In case a Docker host with installed Docker agent plugin (mk_docker) was monitored by multiple Checkmk sites, the Docker node info service might have sporadically reported UNKN with the following error message:
Plugin exception in section_node_disk_usage: [Errno 2] No such file or directory: '/var/lib/check_mk_agent/mk_docker_df.tmp....' -> '/var/lib/check_mk_agent/mk_docker_df.spool'
To benefit from this werk, users have to re-deploy the Docker agent plugin on affected hosts.
