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 the reference manpage.

ifOperStatus
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.

ifAdminStatus
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.

ifInOctets
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.

ifInUcastPkts
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.

ifInNUcastPkts
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.

ifInDiscards
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.

ifInErrors
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.

ifInUnknownProtos
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.

ifOutOctets
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.

ifOutUcastPkts
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.

ifOutNUcastPkts
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.

ifOutDiscards
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.

ifOutErrors
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.

ifOutQLen
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
From: Simon Ferrett <simonf@world.net> '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.

ifAdminHack and ifOperHack
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 Tobias Oetiker <oetiker@ee.ethz.ch>
