Remaining error budget as a fraction of the original budget.

1.0 means the budget is fully intact and 0.0 means it is fully exhausted. The range is (-inf, 1]: only the upper bound is clamped, so an over-budget SLO reads negative and a burndown chart can render the breach below the axis. A value at or below zero means the budget is exhausted and the SLO is in violation; the magnitude says by how much. Attributes:

Value is the ratio of the observed failure rate in the window (1 minus the success ratio) to the allowed budget fraction (1 minus the target). A value of 1.0 means the budget is being consumed at exactly the allowed rate; a value of 14.4 means it is being consumed 14.4x faster than allowed. Attributes:

Google SRE multi-window multi-burn-rate, fast tier, pre-composed so an alert can target one series instead of writing the AND of two windows. Value is 1 when a short and long window both exceed the tier threshold, otherwise 0. Examples for a 28 day window SLO: dash0.slo.burn_rate.5min >= 13.4 AND dash0.slo.burn_rate.1h >= 13.4 dash0.slo.burn_rate.30min >= 5.6 AND dash0.slo.burn_rate.6h >= 5.6 Attributes:
