Expand description

Ip layer counters.

Fields§

§deliver_unicast: Counter

Count of incoming IP unicast packets delivered.

§deliver_multicast: Counter

Count of incoming IP multicast packets delivered.

§dispatch_receive_ip_packet: Counter

Count of incoming IP packets that are dispatched to the appropriate protocol.

§dispatch_receive_ip_packet_other_host: Counter

Count of incoming IP packets destined to another host.

§receive_ip_packet: Counter

Count of incoming IP packets received by the stack.

§send_ip_packet: Counter

Count of sent outgoing IP packets.

§forwarding_disabled: Counter

Count of packets to be forwarded which are instead dropped because forwarding is disabled.

§forward: Counter

Count of incoming packets forwarded to another host.

§no_route_to_host: Counter

Count of incoming packets which cannot be forwarded because there is no route to the destination host.

§mtu_exceeded: Counter

Count of incoming packets which cannot be forwarded because the MTU has been exceeded.

§ttl_expired: Counter

Count of incoming packets which cannot be forwarded because the TTL has expired.

§receive_icmp_error: Counter

Count of ICMP error messages received.

§fragment_reassembly_error: Counter

Count of IP fragment reassembly errors.

§need_more_fragments: Counter

Count of IP fragments that could not be reassembled because more fragments were needed.

§invalid_fragment: Counter

Count of IP fragments that could not be reassembled because the fragment was invalid.

§fragment_cache_full: Counter

Count of IP fragments that could not be reassembled because the stack’s per-IP-protocol fragment cache was full.

§parameter_problem: Counter

Count of incoming IP packets not delivered because of a parameter problem.

§unspecified_destination: Counter

Count of incoming IP packets with an unspecified destination address.

§unspecified_source: Counter

Count of incoming IP packets with an unspecified source address.

§dropped: Counter

Count of incoming IP packets dropped.

§tx_illegal_loopback_address: Counter

Number of frames rejected because they’d cause illegal loopback addresses on the wire.

§version_rx: I::RxCounters

Version specific rx counters.

§multicast_no_interest: Counter

Count of incoming IP multicast packets that were dropped because The stack doesn’t have any sockets that belong to the multicast group, and the stack isn’t configured to forward the multicast packet.

§invalid_cached_conntrack_entry: Counter

Count of looped-back packets that held a cached conntrack entry that could not be downcasted to the expected type. This would happen if, for example, a packet was modified to a different IP version between EGRESS and INGRESS.

§fragmentation: FragmentationCounters

IP fragmentation counters.
