Ok so I’ve been having a problem with logging for a while now. I use a centralized logging platform (Seq) to try and aggregate the logs of the containers I run but most of the log messages come through as errors. This is because the containers would stream their output to stderr and even though it’s formatted it comes as one big error message.

Example:

[2025-01-06 18:17:23] INFO Registering with TVA backend, encode Job status: available

That’s all one big error message I receive even though it’s an INFO message. And every container is different. Their error message is formatted differently, some goes to stdout instead of stderr, some actually work.

Is there a piece of software that I can run that will intercept these messages and convert them to GELF?

Thanks

    Seq is expecting structured logs which yours aren’t. So you want to either convert your app’s logs into a structured format (which is generally hard for a random third-party application) or use a log collector that’s fine with non-structured logs (e.g. Loki+grafana don’t care about the shape is your logs and you can format the output while querying).
