Overview

In Self-Hosted Platform 2025.4, Core.Pollers.Jobs log files may continue to accumulate under the SolarWinds installation directory because the cleanup pattern for these log files is missing from the log file pattern list in Orion.xml.

Observed behavior may include:

  • Increasing disk space consumption on the SolarWinds server

  • Growth of Core.Pollers.Jobs_* log files over time

  • Log cleanup not removing old Core.Pollers.Jobs files as expected.

Cause

The issue occurs because the Core.Pollers.Jobs_* log file pattern is not included in the <LogFilesPatterns> section of the following file:

<InstallationDirectory>\SolarWinds\Orion\Modules\Orion.xml

Because the pattern is missing, the platform does not include these log files in its cleanup process.

Resolution

Resolution:

 

The issue is fixed in Self-Hosted Platform version 2026.1 and later. Upgrade to version 2026.1 or a later version to permanently resolve the issue.

Workaround:

If an upgrade is not immediately possible, use the following workaround.

  1. Go to the following path:

<InstallationDirectory>\SolarWinds\Orion\Modules\Orion.xml

  1. Edit the file.

    Note: Make a backup copy of the file before making any changes.

  2. Look for the following section:

<LogFilesPatterns>
  <LogFilesPattern>Core.Collector.Jobs_*</LogFilesPattern>
  <LogFilesPattern>Collector.Jobs_*</LogFilesPattern>
  <LogFilesPattern>Core.Jobs*</LogFilesPattern>
</LogFilesPatterns>

       4. Change it to the following:

<LogFilesPatterns>
  <LogFilesPattern>Core.Collector.Jobs_*</LogFilesPattern>
  <LogFilesPattern>Collector.Jobs_*</LogFilesPattern>
  <LogFilesPattern>Core.Jobs*</LogFilesPattern>
  <LogFilesPattern>Core.Pollers.Jobs_*</LogFilesPattern>
</LogFilesPatterns>

      5. Restart all SolarWinds services.
