> 70 and disk_total{app="clickhouse"}/1024/1024/1024 < 500 磁盘利用率大于70%就告警，对于盘不大的情况是适用的，如果盘太大，比如16T一块盘，使用 率70%还有非常大的余量，所以这里我们使用and附加一个条件，限制一下disk_total，即磁盘 总大小，磁盘总大小小于500GB，才适用磁盘利用率大于70%这个规则。 or vector1 举个例子，还是磁盘利用率的问题，对于超过1个T的大盘，剩余量小于300G就告警，promql 怎么写？ disk_free{app="clickhouse"}/1024/1024/1024 < 300 unless disk_total{app="clickhouse"}/1024/1024/1024 < 1024 使用 unless 排除掉小于1个T的盘，剩下的就只剩大于1个T的大盘了，效果达成。 向量匹配
