Win32_PerfFormattedData_Tcpip_IPv4 Class

The IP performance object consists of counters that measure the rates at which IP datagrams are sent and received by using IP protocols. It also includes counters that monitor IP protocol errors.
Namespace value is root/CIMV2.
WMI Provider value is WmiPerfInst.


Properties

  • Caption
  • A short textual description (one-line string) for the statistic or metric.

  • DatagramsForwardedPersec
  • Datagrams Forwarded/sec is the rate, in incidents per second, at which attemps were made to find routes to forward input datagrams their final destination, because the local server was not the final IP destination. In servers that do not act as IP Gateways, this rate includes only packets that were source-routed via this entity, where the source-route option processing was successful.

  • DatagramsOutboundDiscarded
  • Datagrams Outbound Discarded is the number of output IP datagrams that were discarded even though no problems were encountered to prevent their transmission to their destination (for example, lack of buffer space). This counter includes datagrams counted in Datagrams Forwarded/sec that meet this criterion.

  • DatagramsOutboundNoRoute
  • Datagrams Outbound No Route is the number of IP datagrams that were discarded because no route could be found to transmit them to their destination. This counter includes any packets counted in Datagrams Forwarded/sec that meet this `no route' criterion.

  • DatagramsPersec
  • Datagrams/sec is the rate, in incidents per second, at which IP datagrams were received from or sent to the interfaces, including those in error. Forwarded datagrams are not included in this rate.

  • DatagramsReceivedAddressErrors
  • Datagrams Received Address Errors is the number of input datagrams that were discarded because the IP address in their IP header destination field was not valid for the computer. This count includes invalid addresses (for example, 0.0. 0.0) and addresses of unsupported Classes (for example, Class E). For entities that are not IP gateways and do not forward datagrams, this counter includes datagrams that were discarded because the destination address was not a local address.

  • DatagramsReceivedDeliveredPersec
  • Datagrams Received Delivered/sec is the rate, in incidents per second, at which input datagrams were successfully delivered to IP user-protocols, including Internet Control Message Protocol (ICMP).

  • DatagramsReceivedDiscarded
  • Datagrams Received Discarded is the number of input IP datagrams that were discarded even though problems prevented their continued processing (for example, lack of buffer space). This counter does not include any datagrams discarded while awaiting re-assembly.

  • DatagramsReceivedHeaderErrors
  • Datagrams Received Header Errors is the number of input datagrams that were discarded due to errors in the IP headers, including bad checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, etc.

  • DatagramsReceivedPersec
  • Datagrams Received/sec is the rate, in incidents per second, at which IP datagrams are received from the interfaces, including those in error. Datagrams Received/sec is a subset of Datagrams/sec.

  • DatagramsReceivedUnknownProtocol
  • Datagrams Received Unknown Protocol is the number of locally-addressed datagrams that were successfully received but were discarded because of an unknown or unsupported protocol.

  • DatagramsSentPersec
  • Datagrams Sent/sec is the rate, in incidents per second, at which IP datagrams were supplied for transmission by local IP user-protocols (including ICMP). This counter does not include any datagrams counted in Datagrams Forwarded/sec. Datagrams Sent/sec is a subset of Datagrams/sec.

  • Description
  • A textual description of the statistic or metric.

  • FragmentationFailures
  • Fragmentation Failures is the number of IP datagrams that were discarded because they needed to be fragmented at but could not be (for example, because the `Don't Fragment' flag was set).

  • FragmentedDatagramsPersec
  • Fragmented Datagrams/sec is the rate, in incidents per second, at which datagrams are successfully fragmented.

  • FragmentReassemblyFailures
  • Fragment Re-assembly Failures is the number of failures detected by the IP reassembly algorithm, such as time outs, errors, etc. This is not necessarily a count of discarded IP fragments since some algorithms (notably RFC 815) lose track of the number of fragments by combining them as they are received.

  • FragmentsCreatedPersec
  • Fragments Created/sec is the rate, in incidents per second, at which IP datagram fragments were generated as a result of fragmentation.

  • FragmentsReassembledPersec
  • Fragments Re-assembled/sec is the rate, in incidents per second, at which IP fragments were successfully reassembled.

  • FragmentsReceivedPersec
  • Fragments Received/sec is the rate, in incidents per second, at which IP fragments that need to be reassembled at this entity are received.

  • Frequency_Object
  • Not applicable.

  • Frequency_PerfTime
  • Not applicable.

  • Frequency_Sys100NS
  • Not applicable.

  • Name
  • The Name property defines the label by which the statistic or metric is known. When subclassed, the property can be overridden to be a Key property.

  • Timestamp_Object
  • Not applicable.

  • Timestamp_PerfTime
  • Not applicable.

  • Timestamp_Sys100NS
  • Not applicable.
