SNMP Information Monitor (10003 / 20003)

Description

This Module reports SNMP polling information. This information is provided per exporter-interface (exp_ip-ifIndex) pair.
The following SNMP OIDs are polled and reported:
    1.
    Interface index (ifIndex) – OID - 1.3.6.1.2.1.2.2.1.1
    2.
    Interface description (ifDescr) - OID 1.3.6.1.2.1.2.2.1.2
    3.
    Interface type (ifType) - OID 1.3.6.1.2.1.2.2.1.3
    4.
    Size of the largest packet (ifMtu) - OID 1.3.6.1.2.1.2.2.1.4
    5.
    Interface bandwidth (ifSpeed), (ifHighSpeed) - OID 1.3.6.1.2.1.2.2.1.5, OID 1.3.6.1.2.1.31.1.1.1.15
    6.
    Interface physical address (ifPhysAddress) - OID 1.3.6.1.2.1.2.2.1.6
    7.
    Desired state of the interface (ifAdminStatus) - OID 1.3.6.1.2.1.2.2.1.7
    8.
    Operational state of the interface (ifOperStatus) - OID 1.3.6.1.2.1.2.2.1.8
    9.
    IP address to which this entry's addressing information pertains (ipAdEntAddr) - OID 1.3.6.1.2.1.4.20.1.1
    10.
    Index value which uniquely identifies the interface to which this entry is applicable (ipAdEntIfIndex) – OID 1.3.6.1.2.1.4.20.1.2
    11.
    Interface InetAddressType (ipAddressAddrType) - OID 1.3.6.1.2.1.4.34.1.1
    12.
    Interface InetAddress (ipAddressAddr) - OID 1.3.6.1.2.1.4.34.1.2
    13.
    The index value that uniquely identifies the interface to which this entry is applicable (ipAddressIfIndex) - OID 1.3.6.1.2.1.4.34.1.3
    14.
    Interface duplex status (dot3StatsDuplexStatus) - OID 1.3.6.1.2.1.10.7.2.1.19
    15.
    An index value that uniquely identifies an interface to an ethernet-like medium (dot3StatsIndex) - OID 1.3.6.1.2.1.10.7.2.1.1
    16.
    Interface name (ifName) - OID 1.3.6.1.2.1.31.1.1.1.1
    17.
    Interface alias (ifAlias) - OID 1.3.6.1.2.1.31.1.1.1.18
