Inventory objects form a hierarchy with Node at the top, then Service and Agents assigned to a Node.

There are three tabs where items for each type are listed with their details:

  • Services

    Individual service names and where they run, against which agents will be assigned. Each instance of a service gets a service_id value that is related to a node_id. Examples are MySQL, Amazon Aurora MySQL. This feature also allows to support multiple mysqld instances on a single node, with different service names, e.g. mysql1-3306, and mysql1-3307.

  • Agents

    Each binary (exporter, agent) running on a client will get an agent_id value. Examples:

    • pmm-agent one is the top of the tree, assigned to a node_id
    • node_exporter is assigned to pmm-agent agent_id
    • mysqld_exporter and QAN MySQL Perfschema are assigned to a service_id.

  • Nodes

    Where the service and agents will run. Assigned a node_id, associated with a machine_id (from /etc/machine-id). Some examples are bare metal, virtualized, container.
