CreateServiceLevelObjective

Creates a service level objective (SLO), which can help you ensure that your critical business operations are meeting customer expectations. Use SLOs to set and track specific target levels for the reliability and availability of your applications and services. SLOs use service level indicators (SLIs) to calculate whether the application is performing at the level that you want.

Create an SLO to set a target for a service or operation’s availability or latency. CloudWatch measures this target frequently you can find whether it has been breached.

When you create an SLO, you set an attainment goal for it. An attainment goal is the ratio of good periods that meet the threshold requirements to the total periods within the interval. For example, an attainment goal of 99.9% means that within your interval, you are targeting 99.9% of the periods to be in healthy state.

After you have created an SLO, you can retrieve error budget reports for it. An error budget is the number of periods or amount of time that your service can accumulate during an interval before your overall SLO budget health is breached and the SLO is considered to be unmet. for example, an SLO with a threshold that 99.95% of requests must be completed under 2000ms every month translates to an error budget of 21.9 minutes of downtime per month.

When you call this operation, Application Signals creates the AWSServiceRoleForCloudWatchApplicationSignals service-linked role, if it doesn't already exist in your account. This service- linked role has the following permissions:

You can easily set SLO targets for your applications that are discovered by Application Signals, using critical metrics such as latency and availability. You can also set SLOs against any CloudWatch metric or math expression that produces a time series.

For more information about SLOs, see Service level objectives (SLOs).
