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 tool instances
Documentation
- SAM Release Notes
- SAM Administrator's Guide
- SAM Probes
- Probes for the detection of unsupported gLite 3.1/3.2 products or end-points in GOCDB associated to retired service types
- SAM/NAGIOS Reference Card for sitemanger
- User Guides (Nagios, MyEGI, POEM)
- FAQs
- Troubleshooting
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.
Tests and probes
- SAM Tests terminology and types
- Probe development policy
- SAM released probes
- EGI probes for software version monitoring
- EMI Nagios and status (ARC, dCache, gLite, UNICORE)
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.
