You can access the host map from the Infrastructure link in the navigation bar in your Datadog account. The host map represents each host as a hexagon, with colors showing the percentage of CPU utilization on the host. You can easily change the host map to represent different metrics and choose a different color palette. The size of each hexagon represents the relative value of a metric, such as uptime or disk free space. You can filter and group your hosts using tags, allowing you to visualize a subset of your infrastructure based on shared attributes. Once you've filtered and visualized your host data, you can easily save the host map to use again later.
