Convert an SLA uptime percentage into allowed downtime per year, month and day — for any value like 99.97%.

Measure your SLI against an SLO target, see the error budget in % and events, and the downtime it allows.

See how much of your error budget is left for an SLO and period, with a suggested operating action.

Calculate error rate and success rate from request counts, and see the equivalent reliability in “nines”.

Convert any uptime % (like 99.9%) into allowed downtime per day, week, month or year — with a full nines table.

Calculate Mean Time To Recovery, Mean Time Between Failures, and the availability they imply.

Compute how fast you are consuming your error budget and whether it will run out before the window ends.
