When sharing a Cloud chart to monitor CPU utilization with your SRE team, what is the best option to ensure minimal access?

The best option for ensuring minimal access while sharing a Cloud chart to monitor CPU utilization with the SRE team is to click "Share chart by URL" and provide the SRE team with the URL along with the Monitoring Viewer IAM role. This method allows for the specific sharing of the chart without granting additional permissions that could come with sharing the entire project or dashboard.

By sharing just the URL, the team members can view the specific chart without needing broader access that a project ID or dashboard viewer role would inherently provide. The Monitoring Viewer IAM role is specifically designed to enable viewing monitoring data, ensuring that team members can see the relevant metrics without being able to make changes or access other resources within the project. Thus, this approach balances the need for visibility into CPU utilization while maintaining a level of security by restricting their broader access to the project.

Sharing the URL is a direct method of providing access to the specific chart, thereby preventing potential misuse or unwanted changes while still allowing the SRE team to gather the required performance data.
