[2.3.0] Checkmk Werk 16762 created: check certificates: fix signature algorithm configuration

by Checkmk werks level 1

[//]: # (werk v2) # check certificates: fix signature algorithm configuration key | value ---------- | --- date | 2024-04-24T06:54:32+00:00 version | 2.3.0b7 class | fix edition | cre component | checks level | 1 compatible | no Upgrading from 2.3.0b4 to a later version could cause the _Check Certificates_ settings for signature algorithms to load incorrectly due to missing choices in the old settings. This werk ensures correct loading. This work is incompatible because some old algorithms are no longer available. Old configurations are converted as follows: ## rsa - sha224: RSA_WITH_SHA224 - sha256: RSA_WITH_SHA256 - sha384: RSA_WITH_SHA384 - sha512: RSA_WITH_SHA512 - sha3_224: RSA_WITH_SHA224 - sha3_256: RSA_WITH_SHA256 - sha3_384: RSA_WITH_SHA384 - sha3_512: RSA_WITH_SHA512 ## ecdsa - sha224: ECDSA_WITH_SHA224 - sha256: ECDSA_WITH_SHA256 - sha384: ECDSA_WITH_SHA384 - sha512: ECDSA_WITH_SHA512 - sha3_224: ECDSA_WITH_SHA224 - sha3_256: ECDSA_WITH_SHA256 - sha3_384: ECDSA_WITH_SHA384 - sha3_512: ECDSA_WITH_SHA512 ## rsassa_pss Everything to RSASSA_PSS ## ed25519 ED25519 ## dsa - sha224: DSA_WITH_SHA224 - sha256: DSA_WITH_SHA256 - sha384: DSA_WITH_SHA256 - sha512: DSA_WITH_SHA256 - sha3_224: DSA_WITH_SHA224 - sha3_256: DSA_WITH_SHA256 - sha3_384: DSA_WITH_SHA256 - sha3_512: DSA_WITH_SHA256

[2.3.0] Checkmk Werk 14230 created: BI: Fixed incorrect aggregation of downtimes

[//]: # (werk v2) # BI: Fixed incorrect aggregation of downtimes key | value ---------- | --- date | 2024-04-10T12:05:48+00:00 version | 2.3.0b6 class | fix edition | cre component | bi level | 1 compatible | yes The configuration option <tt>Escalate downtimes based on aggregated WARN state</tt> did not correctly since version 1.5.

[2.3.0] Checkmk Werk 14229 created: Valuespecs: Fixed confusion of values when ListOf contains another ListOf and all have the same magic

by Checkmk werks level 1

[//]: # (werk v2) # Valuespecs: Fixed confusion of values when ListOf contains another ListOf and all have the same magic key | value ---------- | --- date | 2024-04-10T09:56:58+00:00 version | 2.3.0b6 class | fix edition | cre component | wato level | 1 compatible | yes Normally, ListOf elements embedded in other ListOf elements should contain a different magic value, otherwise errors will occur when processing forms. This werk here allows the use of identical magic values.

[2.3.0] Checkmk Werk 15843 adapted: mk_oracle(ps1): Follow-up to privilege escalation fix

by Checkmk werks level 1

Werk 15843 was adapted. The following is the new Werk, a diff is shown at the end of the message. [//]: # (werk v2) # mk_oracle(ps1): Follow-up to privilege escalation fix key | value ---------- | --- compatible | no version | 2.3.0b4 date | 2024-04-05T11:02:27+00:00 level | 2 class | fix component | checks edition | cre You might be affected by this Werk if you use <tt>mk_oracle</tt> on Windows. Werk <a href="https://checkmk.com/werk/16232">Werk #16232</a> introduced a regression, thereby disrupting Oracle monitoring on Windows. This Werk addresses above mentioned issue that affects versions 2.1.0p41, 2.2.0p24, and 2.3.0b4. Since this release, Oracle monitoring on Windows is fully supported under either of the following conditions: 1. The monitoring is performed using an account without administrator rights. 2. Specific Oracle executable binaries — namely, <tt>sqlplus.exe</tt>, <tt>tnsping.exe</tt> and, if presented, <tt>crsctl.exe</tt> - are not modifiable by non-admin users. If you are still unable to monitor Oracle, for example, you can't use an unprivileged account for monitoring and changing of permission is not possible, consider one of the following actions: 1. Enable <tt>Run as local group</tt> for group <tt>Administrators</tt> in <tt>Run plugins and local checks using non-system account</tt> ruleset. 2.

[2.3.0] Checkmk Werk 15845 created: winperf_if check correctly discovers and processes interfaces with spaces

by Checkmk werks level 1

[//]: # (werk v2) # winperf_if check correctly discovers and processes interfaces with spaces key | value ---------- | --- date | 2024-04-22T15:31:08+00:00 version | 2.3.0b7 class | fix edition | cee component | checks level | 1 compatible | no Previously, some Windows network interface names with additional spaces — particularly before the hash symbol — were not recognized by the check engine. This led to the absence of some services, especially Windows teaming network interfaces. In this release, such interface names are handled correctly thus fixing the problem. Still, you may need to rediscover services again.

[2.3.0] Checkmk Werk 16736 created: Warn during update if contact groups are used in rulesets but not available

by Checkmk werks level 1

[//]: # (werk v2) # Warn during update if contact groups are used in rulesets but not available key | value ---------- | --- date | 2024-04-23T07:42:11+00:00 version | 2.3.0b6 class | fix edition | cme component | wato level | 1 compatible | yes Some rulesets like 'Assignment of hosts (or services) to contact groups' use contact groups which may not be synced because they are assigned to a specific customer or to 'Provider' (default). This inconsistency might have already been present in your configuration but went unnoticed in the previous versions. With 2.3, we introduced new validation mechanics which now warn you about this potential issue. With this change we make the shown error message a more helpful so that users get a hint how to solve the situation.

[2.3.0] Checkmk Werk 16756 created: host_config: introduce include_links option for Show all hosts endpoint

by Checkmk werks level 1

[//]: # (werk v2) # host_config: introduce include_links option for Show all hosts endpoint key | value ---------- | --- date | 2024-04-23T06:37:18+00:00 version | 2.3.0b6 class | feature edition | cre component | rest-api level | 1 compatible | no This werk introduces the flag 'include_links' for the 'Show all hosts' host config endpoint. It toggles whether the links field should be populated of the individual hosts. This serves as a mechanism to reduce the payload generated. This field defaults to False and existing scripts therefore have to be adjusted accordingly.
