SAM metric translated into SSB metric
SSB metric name : SAM metric name + FQANorg.atlas.SRM-VODel (_atlas_Role_production)
Instance : service flavour + hostnameSRMv2 srm-atlas.gridpp.rl.ac.ukCREAM-CE cream-ge-5-kit.gridka.de
Status OK, CRITICAL, WARNING, UNKNOWN
Color : mapping from Statusgreen, red, yellow, blue
URL to metric output, composed by hostname, timestamp and SAM metric name

Aggregation of SSB metrics
Two types: Horizontal: Ins1 (M1…Mn) Ins1 (Mp)
Aggregate SSB metrics into new metric (same instances)
Vertical: M1 (Ins1…Insn) Insp (M2) Aggregate SSB metric results for several instances
into metric result for one new instance
Operations over metric results “and” (R1…Rn) - worst status/color
“or” (R1…Rn) - best status/color

SSB View
Logically related metrics are combined into views Container for metrics
Doesn’t have its own data
Defined by a VO
VO can defined as many views as needed

How do we know how to aggregate?
Profile configuration Horizontal aggregation
algorithm * : “and” operation + : “or” operation
Vertical aggregation service_site_metric
Fed from VO feeds
Metric instances Service type flavour Metric name FQAN

How aggregation was done here?
SSB <VO>_topo metrics fed by VO feeds
Vertically by topology, applying ‘OR’ operation at the service flavour level
