My Orion Website & Server is very slow / CPU & Memory Spike what should i check quickly ?

Version 62

    This article provides quick information about  your current environment and health check , Further it  will help you address the most common reasons of  performance issues on to your server without sending the diagnostics to SolarWinds support  .

    In this article you can also Audit your own environment quickly if its been setup as recommended by the Solarwinds MINIMUM requirements or according to the settings eliminating bottlenecks creating performance issues within the set environment .

    This article also help to save time to upload the diagnostics for Support where you have air gap between the server and you can check the basic health check on the actual server itself .

    There are lots of other benefits to check the environment health within the internal due to security procedure not allowing uploading the diagnostics for Solarwinds support .




    Your check list

    ✔Server Hardware

    ✔Total Elements (Nodes /Interfaces/ Volumes)  been polled per server

    ✔Check free disk space on the Orion Server and SQL server

    ✔Check Your Server Polling  Rate

    ✔SQL Server / Orion DB Size / Settings / Options

    ✔Check SQL Server Disk Performance

    ✔Orion Antivirus directory exclusion

    ✔Webpages Customization


    Lets Go!

    Collect System diagnostics as below.

    Navigate to Start -> SolarWinds Orion -> Documentation and Support

    Launch the gray icon for Orion Diagnostics.> Click "Start"

    This program will generate a .zip file as output.

    ( Unzip in a folder ) Right Click >  Select Extract Here .


    Server Hardware

    Lets check your System Hardware first if this even near to the Solarwinds MINIM recommended.

    Go to the SystemInformation folder > Open the SystemInfo.txt file



    You will be able to find the System hardware specification  below is an example where system is only assigned with 2 Physical CPU Sockets /

    below is an example where the system is only assigned two CPU PHYSICAL SOCKETS which is below Solarwinds MINIMUM recommendation .

    You must have to have MINIMUM 4 PHYSICAL CPU SOCKETS here .



    System Type:               x64-based PC

    Processor(s):              2 Processor(s) Installed.

                               [01]: Intel64 Family 6 Model 45 Stepping 7 GenuineIntel ~1600 Mhz

                               [02]: Intel64 Family 6 Model 45 Stepping 7 GenuineIntel ~1400 Mhz


                              Total Physical Memory:     49.082 MB

                              Available Physical Memory: 39.408 MB

                              Virtual Memory: Max Size:  56.250 MB

                              Virtual Memory: Available: 45.376 MB

                              Virtual Memory: In Use:    10.874 MB


    Now open the SysInfo.csv file and check the further current CPU load on the System and CPU GHz level .

    Below in an example where the CPU load in around 70% on the current system due to two main reasons .





    Windows Server 2012 R2 (Microsoft Windows NT 6.2.9200.0)


    Intel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz


    70 %


    49152 MB


    39802 MB


    45843 MB


    7109 MB


    xxxx Standard Time (UTC+01:00:00)


    Low Physical Sockets assigned

    Low CPU power less then 3.0 GHz


    You should be able to see MINIMUM 4 Physical Processors  Sockets as below .


    Strongly recommend :  NOT to use lower then 3.0 GHz processor you will never get the performance what you are looking for even the Host and Guest wont show the CPU is busy .

    Most likely you will see CPU spikes / Orion Services consuming High CPU and Memory . Once you will move the same VM to higher then 3.0 GHz process all the above symptoms will be resolved.

    With lower then 3.0 GHz processor there might be other issues such as SQL Server TCP connections TimeOut Errors and High amount of data  stored under MSMQ on the system .





    Make sure you have MINIMUM 3. Ghz host with Hyperthreading Active it will improve the Guest performance significantly and you will have full performance out of Solarwinds application


    This is how you setup your VM in ESX




    Here is an Example when you assign the numbers of CPU SOCKETS to the VM



    System Model:              VMware Virtual Platform

    System Type:               x64-based PC

    Processor(s):              4 Processor(s) Installed.

                               [01]: Intel64 Family 6 Model 15 Stepping 1 GenuineIntel ~3493 Mhz

                               [02]: Intel64 Family 6 Model 15 Stepping 1 GenuineIntel ~3493 Mhz

                               [03]: Intel64 Family 6 Model 15 Stepping 1 GenuineIntel ~3493 Mhz

                               [04]: Intel64 Family 6 Model 15 Stepping 1 GenuineIntel ~3493 Mhz

    BIOS Version:              Phoenix Technologies LTD 6.00, 4/14/2014



    Further check how much memory is assigned and available for the system and check the TaskManager which application is consuming high memory .


    In above case the System Hardware is not even near to the recommended SolarWinds production deployment therefor the CPU load will remain high therefor System resources.


    The following table lists minimum hardware requirements and recommendations for your SolarWinds Orion server.

    Installing multiple SolarWinds Orion Platform products on the same computer may change the requirements.

    Hardware requirements are listed by SolarWinds NPM license level.

    NPM hardware requirements

    These minimum requirements are for the Orion Platform. Products that run on the Orion Platform may have different requirements, such as different OS or memory requirements.

    Consult your product-specific documentation for the exact requirements.


    SL100, SL250, SL500



    CPU speed

    Quad core processor, 2.5 GHz or better

    Quad core processor, 2.5 GHz or better

    Quad core processor, 3.0 GHz or better


    For more details see below guide

    NPM 12.0 system requirements - SolarWinds Worldwide, LLC. Help and Support

    Check free disk space on the Orion Sever and SQL Server

    Make sure you have Good free space available on the Orion Server disks C Drive and installed Directory .

    Make sure you have Good free space available on the SQL Server where the actual DB is stored.


    Total Elements (Nodes /Interfaces/ Volumes)  been polled per server

    Go to folder "DB" > Open file "AllEngines.csv"


    Check how many Elements you are polling per server

















    With only SolarWinds SLX license you can montior up to 12000 Elements and beyond this you will need an Additional Polling Engine to monitor.


    More Details see the Server Sizing guide .


    Server Sizing recommendations

    Use additional polling engines for 12,000 or more monitored elements

    If you plan to monitor 12,000 or more elements, SolarWinds recommends that you install additional polling engines on separate servers to help distribute the work load.

    I would also strongly advise you to check the blog post for any other questions if you are polling beyond 12000 Elements with single SLX Server.

    Boost your server polling capacity with Stackable Poller license


    Check your Server Polling Rate


    Go to Settings > Polling Engines .

    Check if any of the Polling Rate is increased ?

    Make sure none of the Polling Rate exceeded above 100%


    POLLING RATE2% of its maximum rate.
    ROUTING POLLING RATE0% of its maximum rate.
    HARDWARE HEALTH POLLING RATE0% of its maximum rate.
    F5 POLLING RATE0% of its maximum rate.
    WIRELESS HEAT MAP POLLING RATE0% of its maximum rate.
    WIRELESS POLLING RATE0% of its maximum rate.
    UNDP POLLING RATE0% of its maximum rate.
    SAM APPLICATION POLLING RATE                       170% of its maximum rate.                  


    If you have any polling rate increased above the 100% you will notice high CPU / Memory Utilization on the System which could effect the System and application Performance .


    Orion DB Size and settings

    Go to the DBInfo Folder > Open DatabaseInfo.csv file

    Check the Database Recovery Mode

    Check the Total Database Size


    Default DB Recovery should be SIMPLE (Strongly recommended)
