. Could not find any documentation on how to disable SSL.

Relevant telegraf.conf:

# MONGO
[[inputs.mongodb]]
  servers = ["mongodb://login:password@127.0.0.1:27017"]
  gather_perdb_stats = false

System info:

• Gentoo Linux
• Telegraf 1.1.2
• Mongo 2.6.12

Steps to reproduce:

1. ./telegraf -config telegraf.conf -test -input-filter mongodb

Expected behavior:

Result of mongodb stats.

Actual behavior:

error dialing over ssl, server returned error on SASL authentication step: Authentication failed.
2016/12/29 14:40:22 Errors encountered: [Unable to connect to MongoDB, server returned error on SASL authentication step: Authentication failed.

Thanks,

Gaëtan

your connection is failing because the user/password is wrong, it is not actually using SSL, the log message is simply wrong.

Fix for this is to delete the fmt.Printf here: https://github.com/influxdata/telegraf/blob/master/plugins/inputs/mongodb/mongodb.go#L131-L133
