=head1 NAME mrtg-mibhelp - A Table of some interesting OIDs =head1 OVERVIEW 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 B into the B parameter. For information about how to create a B parameter which references these MIB entries, please consult L. =head1 MIB LIST =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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. =head2 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). =head2 frInOctets From: Simon Ferrett '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. =head2 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 =head2 PseudoZero and PseudoOne will return 0 and 1 respectively Note these are not real MIB entities but mrtg hacks =head1 AUTHOR Tobias Oetiker Etobi@oetiker.chE
