|---|---|---|---|
| 2 | |||
| 3 | **Forwarder Status** is a module of [[Management|NFD Management protocol]]. |
||
| 4 | It publishes version information and global counters of the forwarder. |
||
| 5 | |||
| 6 | Forwarder Status is published as a single Data packet under `ndn:/localhost/nfd/status`. |
||
| 7 | Consumer should send Interest `ndn:/localhost/nfd/status`, MustBeFresh=yes. |
||
| 8 | |||
| 9 | The Content of the response Data packet is a sequence of these blocks: |
||
| 10 | |||
| 11 | 3 | Junxiao Shi | * **NfdApiVersion** nonNegativeInteger: NFD API version |
| 12 | * **SoftwareVersion** UTF-8 string: NFD software version; this is usually same as `nfd --version` output, but the daemon MAY hide its version and return an empty string |
||
| 13 | 2 | Alex Afanasyev | * **StartTimestamp** nonNegativeInteger: UNIX timestamp (in milliseconds) when NFD starts |
| 14 | * **CurrentTimestamp** nonNegativeInteger: UNIX timestamp (in milliseconds) of current time |
||
| 15 | 1 | Junxiao Shi | * **NNameTreeEntries** nonNegativeInteger: number of NameTree entries |
| 16 | * **NFibEntries** nonNegativeInteger: number of FIB entries |
||
| 17 | * **NPitEntries** nonNegativeInteger: number of PIT entries |
||
| 18 | * **NMeasurementsEntries** nonNegativeInteger: number of Measurements entries |
||
| 19 | * **NCsEntries** nonNegativeInteger: number of CS entries |
||
| 20 | * **NInInterests** nonNegativeInteger: number of incoming Interests processed since forwarder starts |
||
| 21 | * **NInDatas** nonNegativeInteger: number of incoming Datas processed since forwarder starts |
||
| 22 | * **NOutInterests** nonNegativeInteger: number of outgoing Interests processed since forwarder starts |
||
| 23 | * **NOutDatas** nonNegativeInteger: number of outgoing Datas processed since forwarder starts |
||
