I added this in our shared slack channel but sharing here as well:

It would be great if you could also highlight these new metrics in the dashboard that’s included with the integration. The best way to update it is to:

1. Copy the json from here into your sandbox in a new dashboard https://github.com/DataDog/integrations-extras/tree/master/mongodb_atlas/assets/dashboards
2. Make the necessary changes and add new widgets
3. Export it as JSON
4. Replace the file from step 1 and add it to your pull request

Integration Dashboards are typically where customers start when it comes to monitoring another technology and so we want to make sure it’s as comprehensive as possible. Otherwise metrics just get buried within a Datadog customer’s org.

Hi @Salil999 Could I also ask you to update the author within the manifest.json to MongoDB as well as the codeowners file? We'd like to acknowledge that this integration is built and maintained by Datadog.

Hi @eho1307, just to clarify, should the author be a mongodb contact or a datadog contact? thanks!

Within the manifest.json, you can update the author fields to contacts at MongoDB, for example:

"author": {
"support_email":
"name": "MongoDB",
"homepage": https://www.mongodb.com/
"sales_email":

The support email and sales email should be MongoDB email addresses.
