+### Resource tag filtering
+
+Use tag filters to control which Azure resources have their metrics collected by Datadog. A tag filter is a comma-separated list of tags in the form `key:value`. Only resources that match at least one tag in the filter have their metrics collected.
+
+You can use wildcards in your tag filters:
+- `?` matches a single character.
+- `*` matches multiple characters.
+
+To exclude resources with a given tag, prefix the tag with `!`. Exclusion takes precedence over inclusion. A resource matches the filter if it matches any tag in the list.
+
+For example: `datadog:monitored,env:production,!plan_tier:basic,instance-type:c1.*`
+
+This filter collects metrics from resources tagged with `datadog:monitored` or `env:production`, excludes resources tagged with `plan_tier:basic`, and includes resources with an `instance-type` tag matching `c1.*`.

 ## Enable log collection
 
 You can use the automated log forwarding feature to setup and configure the services and diagnostic settings needed to forward logs to Datadog. If an automated log forwarding control plane already exists in the tenant, this flow modifies it and extends its scope to include the selected subscriptions or management groups. For more detail, see [Azure Automated Log Forwarding Setup][19].
