[2.3.0] Checkmk Werk 17112 created: ICMP Echo Request (Ping): Off-by-one error in active check

by Checkmk werks level 1

[//]: # (werk v2) # ICMP Echo Request (Ping): Off-by-one error in active check key | value ---------- | --- date | 2024-06-26T08:50:24+00:00 version | 2.3.0p8 class | fix edition | cre component | checks level | 1 compatible | no This fixes a regression in Checkmk version 2.3. When using the setting _"Ping IP address identified by its index"_ of the plugin _ICMP Echo Request (Ping)_, the used address was off by one. The fix is incompatible for users that have accounted for this error and changed their rule. To avoid mistakes in the future, we've added a hint to the rule, and validate that the configured index is equal to or larger than 1.

[2.2.0] Checkmk Werk 17080 created: Hanging background jobs/frozen site

by Checkmk werks level 1

Title: Hanging background jobs/frozen site Class: fix Compatible: compat Component: multisite Date: 1719405900 Edition: cee Level: 1 Version: 2.2.0p28 Background jobs could previously hang without ever finishing under the wrong conditions. This could lead to the entire site freezing if the job had acquired crucial file locks (i.e. a lock on licensing files). This is usually accompanied by the error C+: Bad file descriptor C-: in the logs.

[2.2.0] Checkmk Werk 17075 created: Fix regex error when using global flags when matching multiple expressions

by Checkmk werks level 1

Title: Fix regex error when using global flags when matching multiple expressions Class: fix Compatible: compat Component: wato Date: 1718966795 Edition: cre Level: 1 Version: 2.2.0p28 There are a few places where we concatenate multiple regular expressions to save performance. This concatenation broke when expressions using global flags such as "(?i)cpu" were concatenated. With this werk, we are converting these global flags to local ones for that specific expression which restores the expected behavior of the expression, fixing various crashes that would occur for example when updating or activating changes.

[2.3.0] Checkmk Werk 16513 created: Add option to change the maximum response size for livestatus

by Checkmk werks level 1

[//]: # (werk v2) # Add option to change the maximum response size for livestatus key | value ---------- | --- date | 2024-06-26T11:51:44+00:00 version | 2.3.0p8 class | feature edition | cee component | core level | 1 compatible | yes We add a new option in WATO under General > Global settings > Monitoring core to set the maximum livestatus response time for CMC. Note, however, that setting this value too high may result in out-of-memory errors or timeout on the livestatus sockets. Use with care.
