The Server Density agent is delivered as an RPM package for current RHEL based distros including CentOS, CloudLinux, Oracle, Red Hat and Scientific Linux. The core agent is required for monitoring key metrics, with plugins installed as an additional package. The agent and plugins will be kept up to date in-line with your own policy (nightly, weekly, manually etc).

Automatic installation
You can install the agent automatically using our shell script, or with our Puppet, Chef, Ansible and Salt modules. See automatically scaling and deploying the agent.
Prerequisites
- A device created in your Server Density account (find out how to create a device in the UI)
- sudo (root access) is required but the agent runs as its own user (sd-agent) once installed.
- The agent requires sysstat to be installed to collect some key metrics. This will be installed as a dependency during installation.
