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.

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 (~)
hostMetadataConditionsThe 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.

HostMetadataCondition objectkeyMustExistWhen enabled, the condition requires a metadata key to exist and match the constraints; when disabled, the key is optional but must still match the constrains if it is present.

$not($eq(production)) – Matches if the host metadata value is different from production.$and($prefix(production),$suffix(main)) – Matches if host metadata value starts with production and ends with main.$or($prefix(production),$suffix(main)) – Matches if host metadata value starts with production or ends with main.Brackets ( and ) that are part of the matched property must be escaped with a tilde (~)
