This label was detected based on the asynchronously created agent section <<<omd_status>>>. Because this section is not immediately available on the first agent contact, this resulted in a label discovery after the second check cycle.

Another issue was that the <<<omd_status>>> section was produced by non Checkmk servers with older agent versions. This lead to a wrong label discovery.

We now use the dedicated <<<labels>>> section to create the label which is produced once we find the command 'omd' on a system.
