Measuring Bandwidth Utilization - How To?

I am trying to find out how to measure the utilization on a 100mb serial link between two sites that are connected with 4500 routers and 3548 switches. I can't seem to find any good documentation on the site unless I'm searching incorrectly. Thanks.

A couple of great open source packages: Cricket or MRTG.

  • Measuring Bandwidth utilization on 3005 Concentrator

    I am looking for an easy way to measure utilization on a site to site vpn configured on a 3005 concentrator.
    Help?

    This can be done using MIBS. The two MIBS listed below give you the total number of octets sent out or received every 5 minutes. You can manually calculate the difference to figure out the utilization.
    .1.3.6.1.2.1.2.2.1.10
    ifInOctets OBJECT-TYPE
    -- FROM RFC1213-MIB
    SYNTAX Counter
    MAX-ACCESS read-only
    STATUS Mandatory
    DESCRIPTION "The total number of octets received on the
    interface, including framing characters."
    ::= { iso(1) org(3) dod(6) internet(1) mgmt(2) mib-2(1) interfaces(2) ifTable(2) ifEntry(1) 10 }
    .1.3.6.1.2.1.2.2.1.16
    ifOutOctets OBJECT-TYPE
    -- FROM RFC1213-MIB
    SYNTAX Counter
    MAX-ACCESS read-only
    STATUS Mandatory
    DESCRIPTION "The total number of octets transmitted out of the
    interface, including framing characters."
    ::= { iso(1) org(3) dod(6) internet(1) mgmt(2) mib-2(1) interfaces(2) ifTable(2) ifEntry(1) 16 }
    On tunnel interfaces, a different set of MIBS called "ALTIGA-MIB" need to be used. I feel you should also have a look at the document "How To Calculate Bandwidth Utilization Using SNMP".

  • Bandwidth utilization on topology diagram of LMS 4.2

    Hi,
      I am running LMS 4.2 , using that i am monitering some switches . I am using topology services also  . In that i am getting veiw of all connected devices with links. But bandwidth utilization is for those links are not showning in topology veiw .
    Is there any settings to be done in LMS 4.2.2 or any configuration changes to done on my switches ??  to find the traffic flow  bandwidth utiliztion.
    thanks ,
    pandian .

    Hi
    You have to enable RMON to measure bandwidth utilization.
    Take a look on the Monitoring and Troubleshooting With Cisco Prime LAN Management Solution 4.2 guide.
    Begining on the page 7-43 you can find the procedure.
    Hope you can set it

  • Bandwidth Utilization Avg or Max for capacity Planning best practice

    Hello All - This is a conceptual or Non-Cisco product question. Hope you can help me to get this best industry practice
    I am doing a Capacity planning for the WAN Link Bandwidth. To study the last month bandwidth utilization in the MRTG graph, i am seeing  two values
    Average
    Maximum.
    To measure how much bandwidth my remote location is using which value i have to use. Average or Max?
    Average is always low eg. 20% to 30%
    Maximum is continuous 100% for 3 hour in 3 different intervals in a day and become 60% in rest of the day
    What is the best practice followed in the networking industry to derive the upgrade size of the bandwidth by using the Utilization graph
    regards,
    SAIRAM

    Hello.
    It makes no sense to use average during whole day (or a month), as you do the capacity management to avoid business impact due to link utilization; and average does not help you to catch is the end-users experience any performance issues.
    Typically your capacity management algorithm/thresholds are dependent on traffic patterns. As theses are really different cases if you run SAP+VoIP vs. youtube+Outlook. If you have any business critical traffic, you need to deploy QoS (unless you are allowed to increase link bandwidth infinitely).
    So, I would recommend to use 95-percentile of maximum values on 5-15 minutes interval (your algorithm/thresholds will be really sensitive to pooling interval, so choose it carefully). After to collect baseline (for a month or so)  - go and ask users about their experience and try to correlate poor experience with traffic bursts. This would help you to define thresholds for link upgrade triggers.
    PS: proactive capacity management includes link planning for new sites and their impact on existing links (in HQ and other spoke).
    PS2: also I would recommend to separately track utilization during business hours (business traffic) and non-business (service or backup traffic).

  • Monitoring IPSec Tunnel Bandwidth Utilization

    We have a Cisco ASA 5520 supporting multiple VPNs - both remote-access  and Lan-to-Lan.  We would like to monitor the bandwidth utilization of the IPSec Lan-to-Lan tunnels. How can we do that?
    Thanks,
    Spr

    Hi Spr,
    Check out VPNTTG (VPN Tunnel Traffic Grapher) is a software for SNMP monitoring and measuring the traffic load for IPsec  (Site-to-Site, Remote Access) and SSL (With Client, Clientless) VPN  tunnels on a Cisco ASA. It allows the user to see traffic load on a VPN  tunnel over time in graphical form.
    Advantage of VPNTTG over other SNMP based monitoring software's is  following: Other (commonly used) software's are working with static OID  numbers, i.e. whenever tunnel disconnects and reconnects, it gets  assigned a new OID number. This means that the historical data, gathered  on the connection, is lost each time. However, VPNTTG works with VPN  peer's IP address and it stores for each VPN tunnel historical  monitoring data into the Database.
    For more information about VPNTTG please visit www.vpnttg.com

  • Top Wireless Client Bandwidth Utilization on WCS?

    Hi, there.
    Can I get the top wireless client bandwidth utilization info / report from WCS? I would like to know how high they can reach, and how many are those 'power users', so far I only find "Busiest Clients" but not quite certain sure about the meanings of the "threshold" and "utilization' besides, the minimum interval is 1 hour, which seems to long for me, I would like to have some data like MRTG which is in 5 minutes range, thanks.
    Leo

    Welcome to the discussions!
    There is no "relay" function in the "extend a wireless network" setup. Each AX that is set to extend communicates directly to the Time Capsule and not to another device that might be between it and the Time Capsule.
    If you need the "relay" function, your only real option to setup the WDS configuration to see if that might work better in your circumstance.
    When you say that you have one AX setup as a client only, this implies that it is set to "join a wireless network". In the "join" setting, the AX only receives a wireless signal, it does not "extend" or rebroadcast the wireless signal. You might want to try setting this device to "extend" to see if that might help the network performance.

  • Cisco Prime LMS 4.2- Bandwidth utilization

    Dear Experts,
    Is it possible to monitor port level bandwidth utilization like how much b/w currently using.?
    If we generate report, it gives only percentage, can we change it to bps or mbps.?.

    Hi Enea,
    The size of the DB is huge now, you can try to do a Force Purge
    go to Admin > Network > Purge Settings  >IPSLA data Purge Settings
    see if it helps.
    If not then the last resort is to Re-initialize the IPM database.
    here are the steps:
    1.stop the daemon manager
    2.
    /opt/CSCOpx/bin/dbRestoreOrig.pl dsn=ipm dmprefix=Ipm  (linux/solaris)
    NMSROOT\bin\perl.exe NMSROOT\bin\dbRestoreOrig.pl dsn=ipm dmprefix=Ipm    (windows)
    3.start the daemon manager
    Note: If you Re-initialize the database  then you need to create the collectors again .
    Thanks-

  • Measuring Resource Utilization

    Hi,
    I'm working on a project for my M.Sc. degree. I need to measure the utilization of the machines' resources. Is there any way to access such measurements from Java? Or is there a Java framework or open source project capable of this? I tried using NSClient4J but for some reason it seems inaccurate and does not capture changes quickly from Windows performance counters. I'm not bound to Windows by the way. Linux would be nice.
    Note, I don't won't to measure the application's performance on the JVM but the system's performance as a whole (CPU utilization, free memory, free disk space, etc.)
    Thanks in advance for any help of advice.

    Thanks for the reply Peter. But that is exactly my question (i.e. how can I measure these from Java). When I used NSClient4J, I measured the resource's utilization at regular intervals. But when I start some resource intensive application, this was not reflected appropriately in the measurements. That's I was asking if someone knows of another method/tool for doing this.

  • Ipqos to monitor bandwidth utilization in zones?

    I'd like to use IPQos and the extended accounting features in the global zone to monitor bandwidth utilization in my zones - ie, keep a simple count of amount of traffic each zone's IPs use.
    I can't quite figure out how to do it, though. The IPQos docs are extensive, but complex.
    Anyone got a simple 'howto' for it??

    not really using ipqos, but i have a dtrace script that tracks socket traffic per pid and uid, you can probably change it to meet your needs.

  • Capwap high bandwidth utilization

    Hello,
    I would like to know if this traffic is correct... (wan link - remote APs)
    minute:
    15 minutes:
    I think that something is wrong... there is a high bandwidth utilization.
    All APs are configured with h-reap and local switching.
    All traffic wan link - 15 minutes:
    thanks.

    Maybe this answer my question?
    Ongoing Exchanges
    Heartbeat
      The LWAPP architecture provides for a heartbeat timer that is
          accomplished by a series of Echo Requests and Echo
          Responses. An AP periodically sends Echo Requests in order to
          determine the state of the connection between the AP and the WLC. In response,
          the WLC sends the Echo Response in order to acknowledge the receipt of the Echo
          Request. The AP, then, resets the heartbeat timer to the
          EchoInterval. The LWAPP protocol specification draft contains
          a detailed description of these timers. The system heartbeat, coupled with
          fallback mechanism, is 4 packets every 30 seconds and is comprised of these
          packets:
    LWAPP ECHO_REQUEST from AP (78 bytes)
    LWAPP Echo-Response to AP (64 bytes)
    LWAPP PRIMARY_DISCOVERY_REQ from AP (93 bytes)
    LWAPP Primary Discovery-Response to AP (97 bytes)
    This exchange generates 33 bytes of traffic every 30 seconds.
    RRM Measurements
    There are two ongoing RRM exchanges. The first one, at every 60-second       interval, is the load and signal measurement and consists of 4 packets. This       exchange always adds up to 396 bytes:
    LWAPP RRM_DATA_REQ from AP (107 bytes)
    LWAPP Airewave-Director-Data Response to AP (64 bytes)
    LWAPP RRM_DATA_REQ from AP (161 bytes)
    LWAPP Airewave-Director-Data Response to AP (64 bytes)
    The second sequence of packets is the noise measurement that includes a       statistics information request and response sequence. It is done every 180       seconds. This short exchange of packets averages approximately 2,660 bytes and       typically lasts 0.01 seconds. It consists of these packets:
    LWAPP RRM_DATA_REQ from AP
    LWAPP Airewave-Director-Data Response to AP
    LWAPP RRM_DATA_REQ from AP
    LWAPP Airewave-Director-Data Response to AP
    LWAPP RRM_DATA_REQ from AP
    LWAPP Airewave-Director-Data Response to AP
    LWAPP RRM_DATA_REQ from AP
    LWAPP Airewave-Director-Data Response to AP
    LWAPP STATISTICS_INFO from AP
    LWAPP Statistics-Info Response to AP
    LWAPP RRM_DATA_REQ from AP
    LWAPP Airewave-Director-Data Response to AP
    LWAPP RRM_DATA_REQ from AP
    LWAPP Airewave-Director-Data Response to AP
    LWAPP RRM_DATA_REQ from AP 00:14:1b:59:41:80
    LWAPP Airewave-Director-Data Response to AP
    LWAPP RRM_DATA_REQ from AP
    LWAPP Airewave-Director-Data Response to AP
    LWAPP STATISTICS_INFO from AP
    LWAPP Statistics-Info Response to AP

  • Cat4K "Switch Bandwidth Utilization" SNMP OID

    Hello,
    I have several devices of the Cat4K family (C4948, C4900M, C4500X) for which "show environment" displays a "Switch Bandwidth Utilization" percentage.  Does anyone know how to get that value by SNMP?  I tried browsing the ciscoMgmt MIB from a 4500X but the closest thing I could find were OIDs for the status of the front-panel LED display for switch utilization (which the 4500X doesn't have)...
    Thank you.

    SNMP sure does that. Default OID should work fine. Community password is set to "public" by default.

  • Bandwidth utilization analyzer

    I have the complete lync setup with archiving server.  The reporting server works great.  The problem is I just got the resource kit for lync 2010 and it absolutely sucks at how to use the BANDWIDTH UTILIZATION ANALYZER TOOL.  The resource
    kit documentation is very crappy about how to use it. 
    What is the share or even type of file am i supposed to be looking for in order to make sure that when i use this tool, i will get the bandwidth usage for dates that i specify?  Is the folder that i connect to supposed to have log files, mdf, ldf, etc.?
    Any help is greatly appreciated.
    THanks again.

    Hi, Peace,
       There are three steps to using WanLinkLogCollector.exe:
    1.       
    Log the timeline   Provide the timeline that the report needs to be generated for
    2.       
    Specify the file directories   Provide file location information
    Server log files location: The folder location where Bandwidth policy server logs are stored. This is
    typically in <fileserver>\<choice of FE>\AppServerFiles\PDP.
    Temporary file storage location: The temporary file location where intermediate files are stored while
    the report is being generated.
    Ensure that sufficient file access to the server logs and the temporary file store folder is provided
    to the tool user.
    3.       
    Collect the logs and launch the report viewer   Execute the command to generate the report
