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
For RC monitoring
- 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.
- ROC_OPERATORS for the definition of the metrics that can generate a operations dashboard alarm when failing
- 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.
For operations tools monitoring
- OPS_MONITOR (monitoring of EGI.eu central tools including NGI SAM)
Others
- GLEXEC - gLExec tests
MyEGI
NCG
ATP
User guides
- MyEGI, Nagios, POEM
- SAM-PI documentation (Non official wiki page containing SAM PI examples)
Administrator guides
- SAM Release Notes
- SAM (including configuration via YAIM)
- SAM/NAGIOS Reference Card for sitemanger
- VO SAM
- Monitoring uncertified sites:
- Setting NAGIOS to Monitor Uncertified Sites
- IMPORTANT. EGI.eu provides catch-all WMS and BDII services for the monitoring of uncertified sites. The service is open for use, and your NGI can easily apply here.
