The Service Availability Monitoring (SAM) system is used to monitor the resources within the production infrastructure. SAM monitoring data is used for calculation of availability and reliability of grid sites. It includes the following components:
- probes: a test execution framework (based on the open source monitoring framework Nagios) and the Nagios Configuration Generator (NCG)
- the Aggregated Topology Provider (ATP), the Metrics Description Database (MDDB), and the Metrics Results Database (MRDB)
- the message bus to publish results and a programmatic interface
- the visualization portal (MyEGI).
