Checkmk Werk 13506: Fix possible unhandled exception if site connection is encrypted

by Ronny Bruska

ID: 13506 Title: Fix possible unhandled exception if site connection is encrypted Component: Setup Level: 1 Class: Bug fix Version: 2.1.0i1 If you used the option "Encrypt data using TLS" for remote sites, the connection could not be established, showing the error "Unhandled exception: 30s while reading data from socket. Received data: {data.getbuffer().nbytes}/{size} bytes". This affected all encrypted livestatus connections in the Raw Edition and the connections in the Enterprise edition that did not use the Livestatus proxy daemon.

by Tom Baerwinkel

Checkmk Werk 13320: omd update: Add version compatibility barrier

by Lars Michelsen

ID: 13320 Title: omd update: Add version compatibility barrier Component: Site Management Level: 2 Class: New feature Version: 2.1.0i1 For some time now, we have been recommending that, in the case of major updates over several versions, the updates to the individual versions should be made in stages, e.g. in the case of a migration from 1.5 to 2.0, the version 1.5 should first be updated to 1.6 and then to 2.0. Furthermore, <tt>omd update</tt> does support downgrades to older major versions. However, a lot of manual adjustments are necessary to make the configuration and runtime data of the site compatible to an older major version again. So we don't recommend to do this step either. This change now introduces a hard barrier in the <tt>omd update</tt> command, which forces the above recommendations. Examples: <ul> <li>1.6 to 2.0 is allowed</li> <li>1.6 to 2.1 is blocked</li> <li>2.0 to 2.1 is allowed</li> <li>2.0 to 2.2 is blocked</li> <li>2.0 to 3.0 is allowed</li> <li>2.1 to 3.1 is allowed</li> </ul> You can disable this new check by using the <tt>omd -f update [site]</tt> command. However, sites that have been updated this way will no longer be supported by us.

Checkmk Werk 13190: veritas_vcs: cluster behaviour regresses from Checkmk version <= 1.6

by Lisa Pichler

ID: 13190 Title: veritas_vcs: cluster behaviour regresses from Checkmk version <= 1.6 Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 The veritas_vcs check determines the state of its service in the following way: OK: All nodes are running OK: At least one node is online or running, others may be offline WARN: All nodes are offline CRIT: At least one node is faulted UNKNOWN: At least one node is unknown (Of course this can be configurable). The cluster functionality of this check did not adhere to these priorities to determine the overall state of the clustered service. This has been fixed.

by Lisa Pichler

ID: 13189 Title: ps: irregular line continuation in Windows agent output leads to crash Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 In some cases, the agent output of the ps section contains processes that have a newline character in the process description, which caused the ps check to crash. This has been observed when an executable is run with parameters, e.g. <tt>myscript.exe -param1 val1 -param2 val2</tt>. This has been fixed
