It was decided that the best course of action is to create a new plugin that would be able to utilise full feature set of Ceph dashboard modules RESTfull API. The existing plugin would get depricated together with Ceph restful module. Allowing users of newer ceph versions to monitor their setup with the capable dashboard module, but users of older ceph versions could continue using the restful module.

Ceph plugin for Zabbix Agent 2 uses deprecated RESTful API Ceph MGR module

Ceph plugin for Zabbix Agent 2 uses deprecated RESTful API Ceph MGR module which causes memory leaks in Ceph MGR due to the known bug in Ceph.

Ceph developers are going to mark the Ceph MGR module RESTful API as deprecated in the near future: https://github.com/ceph/ceph/pull/54984#issuecomment-1868867158

Also they encourage users to switch to the new ceph_api, which is provided by the Ceph Dashboard module.

So, for the Ceph plugin to work in the future, it should use the new api.
