Error establishing direct connection to mongo node Error output: no reachable servers

Hi,

Here is the log:

 Error establishing direct connection to mongo node at [127.0.0.1:27017]. Error output: no reachable servers

I tried a lot of things, but after so many days, I can't find it work.

Here is my mongodb.yml configuration


# Module: mongodb
# Docs: https://www.elastic.co/guide/en/beats/metricbeat/7.10/metricbeat-module-mongodb.html

- module: mongodb
  metricsets:
    - dbstats
   # - status
   # - collstats
   # - metrics
   # - replstatus
  period: 10s

  # The hosts must be passed as MongoDB URLs in the format:
  # [mongodb://][user:pass@]host[:port].
  # The username and password can also be set using the respective configuration
  # options. The credentials in the URL take precedence over the username and
  # password configuration options.
  hosts:
   - "mongodb://127.0.0.1:27017"

It doesn't have a password. I verified it by running on local and also remote.

The /etc/mongod.conf bind IP is set to 0.0.0.0. I verified that it can connect outside using this command.

mongosh mongodb://18.191.206.XXX:27017

I am using MongoDB version 4, I tried using MongoDB version6 but it doesn't work as well.

My Metricbeat Version is OSS 7.2

Here is the fulll error log:

Elasticsearch version 7.10 is EOL and no longer supported. Please upgrade ASAP.

is metricbeat running on the same host? The error message indicates nothing is running.
Does providing the remote other IP address work?

Yes the metricbeat is running on the same host.

The mongodb is also running on the same host.

Providing the more IP address doesn't work.

Accessing the mongodb locally and remotely does work, I tried testing it via mongosh.

Are you able to run mongosh on the localhost also?

Also, Is it possible for you to upgrade the stack and see if this issue is only for older version.

Hi I've tried using a new instance and set up mongodb version 4.2, it does work now.
