Checkmk Werk 15657: Agent controller: Changes in the output format of the status command

ID: 15657 Title: Agent controller: Changes in the output format of the status command Component: agents Level: 1 Class: New feature Version: 2.3.0b1 This werk is only incompatible for users who process the json output of the agent controller status command (<tt>cmk-agent-ctl status --json</tt>). For all other users, this werk is purely informational. The human-readable output of the status command has changed as follows: LI: The section about the remote status of a connection does not report `Registration state: operational` anymore, since this was redundant information. If the host is registered, we now simply report hostname and connection mode. LI: If the host is not registered anymore at the monitoring site, we now report `Not registered`. Before, the controller reported a 404 error with a description stating that the host is not registered. These changes are also reflected in the new json schema for the remote status, which reads C+: {"status": "Registered", "hostname": "...", "connection_mode": "..."} C-: for registered hosts and C+: {"status":"NotRegistered"} C-: for hosts which are not registered.
