A Service-Level Objective (SLO) describes a level of
desired good service. It consists of a service-level indicator (SLI), a
performance goal, and a period over which the objective is to be
evaluated against that goal. The SLO can use SLIs defined in a number of
different manners. Typical SLOs might include “99% of requests in each
rolling week have latency below 200 milliseconds” or “99.5% of requests
in each calendar month return successfully.”
Name used for UI elements listing this SLO.
The fraction of service that must be good in order for this
objective to be met. 0 < goal <= 0.999.
A rolling time period, semantically “in the past
<rolling_period>”. Must be an integer multiple of 1 day no
larger than 30 days.
