Check Metrics

Metrics for Dash0 synthetic check evaluations.

dash0.check.enablement_conditions.value

Encodes whether a check's enablement condition passed.

PropertyValue
InstrumentGauge
Unit1
StabilityStable

Emitted by the check evaluation pipeline (scope dash0-issue-metrics). The value is 1 when the condition passed and 0 when it failed.

When a check rule has multiple enablement conditions, one data point is emitted per condition. The dash0.enablement_condition.index attribute (1-based: 1, 2, 3, …) identifies which condition the data point relates to.

Deprecated PromQL alias: dash0_check_enablement_conditions_value. Attributes:

KeyStabilityRequirement LevelValue TypeDescriptionExample Values
dash0.enablement_condition.indexStableRequiredint1-based index of the enablement condition within a check rule. [1]1; 2; 3

[1] dash0.enablement_condition.index: When a check rule has multiple enablement conditions, each condition emits its own data point on dash0.check.enablement_conditions.value, distinguished by this attribute (1, 2, 3, …).

dash0.check.evaluation.outcome

Encodes the outcome of check evaluations as an enum.

PropertyValue
InstrumentGauge
Unit{enum}
StabilityStable

Emitted by the check evaluation pipeline (scope dash0-issue-metrics). Encodes the immediate result of each evaluation cycle, before grace-period logic is applied. Unlike dash0.check.status, this metric has no pending state.

ValueNameDescription
-InfinactiveEnablement conditions were not met; the evaluation did not run.
0healthyThe evaluation result did not exceed any threshold.
1degradedThe result exceeded the degraded threshold but not the critical threshold.
2criticalThe result exceeded the critical threshold.

Deprecated PromQL alias: dash0_check_evaluation_outcome.

dash0.check.evaluation.value

The value returned by a check evaluation.

StabilityStable

Emitted by the check evaluation pipeline (scope dash0-issue-metrics).

Deprecated PromQL alias: dash0_check_evaluation_value.

dash0.check.status

Encodes the current state of a check as an enum.

PropertyValue
InstrumentGauge
Unit{enum}
StabilityStable

Emitted by the check evaluation pipeline (scope dash0-issue-metrics). The check's overall state after grace-period logic has been applied.

ValueNameDescription
-InfinactiveThe check is inactive (enablement conditions not met, or the check is disabled).
0healthyThe check is passing; no thresholds have been exceeded.
0.5pendingWithin the trigger grace period — the threshold has been exceeded but not long enough to transition to degraded or critical.
1degradedThe check has exceeded the degraded threshold and the grace period has elapsed.
2criticalThe check has exceeded the critical threshold and the grace period has elapsed.

Deprecated PromQL alias: dash0_check_status.

dash0.check.threshold.critical

Represents the critical threshold configured for a check rule.

PropertyValue
InstrumentGauge
Unit1
StabilityStable

Emitted by the check evaluation pipeline (scope dash0-issue-metrics). The value mirrors the critical threshold setting of the check rule, allowing dashboards and queries to compare the evaluation value against its threshold.

Deprecated PromQL alias: dash0_check_threshold_critical.

dash0.check.threshold.degraded

Represents the degraded threshold configured for a check rule.

View the dash0.check.threshold.degraded metric in Dash0

PropertyValue
InstrumentGauge
Unit1
StabilityStable

Emitted by the check evaluation pipeline (scope dash0-issue-metrics). The value mirrors the degraded threshold setting of the check rule, allowing dashboards and queries to compare the evaluation value against its threshold.

Deprecated PromQL alias: dash0_check_threshold_degraded.
