[2.2.0] Checkmk Werk 16222 created: Automationuser login must not open full session

by Checkmk werks level 1

Title: Automationuser login must not open full session Class: fix Compatible: incomp Component: wato Date: 1700382222 Edition: cre Level: 1 Version: 2.2.0p16 Checkmk offers a method to authenticate single web requests with URL parameters (<tt>_username</tt> and <tt>_secret</tt>). Due to some refactoring of the session handling with Checkmk 2.2 such automation requests initiated a full session. The login for automation users was still blocked in the login screen but an authenticated request initiated a full session that could than be used to browse the Checkmk GUI like a regular user. With this Werk that is no longer the case. If you use this authentication method you should check if you rely on sessions for your automation users.

[2.3.0] Checkmk Werk 15646 created: KUBE: Extend `Node conditions` Rule

by Checkmk werks level 1

Title: KUBE: Extend `Node conditions` Rule Class: fix Compatible: incomp Component: checks Date: 1701104788 Edition: cre Knowledge: doc Level: 1 Version: 2.3.0b1 Previously, Checkmk identified any NodeCondition with status `True`, except for the `Ready` condition, as a problem state. However, some Kubernetes addons report custom NodeConditions. In some cases, the `True` status of these conditions is desired. With this Werk, this is fully configurable. Since there are no longer pre-defined problem states, the NodeConditions are now shown in the summary based on their monitoring states. The affected rule `Node conditions` has been renamed to `Kubernetes node conditions`. The default rules ensure that the monitoring states of existing services do not change. Existing rules are migrated. Manual intervention is only needed if there are multiple `Kubernetes node conditions` rules, which apply the to the same service. Previously, each NodeCondition would use the rule with a matching parameter. The new rule contains only a single parameter, thus only the first rule applies. Moreover, some minor tweaks have been done. * The check falsely reported `.status.message` to be `None`. The proper message is now shown. * NodeConditions are now shown in the order they are received from the Kubernetes API. * The check no longer shows `NodeConditionStatus.FALSE`, instead it now shows `False`. * The check is unaffected if one of the following conditions is missing: `Ready`, `MemoryPressure`, `PIDPressure`, `DiskPressure`. This should not affect the monitoring since the Kubernetes API server ensures that these conditions are always present.

[2.3.0] Checkmk Werk 16279 created: service_discovery: redirect response header incorrectly configured to an absolute URI

by Checkmk werks level 1

Title: service_discovery: redirect response header incorrectly configured to an absolute URI Class: fix Compatible: compat Component: rest-api Date: 1700141008 Edition: cre Level: 1 Version: 2.3.0b1 When calling the service discovery endpoint, the redirect response header 'location' was set to an absolute URI, when it should be a relative URI. This werk addresses this issue by setting the URI correctly in the redirect responses.

[2.1.0] Checkmk Werk 16262 created: Browsing man pages from command line

by Checkmk werks level 1

Title: Browsing man pages from command line Class: fix Compatible: compat Component: checks Date: 1701023104 Edition: cre Knowledge: undoc Level: 1 State: unknown Version: 2.1.0p37 Viewing a check plugins man page using <tt>cmk -M my_check</tt> left the terminal in a bad state. Browsing man pages using <tt>cmk -m</tt> did not work at all (still leaving the terminal in a bad state). This is fixed. After running the commands <tt>cmk -M my_check</tt> or <tt>cmk -m</tt> the tty was not properly restored. Affected users can fix their prompt running <tt>stty sane</tt> or <tt>restore</tt>.

[2.2.0] Checkmk Werk 16328 created: primekey_hsm_battery_voltage: Fixed parsing of section when battery voltage is not available

by Checkmk werks level 1

Title: primekey_hsm_battery_voltage: Fixed parsing of section when battery voltage is not available Class: fix Compatible: compat Component: checks Date: 1700831541 Edition: cre Level: 1 Version: 2.2.0p16 Sometimes the battery voltage was not available or it wasn't a number. That cause the parsing of the section to fail. This has now been fixed. In the case of voltage being: 'External Battery: absence", the check status will be OK and the summary will provide details that the battery is absent. If the voltage is not a number or is not absent, the voltage check will be skipped and the check result will the battery state.

[2.2.0] Checkmk Werk 15923 created: haproxy: Adapted HAproxy Server State and HAproxy Frontend State rules to be item specific

by Checkmk werks level 1

Title: haproxy: Adapted HAproxy Server State and HAproxy Frontend State rules to be item specific Class: fix Compatible: compat Component: wato Date: 1700826137 Edition: cre Level: 1 Version: 2.2.0p16 HAproxy Server State and HAproxy Frontend State were not configurable with regard to the service name. This means that the rules were applied to all services. This has now been adapted and the rules can be configured to apply to certain services only.
