[2.4.0] Checkmk Werk 15516 created: check_cert: New active check for advanced certificate monitoring

by Checkmk werks level 2

[//]: # (werk v2) # check_cert: New active check for advanced certificate monitoring key | value ---------- | --- date | 2024-04-03T13:42:35+00:00 version | 2.4.0b1 class | feature edition | cre component | checks level | 2 compatible | yes The _check_http_ plug-in was previously the only method to monitor certificates out-of-the-box with Checkmk.

With the new plug-in you can monitor all certificates provided through a TCP connection to encrypt communication. This includes the monitoring of * validity times (max and remaining) * issuer fields * subject fields * encryption algorithm * alternative names * response times * public key algorithm and size * serial number As with the reworked plugin to monitor web services, you are able to configure multiple services within a single rule.

[2.4.0] Checkmk Werk 15515 created: check_http: Soft deprecatation of old HTTP monitoring plug-in

by Checkmk werks level 2

[//]: # (werk v2) # check_http: Soft deprecatation of old HTTP monitoring plug-in key | value ---------- | --- date | 2024-04-03T13:15:48+00:00 version | 2.4.0b1 class | feature edition | cre component | checks level | 2 compatible | no The old plug-in is being deprecated in a soft way with this werk. Unlike hard deprecation, the deprecated rule set "Check HTTP service" will remain fully functional. However, new rules should only be created if absolutely necessary, such as when experiencing issues with the new "Check HTTP web service" implementation and needing to roll back to the old one. Please note that the rule set will be hard deprecated in version 2.4.0, meaning that you will no longer be able to create new rules. However, the plug-in itself will remain available as this is a component of the monitoring-plugins collection that comes with Checkmk. Please know us know if you find any features that were present in the old plug-in but are missing in the new one.
