    Hi
    How i know what monitors do i have to add to watch in the LR controller?

    I have the project plan which says " CPU", "Memory" and "JVM"?

    How can i get more details on this?
    Do i need to know the complete design of the project?
    This project is WebServices testing.

    Any input is welcome.

    Thanks

    Re: Monitors to watch?

    How can i get more details on this?

    You can do some research on the web, or you can look at perfmon help (if your app using windows).
    Also, look at JVM specs or tuning papers. You'll need to understand jvm heap, gc, etc...

    Do i need to know the complete design of the project?
    Knowing overall architecture is very helpful.

    CPU, memory, JVM.

    Sounds pretty straight forward to me. If they want you to watch those things, then yes, add those monitors to your load test.

    Personally, I prefer to track other things like memory utilization, etc. But if you have an actual project plan and that's all they want info on, you've got it good!

    I agree with Ted, knowing the architecture is very helpful, especially if people start asking you questions like "WHY is this happening, or WHAT caused this". You can't answer those questions without knowing the app.

    Re: Monitors to watch?

    LR Controller provides graphs for Windows Resources, SNMP, UNIX resources. I think we need additional licenses for these to start showing real-time data.

    But, to crosscheck if you are getting expected information from LR or not, you need to know project design completely.

    Re: Monitors to watch?

    Sounds like your project plan does not have Clear Goals. A common mistake is to say oh we will just watch CPU, and memory, but for what? What is the goal of the test? there are so many more things to look at. here is a common set of metric I tend to use. Helps with memory leaks, page file settings, Disk IO issues, Network bottlenecks,

    AIX Metrics
    % CPU Utilization
    % Memory Utilization
    I/O- %Disk busy
    I/O- Transaction Rate/Second
    % Swapping

    Network Metrics
    Packages/Second
    Packages errors (in/out)
    NW %Utilization

    WAS Metrics
    Active Sessions
    Thread Pools
    %Memory Utilization
    GC activities

    Web Metrics
    Transaction Summary
    Transaction Per/Second
    Throughput
    Number of Virtual users
    HTTP Response times
    Page Response times

    DB2 Metrics
    DB Connections
    Physical reads/writes
    Logical reads/writes
    Locks (deadlocks/lock_timeouts)
    Hit ratios (Buffers/Package
    Sorts (sorts/sort_overflows)

    This is a Short list, but should give you an Idea.

    Re: Monitors to watch?

    Hi,

    If you are monitoring Windows Resources, you can watch the following counters to get information relating to CPU and Memory

    Processor(_Total)\% Processor Time
    Processor(_Total)\% Privileged Time
    Processor(_Total)\% User Time
    Processor(_Total)\Interrupts/sec
    Process(instance)\% Processor Time
    Process(instance)\Working Set
    Physical Disk (instance)\Disk Transfers/sec
    System\Processor Queue Length
    System\Context Switches/sec
    Memory\Pages/sec
    Memory\Available Bytes
    Memory\Cache Bytes
    Memory\Transition Faults/sec

    I've written an article in my blog which explains the counter and how they can be useful (link below). Please feel free to explore.

    Re: Monitors to watch?

    thanks for all your response.
    I have to monitor Unix resources and apache. I have licence for both.
    Let me explore more.
