Configuration of the showgraph cgi
critical.cgi(1) uses the configuration file $XYMONHOME/etc/critical.cfg to determine which of the statuses currently in a red or yellow state should appear on the Critical Systems view.
This file should not be edited manually. It is maintained by the criticaleditor.cgi(1) utility via a web-based frontend.
Since the file is maintained by a web front-end tool, the userid running Web CGI scripts must have write-permission to the file. Typically, this means it must have a group-ownership matching your webserver userid, and group-write permissions (mode 664).
When editing the file with the web front-end, a backup file is created. Therefore the critical.cfg.bak file should have identical permissions.
