The legacy http monitoring plugin caused quite some trouble over the last years. This included lots of effort to add features or just simply fixing bugs.

With the new plugin, the functionality is moved to maintainable and extendable code completely under control of Checkmk. This means also breaking changes with the old plugin:

  • Some metrics are not available anymore as it has been known. We discovered that these are simply not directly understandable. Instead we will add metrics as needed in the future. Some metrics will already be added in this first release
  • Some functionality has been a workaround and is now implemented directly into the new plugin. This makes it hard to migrate rules automatically.
  • Users are now able to decide on their own which functionality should be in an own service. This means, that it is now possible to test the certificate validity and response times in one service, if needed.
  • User are able to configure multiple http checks within one rule. You can provide standard settings to be used for all endpoints, and overwrite them per entry for each endpoint. Migrating manually makes absolute sense here.

Please note that we will not remove the old plugin for now. We understand that you need some time to migrate your configurations. Nethertheless, we will deprecate the old plugin and eventually remove it from Checkmk.
