# parselog.py, written and contributed by Kevin Marks
#
# Requires OS X 10.3 Panther or later, for Python and Core Graphics Python APIs
# Invoke from the command line with "parselog.py fname" where fname is a log file made by mDNSNetMonitor
#
# Caveats:
# It expects plain ASCII, and doesn't handle spaces in record names very well right now
# There's a procedure you can follow to 'sanitize' an mDNSNetMonitor log file to make it more paletable to parselog.py:
# 1. Run mDNSNetMonitor in a terminal window.
# When you have enough traffic, type Ctrl-C and save the content of the terminal window to disk.
# Alternatively, you can use "mDNSNetMonitor > logfile" to write the text directly to a file.
# You now have a UTF-8 text file.
# 2. Open the UTF-8 text file using BBEdit or some other text editor.
# (These instructions are for BBEdit, which I highly recommend you use when doing this.)
# 3. Make sure BBEdit correctly interprets the file as UTF-8.
# Either set your "Text Files Opening" preference to "UTF-8 no BOM", and drop the file onto BBEdit,
# or manually open the File using "File -> Open" and make sure the "Read As" setting is set to "UTF-8 no BOM"
# Check in the document pulldown menu in the window toolbar to make sure that it says "Encoding: UTF-8 no BOM"
# 4. Use "Tools -> Convert to ASCII" to replace all special characters with their seven-bit ascii equivalents.
# (e.g. curly quotes are converted to straight quotes)
# 5. Do a grep search and replace. (Cmd-F; make sure Grep checkbox is turned on.)
# Enter this search text : ^(.................\(................\S*) (.* -> .*)$
# Enter this replacement text: \1-\2
# Click "Replace All"
# Press Cmd-Opt-= repeatedly until there are no more instances to be replaced.
# You now have text file with all spaces in names changed to hyphens
# 6. Save the new file. You can save it as "UTF-8 no BOM", or as "Mac Roman". It really doesn't matter which --
# the file now contains only seven-bit ascii, so it's all the same no matter how you save it.
# 7. Run "parselog.py fname"
# 8. Open the resulting fname.pdf file with a PDF viewer like Preview on OS X
#
# Key to what you see:
# Time is on the horizontal axis
# Individual machines are shown on the vertical axis
# Filled red circle: Normal query Hollow red circle: Query requesting unicast reply
# Filled orange circle: Probe (service starting) Hollow orange circle: First probe (requesting unicast reply)
# Filled green circle: Normal answer Hollow green circle: Goodbye message (record going away)
# Hollow blue circle: Legacy query (from old client)
