For more\ninformation, see [Metrics](/network-intelligence-center/docs/performance-dashboard/concepts/overview#metrics).\n\nEvents affecting Performance Dashboard metrics might take up to 10\nminutes to appear.\n\nView project-specific latency data for traffic between zones\n------------------------------------------------------------\n\nThe latency graph shows the median latency across all project zones over\ntime. The vertical axis shows the median latency in milliseconds (ms), and the\nhorizontal axis shows the change over time.\n\n#### Permissions required for this task\n\nTo perform this task, you must have been granted the following permissions\n*or* the following IAM roles.\n\n**Permissions**\n\n- `monitoring.timeSeries.list`\n\n**Roles**\n\n- Monitoring Viewer (`roles/monitoring.viewer`)\n- Monitoring Editor (`roles/monitoring.editor`)\n- Monitoring Admin (`roles/monitoring.admin`)\n\n\u003cbr /\u003e\n\n### Console\n\n1. In the Google Cloud console, go to the **Performance Dashboard** page.\n\n [Go to Performance Dashboard](https://console.cloud.google.com/net-intelligence/performance/dashboard)\n2. Click **Per Project**.\n3. In the **View options** panel, in the **Traffic type** section, select\n **Cross-zonal** to view latency data between VMs.\n\n To view the latency data between VMs and internet endpoints, see\n [View latency information for **Internet to Google Cloud** traffic type](#latency-internet).\n4. In the **Metric** section, select **Latency (RTT)**.\n\n5. In the **Time period** section, choose the view interval from **1 hour**\n to **6 weeks**.\n\n6. In the **Google Cloud regions** section, select the regions for which you\n want to view data. You can select up to five regions.\n\n7. On the horizontal axis, click a time to show a heatmap of **median latency\n between zone pairs** at that time. Slide the time selector to show latency\n at different times.\n\n8. In the latency view between zones heatmap, click a particular square.\n In the **Latency details for your project** page that appears, you can view\n the bidirectional latency graph between those two zones and a table that shows\n the latency between the VMs and zones.\n The latency table lists the VMs, their projects, and the corresponding\n latency details.\n\n9. To narrow your results for the VMs and view their latency details, use a\n property to create an advanced filter query.\n\n10. To view the latency details of the VM on the monitoring page, click\n **View Monitoring**.\n\nThe latency heatmap only shows zone pairs with enough traffic to provide latency\ninformation.\n\nIn Shared VPC service projects, individual service projects\ndon't have access to the latency metrics of the host project.\n\nSimilarly, in peered VPC networks that sit in different\nprojects, the individual projects don't have access to the latency metrics for\ntraffic moving between the networks.\n\nFor more details, see [Latency](/network-intelligence-center/docs/performance-dashboard/concepts/overview#latency).\n\nView project-specific latency data for traffic between Google Cloud regions and internet endpoints\n--------------------------------------------------------------------------------------------------\n\nThe project-specific latency views show the median round-trip time (RTT) between selected\ngeographic areas and regions that contain VM instances in your project. The latency\nsummary is available in three views: **Table** view, **Map** view, and\n**Timeline** view. Select the specific locations or regions to view the latency\ngraph.\n\nThe latency graph shows the median latency between Google Cloud regions\nand internet endpoints. The vertical axis shows the median latency in\nmilliseconds (ms), and the horizontal axis shows the change over time.\n\nTo view project-specific latency data between Google Cloud and the internet,\ncomplete the following steps.\n\n#### Permissions required for this task\n\nTo perform this task, you must have been granted the following permissions\n*or* the following IAM roles.\n\n**Permissions**\n\n- `monitoring.timeSeries.list`\n\n**Roles**\n\n- Monitoring Viewer (`roles/monitoring.viewer`)\n- Monitoring Editor (`roles/monitoring.editor`)\n- Monitoring Admin (`roles/monitoring.admin`)\n\n\u003cbr /\u003e\n\n### Console\n\n1. In the Google Cloud console, go to the **Performance Dashboard** page.\n\n [Go to Performance Dashboard](https://console.cloud.google.com/net-intelligence/performance/dashboard)\n2. Click **Per Project**.\n3. In the **View options** panel, in the **Traffic type** section, select\n **To the internet** to view latency data between VMs and internet endpoints.\n\n4. In the **Metric** section, select **Latency (RTT)**.\n\n5. In the **Time period** section, choose the view interval from **1 hour**\n to **6 weeks**.\n\n6. In the **Google Cloud regions** section, select the regions for which you\n want to view data. You can select up to five regions.\n\n7. In the **Network tier** section, select **Show data only for the selected\n tier**.\n\n8. In the **Network tier** menu, select **Standard** or **Premium** .\n For more information about tiers, see the\n [Network Service Tiers overview](/network-tiers/docs/overview).\n\n9. To view the latency summary, select one of these three views:\n\n - **Table** view\n - **Map** view\n - **Timeline** view\n10. In the **Table** view, do the following:\n\n 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.\n 2. To view the latency details on the graph, select the specific country to region path.\n 3. To view the latency details for a specific time, point to the traffic path on the graph.\n11. In the **Map** view, do the following:\n\n 1. To view the latency details of a specific location, point to the geographic location on the map.\n 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.\n 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.\n 4. To view the latency details of a specific traffic path, select the traffic path from the list of available traffic paths.\n12. In the **Timeline** view, do the following:\n\n 1. To select a specific country, in the **Filter** field, use the **Country** property.\n 2. In the Latency table, click **View** to view the latency between the VMs in the selected locations and internet endpoints.\n 3. Refine the graph further by using the properties in the **Filter** field.\n\n The latency graph shows the latency details for the selected time interval\n along with aggregate latency values in the legend that follows the graph.\n\nWhat's next\n-----------\n\n- [View project-specific packet loss dashboard](/network-intelligence-center/docs/performance-dashboard/how-to/view-project-specific-packet-loss)\n- [View Google Cloud packet loss dashboard](/network-intelligence-center/docs/performance-dashboard/how-to/view-google-cloud-packet-loss)\n- [View Google Cloud latency dashboard](/network-intelligence-center/docs/performance-dashboard/how-to/view-google-cloud-latency)\n- [Performance Dashboard metrics reference](/network-intelligence-center/docs/performance-dashboard/how-to/viewing-perf-dash-metrics)\n- [Troubleshoot Performance Dashboard](/network-intelligence-center/docs/performance-dashboard/support/troubleshooting)"]]
