Checkmk Werk 14574: KUBE: Memory and CPU resources: allow setting higher levels on request utilization

by Solomon Jacobs

ID: 14574 Title: KUBE: Memory and CPU resources: allow setting higher levels on request utilization Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 Previously, the rules <tt>Kubernetes memory resource utilization</tt> and <tt>Kubernetes CPU resource utilization</tt> did not allow setting levels above 101.0%. This is a limitation since workloads above 100% are common in Kubernetes. With this werk, levels can be arbitrarily large.

Checkmk Werk 15110: Crash upon empty result of piggyback hostname translation

by Moritz Kiemer

ID: 15110 Title: Crash upon empty result of piggyback hostname translation Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 >From Checkmk version 2.1 the <i>Check_MK</i> service crashed if the settings in <i>Hostname translation for piggybacked hosts</i> resulted in an empty host name. The host name <tt>''</tt> is now replaced by <tt>'_'</tt>. This is consistent with other invalid host names (such as <tt>'../../bin/pwn'</tt>), where the invalid characters are replaced by an underscore.

Checkmk Werk 15045: MySQL Database monitoring under Windows: Support instance names containing spaces

Checkmk Werk 15171: Datadog special agent: Fix time shifts when querying logs

by Joerg Herbel

ID: 15171 Title: Datadog special agent: Fix time shifts when querying logs Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 When querying logs from the Datadog API, there was a shift in the time window of the query. The shift corresponded to the UTC offset of the local time zone of the monitoring server. This was caused by misinterpreting local times as UTC times. For example, if the local time zone of the monitoring server is CET, then there was a shift of one hour into the future, causing the agent to query future logs. If the local time zone of the monitoring server is UTC, there was no shift.

by Rebekka Seltmann

ID: 15201 Title: Remove ps output width limitation for several Checkmk agents Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 Currently the width of the output of the ps command for several Checkmk agents is limited to 10000 characters, causing pattern matching to fail for longer processes. The width is now no longer limited for the agents for the following operating systems: LI: Linux LI: FreeBSD LI: NetBSD LI: OpenBSD

Checkmk Werk 15206: DCD: resolve bug when hosts with locked attributes are included in Phase 2.2

by Wontek Hong

ID: 15206 Title: DCD: resolve bug when hosts with locked attributes are included in Phase 2.2 Component: Dynamic host configuration Level: 1 Class: Bug fix Version: 2.2.0i1 Prior to this werk, DCD was unable to complete Phase 2.2 whenever the REST API returned host configs which included locked attributes. This werk resolves this issue and no further KeyError should appear in the DCD logs. The bug was previously introduced with werk 13640.

Checkmk Werk 13258: Add failover information to NetApp interface checks

by Frans Fürst

ID: 13258 Title: Add failover information to NetApp interface checks Component: Checks & agents Level: 1 Class: New feature Version: 2.2.0i1 The NetApp plugin now processes ports (and their associated link-status) of monitored interfaces and takes provided failover information into account. If any of a given virtual interface failover ports is not 'up' the `netapp_api_if` check now returns CRIT if it's part of the home node, WARN otherwise.

Checkmk Werk 13265: netapp_api_if: discover interfaces even if they have no `recv_data` entry

by Frans Fürst

ID: 13265 Title: netapp_api_if: discover interfaces even if they have no `recv_data` entry Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 Discovery for `netapp_api_if` would skip interfaces with no entry for amount of received data (for historical) reasons. This change makes the discovery function discover even those interfaces without this information resulting in potentially more discovered items.
