log4net multiline support

g00py's profile on WallpaperFusion.com
Haven't been able to find info on setting up multi-line log file reading, so I could merge mutliple log4net files into a single pane and review the history. Any tips or plans for "regex" or other type of parsing, and saving this configuration to open other matching files with?

Are you wanting to aggregate only specific lines from each log file? Or just have all log files loaded in a single tab in LogFusion?

Meaning log4net has a pattern, i can identify with regex potentially.
However, when a stack trace error is thrown it can expand to multiple lines. However, each line correctly starts with the datetime value. I want to be able to use logfusion to view the entry, but view it in a single line as a single log entry.

I guess I'm wondering about the potential to designate my parsing of a log based on regex/using a template. I like logfusion's simplicty, but want an easier to read longer results

Ah ok. Could you send me a sample log, along with the regex you would use to filter it?

The key is that I currently have to use something like Log4view and GamutLogViewer to merge separate files into one timeline.

The key things I want to be able to do is provide a calculated diff column for delta between lines, and secondly to merge multiple files together and then sort them by datetime so that I can view one timeline of events between logs from multiple servers.

I attach a lorem example removing stack trace info. This might help give you an idea.

I also have some regex code that gets started (not perfect on the message part per multi-line implementation varies based on syntax)

commented out user, but i wanted to work on optional match column to see if it worked.

Any input on this yet? I find myself still using Sublime Text 3 for most of my log reviews due to the regex functionality. Being able to provide a template for regex parsing and merging of multiple logs together is pretty powerful in some tools. Would be awesome to add!

Not yet, sorry! We still have this as an open request on our list, so we'll be sure to post an update if/when we're able to add log combining and regex filtering
