The SolarWinds Recommendations folder is filling up with log files

Table of contents

Updated August 4th, 2017


The Recommendations folder capacity in ProgramData is being consumed by the Diags JobsResultsOutput subfolder. There is an increase in space by design in huge environments and the details of every computation are logged which causes the C: drive to fill up. 



NPM 12.0.1

NPM 12.1


This is caused by the SolarWinds Recommendation Service storing logs and its retention settings.


The Recommendations service is a new feature added in NPM 12.0 which inspects polled environments and recommends actions to resolve issues and improve overall state.


Issues associated with the Recommendations service usually occur in larger Orion Platform environments. 
If the Diags subfolder are larger than usual or the Solarwinds Log folder is filling up on C: drive, perform the following procedure(s): 

First you should clean out the old log files.

  • Delete log files in C:\ProgramData\Solarwinds\Logs\Recommendations\.
    • This is a stop gap measure and should be performed to stop this from recurring.
    • It is not necessary to stop the services when deleting these files.


Then apply one of these various solutions:

  1. Uninstall Recommendation Engines from Start -> Control Panel -> Programs & Features. (Requires CW to be run)
  2. Open Services.msc and set the "Solarwinds Recommendation" Service to disabled and stop the Service.
  3. You can also edit Recommendations Settings and disable it in LogAdjustor as shown below.
    1. Decrease the amount of days/hours by editing the following settings in Centralised Settings Page.
      • The log files being stored on the disk can be configured via Centralized settings.
        • The Settings editor pages are hidden and can only be accessed through the following URL:
        • {OrionWebsite}/Orion/Admin/AdvancedConfiguration/Global.aspx 
      • For NPM 12.0.x and earlier:
        • OldJobsLogDeletionDaysRealtime
        • OldJobsLogDeletionDaysRegular
      • For NPM 12.1 and later, setting the below to 1
        • OldJobsLogDeletionHoursRealtime 
        • OldJobsLogDeletionHoursRegular
        • and OldJobsLogDeletionCron to 0 * * * *
  4. Turn off logging for the Recommendations engine using Log Adjuster: 
    1. Go to SolarWinds Orion > Documentation and Support > Log Adjuster. 
    2. Change the Recommendations Jobs value from DEBUG to OFF\INFO, and then click Apply.
  5. Upgrade to the latest version of NPM as this has improvements to this service.
