[Qgis-user] QGIS Server Log Stderr

[Thomas Schüttenberg]

Hi Björn,
thanks for investigating, but no, I still don't get this. 
With 
ErrorLog "${STACK}/logs/error.log"
in httpd.conf (plus LogLevel info to make sure there will be something to log) and
FcgidInitialEnv QGIS_SERVER_LOG_STDERR 1
plus FcgidInitialEnv QGIS_SERVER_LOG_LEVEL 0
in the QGIS server vHost.conf, there is no log output from QGIS server in error.log while restarting the Apache. I would expect the QGIS server summary[1] like I see in the QGIS_SERVER_LOG_FILE, not only the Apache restart lines.

You received the STDERR log on Ubuntu not Windows, right?
I think I stick with QGIS_SERVER_LOG_FILE for now.
