Single View Creator Service

When working with Fast Data, you should already have one or more Single View Creator services, which will expose the relevant metrics. No additional configuration is needed.

Panels

The Dashboard contains the following panels, first depicted in sample screenshots, and later described in detail in the table below.

Panel NameDescription
Avg Processing Rate [SV/s]Average number of projection changes that are processed per second to generate Single Views (in the current time-frame)
Max Processing Rate [SV/s]Maximum number of projection changes that have been processed per second to generate Single Views in the current time-frame
Total # SV processedTotal amount of Projection Changes processed to generate Single Views in the current time-frame (approximated)
Total # SV Generation ErrorsTotal amount of errors encountered while generating Single Views in the current time-frame (approximated). Only events that are not ERROR_SEND_SVC_EVENT are counted
Total # Kafka Production ErrorsTotal amount of errors encountered while generating Single Views in the current time-frame (approximated). Only events equal to ERROR_SEND_SVC_EVENT are counted
SVC Processing RateProcessing Rate of projection changes for the creation of Single Views, grouped by Single View Type and Portfolio Origin
SVC Service ReplicasNumber of active replicas for Single View Creator services, grouped by deployment
SVC Validation ErrorShows the amount of validation errors obtained from generating Single Views in the time interval
SVC No Generation ErrorShows the amount of Single Views not generated in the time interval
SVC single PC to multiple SV ErrorShows the amount of errors due to a violation of the 1-to-1 relationship between a Projection Change and the generated Single Views in the time interval
SVC Max Aggregation Time ErrorShows the amount of max aggregation time errors (caused by exceeding allowed computation time) obtained from generating Single Views in the time interval
SVC Unknown ErrorShows the amount of unknown errors obtained from generating Single Views in the time interval
SVC Kafka Send ErrorShows the amount of errors obtained while sending messages to Kafka in the time interval
SVC Operation TypesShows how many operations are performed generating Single Views, grouped by Operation Type
SV Creation TimeShow the total amount of time spent creating Single Views
