| 18 | # parselog.py, written and contributed by Kevin Marks |
|---|
| 19 | # |
|---|
| 20 | # Requires OS X 10.3 Panther or later, for Python and Core Graphics Python APIs |
|---|
| 21 | # Invoke from the command line with "parselog.py fname" where fname is a log file made by mDNSNetMonitor |
|---|
| 22 | # |
|---|
| 23 | # Caveats: |
|---|
| 24 | # It expects plain ASCII, and doesn't handle spaces in record names very well right now |
|---|
| 25 | # There's a procedure you can follow to 'sanitize' an mDNSNetMonitor log file to make it more paletable to parselog.py: |
|---|
| 26 | # 1. Run mDNSNetMonitor in a terminal window. |
|---|
| 27 | # When you have enough traffic, type Ctrl-C and save the content of the terminal window to disk. |
|---|
| 28 | # Alternatively, you can use "mDNSNetMonitor > logfile" to write the text directly to a file. |
|---|
| 29 | # You now have a UTF-8 text file. |
|---|
| 30 | # 2. Open the UTF-8 text file using BBEdit or some other text editor. |
|---|
| 31 | # (These instructions are for BBEdit, which I highly recommend you use when doing this.) |
|---|
| 32 | # 3. Make sure BBEdit correctly interprets the file as UTF-8. |
|---|
| 33 | # Either set your "Text Files Opening" preference to "UTF-8 no BOM", and drop the file onto BBEdit, |
|---|
| 34 | # or manually open the File using "File -> Open" and make sure the "Read As" setting is set to "UTF-8 no BOM" |
|---|
| 35 | # Check in the document pulldown menu in the window toolbar to make sure that it says "Encoding: UTF-8 no BOM" |
|---|
| 36 | # 4. Use "Tools -> Convert to ASCII" to replace all special characters with their seven-bit ascii equivalents. |
|---|
| 37 | # (e.g. curly quotes are converted to straight quotes) |
|---|
| 38 | # 5. Do a grep search and replace. (Cmd-F; make sure Grep checkbox is turned on.) |
|---|
| 39 | # Enter this search text : ^(.................\(................\S*) (.* -> .*)$ |
|---|
| 40 | # Enter this replacement text: \1-\2 |
|---|
| 41 | # Click "Replace All" |
|---|
| 42 | # Press Cmd-Opt-= repeatedly until there are no more instances to be replaced. |
|---|
| 43 | # You now have text file with all spaces in names changed to hyphens |
|---|
| 44 | # 6. Save the new file. You can save it as "UTF-8 no BOM", or as "Mac Roman". It really doesn't matter which -- |
|---|
| 45 | # the file now contains only seven-bit ascii, so it's all the same no matter how you save it. |
|---|
| 46 | # 7. Run "parselog.py fname" |
|---|
| 47 | # 8. Open the resulting fname.pdf file with a PDF viewer like Preview on OS X |
|---|
| 48 | # |
|---|
| 49 | # Key to what you see: |
|---|
| 50 | # Time is on the horizontal axis |
|---|
| 51 | # Individual machines are shown on the vertical axis |
|---|
| 52 | # Filled red circle: Normal query Hollow red circle: Query requesting unicast reply |
|---|
| 53 | # Filled orange circle: Probe (service starting) Hollow orange circle: First probe (requesting unicast reply) |
