File invalid on custom log source

PauAL — Fri, 23 May 2025 13:20:06 GMT

Hi,

I have added a custom log source including a text file. The file has extension ".log" and its content is a JSON per line. If I check in Logs tab inside Process group page I can see the file below "Container Output" logs, so the file is detected as a log file. But it is shown with grey text as if it was disabled and with "(File invalid)" suffix. I have tried to change the content to just a readable text line with same result.

What am I missing? Do I need to configure anything else in Dynatrace? Are these kinds of logs not supported?

Thanks!

Hi,

You can check OneAgent log data formats and Security rules.

Best regards

Hi @PauAL

Do you have a log ingest rule enabled that covers this log source? https://docs.dynatrace.com/docs/analyze-explore-automate/logs/lma-log-ingestion/lma-log-ingestion-via-oa/lma-log-storage-configuration
