Title: Kill forked processes by mk_oracle under AIX Class: fix Compatible: compat Component: checks Date: 1709728993 Edition: cre Level: 1 Version: 2.2.0p25 The agent plugin <code>mk_oracle</code> creates forked processes, e.g. from <code>sqlplus</code>.

[2.2.0] Checkmk Werk 16210 adapted: folder_config: Prevent unintentional deletion of a non-empty folder

by Checkmk werks level 1

Werk 16210 was adapted. The following is the new Werk, a diff is shown at the end of the message. Title: folder_config: Prevent unintentional deletion of a non-empty folder Class: fix Compatible: incomp Component: rest-api Date: 1704965695 Edition: cre Level: 1 Version: 2.2.0p25 Prior to this Werk, the REST API could delete non-empty folders without any further check. With this Werk, the endpoint now accepts the delete_method query parameter. The possible values are: - recursive: Deletes the folder and all the elements it contains. - abort_on_nonempty: Deletes the folder only if it is not empty If no delete_method is provided, recursive is asumed and the behaviour is the same as before this Werk. The enpoint will return a 409 status code when trying to delete a folder that contains hosts, rules, subfolders or is referenced by another object. Use example: <code>curl -X 'DELETE' 'http://example.com/my_site/check_mk/api/1.0/objects/folder_config/my_folder…' -H 'accept: /</code> ------------------------------------<diff>------------------------------------------- Title: folder_config: Prevent unintentional deletion of a non-empty folder Class: fix Compatible: incomp Component: rest-api Date: 1704965695 Edition: cre Level: 1 - Version: 2.2.0p24 ? ^ + Version: 2.2.0p25 ? ^ Prior to this Werk, the REST API could delete non-empty folders without any further check.

Title: quantum_libsmall_*: Improve SNMP detection Class: fix Compatible: compat Component: checks Date: 1709035896 Edition: cre Level: 1 Version: 2.2.0p25 Currently the SNMP detection for <code>quantum_libsmall_status</code> and <code>quantum_libsmall_door</code> checks if "linux" and "library" are contained in the sysDescr and sysLocation OIDs.

Title: size_trend: Treat negative free space as 0 in all cases Class: fix Compatible: compat Component: checks Date: 1710929049 Edition: cre Level: 1 Version: 2.2.0p25 Before the version 2.2.0p21, 'Time left until full' was reported to be 0 in case of devices reporting negative free space. With werk 16330, we stopped reporting the metric in case of very small size changes because it lead to infinite values. With this change the behavior was unintentionally also changed for negative free space values. This werk restores the same functionality in case of negative free space. ------------------------------------<diff>------------------------------------------- Title: size_trend: Treat negative free space as 0 in all cases Class: fix Compatible: compat Component: checks Date: 1710929049 Edition: cre Level: 1 - Version: 2.2.0p24 ? ^ + Version: 2.2.0p25 ? ^ Before the version 2.2.0p21, 'Time left until full' was reported to be 0 in case of devices reporting negative free space.

Title: folder_config: Extend GET and DELETE endpoints folder name pattern to match the CREATE enpoint one Class: fix Compatible: compat Component: rest-api Date: 1696846527 Edition: cre Level: 1 Version: 2.2.0p25 Prior to this Werk, the folder name pattern for GET and DELETE endpoints did not allow the use of unicode characters while they were supported by the CREATE endpoint, with the result that folders created with such characters could not be accessed or deleted from the REST API. For example, the user was able to create a folder named û亿Ï8Ĺ, which then could not be read or deleted from the API. This Werk widens the folder name pattern on GET and DELETE endpoints to align with the CREATE one and now all of them support unicode characters. ------------------------------------<diff>------------------------------------------- Title: folder_config: Extend GET and DELETE endpoints folder name pattern to match the CREATE enpoint one Class: fix Compatible: compat Component: rest-api Date: 1696846527 Edition: cre Level: 1 - Version: 2.2.0p24 ? ^ + Version: 2.2.0p25 ? ^ Prior to this Werk, the folder name pattern for GET and DELETE endpoints did not allow the use of unicode characters while they were supported by the CREATE endpoint, with the result that folders created with such characters could not be accessed or deleted from the REST API.
