The Tag Coverage Explorer shows how much of your estate is tagged, broken down by the patterns in your device names. Most organisations name devices by site, type or team, so grouping by name prefix shows quickly which groups of devices your tags are missing. You can then create a tag for a prefix without leaving the page. To open it, go to Settings → Tags and click Coverage Explorer. Tag Coverage Explorer showing a treemap of device-name prefixes (B.., A.., NA.., E.., D.. and others) sized by device count, with a card reading 1,158 devices in the IT estate, 92.9% of these devices have one or more tags, and the tags BYOD, Mac, VM, Server, End-User, NA, EMEA, APAC and Stock

​
Reading the treemap

Each block is a group of devices whose names start with the same characters, such as B.. or NA.., sized by how many devices it contains. Coloured areas are devices with at least one tag; grey areas are devices with no tags. A block with a large grey area is a group your tag rules don’t reach. The card on the right summarises whatever you’re looking at: Hover over a block to see its card alongside the estate total.

​
Drilling into a prefix

Click a block to zoom into it. The treemap splits that group by the next character of the name, for example from D.. into DE.., so you can find exactly where the untagged devices are. Use the Home and Up buttons on the left of the treemap to go back.

​
Tagging a prefix

When you find a group that should have its own tag, select it and click + Tagging Rule on its card.
1

Add the rule

The rule appears under New Dynamic Rules at the bottom right, as Starts with the prefix. The card shows what coverage would be with the new tag.
2

Name the tag

Give the tag a name, and change its colour if you like. You can add rules for several prefixes before saving, and remove one with ×.
3

Save

Click Save and Apply Dynamic Rules. The rules stay unsaved until you do.

​
Changing what’s shown

Click the Active Devices — All Tags menu next to the title to change the view. Changes apply when you close the menu.
  • Show only active devices: on by default. Turn it off to include inactive devices.
  • Show only name based dynamic tags: only count tags whose rule is based on a device-name prefix, to see how far your naming convention alone gets you.

​
When to use it

  • After you change a tag rule, to check your coverage didn’t drop.
  • When you first set up tags, to find the naming patterns worth tagging.
  • From time to time, because new devices with unfamiliar names often arrive untagged.
Devices with no tags have no Vitals requirements, so gaps here are usually the first thing to fix. If some devices are out of scope on purpose, such as new stock, give them a tag like Stock so they’re counted as covered. See Tags.
