Sharing Cloud Monitoring Dashboards with External Partners

The question asks how to share a Cloud Monitoring custom dashboard with a partner team. The key constraint is that the partner team likely resides in a different Google Cloud project or organization, meaning direct IAM-based sharing of the dashboard resource is not feasible or desirable due to security boundaries.

Option A suggests providing the dashboard URL so the partner can create a copy. However, the official Google Cloud documentation explicitly states: "We recommend that you use Monitoring to send the URL of a dashboard to your recipients when you have that option... Monitoring identifies those recipients who might not have permission to view the dashboard and provides an option for you to grant the required permissions." This implies that URL sharing relies on the recipient having access to the source project's resources (or granting them access), which is often not the case for external partners. More importantly, the comment thread highlights that simply sending a URL does not allow the partner to create a copy in their own project without first gaining access to the source project, which violates the principle of least privilege. The 'copy' functionality within the UI typically requires viewing access to the original dashboard.

Option D suggests downloading the JSON definition and sending it. While this allows the partner to import the dashboard structure into their own project, it is a manual process and does not constitute 'sharing' in the active sense. It is a method of duplication, not sharing. However, many community members argue for D because it allows the partner to recreate the dashboard in their own environment without needing access to yours. But let's look at the wording again: "What should you do?"

Let's re-evaluate based on standard GCP exam logic. If the goal is to share the view of the data, you need access. If the goal is to share the configuration so they can monitor their own similar resources, you export/import. The question says "share a... dashboard". Usually, this implies making it visible or accessible. But wait, if the partner is external, they cannot see your dashboards via URL unless you grant them IAM roles on your project, which is bad practice. Therefore, the only secure way to give them the exact same dashboard layout/queries for their own use is to export the JSON (D) and have them import it.

However, there is a nuance. The official doc says "send the URL... when you have that option". This usually applies to internal teams. For external partners, JSON export/import is the standard mechanism for portability. Let's look at the votes. Votes are split between A and D. Comments favor D for portability and security (no cross-project IAM). Comments favor A for simplicity but admit it requires permissions.

Actually, looking closer at Option A: "Provide the partner team with the dashboard URL to enable the partner team to create a copy of the dashboard." The ability to 'Copy' a dashboard in GCP Monitoring is available to users with roles/viewer or higher on the dashboard. If you just send a URL, they can't copy it unless they have access. So A is technically incorrect as a standalone action without preceding IAM changes.

Option D: "Download the JSON definition... and send the JSON file." This is the correct method for transferring dashboard configurations across projects/organizations where IAM sharing is not possible. The partner imports the JSON to create their own dashboard. This is the robust, secure answer for 'partner teams'.

Therefore, D is the most technically accurate answer for sharing with an external entity.
