[2.3.0] Checkmk Werk 16059 created: Fix possible failed notifications running in docker environment

by Checkmk werks level 1

Title: Fix possible failed notifications running in docker environment Class: fix Compatible: compat Component: notifications Date: 1695386294 Edition: cre Knowledge: doc Level: 1 Version: 2.3.0b1 Werk #15941 already fixed failed notifications on appliances if one recipient had no Email address configured. We have now seen the same behaviour when running Checkmk in a docker container because Nullmailer can not handle such recipients.

[2.3.0] Checkmk Werk 16081 created: Analyze configuration: false positive in "Restricted address mismatch" test

by Checkmk werks level 1

Title: Analyze configuration: false positive in "Restricted address mismatch" test Class: fix Compatible: compat Component: wato Date: 1695721351 Edition: cre Knowledge: doc Level: 1 State: unknown Version: 2.3.0b1 The "Restricted address mismatch" accidentally triggered a warning even if the corresponding "State in case of restricted address mismatch" entry of the "Checkmk Agent installation auditing" rule was left unconfigured. Additionally to the fix, this configuration test now also allows a <tt>CRIT</tt> state instead of the default <tt>WARN</tt>.

[2.3.0] Checkmk Werk 16136 created: api-docs: include explanation of the special character * for the If-Match header

by Checkmk werks level 1

This werk adds a short explanation to the api-docs so that our users know that this is possible.

[2.1.0] Checkmk Werk 15774 created: checking: Prevent data loss on hosts with longer check intervals

by Checkmk werks level 1

Title: checking: Prevent data loss on hosts with longer check intervals Class: fix Compatible: compat Component: core Date: 1695217743 Edition: cre Knowledge: doc Level: 1 Version: 2.1.0p34 Previously, the validity of agent data for discovery and HW/SW inventory checks was 2 minutes. When checking is performed with a longer interval, the discovery would re-trigger fetching of the agent data. In some checks this leads to data loss, because the checking fetches the data again and the data fetched by the discovery is lost. The cache interval for discovery and HW/SW inventory checks is now 1.5 * checking interval.

[2.3.0] Checkmk Werk 16135 created: apache_processes: we now replicate the configuration on remote sites

by Checkmk werks level 1

Title: apache_processes: we now replicate the configuration on remote sites Class: fix Compatible: compat Component: wato Date: 1695714746 Edition: cre Knowledge: doc Level: 1 Version: 2.3.0b1 This werk addresses an issue where we weren't replicating the configuration for the number of apache processes. Now we do. On activate changes the number of apache processes configured on the main site will now be replicated on the remote site. An apache restart is required for these changes to take effect.

[2.3.0] Checkmk Werk 16080 created: mssql_datafiles/transactionlogs: Regression in maximum size calculation

by Checkmk werks level 1

Title: mssql_datafiles/transactionlogs: Regression in maximum size calculation Class: fix Compatible: compat Component: checks Date: 1694589964 Edition: cre Knowledge: doc Level: 1 Version: 2.3.0b1 This is a follow-up to Werk #14421. Since Checkmk 2.1.0p5, we calculate the maximum size as the sum of available and used size for unlimited instances. However, in some cases, we accidentally drop explicit thresholds for the maximum size if avaiable, falling back to the unlimited case.

[2.2.0] Checkmk Werk 15815 created: LDAP connection ids that are invalid user ids will no longer crash Checkmk

by Checkmk werks level 1

Title: LDAP connection ids that are invalid user ids will no longer crash Checkmk Class: fix Compatible: compat Component: wato Date: 1686117166 Edition: cre Knowledge: doc Level: 1 State: unknown Version: 2.2.0p11 LDAP connection names have have stricter requirements in Checkmk version 2.2.0. Up until now, Checkmk did not check these requirements when creating new LDAP connections nor did an update convert them to fit the new requirements. This Werk tightens LDAP connection id validation to fit the new requirements. Updating Checkmk will cause all spaces in connection ids to be replaced with underscores, as this is the most common manifestation of this incompetability. If you still are unable to update, please check if your connection id consist only of letters and dashes, starting with a letter.

[2.2.0] Checkmk Werk 15643 created: nvidia_smi: Show Use full PCI bus ID

by Checkmk werks level 1

Title: nvidia_smi: Show Use full PCI bus ID Class: fix Compatible: incomp Component: checks Date: 1695304807 Edition: cre Knowledge: doc Level: 1 State: unknown Version: 2.2.0p11 This change affects users of the following checks: * nvidia_smi_memory_util * nvidia_smi_gpu_util * nvidia_smi_en_de_coder_util * nvidia_smi_power * nvidia_smi_temperature Previously, the PCI bus ID of NVIDIA GPUs would be incorrectly removed. This caused GPUs to be omitted, which should have been discovered. With this Werk, the full PCI bus ID is used as a service item. Users must rediscover the services.

[2.1.0] Checkmk Werk 15772 deleted: checking: fix cache validity of piggyback sections

by Checkmk werks level 1

Werk 15772 was deleted. The following Werk is no longer relevant. Title: checking: fix cache validity of piggyback sections Class: fix Compatible: compat Component: checks Date: 1694192952 Edition: cre Knowledge: doc Level: 1 Version: 2.1.0p34 Previously, piggyback sections had a cache validitiy of 90 seconds if checking was called from Checkmk and (checking interval * 1.5) seconds if called from the command line. This led to services in piggyback hosts becoming stale if checking interval of a source host was bigger than 1 minute. Cache validity is now (checking interval * 1.5) in both cases.
