Using openshift rhc tail command

问题

How do you tail openshift log files? I issued the following command:

rhc tail myapp

It seems to show first error line and then stops, but doesn't exit. If I press ctrl+C it asks whether to stop batch or not. How can I display last few errors and may be browse page by page? Is there page down/ page up shortcuts?

The 'rhc tail' command reads the last few lines of each of your log files and continues to feed subsequent log messages to your console. To view the entire log file, please review:

Adding -a option fix this issue for me.

rhc tail -a {app_name}

Openshift place logs in different files, so if you want get logs of a specific file then you can add -f file/address/and/name

Example :

rhc tail -f app-root/logs/nodejs.log -a myAppName

also you can ask for specific number of lines by adding -o "-n 40" in command. Above command will get last 40 lines.

Example :

rhc tail -f app-root/logs/nodejs.log -o "-n 40" -a myAppName

You can also download them:

$ scp  SHA@APP-DOMAIN.rhcloud.com:/var/lib/openshift/SHA/app-root/\
logs/APP.log "~/upstream.jbossas.log"

Feasible also in windows directly in git bash.
