The vertical axis shows\nthe percentage of packet loss, and the horizontal axis shows when the losses\noccurred for the chosen regions.\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/global-dashboard)\n2. Click **Google Cloud**.\n3. In the **View options** panel, in the **Traffic type** section, select **Cross-zonal**.\n4. In the **Metric** section, select **Packet loss**.\n5. In the **Time period** section, choose the view interval from **1 hour** to **6 weeks**.\n6. In the **Google Cloud regions** section, select the regions for which you want to view data. You can select up to five regions.\n7. On the horizontal axis, click a time to show a heatmap of **average packet\n loss between zone pairs** at that time. Slide the time selector to show packet loss at different times.\n8. In the heatmap, click a particular square to see a bidirectional graph of packet loss between those two zones.\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 project-specific latency dashboard](/network-intelligence-center/docs/performance-dashboard/how-to/view-project-specific-latency)\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)"]]
