Thank you for posting your query!

Can you please try installing the integration using manual method

First install the agent on your OS then, manually install the integration.

Also, Can you please tell your OS details.

@yverma1 thanks for the reply. I am using ubuntu (version 20). I am also gone through the manual steps. Manual steps are not clear. I am not sure how can i check if manual steps are correct. if you can provide manual steps with explicit steps , i think that will be great for me. thanks

Hello @questt.devops ,

Remember to install the agent through guided install HERE.

  1. Follow the instructions for installing an integration, using the file name nri-mongodb.

  2. Change directory to the integrations folder:

cd /etc/newrelic-infra/integrations.d
  1. Copy of the sample configuration file:
sudo cp mongodb-config.yml.sample mongodb-config.yml
  1. Edit the mongodb-config.yml file as described in the configuration settings.
  2. Restart the infrastructure agent.
  3. To enable automatic MongoDB error log parsing and forwarding, copy (or rename) the mongodb-log.yml.example file to mongodb-log.yml. No need to restart the agent.Example: 
sudo cp /etc/newrelic-infra/logging.d/mongodb-log.yml.example /etc/newrelic-infra/logging.d/mongodb-log.yml

Thanks for specifying the steps. I have tried but not working. I am sharing mongo-config.yml file with you. Please let me know what I am missing and for restart I am using sudo systemctl status newrelic-infra and I am not sure how to check if mongodb configuration is working correctly or get more info through logs so that i can debug accordingly.
Thanks

    The mongos to connect to

    HOST: localhost

    The port the mongos is running on

    PORT: “27017”

    The username of the user created to monitor the cluster.

    This user should exist on the cluster as a whole as well

    as on each of the individual mongods.

Hello @questt.devops ,

Thank you for your patience! Can you create a case in Newrelic support portal .

Aslo , Please try these steps :slight_smile:

As the error represents we are not able to create a connection

  1. Please Check compatibility and requiremt.

2.Create roles and user for newrelic to access the cluster.

3.Try to connect to mongo db instance through that user and password.

  1. Then try to run the command given on previous reply and see if you are able to create a session,

  2. Also I am attaching the sample yaml file , Note : for atlas there is another config.yml .

please follow this !

Hello @questt.devops ,

Yeah , it seems to be working manually . So it will work via integartion as well .

Can you please update the details in the mongodb-config.yml , as you have mentioned it here in the command. and restart the infra agent .

You can see the data in infrastructure>third party services > Mongo DB.

If it doesn’t work can you please get the verbose logs
