Textfile: Duplicate filename detected in 0.27.0

[davideverall]

Current Behavior

After upgrading from 0.25.x or 0.26.0 the textfile collector is reporting duplicate filename where there is no duplicate.

Error message:

ts=2024-08-13T08:52:33.522Z caller=textfile.go:325 level=error collector=textfile msg="Duplicate filename detected: \"C:\\\\Program Files\\\\windows_exporter\\\\textfile_inputs\\\\test_textfile_metric.prom\". Skip File."

Verified on:

• Windows Server 2019 Standard
• windows_exporter v0.27.0

Expected Behavior

There should be no error as there is no duplicate filename.

Steps To Reproduce

1. Install windows_exporter version 0.27.0 with the textfile collector enabled
2. Create a textfile in `C:\Program Files\windows_exporter\textfile_inputs` with .prom file extension
3. Check application log for errors

Environment

• windows_exporter Version: 0.27.0
• Windows Server Version: 2019 Standard

windows_exporter logs
