I've recently configured svn usage logs with:
LogFormat "%h %t %u (%{SVN-REPOS-NAME}e %{SVN-ACTION}e) %s (%I/%O in %Ts) %k
\"%{User-Agent}i\"" svn
CustomLog /var/log/svn/svn-usage.log svn env=SVN-ACTION
mod_logio is enabled, so I'm getting values written to each of the above
fields, but when testing with a full checkout of a ~420Mb repo (excluding
pristine), I get variable results depending on the client. Sometimes the log
entry appears within 4 seconds and reports ~1MB:
192.168.1.2 [01/Oct/2015:11:42:50 +0100] user (svn get-inherited-props /trunk
r1084) 200 (543/292 in 0s) 4 "SVN/1.8.13 (x64-microsoft-windows) serf/1.3.8"
192.168.1.2 [01/Oct/2015:11:42:50 +0100] user (svn checkout-or-export /trunk
r1084) 200 (726/11527999 in 11s) 5 "SVN/1.8.13 (x64-microsoft-windows)
serf/1.3.8"
Sometimes the log only reports the checkout, but with the correct size:
192.168.1.2 [01/Oct/2015:11:43:55 +0100] user (svn checkout-or-export /trunk
r1084) 200 (729/665066747 in 171s) 3 "SVN/1.7.20 neon/0.29.6"
The exact %I, %O and %T will vary a little with each test, but the log entry
appears after the first ~5s/~10MB of a checkout that takes 3 minutes. The
difference between the above two is that the first checkout is via command-line
SVn (part of Tortoise), using Serf and the latter is via the OSX developer
tools svn command line (Currently 1.7.20 and built against Neon).
I've disabled compression both at SVNCompressionLevel and disabling
mod_deflate. (The data sizes logged were much smaller previously, but the issue
was still there).
Is there a way I can ensure the log is only written after the full request has
been serviced? The data over time will be really useful in gauging usage over
time.
