Checkmk Werk 13468: mrpe: Do not crash upon invalid metrics

by Moritz Kiemer

ID: 13468 Title: mrpe: Do not crash upon invalid metrics Component: Checks & agents Level: 1 Class: New feature Version: 2.1.0i1 In Checkmk versions prior to 2.0, invalid performance data strings passed by the MRPE plugin have been ignored. In Checkmk 2.0 the parsing would find those invalid strings, and crash upon them. This is generally the desired behaviour (see <a href=https://docs.checkmk.com/latest/en/devel_check_plugins.html#errors>the documentation</a> for a rationale). However, since MRPE comprises a lot of different plugins, an all-or-nothing approach is rather inconvenient. We now parse everything as good as we can, and issue an <tt>UNKNOWN</tt> state for the affected service.

Checkmk Werk 13387: Improve usability of "Create rule" buttons

by Kenneth Okoh

ID: 13387 Title: Improve usability of "Create rule" buttons Component: Multisite Level: 1 Class: New feature Version: 2.1.0i1 So far the "Create rule" buttons were positioned at the bottom of a ruleset page and did not fit in with the standard Checkmk buttons. These buttons are now located at the top of the page as page menu suggestions and yield several more intuitive options for preselecting folder, host and service/device before entering the rule properties dialog. Also, "Create rule" is reworded to "Add rule".

Checkmk Werk 13076: REST API missing and duplicated hosts problem

by Christoph Rauch

ID: 13076 Title: REST API missing and duplicated hosts problem Component: Core & setup Level: 3 Class: Bug fix Version: 2.1.0i1 This Werk fixes a very severe data inconsistency problem in the REST API. Previously, only the actual working code of the individual endpoints were locked, but the validation logic which gets executed before the endpoints didn't fall into that locking scope. This logic could then trigger a cache load which could lead to data inconsistency and even data loss when using the REST API highly concurrently. The observed effects were: * when moving hosts concurrently, some hosts may disappear * when moving hosts concurrently, some hosts may end up in multiple folders * when editing hosts, spurious 421 or 401 responses could appear The locks have now been modified to encompass also the validation logic. This Werk fixes the afore mentioned problems. There are no further actions to be taken.

Checkmk Werk 13077: fix REST API ETag configuration option

by Christoph Rauch

ID: 13077 Title: fix REST API ETag configuration option Component: Core & setup Level: 1 Class: Bug fix Version: 2.1.0i1 The configuration option for the ETags, previously introduced in Werk 11938 did not show up in the global configuration setup GUI. This was due to a bug, which this Werk fixes. The ETag functionality can now be turned on/off through the "Global settings > Site Management > REST API: Use HTTP ETags for optimistic locking" configuration value.
