Discovery rules

Name Description Type Key and additional info
CPU Discovery

If your IOS device has several CPUs, you must use CISCO-PROCESS-MIB and its object cpmCPUTotal5minRev from the table called cpmCPUTotalTable,

indexed with cpmCPUTotalIndex.

This table allows CISCO-PROCESS-MIB to keep CPU statistics for different physical entities in the router,

like different CPU chips, group of CPUs, or CPUs in different modules/cards.

In case of a single CPU, cpmCPUTotalTable has only one entry.

Items collected

Group Name Description Type Key and additional info
CPU #{#SNMPINDEX}: CPU utilization

MIB: CISCO-PROCESS-MIB

The cpmCPUTotal5minRev MIB object provides a more accurate view of the performance of the router over time than the MIB objects cpmCPUTotal1minRev and cpmCPUTotal5secRev . These MIB objects are not accurate because they look at CPU at one minute and five second intervals, respectively. These MIBs enable you to monitor the trends and plan the capacity of your network. The recommended baseline rising threshold for cpmCPUTotal5minRev is 90 percent. Depending on the platform, some routers that run at 90 percent, for example, 2500s, can exhibit performance degradation versus a high-end router, for example, the 7500 series, which can operate fine.

Network interfaces Interface {#IFNAME}({#IFALIAS}): Duplex status

MIB: EtherLike-MIB

The current mode of operation of the MAC

entity. 'unknown' indicates that the current

duplex mode could not be determined.

Management control of the duplex mode is

accomplished through the MAU MIB. When

an interface does not support autonegotiation,

or when autonegotiation is not enabled, the

duplex mode is controlled using

ifMauDefaultType. When autonegotiation is

supported and enabled, duplex mode is controlled

using ifMauAutoNegAdvertisedBits. In either

case, the currently operating duplex mode is

reflected both in this object and in ifMauType.

Note that this object provides redundant

information with ifMauType. Normally, redundant

objects are discouraged. However, in this

instance, it allows a management application to

determine the duplex status of an interface

without having to know every possible value of

ifMauType. This was felt to be sufficiently

valuable to justify the redundancy.

SNMP net.if.duplex[dot3StatsDuplexStatus.{#SNMPINDEX}]
Network interfaces Interface {#IFNAME}({#IFALIAS}): Operational status

MIB: IF-MIB

The current operational state of the interface.

- The testing(3) state indicates that no operational packet scan be passed

- If ifAdminStatus is down(2) then ifOperStatus should be down(2)

- If ifAdminStatus is changed to up(1) then ifOperStatus should change to up(1) if the interface is ready to transmit and receive network traffic

- It should change todormant(5) if the interface is waiting for external actions (such as a serial line waiting for an incoming connection)

- It should remain in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state

- It should remain in the notPresent(6) state if the interface has missing(typically, hardware) components.

SNMP net.if.status[ifOperStatus.{#SNMPINDEX}]
Network interfaces Interface {#IFNAME}({#IFALIAS}): Bits received

MIB: IF-MIB

The total number of octets received on the interface, including framing characters. This object is a 64-bit version of ifInOctets.

Discovery rules

Name Description Type Key and additional info
CPU Discovery

If your IOS device has several CPUs, you must use CISCO-PROCESS-MIB and its object cpmCPUTotal5minRev from the table called cpmCPUTotalTable,

indexed with cpmCPUTotalIndex.

This table allows CISCO-PROCESS-MIB to keep CPU statistics for different physical entities in the router,

like different CPU chips, group of CPUs, or CPUs in different modules/cards.

In case of a single CPU, cpmCPUTotalTable has only one entry.

- If ifAdminStatus is down(2) then ifOperStatus should be down(2)

- If ifAdminStatus is changed to up(1) then ifOperStatus should change to up(1) if the interface is ready to transmit and receive network traffic

- It should change todormant(5) if the interface is waiting for external actions (such as a serial line waiting for an incoming connection)

- It should remain in the down(2) state if and only if there is a fault that prevents it from going to the up(1) state

- It should remain in the notPresent(6) state if the interface has missing(typically, hardware) components.

General System object ID

MIB: SNMPv2-MIB

The vendor's authoritative identification of the network management subsystem contained in the entity. This value is allocated within the SMI enterprises subtree (1.3.6.1.4.1) and provides an easy and unambiguous means for determiningwhat kind of box' is being managed. For example, if vendorFlintstones, Inc.' was assigned the subtree1.3.6.1.4.1.4242, it could assign the identifier 1.3.6.1.4.1.4242.1.1 to its Fred Router'.</p> |SNMP |system.objectid[sysObjectID.0]<p>**Preprocessing**:</p><p>- DISCARD_UNCHANGED_HEARTBEAT:12h`

SNMP system.net.uptime[sysUpTime.0]

Preprocessing:

- MULTIPLIER: 0.01

Status Uptime (hardware)

MIB: HOST-RESOURCES-MIB

The amount of time since this host was last initialized. Note that this is different from sysUpTime in the SNMPv2-MIB [RFC1907] because sysUpTime is the uptime of the network management portion of the system.
