Reference documentation and code samples for the Stackdriver Monitoring V3 Client class ServiceLevelIndicator.
A Service-Level Indicator (SLI) describes the "performance" of a service. For
some services, the SLI is well-defined. In such cases, the SLI can be
described easily by referencing the well-known SLI and providing the needed
parameters. Alternatively, a "custom" SLI can be defined with a query to the
underlying metric store. An SLI is defined to begood_service /
total_serviceover any queried time interval. The value of performance
always falls into the range0 <= performance <= 1. A custom SLI describes
how to compute this ratio, whether this is by dividing values from a pair of
time series, cutting aDistributioninto good and bad counts, or counting
time windows in which the service complies with a criterion. For separation
of concerns, a single Service-Level Indicator measures performance for only
one aspect of service quality, such as fraction of successful queries or
fast-enough queries.
