| # 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) |
