Checkmk Werk 12782: Activate inventory for kubernetes objects

by Benedikt Seidl

ID: 12782 Title: Activate inventory for kubernetes objects Component: HW/SW Inventory Level: 1 Class: Bug fix Version: 2.1.0i1 A host is created for each kubernetes endpoint. On a checkmk site with disabled inventory (the default) the endpoint host does not have any services. As Hosts without services are invalid, checkmk automatically adds a ping service which fails, because the endpoint host is created from piggyback data and ist not reachable. The error message looks like: "check_icmp: No hosts to check" This werk adds the label "cmk/kubernetes:yes" to kubernetes related hosts, so the issue can now be fixed by creating an inventory rule that activates the inventory on kubernetes endpoint hosts: Go to "Setup" → "HW/SW inventory rules" → "Do hardware/software inventory" → "Create rule in folder": <ul> <li>"Status data inventory" → "Do status data inventory"</li> <li>"Host labels" → "has" → "cmk/kubernetes:yes"</li> → Save This werk alters the default configuration. Sites created with checkmk 2.0.0p4 or later automatically enable the inventory for kubernetes objects.

Checkmk Werk 12735: SMART agent plugin: Exclude devices which can read CDs

by External contributor

ID: 12735 Title: SMART agent plugin: Exclude devices which can read CDs Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The SMART agent plugin now attempts to exclude devices which can read CDs. Such devices do not support SMART and not excluding them can lead to hanging <tt>smartctls</tt> processes. The plugin attempts to exclude such devices based on the output of <tt>udevadm</tt>, if this command is found. Note that you need to update the agents on affected linux hosts for this werk to come into effect.

Checkmk Werk 12808: check_mail_loop: crash RuntimeError("Server responded b'+OK 1 messages:', [...]")

by Ulrich Bschorer

ID: 12808 Title: check_mail_loop: crash RuntimeError("Server responded b'+OK 1 messages:', [...]") Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The active check check_mail_loop crashed with the error "RuntimeError("Server responded b'+OK 1 messages:', [...]")" if the response from the server contained more characters than just "+OK". E.g. the result "+OK, 1 messages" would have lead to an error. The bugfix contains a more tolerant verification of the result.

Checkmk Werk 12828: Distributed setup: Fix parallel activations breaking remote sites

by Lars Michelsen

ID: 12828 Title: Distributed setup: Fix parallel activations breaking remote sites Component: Setup Level: 2 Class: Bug fix Version: 2.1.0i1 Previous 2.0.0 versions could break the Checkmk configuration on remote sites when two users tried to activate changes for a single remote site at the same time. This was a race condition between both processes. While the first activation performed the synchronization to the remote site, the second activation could modify the files that are currently being synchronized by the first process. This could lead to incomplete configurations on the remote site. Since the first activation did not know anything about this inconsistency, it tried to activate the incomplete configuration on the remote site after the sychronization which could fail with different error messages depending on which files were not transfered. This issue only affected the configuration of remote sites. No configuration was lost on the central site. If you want to prevent this issue with previous 2.0.0 releases, you need to ensure that you don't start two activations for a site at the same time.

Checkmk Werk 12511: Any custom Perf-O-Meter destroyed all Perf-O-Meters

by Moritz Kiemer
