Adjust your SLO

See how to adjust your SLI metrics leveraging SLI analyzer.

• Once you've determined the right target using your existing data, build an SLO using those parameters that make sense for your business.

To do so, follow these steps:

1. Open the already created analysis that is in the Analysis complete status.

   caution

   You can't create an SLO from an analysis that has no data available. Create a new analysis and select a different graph time window to get the analysis results and create an SLO.

2. Click Create SLO.

3. The SLO wizard is displayed. Select the following:

   • In step 1, select a Service from the drop-down list that this SLO applies to.

   • In step 2, the Data Source and the Metric settings are prefilled with the values selected in the analysis.

   • In step 3, define a Time Window, that is, choose a Rolling or Calendar-Aligned Time Window.

   • In step 4, the Error Budget Calculation Method, Target, Values are populated from the analysis as a first objective in the SLO.

     • You must provide unique SLO objective's Name.

   • In step 5 of the SLO wizard, you must define the SLO Name and other SLO attributes.
     

     note

     Nobl9 automatically adds a link in the SLO to the SLI analysis.

   • Click Create SLO.

You can also create an SLO from an analysis through sloctl by applying an automatically generated YAML configuration. Click View YAML, replace the SLO_NAME and SERVICE_NAME placeholders with the actual names of your SLO and service, and apply that YAML through sloctl. For more information, refer to the SLI analyzer documentation.

Statistical data

Besides computing your actual SLO status with the configured metric and time window settings, SLI analyzer provides you with additional statistical data.

These numbers can additionally help you better understand the performance of your service:

Besides the above-mentioned statistical data, you can also see percentiles. These include:

• For the Values field operators ≥ or > , p1, p5, p10, and p50 are displayed:
• For the Values field operators ≤ or <, p50, p90, p95, p99 and p99.9 are displayed:
