Checkmk Werk 15435: password: return better responses for GET collection

by Gav

ID: 15435 Title: password: return better responses for GET collection Component: REST API Level: 1 Class: Bug fix Version: 2.3.0b1 Previously when calling the password GET collection endpoint, the value attribute would only contain the following information for each password C+: { "domainType": "dict", "title": "Kubernetes login" } C-: It now contains links + the expected password information.

Checkmk Werk 14589: apache_status: Handle Permission Errors

by Solomon Jacobs

ID: 14589 Title: apache_status: Handle Permission Errors Component: Checks & agents Level: 1 Class: Bug fix Version: 2.3.0b1 If {ENABLE_OMD_SITE_DETECTION} is set to True and the file /opt/omd/sites/{site_name}/etc/apache/listen-port.conf is not accessible, then the agent plugin apache_status.py would not produce parseable data. With this werk, the respective data is skipped.

Checkmk Werk 15417: mk_logwatch: Correctly handle UNIX paths with non-UTF-8 characters

by Andreas Umbreit

ID: 15417 Title: mk_logwatch: Correctly handle UNIX paths with non-UTF-8 characters Component: Checks & agents Level: 1 Class: Bug fix Version: 2.3.0b1 On UNIX, filenames may consist of arbitrary bytes. To display filenames in Checkmk, the mk_logwatch plugin assumes a UTF-8 encoding and previously replaced each non-UTF-8 (hence non-printable) byte with the replacement character �. This lead to the problem that multiple filenames were represented by the same name in Checkmk. As a result, the logfiles got displayed in one service, with the logfile contents merged to one log view. In order to handle this situation, mk_logwatch now uses a backslash escape sequence instead of the replacement character. Non-UTF-8 bytes are now represented by their hexadecimal value with a <tt>\x</tt> prefix. E.g., monitoring the two files (as shown with <tt>ls</tt>, i.e., with octal escape sequence) <tt>'my'$'\300\201''file'</tt> and <tt>'my'$'\300\200''file</tt> now yields two services Log my\xc0\x80file and Log my\xc0\x81file, while it used to yield only one service Log my��file before. Due to the new service name, you have to discover the newly named services if you are affected by this change.

Checkmk Werk 15153: azure_virtual_machine: Redesign service rule

by Sofia Colakovic

ID: 15153 Title: azure_virtual_machine: Redesign service rule Component: Checks & agents Level: 1 Class: Bug fix Version: 2.3.0b1 Previously, if a mapping for power or provisioning states was configured for some, but not for all states, the unconfigured states would always be mapped to WARN. This behavior was confusing and forced the users to configure mapping for all the states even when they wanted to change the behavior of only one. Moreover, since the parameters of the rule used to be groups of states, the rule matching could not take place at the state level. With this werk, if you configure the state mapping for a single state the state mapping of all other states will be unaffected. Previously existing rules are updated to keep the same functionality as before.
