Current status of regionalization
Nagios/SAM provides regionalized version which is synchronized with the central instance. SAM/Nagios releases follow EGI software release process. List of NGI instances can be found on the following page: SAM Instances.
ATPs at NGI instances are independent from the central one, meaning that they perform synchronization with information sources directly. NGI instance could in theory point ATP to different information sources (e.g. alternative VO feeds).
Use cases
Use case #1
Monitor sites and service not in central gocdb.
Use case description
NGIs could need to monitor sites not in the central gocdb, test sites or sites not in EGI because founded separately.
Dependencies with other regionalized tools
regionalized GOCDB, custom ATP
Regionalized ATP
- SAM Team states: ATPs instances at NGI are independent from the central one, meaning that they perform synchronization with information sources directly. NGI instance could in theory point ATP to different information sources (e.g. alternative VO feeds).
- The ATP authoritative sources of information are the following:
- GOCDB for EGEE sites, services and downtimes.
- RSV for OSG sites, services and downtimes.
- The CIC Portal for the list of VOs.
- The experiment VO feeds (see below) to define which are the services (among the ones defined by GOCDB and RSV) that they support.
- The BDII for any other VO, to define mapping between services and VOs supported.
- The MoU portal, to define the WLCG Site-Tier mapping.
- The GridMap interface, to extract CPU counts
Can all of these information source be all regionalized instances?
Use case #2
Add custom probes
Use case description
NGIs may want to deploy custom probes in their regional Nagioses. To monitor with VO-specific probes, or with tighter thresolds..
Dependencies with other regionalized tools
- MDDB-POEM
- POEM, the successor of Metric Description DataBase is still under developement. A regional instance of POEM is planned in the development plan.
- ATP
