Fixed In Version: rubygem-openshift-origin-frontend-apache-vhost-0.2.3-1
Doc Type: Bug Fix
Doc Text:
Existing vhost templates referenced a variable that is only available when using the mod-rewrite front-end proxy plug-in. Therefore, gear server names were not logged in the /var/log/httpd/openshift_log file, causing disruptions in gear idling functions. This bug fix improves the custom access log format to ensure the server name is included, and gear idling functions are no longer impacted. These steps are recommended only for systems where the rubygem-openshift-origin-frontend-apache-vhost package is installed. For the updated package to take effect, the following commands must be run on affected node hosts. Please note that this will cause a node outage, and must be done with care. See the OpenShift Enterprise Administration Guide for full documentation on modifying the front-end proxy server plug-in configuration. # oo-frontend-plugin-modify --save > filename # oo-frontend-plugin-modify --delete # oo-frontend-plugin-modify --restore < filename

Description Brenton Leanhardt 2014-01-29 11:10:03 EST 
Description of problem:

Today our vhost templates reference a variable that is only available when using mod-rewrite.  Therefore the servername for an application is not properly logged.

To manually fix this you can edit the following files:

/var/lib/openshift/.httpd.d/frontend-vhost-https-template.erb
/var/lib/openshift/.httpd.d/frontend-vhost-http-template.erb

From there you will need to save, delete and restore the frontends.  This will create an outage on a node so it should be done with care.

See https://access.redhat.com/site/documentation/en-US/OpenShift_Enterprise/2/html-single/Administration_Guide/#Changing_Front-end_HTTP_Server_Plug-in_Configuration for full documentation.

For someone already using the vhost plugin the steps would be as follows:

# oo-frontend-plugin-modify --save > filename
# oo-frontend-plugin-modify --delete
# oo-frontend-plugin-modify --restore < filename
Comment 3 Luke Meyer 2014-01-29 14:27:39 EST 
And the reason we care, I believe, is because this is the log that's used by the idler to determine whether and app has been accessed recently or is a candidate for idling.
Comment 4 Luke Meyer 2014-01-29 15:08:46 EST 
BTW please upstream this change... right?

    Fix the Apache vhost plugin
    
    Fix bug in the Apache vhost plugin that prevented it from functioning.
    
    Change V_MATCH_HOST to %v in custom access log format so the server name
    is included in the log (V_MATCH_HOST is only available when using the
    mod rewrite plugin).
