Agent configuration settings are normally specified for a host using the Web UI. However, if a custom configuration channel is created for a host set, any agent configuration settings established using the Web UI are ignored for the hosts included in that host set.
To return to using the Web UI agent settings instead of the custom configuration channel settings for a host, you must first remove the host sets that include that host from any custom configuration channels.
As long as a host is included in a host set used by a custom configuration channel, its agent settings are established by the custom configuration channel. When a host is no longer included in a host set used by a custom configuration channel, its agent settings are established by the Web UI settings.
In addition, if a host is included in multiple host sets with different custom configuration channels, channel priority numbers are used to determine which agent settings apply to the host. See Understanding Configuration Channel Priorities.
