[logback-dev] [JIRA] Commented: (LBCLASSIC-227) HOSTNAME property not resolved

[Ceki Gulcu (JIRA)]

    [ http://jira.qos.ch/browse/LBCLASSIC-227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=11958#action_11958 ] 

Ceki Gulcu commented on LBCLASSIC-227:
--------------------------------------

In the chapter on groovy [1], there is a section on the hostname variable. Search "Automatically exported fields".  The paragraph starting with "If you wish to have the hostname variable be seen in all scopes, ..." is particularly relevant in this context.

Please close this report if the above information solved the issue.
