Settings API - Anomaly detection for infrastructure- Disk Edge schema table

Anomaly detection for infrastructure: Disk Edge (`builtin:infrastructure.disk.edge.anomaly-detectors)`

The Disk Edge feature within Dynatrace provides automatic detection of performance anomalies related to disk infrastructure. Use these settings to tailor detection sensitivity to a specific disk's name and/or custom metadata. Defining custom properties can help with post processing of the event.

Policy Hierarchy and Scope

The order of policies establishes a hierarchical structure. Disk is assigned to the first policy it matches to (based on disk name and/or metadata) according to the policies hierarchy.

Policies can be defined within Host, Host Group and Tenant scope. Lower scope has priority over the higher one.

To learn more about Disk Edge visit its official documentation.

Parameters

Property	Type	Description	Required
Policy name `policyName`	text	-	required
Enabled `enabled`	boolean	-	required
Operating system `operatingSystem`	Set<EOperatingSystem>	Select the operating systems on which policy should be applied `WINDOWS` `LINUX` `AIX`	required
Alerts `alerts`	Set<Alert>	-	required
Disk name filters `diskNameFilters`	set	Disk will be included in this policy if any of the filters match Disk name filter has to match a required format. `$match(/zSecure/snapshot?/)` – Matches string with wildcards: `` any number (including zero) of characters and `?` exactly one character. `$contains(/log/)` – Matches if `/log/` appears anywhere in disk name. `$eq(/)` – Matches if `/` matches the disk name exactly. `$prefix(/srv/)` – Matches if `/srv/` matches the prefix of disk name. `$suffix(/backup)` – Matches if `/backup` matches the suffix of disk name. Available logic operations: `$not($eq(/usr))` – Matches if the disk name is different from `/usr`. `$and($prefix(/var),$suffix(/backup))` – Matches if disk name starts with `/var` and ends with `/backup`. `$or($prefix(/home/),$eq(/root))` – Matches if disk name starts with `/home` or equals `/root`. Brackets ( and ) that are part of the matched disk name must be escaped with a tilde (~)	required
Host custom metadata conditions `hostMetadataConditions`	Set<HostMetadataConditionType>	The policy will be enabled if all conditions are met Host custom metadata refers to user-defined key-value pairs that you can assign to hosts monitored by Dynatrace. By defining custom metadata, you can enrich the monitoring data with context specific to your organization's needs, such as environment names, team ownership, application versions, or any other relevant details. See Define tags and metadata for hosts.	required
Properties `eventProperties`	Set<MetadataItem>	Set of additional key-value properties to be attached to the triggered event. You can retrieve the available property keys using the Events API v2.	required
