- Checked every month or at least every quarter
Service level objective 2: 95% of push manifest or tag operations will complete in less than 3s
- Service level indicator 1: measured by DC, and will only take in account active DC for measurements [graph link]
- Checked every quarter/ month
Service level objective 3: registry is serving content (at least in read-only mode, pulling images) 99% of the time
- Service level indicator 1: 5XX responses over 2XX ratio is less than 1%
- Checked every quarter or month.
