I have a W3C logfile of IIS access log. I can't find out what the numbers mean:

2012-10-25 19:18:00 GET /status.aspx - 8080 - - 200 0 0 0

Of course some of the fields are clear, but what do the three zero's at the end stand for?

I didn't customize the logging in any way...

  • I'm stupid, didn't look at the top of the file, there's a header there! – Jaap Oct 25 '12 at 21:10

The header of the log file should contain a header which contains the fieldnames:

#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status time-taken
  • I don't have any headers in my log files, unfortunately. I can't check the settings without disabling logging, either, which seems crazy. – DCShannon May 10 '17 at 21:40
  • I gave up and disabled logging, but the Select Fields button is still grey, so I guess I can't look at the settings anyway. Argh. – DCShannon May 10 '17 at 21:45

To piggy back Jaap's answer:

"sc-" Server-to-client actions

sc-substatus - The substatus error code.
sc-win32-status - The Windows status code.
time-taken - The length of time that the action took, in milliseconds.
