Comparator cd not and or Description Contained in. Negates the operator that follows. Applicable data types List of any type All All the conditions in the parentheses that follow All must be true in order for the request to evaluate as true. NOTE: The default for multiple filters is to AND them, so the use of and is optional unless you are using both and and or in the filter expression. At least one of the conditions in the parentheses All that follow must be true in order for the request to evaluate as true. Example ?server_addresses=cd. {"1.2.3.4","5.6.7.8"} True if the values in the server addresses list are all either 1.2.3.4 or 5.6.7.8. ?resource_type=not.in. (Operator,Administrator,VM Administrator) True if the value of role_id is not Operator, Administrator, or VM Administrator. ? and=(size.gt.50,performance_poli cy_id.eq.default_high) True if the value of size is greater than 50 MB and the value of performance_policy is High. ? or=(size.gt.50,performance_polic y_id.eq.default_high) True if either the value of size is greater than 50 MB or the value of performance_policy is High or both. Sorting response data Use the order request parameter to specify sort criteria for one attribute in a list of resources returned by a collection query. The order parameter works like an SQL Order By clause. You can specify one of these sort orders for the attribute: • asc: (Default) Sorts the response data in ascending order. • desc: Sorts the response data in descending order. Sorting is case insensitive for any property called name. Syntax As the first parameter on the request URI: ?order= As a subsequent parameter on the request URI: &order= where is defined by the following syntax: prop_expr1[.asc|.desc],[prop_expr2[.asc|.desc]... where: • prop_expr1 and prop_expr2 are attribute names that are defined for the resource being queried. • asc and desc are case insensitive. Retrieving values for all alerts, sorted by state The following request retrieves values for the id, description, and alert_state attributes for all alert instances and sorts this information by alert_state in ascending order.
