the variables will be substituted with the actual hostname and IP address of the system, as recorded in
RHN’s System Profile, such as:
hostname=test.example.domain.com
ip_address=177.18.54.7
To capture custom system information, insert the key label into the custom information macro
(rhn.system.custom_info). For instance, if you developed a key labeled "asset" you can add it to the
custom information macro in a configuration file to have the value substituted on any system
containing it. The macro would look like this:
asset={@ rhn.system.custom_info(asset) @}
Upon deployment of the file to a system containing a value for that key, the macro gets translated,
such as:
asset=Example#456
To include a default value, for instance if one is required to prevent errors, you can append it to the
custom information macro, like so:
asset={@ rhn.system.custom_info(asset) = ’Asset #’ @}
This default will be overridden by the actual value on any system containing it. For instructions on
developing custom system information keys, refer to Section 6.4.9
Custom System Info — .
Using the
Red Hat Network Configuration Manager
(
rhncfg-manager
) will not translate or alter
files, as that tool is system agnostic. Binary files cannot be interpolated.
6.7. Schedule
If you click the Schedule tab on the top navigation bar, the Schedule category and links appear.
These pages enable you to keep track of the actions taking place within your systems. An action is a
scheduled RHN task that is to be performed on one or more client systems. For example, an action
can be scheduled to apply all Errata Updates to a system.
Red Hat Network keeps track of the following action types:
1. Package Alteration (installation, upgrade, and removal)
2. Rollback Package Actions
3. System Reboots
4. Errata Updates
5. Configuration File Alteration (deploy, upload, and diff)
6. Hardware Profile Updates
7. Package List Profile Updates
8. Kickstart Initiation
9. Remote Commands
Each page in the
Schedule
category represents an action status.
