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).

SAM profiles

Resource Centre AVAILABILITY/RELIABILITY COMPUTATION

  • ROC_CRITICAL - the profile for Availability/Reliability computation of EGI Resource Centres (OPS VO). It replaces WLCG_CREAM_LCGCE_CRITICAL as of 01 Jan 2012.

FOR GENERATION OF ALARMS IN THE OPERATIONS DASHBOARD IN CASE OF FAILURE

ALL METRICS THAT NCG CAN USE TO CONFIGURE A SAM NGI

  • ROC - all the possible metrics that NCG can use to configure NGI Nagios.

NOTE WELL: starting from SAMUpdate-17 the removal of a metric from ROC profile will immediately cause the removal of the metric from all NGI Nagios instances, i.e. tests will no longer be executed.
