I'm looking for the location of the NuoCollection Agent log. What is the nuoca.log location?
The nuoca.log file is located in $NUODB_LOGDIR.
On a Linux package install $NUODB_LOGDIR would be `/var/log/nuodb`.
For Tarball installs, it will be based on where you chose to install NuoDB.
You can find more information about environment variables here.
