Request

GET streamsets/{webId}/recorded

URL Parameters

• webId

  The ID of an element, event frame or attribute, which is the base element or parent of all the stream attributes. See WebID for more information.

• startTime

  An optional start time. The default is '*-1d' for element attributes and points. For event frame attributes, the default is the event frame's start time, or '*-1d' if that is not set. See Time Strings for more information.

• endTime

  An optional end time. The default is '*' for element attributes and points. For event frame attributes, the default is the event frame's end time, or '*' if that is not set. Note that if endTime is earlier than startTime, the resulting values will be in time-descending order. See Time Strings for more information.

• timeZone

  The time zone in which the time string will be interpreted. This parameter will be ignored if a time zone is specified in the time string. If no time zone is specified in either places, the PI Web API server time zone will be used. See Time Zone for more information.

• boundaryType

  An optional value that determines how the times and values of the returned end points are determined. The default is 'Inside'. See Boundary Type for more information.

• filterExpression

  An optional string containing a filter expression. Expression variables are relative to the data point. Use '.' to reference the containing attribute. The default is no filtering.

• includeFilteredValues

  Specify 'true' to indicate that values which fail the filter criteria are present in the returned data at the times where they occurred with a value set to a 'Filtered' enumeration value with bad status. Repeated consecutive failures are omitted.

• nameFilter

  The name query string used for filtering attributes. The default is no filter. See Query String for more information.

• categoryName

  Specify that included attributes must have this category. The default is no category filter.

• templateName

  Specify that included attributes must be members of this template. The default is no template filter.

• showExcluded

  Specified if the search should include attributes with the Excluded property set. The default is 'false'.

• showHidden

  Specified if the search should include attributes with the Hidden property set. The default is 'false'.

• searchFullHierarchy

  Specifies if the search should include attributes nested further than the immediate attributes of the searchRoot. The default is 'false'.

• maxCount

  The maximum number of values to be returned. The default is 1000.

• sortField

  The field or property of the object used to sort the returned collection. For better performance, by default no sorting is applied. 'Name' is the only supported field by which to sort. See Sort Field for more information.

• sortOrder

  The order that the returned collection is sorted. The default is 'Ascending' See Sort Order for more information.

• selectedFields

  List of fields to be returned in the response, separated by semicolons (;). If this parameter is not specified, all available fields will be returned. See Selected Fields for more information.

• webIdType

  Optional parameter. Used to specify the type of WebID. Useful for URL brevity and other special cases. Default is the value of the configuration item "WebIDType". See WebID Type for more information.

Status Codes

200: Recorded values of the streams that meet the specified conditions.
