snmpcollector template editor error code MONS-025

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)
• CA Unified Infrastructure Management On-Premise (Nimsoft / UIM)
• CA Unified Infrastructure Management SaaS (Nimsoft / UIM)

Issue/Introduction

Open snmpcollector configuration using Admin console, then clicking Template editor yields a MONS-025 error but there are no errors in the ppm.log.

Environment

• DX UIM 23.4 CU6
• snmpcollector 6.03
• ppm

Cause

• When the CTD configuration JSON remains below approximately 8 MB, processing stays entirely in memory and succeeds.
• When the JSON exceeds the threshold, the probe attempts to write the data to disk.
• The temporary file creation fails due to the Windows service account resolution/permission issue

Resolution

Workaround
A permanent fix will be included in the next version of the snmpcollector probe. Until then, apply the following workaround:

1. Open Infrastructure Manager.
2. Double-click the snmpcollector probe to open its configuration.
3. Navigate to: Startup → Options
4. Click Edit Key.
5. In the Enter new value field, move to the end of the existing text.
6. Add a space and append the following JVM argument:     -Duser.name=SYSTEM
7. Click OK to save the changes.

This forces the JVM to use SYSTEM as the effective user context during temp file handling, preventing the Windows principal lookup failure when large CTD graph JSON files are written to disk.
