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 :) ]]> RE: log4net multiline support https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#7 Tue, 27 Sep 2016 15:01:52 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#7 LogFusion 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! ]]> RE: log4net multiline support https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#6 Fri, 24 Jun 2016 19:50:14 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#6 LogFusion Excellent, thanks! We'll see what we can do :) ]]> RE: log4net multiline support https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#5 Fri, 24 Jun 2016 17:25:50 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#5 LogFusion 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)

Log4Net - Multiline Format
commented out user, but i wanted to work on optional match column to see if it worked.

Code
Copy
Select All

^(?<DateTime>(?:\d{4})-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2},\d{3})\s*
(?:\[)(?<ThreadID>\d*)(?:\]\s*)
(?<LogType>\w+)\s+
(?<Loger>\w+)\s+-\s+
#(?<User>(\w|[=\\])*(?=:?\:?\s*))?
(?<Message>.*)$

Could you send me a sample log, along with the regex you would use to filter it? ]]> RE: log4net multiline support https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#3 Fri, 29 Jan 2016 15:18:48 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#3 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 ]]> RE: log4net multiline support https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#2 Tue, 05 Jan 2016 19:54:29 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f#2 LogFusion 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? ]]> log4net multiline support https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f Mon, 04 Jan 2016 16:58:31 GMT Binary Fortress Software https://www.logfusion.ca/Discussions/View/log4net-multiline-support/?ID=ebd8e191-d273-428e-9b9a-dbfb88c5ba6f LogFusion 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? ]]>
