Examples

Set a policy with multiple workload groups

Set a policy which, based on the evaluation of multiple conditions, assigns the user to one among many different workload groups or to default:

.alter cluster policy request_classification '{"IsEnabled":true}' <|
    case(current_principal_is_member_of('aadgroup=somesecuritygroup@contoso.com'), "First workload group",
         request_properties.current_database == "MyDatabase" and request_properties.current_principal has 'aadapp=', "Second workload group",
         request_properties.current_application == "Kusto.Explorer" and request_properties.request_type == "Query", "Third workload group",
         request_properties.current_application == "KustoQueryRunner", "Fourth workload group",
         request_properties.request_description == "this is a test", "Fifth workload group",
         hourofday(now()) between (17 .. 23), "Sixth workload group",
         "default")

Output

PolicyName EntityName Policy ChildEntities EntityType
ClusterRequestClassificationPolicy {"ClassificationProperties": ["current_database", "request_description", "current_application", "current_principal", "request_type"], "IsEnabled": true, "ClassificationFunction": "case(current_principal_is_member_of('aadgroup=somesecuritygroup@contoso.com'), "First workload group", request_properties.current_database == "MyDatabase" and request_properties.current_principal has 'aadapp=', "Second workload group", request_properties.current_application == "Kusto.Explorer" and request_properties.request_type == "Query", "Third workload group", request_properties.current_application == "KustoQueryRunner", "Fourth workload group", request_properties.request_description == "this is a test", "Fifth workload group", hourofday(now()) between (17 .. 23), "Sixth workload group", "default")"}

Set a policy with a single workload group

Set a policy which, based on the evaluation of a composed condition, assigns the user to either a custom or to default workload group:

.alter cluster policy request_classification '{"IsEnabled":true}' <|
    iff(request_properties.current_application == "Kusto.Explorer" and request_properties.request_type == "Query",
        "Ad-hoc queries",
        "default")

Output

PolicyName EntityName Policy ChildEntities EntityType
ClusterRequestClassificationPolicy {"ClassificationProperties": ["current_application", "request_type" ],"IsEnabled": true, "ClassificationFunction": "iff(request_properties.current_application == "Kusto.Explorer" and request_properties.request_type == "Query","Ad-hoc queries","default")"}
