[2.4.0] Checkmk Werk 15514 created: check_httpv2: Introduce a reworked way to test web sites

by Checkmk werks level 1

[//]: # (werk v2) # check_httpv2: Introduce a reworked way to test web sites key | value ---------- | --- date | 2024-03-08T10:06:58+00:00 version | 2.4.0b1 class | feature edition | cre component | checks level | 2 compatible | no The legacy http monitoring plugin caused quite some trouble over the last years. This included lots of effort to add features or just simply fixing bugs. With the new plugin, the functionality is moved to maintainable and extendable code completely under control of Checkmk. This means also breaking changes with the old plugin: * Some metrics are not available anymore as it has been known. We discovered that these are simply not directly understandable. Instead we will add metrics as needed in the future. Some metrics will already be added in this first release * Some functionality has been a workaround and is now implemented directly into the new plugin. This makes it hard to migrate rules automatically. * Users are now able to decide on their own which functionality should be in an own service. This means, that it is now possible to test the certificate validity and response times in one service, if needed. * User are able to configure multiple http checks within one rule. You can provide standard settings to be used for all endpoints, and overwrite them per entry for each endpoint. Migrating manually makes absolute sense here. Please note that we will not remove the old plugin for now. We understand that you need some time to migrate your configurations. Nethertheless, we will deprecate the old plugin and eventually remove it from Checkmk.

[2.4.0] Checkmk Werk 16526 created: password: the response schema now matches what is returned

by Checkmk werks level 1

[//]: # (werk v2) # password: the response schema now matches what is returned key | value ---------- | --- date | 2024-03-07T09:18:40+00:00 version | 2.4.0b1 class | fix edition | cre component | rest-api level | 1 compatible | yes This werk addresses an issue with the REST-API password endpoint response. The response schema listed the title and the ident as fields that should be returned but we were not returning them as part of the password object. These have now been removed from the schema. Also, the members field was returning invalid information and hence has been removed.

[2.4.0] Checkmk Werk 16614 created: Ignore CAs with negative serial numbers

by Checkmk werks level 1

[//]: # (werk v2) # Ignore CAs with negative serial numbers key | value ---------- | --- date | 2024-03-11T10:43:27+00:00 version | 2.4.0b1 class | fix edition | cre component | core level | 1 compatible | no When Checkmk is configured to *Trust system wide configured CAs* the system CA store is traversed and the certificates are added to the trusted CAs. With RFC 5280 certificate serial numbers are required to be positive. Unfortunately there are CA certificates out from before this RFC and the might contain negative serial numbers. One we encountered several times while testing is: commonName = EC-ACC organizationalUnitName = Jerarquia Entitats de Certificacio Catalanes organizationalUnitName = Vegeu https://www.catcert.net/verarrel (c)03 organizationalUnitName = Serveis Publics de Certificacio organizationName = Agencia Catalana de Certificacio (NIF Q-0801176-I) countryName = ES Our underlying library we use for handling certificates announced to no longer support certificates with negative serial numbers in one of the next versions. Therefore we decided to ignore certificates with negative serial numbers so we can update this library during the lifetime of this Checkmk release without changing this behaviour. Since the mentioned `EC-ACC` certificate was encountered multiple times during testing and is not widely used the fact that this certificate was encountered and is ignored is NOT logged. If you use certificates issued by CA certificates with negative serial numbers you can add them manually to your list of trusted certificates via the UI. This might cause warnings appearing in console outputs and in logfiles and may stop to work in the future.

[2.4.0] Checkmk Werk 16410 created: omd update: Fix Aborting in Docker Container

by Checkmk werks level 1

[//]: # (werk v2) # omd update: Fix Aborting in Docker Container key | value ---------- | --- date | 2024-03-12T15:30:46+00:00 version | 2.4.0b1 class | fix edition | cre component | omd level | 1 compatible | yes This bug affects users of the 2.3.0 beta. In Werk #16408 a mechanism was introduced to restore a site after an aborted update. If this mechanism triggered inside a docker container, then the site may be in an inconsistent state. Any further update will show the following error. ``` FileNotFoundError: [Errno 2] No such file or directory: '/omd/versions/2.3.0b1.cee/share/omd/skel.permissions' ``` You can check whether you are affected by this issue by comparing the output of `omd update` and `cat "${OMD_ROOT}"/.version_meta/version`. If the versions do not match, then you are affected by this issue. This Werk fixes the update procedure. In case you are affected, you can delete `.version_meta` and upgrade to the version which is shown by `omd update`.

From now on the plugin will use 'VirtualSize' if available, and 'Size' if not.
