View project-specific latency dashboard

Performance Dashboard metrics are automatically collected for your project for the following traffic types:

  • Latency metrics for each possible Google Cloud zone pair
  • Latency metrics between regions where you have virtual machine (VM) instances and the internet locations that communicate with the VMs

You do not have to do any setup, but you do need a certain number of VMs in your project to get the details in the project performance dashboard. For more information, see Metrics.

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

View project-specific latency data for traffic between zones

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 Performance Dashboard page.

    Go to Performance Dashboard

  2. Click Per Project.

  3. In the View options panel, in the Traffic type section, select Cross-zonal to view latency data between VMs.

    To view the latency data between VMs and internet endpoints, see View latency information for Internet to Google Cloud traffic type.

  4. In the Metric section, select Latency (RTT).

  5. In the Time period section, choose the view interval from 1 hour to 6 weeks.

  6. In the Google Cloud regions section, select the regions for which you want to view data. You can select up to five regions.

  7. 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.

  8. In the latency view between zones heatmap, click a particular square. In the Latency details for your project page that appears, you can view the bidirectional latency graph between those two zones and a table that shows the latency between the VMs and zones. The latency table lists the VMs, their projects, and the corresponding latency details.

  9. To narrow your results for the VMs and view their latency details, use a property to create an advanced filter query.

  10. To view the latency details of the VM on the monitoring page, click View Monitoring.

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

In Shared VPC service projects, individual service projects don't have access to the latency metrics of the host project.

Similarly, in peered VPC networks that sit in different projects, the individual projects don't have access to the latency metrics for traffic moving between the networks.

For more details, see Latency.

View project-specific latency data for traffic between Google Cloud regions and internet endpoints

The project-specific latency views show the median round-trip time (RTT) between selected geographic areas and regions that contain VM instances in your project. The latency summary is available in three views: Table view, Map view, and Timeline view. Select the specific locations or regions to view the latency graph.

The latency graph shows the median latency between Google Cloud regions and internet endpoints. The vertical axis shows the median latency in milliseconds (ms), and the horizontal axis shows the change over time.

To view project-specific latency data between Google Cloud and the internet, complete the following steps.

Console

  1. In the Google Cloud console, go to the Performance Dashboard page.

    Go to Performance Dashboard

  2. Click Per Project.

  3. In the View options panel, in the Traffic type section, select To the internet to view latency data between VMs and internet endpoints.

  4. In the Metric section, select Latency (RTT).

  5. In the Time period section, choose the view interval from 1 hour to 6 weeks.

  6. In the Google Cloud regions section, select the regions for which you want to view data. You can select up to five regions.

  7. In the Network tier section, select Show data only for the selected tier.

  8. In the Network tier menu, select Standard or Premium. For more information about tiers, see the Network Service Tiers overview.

  9. To view the latency summary, select one of these three views:

    • Table view
    • Map view
    • Timeline view

  10. In the Table view, do the following:

    1. To view the latency metrics from a country to the regions that contain VM instances in your project, click View. The country-specific details appear in a sidebar that shows the traffic from the selected country to the regions that contain VM instances in your project.
    2. To view the latency details on the graph, select the specific country to region path.
    3. To view the latency details for a specific time, point to the traffic path on the graph.

  11. In the Map view, do the following:

    1. To view the latency details of a specific location, point to the geographic location on the map.
    2. To view the median latency between a Google Cloud region and geographic locations, click the Google Cloud region. The map refreshes to display the locations with traffic with the selected region.
    3. To view the latency details over a time period, click a geographic location. The location-specific details appear in a sidebar that shows the traffic from the selected location to the regions that contain VM instances in your project.
    4. To view the latency details of a specific traffic path, select the traffic path from the list of available traffic paths.

  12. In the Timeline view, do the following:

    1. To select a specific country, in the Filter field, use the Country property.
    2. In the Latency table, click View to view the latency between the VMs in the selected locations and internet endpoints.
    3. Refine the graph further by using the properties in the Filter field.

    The latency graph shows the latency details for the selected time interval along with aggregate latency values in the legend that follows the graph.
