Overview

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 be good_service / total_service over any queried time interval. The value of performance always falls into the range 0 <= performance <= 1. A custom SLI describes how to compute this ratio, whether this is by dividing values from a pair of time series, cutting a Distribution into 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.

#basic_sli ⇒ ::Google::Cloud::Monitoring::V3::BasicSli

Returns Basic SLI on a well-known service type.

Note: The following fields are mutually exclusive: basic_sli, request_based, windows_based. If a field in that set is populated, all other fields in the set will automatically be cleared.

Returns:

  • (::Google::Cloud::Monitoring::V3::BasicSli) —

    Basic SLI on a well-known service type.

    Note: The following fields are mutually exclusive: basic_sli, request_based, windows_based. If a field in that set is populated, all other fields in the set will automatically be cleared.

#request_based ⇒ ::Google::Cloud::Monitoring::V3::RequestBasedSli

Returns Request-based SLIs

Note: The following fields are mutually exclusive: request_based, basic_sli, windows_based. If a field in that set is populated, all other fields in the set will automatically be cleared.

Returns:

  • (::Google::Cloud::Monitoring::V3::RequestBasedSli) —

#windows_based ⇒ ::Google::Cloud::Monitoring::V3::WindowsBasedSli

Returns Windows-based SLIs

Note: The following fields are mutually exclusive: windows_based, basic_sli, request_based. If a field in that set is populated, all other fields in the set will automatically be cleared.

Returns:
