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.

Introduction

SAM

SAM profiles

POEM (Profile Management Database, former Metric Description Database) aims to describe existing metrics and group (profiles) them in order to run tests. In addition it should define actions that can either configure the way the availability and reliability is computed or allow notifications to messaging system.

Profiles for RC monitoring

  • ROC - Tests for monitoring of all EGI services; applied on all NGI SAM Nagioses. 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.
  • ROC_CRITICAL - The profile for Availability/Reliability computation of EGI Resource Centres (OPS VO), subset of ROC tests. NOTE: It replaces WLCG_CREAM_LCGCE_CRITICAL as of 01 Jan 2012.
  • ROC_OPERATORS - Subset of ROC tests that are Operations tests, metrics that can generate an alarm on the operations dashboard when failing.
