    HI All,

     

    How to know the OID's which calculate Bandwidth utilization in CISCO devices(Interfaces) in CA Spectrum.Below details require, also want to know whether OID will change for different cisco models ?

     

    Bandwidth Utilization IN,OUT,Average: Cisco Interfaces

    Memory and CPU : on Cisco devices

     

    Thanks in Advanced !!

    For most devices data on interfaces comes from the RFC12!3_MIB

    These OIDs may give you what you want.

    ifInOctets1.3.6.1.2.1.2.2.1.10
    ifOutOctets

    1.3.6.1.2.1.2.2.1.16

    and these expressions

    (inoctets * 800) / (duration * $ifSpeed_in)

    (outoctets * 800) / (duration * $ifSpeed_out)

    Thanks David, i believe the OID's for all the models !!

    Can you please share Memory and CPU utilization for CIsco Models.


    Thanks,

    Venu

    'all' ah no but here is for most

    CISCO_MEMORY_POOL_MIB.ciscoMemoryPoolEntry:1.3.6.1.4.1.9.9.48.1.1.1

    here is an expression for mempool util

    (ciscoMemoryPoolUsed/(ciscoMemoryPoolFree+ciscoMemoryPoolUsed))*100


    OLD_CISCO_SYS_MIB.lsystem 1.3.6.1.4.1.9.9.48.1.1.1

    avgBusy1 1.3.6.1.4.1.9.2.1.57 Gauge read-only 1 minute exponentially-decayed moving average of the CPU busy percentage.

    avgBusy5 1.3.6.1.4.1.9.2.1.58 Gauge read-only 5 minute exponentially-decayed moving average of the CPU busy percentage.

     

    CISCO_SYSTEM_EXT_MIB.ciscoSystemInfoGroup

    cseSysCPUUtilization 1.3.6.1.4.1.9.9.305.1.1.1 Gauge32 read-only The average utilization of CPU on the active supervisor.

    cseSysMemoryUtilization 1.3.6.1.4.1.9.9.305.1.1.2 Gauge32 read-only The average utilization of memory on the active supervisor.

     

    CISCO_PROCESS_MIB.cpmCPUTotalEntry 1.3.6.1.4.1.9.9.109.1.1.1.1

    cpmCPUTotal5sec 1.3.6.1.4.1.9.9.109.1.1.1.1.3 Gauge32 read-only The overall CPU busy percentage in the last 5 second period. This object obsoletes the busyPer object from the OLD-CISCO-SYSTEM-MIB. This object is deprecated by cpmCPUTotal5secRev which has the changed range of value (0..100).

    cpmCPUTotal1min 1.3.6.1.4.1.9.9.109.1.1.1.1.4 Gauge32 read-only The overall CPU busy percentage in the last 1 minute period. This object obsoletes the avgBusy1 object from the OLD-CISCO-SYSTEM-MIB. This object is deprecated by cpmCPUTotal1minRev which has the changed range of value (0..100).

    cpmCPUTotal5min 1.3.6.1.4.1.9.9.109.1.1.1.1.5 Gauge32 read-only The overall CPU busy percentage in the last 5 minute period. This object deprecates the avgBusy5 object from the OLD-CISCO-SYSTEM-MIB. This object is deprecated by cpmCPUTotal5minRev which has the changed range of value (0..100).

    if (cpmCPUTotal5sec >= 0) then cpmCPUTotal5sec else cpmCPUTotal5secRev

    if (cpmCPUTotal1min >= 0) then cpmCPUTotal1min else cpmCPUTotal1minRev

    if (cpmCPUTotal5min >= 0) then cpmCPUTotal5min else cpmCPUTotal5minRev.

    These utilization OID's are vendor Specific ??

    For most devices data on interfaces comes from the RFC12!3_MIB

    That MIB is not vendor specific and so 'most devices' will respond. It is doubtful than a device from another manufacturer will respond to a CISCO MIB, so those would be vendor specific.

    Ok "*800" to get the result in "percent"..,

     

    In the Performanceview of Spectrum, often the Utilization is displayed as 0% because the precision of the calculation is done by "integer" without rest. I often have to switch to "Bits per Second" for these Performanceviews.

     

    Is it possible to use "Bits per Second"  as a default?

    This question should be posted as its own question rather than added to this one.
