Log files location?

[perqa]

I installed this cartridge without problems - thanks for great software! But I can't find the log files anymore. Are there any, or if not, how can I enable some node logs similar to Openshift's originals, located in nodejs/logs ?

The reason I'm asking is that my application doesn't start automatically when pushing to Openshift, but it starts if I do it manually using the same command as in package.json.

During the automated startup, I see the following (logshifter not found):

remote: Preparing build for deployment        
remote: Deployment id is a4df8975        
remote: Activating deployment        
remote: CLIENT_MESSAGE: Starting Node.js application...        
remote: /var/lib/openshift/58ef631bf9d320e77axxxxxx/nodejs/bin/control: line 46: /usr/bin/logshifter: No such file or directory        
remote: CLIENT_RESULT: Node.js application started.        
remote: Result: success        
remote: Activation status: success        
remote: Deployment completed with status: success

However, even though it looks like everything went fine, the app is inaccessible (Service Unavailable) until I start it manually using "node server.js"

That's strange. Everything works fine on a test deployment I've just created minutes ago.
/usr/bin/logshifter is present and the logs are created in ${OPENSHIFT_HOMEDIR}/app-root/logs/.

Just out of curiosity, what kind of account are you using?

The cartridge is tested and works perfectly on OpenShift Online, but it probably doesn't on OpenShift Enterprise, and most likely never will, since OpenShift didn't really provide any kind of feedback for past issues raised by Enterprise customers trying to use this cartridge...

Yes, you're probably right. The account belongs to the company I'm working for, and it says "Openshift Origin" top left.

I'm thinking I could create a standard NodeJS app on that account, and copy the bin/control file from there into this account (possibly with some adaptations) ... Do you think that would work?

[perqa]

Got it working in my Openshift environment with some minor changes to your bin/control file. I added two environment variables and changed a couple of lines in the start function.

# 
# Copy this file to $HOME/nodejs/bin/control  ("control" is the filename)
# 
export OPENSHIFT_NODEJS_LOG_DIR="/var/lib/openshift/<insert account-id>/nodejs/"
export OPENSHIFT_LOG_DIR=$OPENSHIFT_NODEJS_LOG_DIR
