当存在与另一组匹配器匹配的警报（源）时，禁止规则将匹配一组匹配器的警报（目标）静音。目标和源警报必须具有`equal`列表中标签名称的相同标签值。 从语义上讲，缺少标签和具有空值的标签是相同的。因此，如果`equal`源和目标警报中都缺少所列的所有标签名称，则将应用禁止规则。 为了防止提醒抑制本身，即相匹配的警报*既*目标和规则的源极侧不能由警报其中相同为真（包括其本身）的抑制。但是，我们建议以警报永远不会匹配双方的方式选择目标和源匹配器。理由更容易，并且不会触发这种特殊情况。 ~~~ # Matchers that have to be fulfilled in the alerts to be muted. target_match: [ <labelname>: <labelvalue>, ... ] target_match_re: [ <labelname>: <regex>, ... ] # Matchers for which one or more alerts have to exist for the # inhibition to take effect. source_match: [ <labelname>: <labelvalue>, ... ] source_match_re: [ <labelname>: <regex>, ... ] # Labels that must have an equal value in the source and target # alert for the inhibition to take effect.
