Basic concepts

Complete configuration for all the agents is saved on the server (CMR) component of the inspectIT. The configuration is managed via the user interface Configuration Interface perspective.

Brief overview of the configuration elements

There are three main elements that are used to define the complete configuration:

...

Profiles can be used in many environments, while environments can include multiple profiles. This n:m relationships enables easy separation of the configuration and easier management. One environment can be assigned to one or more mappings. Thus, many agents can use the same environment easily. In addition, mappings enable easy switching of the environments for the agent. 

Process of applying configuration and instrumentation

When the agent is started, it reads the repository information and the agent name from the JVM parameters (see Installation Guide and Setting the repository and agent name via JVM parameters). The agent then tries to registers itself with the given repository. If the repository is available and registration is successful agent will receive the configuration from the server that includes basic options and active sensors with their properties. Note that registration will be successful only if there is exactly and only one environment mapped for this agent in the configuration interface. Any change in the configuration requires agent restart, so that updated configuration can be sent to the agent.
