Functions

func AlertRuleGen 

func AlertRuleGen(mutators ...AlertRuleMutator) func() *AlertRule

AlertRuleGen provides a factory function that generates a random AlertRule. The mutators arguments allows changing fields of the resulting structure

func PatchPartialAlertRule 

func PatchPartialAlertRule(existingRule *AlertRule, ruleToPatch *AlertRuleWithOptionals)

There are several exceptions: 1. Following fields are not patched and therefore will be ignored: AlertRule.ID, AlertRule.OrgID, AlertRule.Updated, AlertRule.Version, AlertRule.UID, AlertRule.DashboardUID, AlertRule.PanelID, AlertRule.Annotations and AlertRule.Labels 2. There are fields that are patched together:

  • AlertRule.Condition and AlertRule.Data

If either of the pair is specified, neither is patched.
