Measuring Network Traffic

Hi friends,
What's the difference between measuring by(bytes or packets)?

No, you have the client, there i need the total traffic caused by that client. That must be send to the server together with the windows logon name.
On the server, he reads the information that he gets from the client (like every 5 minutes or something) and that he puts in a hashtable.
When the client logs out, there must be a final update to the server with the latest stats and an extra status parameter that says the user is going offline. Then the server updates his hashtable first, reads the final data for that user, puts it in the database and then delete that user (session) out his hastable.
So in fact, i just need to know how i can get access to the traffic on the client side.

  • Measure network traffic

    I want to measure the whole internet traffic comming in or out of my eri/hme etc. in kb/s|mb/s. As I don't want to install any tools like net-snmp, mrtg, or other net traffic counter, I'm wondering if there is a basic unix command.
    I appreciate any help
    Cheers, Martin

    Hi,
    To complement my answer you may also want to try out
    kstat -n [ ip | icmp | stcp |  tcp | udp]
    and/or
    netstat -s
    Hope this helps,

    PS: Note that Java DMK 5.1 (http://java.sun.com/products/jdmk/index.jsp)
    has an example (called SolarisKstat)
    which works on solaris - and will generate an MBean which will be
    able to get at the data exported by a kstat module through JNI.
    So in principle you could also use Java SE 5.0, JMX, and JDMK
    to export your kstat data to a remote manager.
    The example is a little raw, and I am not completely sure on which
    solaris version it was last tested....

  • MDNSResponder problem / network traffic reduction measures in effect

    [Part I in a series of "Why Does My Machine Randomly Shut Down And Related Oddities" :-D ]
    Below you can see a bunch of log output which seems to show a network problem. My connection is not too fast, which I've blamed on my low tier of U-Verse, but this makes me wonder. And it seems to occur each wakeup.
    "network traffic reduction measures in effect" I've found mentioned as an AirPort problem.
    BUT, my AirPort is OFF.
    (Plus, why is it changing the host name and then back again?)

    Is that an actual dump from your logs? If so, I find it strange - not least because the timestamps are not consecutive. That certainly makes it harder to trace what's going on.
    Deciphering it as best I can, I'd say you have a flaky network. This could be due to cabling or some process on the machine that's interrupting sleep - I find it strange that many of the mDNSResponder messages are timestamped while the machine is asleep. That could be related to the various wake-on-LAN options - are they enabled in System Preferences -> Energy Saver?

  • How to measure network logon traffic by clients

    Hi,
    We want to understand what network logon traffic is generated by various clients on a physical network.  Is there a way to measure this traffic which includes items like group memberships, GPOS, logon scripts, offline folders, etc.  We have
    a large international AD deployment and understanding network logon traffic would be beneficial.
    Thanks for your help! SdeDot

    Hi,
    For that you have to run Network monitor.

  • Measure network bandwidth of SQL Server

    Hi everyone,
    I'm using SQL Server 2k5. Now I get a request to measure the network traffic of a certain DB. For example, how many GB data are in and out from a DB in 1 hours or longer. Is it possible to use SQL profiler or some other tools to grab the information? Thank
    you very much for your time and efforts.
    regards,
    Oliver

    In addition to Shanky's response, 
    you can use tools like the Wireshark, in order to monitor it. You can use filter like:
    filter capture on port 1433:
    http://en.wikipedia.org/wiki/Wireshark
    * Wireshark is perfect to capture the traffic, but it will not tie specific packets to specific queries. for this you should use the combination of profiler as well.
    ** This is not a recommendation to use specific application or to install anything on production!
    If you want to monitor network traffic between web application hosted in IIS and SQL Server, both of which are running on the same server, then the faster and easier way is monitoring the IIS (there is build-in log file that you can use), or from the application
    itself. but those options have some limitations. please check this link: http://dba.stackexchange.com/questions/45846/how-do-i-monitor-bandwidth-used-by-sql-server-on-port-1433

  • Network traffic of an End-User Experience Monitoring (EEM) Robot

    Dear Experts,
    our company is currently using three EEM-Robots in different countries.
    After one month we noticed, that the network traffic of the robots is quite high (one robot used about 8 GB in one month).
    So I checked the configuration of the robots:
    Every Robot runs about five scripts, which are executed every ten minutes. Therefore every robot exectues 30 scripts in one hour.
    There are four SAPGUI Scripts and one http-script. Every Script (besides the http-Script) is collecting the system data (bold letters in the monitoring) and the trace level low (parameter trace.e2etracelevel = 0).
    So I start measuring the network traffic. I observed the connection with Wireshark:
    The robot uses in average 4000 Byte per second, which equates to 9,66 GByte for one month.
    After stopping every script and rebooting the robot, I measured the traffic again.
    The robot uses without executing a script in average 820 Byte per second, which equates to 2 GByte for one month.
    Are there some settings I overlooked, possibilities to decrease the network traffic? 
    Is that size of network traffic within the normal range?
    Regards
    Alex

  • I need a clarification : Can I use EJBs instead of helper classes for better performance and less network traffic?

    My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
    I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
    Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
    Please suggest me which method (is Helper classes or Using EJBs) is perferable
    1) to get better performance and.
    2) for less network traffic
    3) for better container resource utilization
    I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
    Please give detailed explanation.
    thank you,
    sudheer

    <i>Please suggest me which method (is Helper classes or Using EJBs) is perferable :
    1) to get better performance</i>
    EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
    <i>2) for less network traffic</i>
    There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
    <i>3) for better container resource utilization</i>
    Again, the EJB version will consume a lot more container resources.

  • Share network traffic between 2 parallel wireless bridges - What kit?

    Dear All,
    I'm a technology professional, but mainly in electronic design rather than high end networking. Hence my request for your advice.
    I wish to specify some items of kit that I can ask a networking professional to fit and configure to solve my particular application.
    I would like to use (and already have in place) two parallel wireless bridges between 2 buildings. One is on 2.4GHz and the other is on 5GHz. In my simple testing so far (of each link in turn), they both work brilliantly. So far, these are in place just for test purposes, but soon I will be required to make the system "live".
    The reason I'm doing this is to split network traffic over both links (to possibly get enhanced bandwidth) but to mainly build in redundancy should one link fail.
    What kit is required to do this (apart from the 4 access points configured as bridges)?
    I imagine I may need a load balancing device(s) or possibly something more suitable for this task.
    I'd like the solution to be very transparent to the rest of the system, I'd like it to "look" like it's a simple wireless bridge (but really it's a highly robust dual bridge). I hope my waffle makes sense.
    Any thoughts?
    Best regards,
    L.O.

    You can certainly copy the addresses from one machine to the other - the contact files are held in user/Library/Application Support/AddressBook. Copy all files into the same respective location on the other machine (they will overwrite any existing contacts).
    If you want the address books kept in sync, take a look at SyncTogether or SeeCard Rendezvous.

  • Server admin not showing network traffic graph

    This topic was posted a while ago with no solution, and it has been [archived|http://discussions.apple.com/thread.jspa?messageID=6953359]. I have just experienced the same problem with Leopard Server Admin (SA). It seems to be a problem on the server, not in the client admin, since it occurs both when I use SA on the server itself and a client, and deleting client prefs. has not helped. I'm presuming that there is a corrupted database or prefs. file for this graph.
    All the other SA graphs show just fine. Fixing permissions has not helped, either.
    Anyone have any idea where to look on the server? Thanks.
    Message was edited by: Trevor Jacques

    I'm pretty sure I have since I have a few Mac Mini's on the network with their home directory residing on the server and my Windows users are sharing a few daily use files on the server including a MYOB data file, also our intranet web site is hosting on the same server, not to mention I have 3 print queues there and all the outgoing mails from both of our all-in-one scan to email machines are using the same server. All of these services and users are using their computer as if nothing is wrong, so I have to assume that there is network traffic unless server admin interprets the term "network traffic" differently.

  • How do I time out my thread if there is no network traffic

    How do I time out my thread if there is no network traffic for a given time? I have the following code listening for data:
    StringBuffer requestLine = new StringBuffer();
    int c;
    while(true) {
        c = in.read();
        if(c == '\r' || c == '\n') {//Not sure here???
            break;
        requestLine.append((char)c);
    }But how do I time this out if there has been no traffic for lets say 5 minutes?

    Have you redefined 'in'?
    If it's a raw socket connection, you can use the Socket.setSoTimeout method before you open the connection to specify how long it should hold it open if there is no data available.

  • Unknown network traffic / router traffic monitoring

    So I got a new PC with windows 7 on it, and I installed this gadget that monitors network traffic, and it shows a lot of traffic that my local PC isn't showing, so I am thinking there is something running on the LAN that I can't see. I was looking to find a live, better program to monitor the actiontec router, for traffic. anyone know of anything that can maybe show me who is using all the bandwidth on my network?
    i have found software for Linksys, but nothing for the Actiontec.
    Thanks,

    Fios in Florida
    Solved!
    Go to Solution.

    Keep in mind that when looking at Wireshark (sniffer) software there are different types of traffic:
    Unicast
    Broadcast
    Multicast
    Unicast is traffic between two devices.  You will see the traffic between the PC with wireshark and another device on your local network such as a printer, another PC or the Router.  You should not see traffic between another PC and the Internet for example.  Using a phone as an example some calls you and the conversation is between you and the person on the other end of the phone.  This is unicast traffic.  Using defaults of the actiontec, IP address seen will be 192.168.1.1 for the router and 192.168.1.2-99 for devices on your network.  If you have the TV service, 192.168.1.100-1xx is used for the cable boxes.
    Broadcast traffic is traffic sent to all devices.  Its not directed toward a particular PC but rather usually looking for information.  In a sniffer trace you will see broadcast traffic. Going back to the phone example, someone makes an announcement on an overhead intercom system that is broadcast traffic.  Broadcast traffic will be seen as 192.168.255.255
    Multicast traffic is traffic from one device for many devices.  Usually used in video feeds.   Using the phone system as an example someone wishes to tell a group of people something so instead of calling each person up and telling them each person who wants the information joins a conference bridge.  Anyone is allowed to listen but only those that wish to get the information receive it.  Generally how multicast works.  Multicast traffic will be seen as IP address 224.x.x.x or something of the sorts where the address will be 2xx.x.x.x.  
    I hope this makes sense.  Probably more information than you needed but at least it will help you understand what wireshark is telling you.

  • SAP DMS - SAP ECC network traffic

    Hi all,
    I have the following situation:
    The SAP ECC servers are hosted outside my company and we are planning to install a SAP DMS server.
    We have 2 options: host the SAP DMS outside or install SAP DMS in our datacenter.
    When the SAP user attaches or reads a file to/from SAP DMS, how is the network traffic ?
    Is there any traffic fom SAP ECC to SAP DMS or the file goes to/from DMS from/to end-user ?
    How SAP DMS impacts my WAN ?
    Best Regards,
    Leonardo.

    Leonardo,  I have done some research /  trouble shooting and architectural changes to raise the upload / download speeds, there are several dependencies like Network, Application, hardware etc but to your question:
    First of all, DMS is a core functionality of ECC and utilizes both ECC for execution and Content Servers (recommended for Obvious performance reasons) for Data Storage. For your case I recommend that you host Content Server at the Data Center (assuming you have no other option) and have a Cache Server installed Onsite. (This requires minimal maintenance). When the user uploads a file the traffic is high as the entire File needs to be transferred to the data center, on the other hand Cache server (if installed onsite) considerably reduces the retrieval time.
    Again having said above there are several other parameters that could affect your upload / download speeds.
    Hope you'll find this useful, let me know if you have further questions.
    regards

  • Curious about App-V 4.6 RO Cache Network Traffic

    Our environment is Server 4.5 SP2, and Client 4.6 SP3. We utilize RO cache on DFS network storage, and our clients are VDI VM's.
    We recently ran into an issue when we recycled a large pool of VM's where the CPU/Network Utilization was maxed on our cache file server. Upon further investigation there appears to be about 550MB of traffic between each VM and the Cache file itself when
    the VM boots (no users logged in). Can someone explain to me what this traffic could be?

    In RO cache mode (ReadOnlyFSD], *nothing* should get streamed down to the client at all.
    where does the amount of data show up - any specific files/folders, or monitored network traffic between the client and the DFS share?
    is there anything in the App-V log file?
    Did you initiate a server publishing refresh with a user that has access to all applications before you sealed the VDI Master image?

    Camelot,
    Thanks again for your response!

    Safari can't connect to the server "localhost".
    The only thing I can think of off-hand that would cause this is if mod_status was disabled (which you might have done thinking you didn't need it). It would be a good idea to re-enable this, even if only short-term, to get an idea of what's going on.
    mod_status is not listed in Web > Modules
    Not sure if it will help significantly but I did enable the query cache for MySQL.
    The query cache will generally help reduce load on the database server, but only if there's sufficient RAM on the server to cache the queries and results. The real question is how mush RAM is your system using? If it's out of memory then enabling the query cache can be detrimental.
    For that matter, do your sites seem slow? Is your only concern the relatively high CPU load? or are pages loading slowly, too?
    The pages are taking exceptionally long to load.
    The 1.7 Gb Ram...Yes, it's a config of 512-512-512-256.
    Swapping that 256MB for a 512MB seems like a no-brainer, no matter what else you do. It'll cost you $20 from OWC.
    You're right...no brainer. Will do
    Was wondering if a permissions issue could create the problems I'm having with Apache?
    Unlikely. If apache didn't have permission to serve a file it would throw an error page back pretty quickly. I can't see this is the cause, but a quick look at apache's error log will tell you if there are any permission issues.
    The site was running well this morning but as bloggers logged into Wordpress and general traffic picked up, the CPU load ramped up to 100% and pages are now loading very slowly.

  • Excess network traffic - what's causing it?

    I recently purchased a Mac Mini Server and today I reinstalled my server software to try to fix some permission problems.
    Anyway, I must have turned something on or off incorrectly because my network traffic suddenly started going through the roof for about six hours until the monthly cap with my ISP was exceeded and they slowed my connection.
    Any ideas what could be causing this excessive traffic?
    I am confident that it wasn't the result of any large downloads etc (18GB in 6 hrs!) and I can't help but feel it was just an incorrect setup somewhere.
    As you can probably tell, I'm all new to this server business so please excuse my naivety.
    A screen shot of my network activity graph is at http://idisk.mac.com/mtilley/Public/temp/Activity.png
    I turned the web service off before taking the screen shot but that was about 9:00 pm.

    That could well be it.
    Just checked the size of the downloads - 17.64 GB.
    Thanks cpragman for your much appreciated help.
