Forwarder Status¶

Forwarder Status is a module of NFD Management protocol.
It provides:

• a dataset of forwarder version information and global counters

Forwarder Status datasets are available under namespace ndn:/localhost/nfd/status.

General Status Dataset¶

General Status is published as a Status Dataset at ndn:/localhost/nfd/status/general.

GeneralStatus ::= NfdVersion
                  RouterName
                  StartTimestamp
                  CurrentTimestamp
                  NNameTreeEntries
                  NFibEntries
                  NPitEntries
                  NMeasurementsEntries
                  NCsEntries
                  NInInterests
                  NInDatas
                  NInNacks
                  NOutInterests
                  NOutDatas
                  NOutNacks

NfdVersion ::= NFD-VERSION-TYPE TLV-LENGTH
                 UTF-8 string

RouterName ::= ROUTER-NAME-TYPE TLV-LENGTH
                 Name
                 Name
                 Name

(other TLVs have nonNegativeInteger as value)

• NfdVersion: NFD version; this is usually same as nfd --version output, but the daemon MAY hide its version and return an empty string
• RouterName: network name, site name, and router name from configuration
• StartTimestamp: timestamp (milliseconds since UNIX epoch) when forwarder starts
• CurrentTimestamp: timestamp (milliseconds since UNIX epoch) of current time
• NNameTreeEntries: number of NameTree entries
• NFibEntries: number of FIB entries
• NPitEntries: number of PIT entries
• NMeasurementsEntries: number of Measurements entries
• NCsEntries: number of CS entries
• NInInterests: number of incoming Interest packets processed since forwarder starts
• NInDatas: number of incoming Data packets processed since forwarder starts
• NInNacks: number of incoming Nack packets processed since forwarder starts
• NOutInterests: number of outgoing Interest packets processed since forwarder starts
• NOutDatas: number of outgoing Data packets processed since forwarder starts
• NOutNacks: number of outgoing Nack packets processed since forwarder starts
