# Measurement Status 

 Measurement Status is module of [[Management|NFD Management protocol]]. 
 It provides measurement table entries for a given name prefix. 
 The strategy responsible for the name prefix need to support measurement queries. 

 Measurements for a prefix is published as a [[StatusDataset|Status Dataset]] at: ndn:/localhost/nfd/measurements/query/ 

 ## Control Parameters 

 ControlParameters fields: 

     Name (required) 

 Name is the prefix for which the measurement query is made. 
 A forwarder MAY impose a limit on the length of name prefix. The current limit in NFD is 32 name components. 
 If Name exceeds this limit, the command fails with code 414. 

 ## Measurement Entry Dataset 

 Each measurement entry is represented by **MeasurementEntry** block: 

     MeasurementEntry MeasurementStatus := MEASUREMENT-ENTRY-TYPE TLV-LENGTH 
                           
                            Name 
                           
                            StrategyInfo 

 * **Name** is the prefix for which the query was made 
 * **StrategyInfo** is the measurement info provided by the strategy responsible for the given name 

 ## TLV-TYPE assignments 

 Type                                          | Assigned number     | Assigned number (hex) 
 ------------------------------------------- | ----------------- | --------------------- 
 MeasurementEntry                              | 128                 | 0x80 
 StrategyInfo                                  | 129                 | 0x81
