The result of this is just a list of lines with the \n or \r\n
stripped. Just to clarify too a line means a line in the file, not
a log record e.g. stack traces are generally composed of multiple
So this begs the question, will this work for what we want? What
concerns does anyone else have?
I have not yet submitted a PR yet as I wanted to get some
feedback before we bake it in.
I had posted this to another list, but this is a more appropriate place for it. I think there needs to be a general discussion around this as it's been mentioned, at least to me, a few times here and there and I know Heiko raised the issue some time a go now.
The original JIRA, WFLY-280, is to display the last 10 error messages only. To be honest I wouldn't find that very useful. To me if I'm looking for logs I want to see all logs, but that's not always so easy. Like the syslog-handler which doesn't log to a file so there is no way to read those messages back.
The current plan for the last 10 error messages is we store messages in a queue that can be accessed via an operation. This works fine until the error message you're interested in is 11 or you want to see warning messages.
Another option I had come up with is reading back the contents of the file, for example the server.log. This could be problematic too in that there is no way to filter information like only see error messages or only see warning messages. To solve this I have considered creating a JSON formatter so the results could be queried, but I don't think it should be a default which would mean it's not reliable for the console to assume it's getting back JSON.
I've also thought about, haven't tested this and it may not work at all, creating a handler that uses websockets to send messages. I'm not sure how well this would work and it's possible it may not even work for bootstrap logging.
With regards to audit logging, we're probably going to have to do something totally different from what we'll do in the logging subsystem since it doesn't use standard logging.
I guess the bottom line is what does the console want to see? Do you want to see all raw text log messages? Do you want all messages but in a format like JSON that you can query/filter? Do you really want only the last 10 error messages only? All or none of these might be possible, but I really need to understand the needs before I can explore more in depth what the best option would be.
