| 5 | 1 | Junxiao Shi | **Forwarder Status** is a module of [[Management|NFD Management protocol]]. |
| 6 | 5 | Junxiao Shi | It provides: |
| 7 | 1 | Junxiao Shi | |
| 8 | 5 | Junxiao Shi | * a dataset of forwarder version information and global counters |
| 9 | 1 | Junxiao Shi | |
| 10 | 5 | Junxiao Shi | Forwarder Status datasets are available under namespace `ndn:/localhost/nfd/status`. |

| 13 | 1 | Junxiao Shi | |
| 14 | 5 | Junxiao Shi | General Status is published as a [[StatusDataset|Status Dataset]] at `ndn:/localhost/nfd/status/general`. |

||
| 45 | 20 | Davide Pesavento | * **NInInterests**: number of incoming Interest packets processed since the forwarder started |
| 46 | * **NInData**: number of incoming Data packets processed since the forwarder started |
||
| 47 | * **NInNacks**: number of incoming Nack packets processed since the forwarder started |
||
| 48 | * **NOutInterests**: number of outgoing Interest packets processed since the forwarder started |
||
| 49 | * **NOutData**: number of outgoing Data packets processed since the forwarder started |
||
| 50 | * **NOutNacks**: number of outgoing Nack packets processed since the forwarder started |
||
| 51 | 13 | Ju Pan | * **NSatisfiedInterests**: number of satisfied Interests, incremented when a PIT entry that has been satisfied is being removed |
| 52 | * **NUnsatisfiedInterests**: number of unsatisfied Interests, incremented when a PIT entry that has not been satisfied is being removed |
