Diamond Plugin was deprecated in Cloudify 5.0. It is no longer supported.
The Diamond plugin is used to install & configure a Diamond monitoring agent (version 3.5) on hosts.
Diamond is a Python daemon that collects system metrics and publishes them to multiple destinations. It can collect CPU, memory, network, I/O, load and disk metrics, and many other metrics, as specified in the documentation. Additionally, it features an API for implementing custom collectors for gathering metrics from almost any source.
