Checkmk Werk 13213: real-time-checks: fix decryption if agent encryption is anabled

by Moritz Kiemer

ID: 13213 Title: real-time-checks: fix decryption if agent encryption is anabled Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 Since version 1.2.9 the real time check encryption did not work if the agent encryption was activated, as the agent also uses the corresponding secret to encrypt the payload of the real-time UDP packets in this case. The Checkmk server now follows this logic when encrypting the packets.

Checkmk Werk 13238: Fix possible core restart of remote sites on every activating of changes

by Ronny Bruska

ID: 13238 Title: Fix possible core restart of remote sites on every activating of changes Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 If you used local plugins within "~/local/lib/python3/cmk/base/plugins/agent_based/", the folder "__pycache__" was always synchronized from the central to the remote site. This caused problems if the timestamps of the plugins differed on central and remote site. The remote site would than need a core restart on every activating of changes. Therefore, this folder is not synched anymore. Workaround was, to delete the files located within "~/local/lib/python3/cmk/base/plugins/agent_based/" on the affected site, do a dummy change for that site on the central site and activate changes again.

Checkmk Werk 13251: netapp_api_temp: crash on access to non-existing key 'temp-sensor-current-temperature'

by Frans Fürst

ID: 13251 Title: netapp_api_temp: crash on access to non-existing key 'temp-sensor-current-temperature' Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The check function assumes there's a key 'temp-sensor-current-temperature' for every `netapp_api_temp` section element and runs into a KeyError if that isn't the case. This change preprocesses all entries in a way that only valid entries containing 'temp-sensor-current-temperature' will be processed.

Checkmk Werk 13231: Fix source of painter "Docker node"

by Ronny Bruska

ID: 13231 Title: Fix source of painter "Docker node" Component: Multisite Level: 1 Class: Bug fix Version: 2.1.0i1 The painter, used in views like e.g. "Docker containers", used host labels as its source. That could lead to wrong results, if the container is already running on another node but the host label was not updated yet. We now take the service "Docker container status" to determine the current node of a container.

Checkmk Werk 13211: Fix 'only from' monitoring in Check_MK services for systemd hosts

by Moritz Kiemer

ID: 13211 Title: Fix 'only from' monitoring in Check_MK services for systemd hosts Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The Check_MK service did not report the only-from configuration if the used super server was <tt>systemd</tt> and the socket unit name did not start with 'check-mk-agent'. This can either be the case if you are using the Checkmk raw edition, or you have changed the agent package name via the WATO. While the only-from setting was enforced correctly, the agent did not report it back to the monitoring server. If the agent reports back the effective only-from, the monitoring server will compare it to the configured value, and issues a WARNING if the allowed IP addresses deviate from the expected ones.
