In case a docker node section can not be computed by the mk_docker agent plugin, the "Docker node info" service reports about the error in detail. Until this werk, the "Check_MK" service did also raise an issue regarding the missing agent section, like: "Missing monitoring data for plugins: docker_node_disk_usage". This duplicate information is now suppressed, reducing the number of notification Checkmk produces in such situations.
