mrtg-mibhelp - A Table of some interesting OIDs

This File Contains a collection of interesting MIB Entries ... mrtg knows about their names ... depending on the ASN.1 Syntax you may have to put gauge into the Options[]: parameter.

For information about how to create a Target[]: parameter which references these MIB entries, please consult mrtg-reference.

 Descriptor:            ifOperStatus
 Identifier:            1.3.6.1.2.1.2.2.1.8
 ASN.1 Syntax:          INTEGER
 Enumeration:           up 1, down 2, testing 3

The current operational state of the interface. The testing(3) state indicates that no operational packets can be passed.

 Descriptor:            ifAdminStatus
 Identifier:            1.3.6.1.2.1.2.2.1.7
 ASN.1 Syntax:          INTEGER
 Enumeration:           up 1, down 2, testing 3

The current administrative state of the interface. The testing(3) state indicates that no operational packets can be passed.

 Descriptor:            ifInOctets
 Identifier:            1.3.6.1.2.1.2.2.1.10
 ASN.1 Syntax:          Counter32

The total number of octets received on the interface, including framing characters.

 Descriptor:            ifInUcastPkts
 Identifier:            1.3.6.1.2.1.2.2.1.11
 ASN.1 Syntax:          Counter32

The number of subnetwork-unicast packets delivered to a higher-layer protocol.

 Descriptor:            ifInNUcastPkts
 Identifier:            1.3.6.1.2.1.2.2.1.12
 ASN.1 Syntax:          Counter32

The number of non-unicast (i.e., subnetwork- broadcast or subnetwork-multicast) packets delivered to a higher-layer protocol.

 Descriptor:            ifInDiscards
 Identifier:            1.3.6.1.2.1.2.2.1.13
 ASN.1 Syntax:          Counter32

The number of inbound packets which were chosen to be discarded even though no errors had been detected to prevent their being deliverable to a higher-layer protocol. One possible reason for discarding such a packet could be to free up buffer space.

Descriptor: ifInErrors Identifier: 1.3.6.1.2.1.2.2.1.14 ASN.1 Syntax: Counter32

The number of inbound packets that contained errors preventing them from being deliverable to a higher-layer protocol.

Descriptor: ifInUnknownProtos Identifier: 1.3.6.1.2.1.2.2.1.15 ASN.1 Syntax: Counter32

The number of packets received via the interface which were discarded because of an unknown or unsupported protocol.

Descriptor: ifOutOctets Identifier: 1.3.6.1.2.1.2.2.1.16 ASN.1 Syntax: Counter32

The total number of octets transmitted out of the interface, including framing characters.

 Descriptor:             ifOutUcastPkts
 Identifier:            1.3.6.1.2.1.2.2.1.17
 ASN.1 Syntax:          Counter32

The total number of packets that higher-level protocols requested be transmitted to a subnetwork-unicast address, including those that were discarded or not sent.

 Descriptor:             ifOutNUcastPkts
 Identifier:            1.3.6.1.2.1.2.2.1.18
 ASN.1 Syntax:          Counter32

The total number of packets that higher-level protocols requested be transmitted to a non- unicast (i.e., a subnetwork-broadcast or subnetwork-multicast) address, including those that were discarded or not sent.

 Descriptor:             ifOutDiscards
 Identifier:            1.3.6.1.2.1.2.2.1.19
 ASN.1 Syntax:          Counter32

The number of outbound packets which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space.

 Descriptor:             ifOutErrors
 Identifier:            1.3.6.1.2.1.2.2.1.20
 ASN.1 Syntax:          Counter32

The number of outbound packets that could not be transmitted because of errors.

 Descriptor:             ifOutQLen
 Identifier:            1.3.6.1.2.1.2.2.1.21
 ASN.1 Syntax:          Unsigned32

The length of the output packet queue (in packets).

 'frInOctets' => '1.3.6.1.2.1.10.32.2.1.9'
 'frOutOctets' => '1.3.6.1.2.1.10.32.2.1.7'

which when used in the form:

 frInOctets.pp.dd&frOutOctets.pp.dd:community@cisco.router

where pp is the physical port that the frame relay pvc is defined on and dd is the DLCI of the pvc gets you the in and out octets for just that pvc.

The return values of ifAdminStatus and ifOperStatus are not very usefull for graphing. Use ifOperHack and ifAdminHack instead. They return 1 for UP and 0 otherwise.

Note these are not real MIB entities but mrtg hacks

will return 0 and 1 respectively
