Oh this looks promising.

Well I can get the logs in Seq. I don’t know how to process the logs that come in so they are at the right level, timestamp, message, etc. Guess I look into it tomorrow…

Yeah but the thing is I have it set up to read the logs being sent out from my Docker containers. Even though I’ve set the containers to output using the GELF driver they don’t really do that. The log messages my container send are not in GELF format so I have to find a way to fix that.

I’m not clear in the post I guess so I’ll try to be more clear here.

• I’m using Seq for my centralized logging.
• The logs I get from most of my containers are not in GELF format. I cannot change that unless I change how logging works in all the programs I use. So I’ll need to edit every source code and compile or ask each project to update their logging and output to GELF.
• They are all shown as errors or info. It depends on the container because some send their logging info to stderr and some to stdout.
• I’m looking for something that can intercept those logs from my other containers, format them to GELF, and send the formatted logs to Seq.

I’ve done that. I don’t have a formatting issue. The containers I’m trying to get logs from have a formatting issue. They don’t stream their logs in GELF. I am getting the logs but I can’t change the formatting that they send me unless I mess with the code itself.
