# Forwarder Status
{{>toc}}
**Forwarder Status** is a module of [[Management|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 [[StatusDataset|Status Dataset]] at `ndn:/localhost/nfd/status/general`.
GeneralStatus = NfdVersion
StartTimestamp
CurrentTimestamp
NNameTreeEntries
NFibEntries
NPitEntries
NMeasurementsEntries
NCsEntries
NInInterests
NInData
NInNacks
NOutInterests
NOutData
NOutNacks
NSatisfiedInterests
NUnsatisfiedInterests
NfdVersion = NFD-VERSION-TYPE TLV-LENGTH
UTF-8-STRING UTF-8 string
(all other (other TLVs have nonNegativeInteger as value)
* **NfdVersion**: NFD version; this is usually same as `nfd --version` output, but the forwarder MAY hide its version and return an empty string
* **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
* **NInData**: 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
* **NOutData**: number of outgoing Data packets processed since forwarder starts
* **NOutNacks**: number of outgoing Nack packets processed since forwarder starts
* **NSatisfiedInterests**: number of satisfied Interests, incremented when a PIT entry that has been satisfied is being removed
* **NUnsatisfiedInterests**: number of unsatisfied Interests, incremented when a PIT entry that has not been satisfied is being removed
