When capturing a DSTRACE trace to a file, data similar to the following is displayed on each line:
3A3F94D9:361009361:d04dd980:047
Interpret this information as follows:
3A3F94D9 date and time in encoded format 361009361 seconds in encoded format d04dd980 process / thread number 047 DSTRACE filter number
The thread number is useful because you can follow the same thread of communication when you are troubleshooting a problem in a DSTRACE file. You'll notice that on busy servers the thread stops and starts. To ensure you are looking at relevant Directory Service communication, follow the same thread number back in the file.
The filter number is useful because it's sometimes not possible to work out which filter you need to use. Enable all filters, then look for a line in the DSTRACE file you recognize using the same filter number. Use the same filter as you would have used to capture that line in order to get at the data you need.
