tool analyzing log4net logs

Question

Is there a tool which can be used to analyze log4net logs.

Particulary I would like to extract two method calls by thread id and analyze the duration between the two, to create some statistics of call duration.

Plus this over multiple (100x10Mb) files.

I suppose grep would also do it.

Answer 1

Well this may or may not be a bad answer, but when you use log4j, there's a tool called Chainsaw (written in Java) that you can use to filter and go through your log4j-like log files.

Note: You may need to refer to this article to configure chainsaw to read your log file file:

Answer 2

If you are using the XML log formatting. You can process the log files. using xpath to extract the details you want. But you would have a write a small app yourself.

Answer 3

In case you use the XML Log you could write a XSL Stylesheet and reference it from the XML. Then you just need to point your browser to the XML and it will style the XML with your XSL Stylesheet for you to see the data as HTML (or whatever, XSL is very powerful).
