Field Name

Field Description

Input

Information about received packets:

  • Packets(snmpInPkts)—Total number of messages delivered to the SNMP entity from the transport service.
  • Bad versions—(snmpInBadVersions) Total number of messages delivered to the SNMP entity that were for an unsupported SNMP version.
  • Bad community names—(snmpInBadCommunityNames) Total number of messages delivered to the SNMP entity that used an SNMP community name not known to the entity.
  • Bad community uses—(snmpInBadCommunityUses) Total number of messages delivered to the SNMP entity that represented an SNMP operation that was not allowed by the SNMP community named in the message.
  • ASN parse errors—(snmpInASNParseErrs) Total number of ASN.1 or BER errors encountered by the SNMP entity when decoding received SNMP messages.
  • Too bigs—(snmpInTooBigs) Total number of SNMP PDUs delivered to the SNMP entity with an error status field of tooBig.
  • No such names—(snmpInNoSuchNames).Total number of SNMP PDUs delivered to the SNMP entity with an error status field of noSuchName.
  • Bad values—(snmpInBadValues) Total number of SNMP PDUs delivered to the SNMP entity with an error status field of badValue.
  • Read onlys—(snmpInReadOnlys) Total number of valid SNMP PDUs delivered to the SNMP entity with an error status field of readOnly. Only incorrect implementations of SNMP generate this error.

Input (continued)

  • General errors—(snmpInGenErrs) Total number of SNMP PDUs delivered to the SNMP entity with an error status field ofgenErr.
  • Total requests varbinds—(snmpInTotalReqVars) Total number of MIB objects retrieved successfully by the SNMP entity as a result of receiving valid SNMP GetRequest and GetNext PDUs.
  • Total set varbinds—(snmpInSetVars) Total number of MIB objects modified successfully by the SNMP entity as a result of receiving valid SNMP SetRequest PDUs.
  • Get requests—(snmpInGetRequests) Total number of SNMPGetRequest PDUs that have been accepted and processed by the SNMP entity.
  • Get nexts—(snmpInGetNexts) Total number of SNMP GetNext PDUs that have been accepted and processed by the SNMP entity.
  • Set requests—(snmpInSetRequests) Total number of SNMP SetRequest PDUs that have been accepted and processed by the SNMP entity.
  • Get responses—(snmpInGetResponses) Total number of SNMP GetResponse PDUs that have been accepted and processed by the SNMP entity.
  • Traps—(snmpInTraps) Total number of SNMP traps generated by the SNMP entity.
  • Silent drops—(snmpSilentDrops) Total number of GetRequest, GetNextRequest, GetBulkRequest, SetRequests, and InformRequest PDUs delivered to the SNMP entity that were silently dropped because the size of a reply containing an alternate response PDU with an empty variable-bindings field was greater than either a local constraint or the maximum message size associated with the originator of the requests.
  • Proxy drops.—(snmpProxyDrops) Total number of GetRequest, GetNextRequest, GetBulkRequest, SetRequests, and InformRequest PDUs delivered to the SNMP entity that were silently dropped because the transmission of the message to a proxy target failed in such a way (other than a timeout) that no response PDU could be returned.
  • Commit pending drops—Number of SNMP packets forSet requests dropped because of a previous pending SNMP Set request on the committed configuration.
  • Throttle drops—Number of SNMP packets for any requests dropped reaching the throttle limit.

V3 Input

Information about SNMP version 3 packets:

  • Unknown security models—(snmpUnknownSecurityModels) Total number of packets received by the SNMP engine that were dropped because they referenced a security model that was not known to or supported by the SNMP engine.
  • Invalid messages—(snmpInvalidMsgs) Number of packets received by the SNMP engine that were dropped because there were invalid or inconsistent components in the SNMP message.
  • Unknown pdu handlers—(snmpUnknownPDUHandlers) Number of packets received by the SNMP engine that were dropped because the PDU contained in the packet could not be passed to an application responsible for handling the PDU type.
  • Unavailable contexts—(snmpUnavailableContexts) Number of requests received for a context that is known to the SNMP engine, but is currently unavailable.
  • Unknown contexts—(snmpUnknownContexts) Total number of requests received for a context that is unknown to the SNMP engine.
  • Unsupported security levels—(usmStatsUnsupportedSecLevels) Total number of packets received by the SNMP engine which were dropped because they requested a security level unknown to the SNMP engine (or otherwise unavailable).
  • Not in time windows—(usmStatsNotInTimeWindows) Total number of packets received by the SNMP engine that were dropped because they appeared outside of the authoritative SNMP engine's window.
  • Unknown user names—(usmStatsUnknownUserNames) Total number of packets received by the SNMP engine that were dropped because they referenced a user that was not known to the SNMP engine.
  • Unknown engine ids—(usmStatsUnknownEngineIDs) Total number of packets received by the SNMP engine that were dropped because they referenced an SNMP engine ID that was not known to the SNMP engine.
  • Wrong digests—(usmStatsWrongDigests) Total number of packets received by the SNMP engine that were dropped because they didn't contain the expected digest value.
  • Decryption errors—(usmStatsDecryptionErrors) Total number of packets received by the SNMP engine that were dropped because they could not be decrypted.

Output

Information about transmitted packets:

  • Packets—(snmpOutPkts) Total number of messages passed from the SNMP entity to the transport service.
  • Too bigs—(snmpOutTooBigs) Total number of SNMP PDUs generated by the SNMP entity with an error status field of tooBig.
  • No such names—(snmpOutNoSuchNames) Total number of SNMP PDUs delivered to the SNMP entity with an error status field of noSuchName.
  • Bad values—(snmpOutBadValues) Total number of SNMP PDUs generated by the SNMP entity with an error status field of badValue.
  • General errors—(snmpOutGenErrs) Total number of SNMP PDUs generated the SNMP entity with an error status field of genErr.
  • Get requests—(snmpOutGetRequests) Total number of SNMP GetRequest PDUs generated by the SNMP entity.
  • Get nexts—(snmpOutGetNexts) Total number of SNMP GetNext PDUs generated by the SNMP entity.
  • Set requests—(snmpOutSetRequests) Total number of SNMP SetRequest PDUs generated by the SNMP entity.
  • Get responses—(snmpOutGetResponses) Total number of SNMP GetResponse PDUs generated by the SNMP entity.
  • Traps—(snmpOutTraps) Total number of SNMP traps generated by the SNMP entity.
