Using Performance Dashboard

Performance Dashboard metrics are automatically collected for your project. The Google Cloud performance view presents the overall Google Cloud metrics for each possible Google Cloud zone pair. You do not have to do any setup, but you do need a certain number of VMs in your project to get good results. For more information, see Metrics.

Events affecting Performance Dashboard metrics might take up to 10 minutes to appear.

To view project metrics, click View project performance at the top of the Performance Dashboard page. To view global metrics, click View performance for all of Google Cloud.

Viewing packet loss information

The packet loss graph shows packet loss over time. The vertical axis shows the percentage of packet loss, and the horizontal axis shows when the losses occurred.

Console

  1. In the Google Cloud Console, go to the Packet loss page.

    Go to Packet loss

  2. Choose a view interval by using the buttons across the top of the graph, from 1 hour to 6 weeks.
  3. On the horizontal axis, click a time to show a heatmap of average packet loss between zone pairs at that time. Slide the time selector to show packet loss at different times.
  4. In the heatmap, click a particular square to see a bidirectional graph of packet loss between those two zones.

In the case of Shared VPC service projects, individual service projects might not be able to see all the information. For example, suppose one service project has VMs in one zone only and another service project has VMs in a different zone only. If the two sets of VMs are exchanging traffic, each service project only sees packet loss for the traffic heading toward their VMs.

Similarly, in the case of peered Virtual Private Cloud (VPC) networks that sit in different projects, each project sees packet loss only for traffic heading toward their VMs.

To learn how you can view information from more than one project, see Network performance for multiple projects.

Viewing packet loss information in the Google Cloud performance view

The packet loss graph shows packet loss over time. The vertical axis shows the percentage of packet loss, and the horizontal axis shows when the losses occurred for the chosen regions.

Console

  1. In the Google Cloud Console, go to the Packet loss page.

    Go to Packet loss

  2. From the Locations drop-down, select the regions for which you want to view data. You can select up to five regions. By default, if you do not select the regions, the information is shown for all regions.
  3. Choose a view interval by using the buttons across the top of the graph, from 1 hour to 6 weeks.
  4. On the horizontal axis, click a time to show a heatmap of average packet loss between zone pairs at that time. Slide the time selector to show packet loss at different times.
  5. In the heatmap, click a particular square to see a bidirectional graph of packet loss between those two zones.

Viewing latency information

The latency graph shows the median latency across all project zones over time. The vertical axis shows the median latency in milliseconds (ms), and the horizontal axis shows the change over time.

Console

  1. In the Google Cloud Console, go to the Latency page.

    Go to Latency

  2. Choose a view interval by using the buttons across the top of the graph, from 1 hour to 6 weeks.
  3. On the horizontal axis, click a time to show a heatmap of median latency between zone pairs at that time. Slide the time selector to show latency at different times.
  4. In the heatmap, click a particular square to see a bidirectional graph of latency between those two zones.

The latency heatmap only shows zone pairs with enough traffic to provide latency information.

In the case of Shared VPC service projects, individual service projects do not see latency metrics for the host project.

Similarly, in the case of peered VPC networks that sit in different projects, the individual projects do not see latency for traffic moving between the networks.

For more details, see Latency.
