The FLAME Monitoring System involves computation modules, network link status monitoring, log tracking, parameter visualization, automatic alerts, and state control. It uses XML configuration files to manage system states and actions. Agents, manager, and console form the system structure, interfacing with devices and controlling critical metrics. SNMP and HTTP protocols are utilized.

The FLAME Monitoring System Functions: • computation modules monitoring (CM); • monitoring of the status of the system network’s links (for SCI); • monitoring of logs of CM serial consoles; • visualization of controlled parameters (metrics); • automatic response to critical values of metrics (active monitoring); • CM state control by means of the service network.
FLAME: Monitoring Scheme Configuration file: • has an XML format; • contains the description of the functions and intervals of computation reiteration; • assigns the structure of the XML files being composed and containing requested data. The state of the whole system equals the result of computation of a given set of functions, each depending on a set of measurable values of controlled devices. Sample function: the AND function of all system nodes.
FLAME: Monitoring System Structure (1/2) Agents: • interact directly with the OS and the equipment, • can be launched on demand, • collect and transmit data to the manager. The Manager: • supports the dynamic database (metrics repository), • collects, processes, and cashes data, • transmits data to the console, • controls the state of CM through the service network, • automatically reacts to critical values of metrics.
FLAME: Monitoring System Structure (2/2) The Console: • is a visualization and management tool, • queries the manager for the visualization data, • transmits CM control parameters to the manager, • grants the serial console for interactions with CM. The interaction protocol used are SNMP and HTTP.
