This can be done but it is not recommended by SolarWinds. This figure of 2000 max is hard coded into the web page for performance reasons. The editing of this page to a figure above 2000 can result in the page giving you timeout errors and also can result in the page crashing frequently. You must remember that every time you apply the filter you are sending a huge long running query to your database to pull the required Syslog information from the Orion Database.
Instead of doing this, we recommend that you create a report using the web based reporting to configure a report based on the Syslog table - Create, assign and edit report schedules for NPM.


NPM 10.4 and later



  1. Remote access to your Orion Server.
  2. Go to C:\inetpub\SolarWinds\Orion\NetPerfMon and create a backup of the Syslog.aspx.cs and Syslog.aspx files in your desktop.
  3.  In the SysLog.aspx.cs file,at approximately line 170 there is:
    _maxRecords = Math.Min(Math.Max(_maxRecords, 0), 2000);
    In the SyLog.aspx file, at line 108 there is:
    MinValue="0" MaxValue="2000" ValidatorText="<img src='/Orion/images/Small-Down.gif' title='Value must be a valid integer from 0 to 2000'/>" />
  4. Change the values (2000) and then restart all SolarWinds services (open a CMD and type IISreset).

Note: If you run a repair or install a hotfix or run the Configuration Wizard, then you will have to do the above steps again as the website will recompile and return to default settings.
