The log file navigator, lnav, is an enhanced log file viewer that
|
|
|
|
|
takes advantage of any semantic information that can be gleaned from
|
|
|
|
|
the files being viewed, such as timestamps and log levels. Using this
|
|
|
|
|
extra semantic information, lnav can do things like interleaving
|
|
|
|
|
messages from different files, generate histograms of messages over
|
|
|
|
|
time, and providing hotkeys for navigating through the file. It is
|
|
|
|
|
hoped that these features will allow the user to quickly and
|
|
|
|
|
efficiently zero in on problems.
