How does both rules works, and can we combine both rules? First, you can't combine both rules. Both rules are standalone rules
Enabled section for Windows
By default, all the sections will be executed. Sections that are not selected here will be skipped. Skipping sections reduces CPU load on the monitored host and the amount of transferred data. However, it may result in the absence of the associated Checkmk service or services. The most CPU performance is needed by the Eventlog monitoring and the performance counters.
Disabled section for Windows
This option allows skipping specific sections of the Checkmk agent. By default, all the sections will be executed. Selected sections will not be executed by the agent. Skipping sections reduces CPU load on the monitored host and the amount of transferred data. However, it may result in the absence of the associated Checkmk service or services.
How should we use the rules?
We recommend to use only one of these rules. With the "enabled" rule you can define a set of sections which should be enabled by the agent directly. In such a case you want to disable a section e.g. Windows counter due to long-running WMI commandc, you should use the disabled rule, or you deselect this entry in the enabled rule.
A short example
Let's go one step further and imagine the following scenario: Per default you want to disable the Windows Logwatch
