Unable to retrieve URL using PDF type


This article addresses the issue where you are unable to retrieve the URL using PDF type.


All NPM versions


  1. Replicate the issue and check the most recent ActionsExecution.log file from C:\ProgramData\Solarwinds\Logs\Orion:

    2016-04-27 13:50:11,275 [87] WARN  SolarWinds.Orion.Core.Actions.Utility.WebPageFetcher - We failed just on 0 attempt to export into pdf. We will try to export again.

For NPM 11.x and earlier

  1. Go to C:\Program Files (x86)\SolarWinds\Orion\SolarWinds.Orion.Core.BusinessLayer.dll.config, copy and paste the file to the desktop so that you have a backup of the original file and can roll back the change if necessary.
  2. Take note of the default values:
    <add key="NavigationTimeout" value="00:08:00" />
    <add key="ConversionDelay" value="00:00:10" />
    <add key="MaxConcurrentTaskCount" value="30" />
    <add key="ConversionRetries" value="2" />

       Change to:
    <add key="NavigationTimeout" value="00:60:00" />
    <add key="ConversionDelay" value="00:01:00" />
    <add key="MaxConcurrentTaskCount" value="50" />
    <add key="ConversionRetries" value="5" />

  3. Restart SolarWinds services after the change.


For NPM 12.x

  1. Open the Orion Advanced Configuration by changing the Web page url:
  2. When this page opens, scroll down to the ExportToPDFCmd.ExportToPDFSettings :-
  3. If the document that is being converted is very large, it may be necessary to increase the Conversion or Navigation timeout.
  4. Save the changes, restart services if prompted on the page, and test the export function again.
