influxQL 查问 measurement 中的指标时，可应用含糊查问。
查问 measurement 中字段蕴含特定字符串：
select * from cpu_used_percent where endpoint=~/192.168.0.1/ and time > '2021-09-11T00:00:00Z' order by time desc limit 10;查问 measurement 中字段以某个字符串起始：
select * from cpu_used_percent where endpoint=~/^datacenter/ and time > '2021-09-11T00:00:00Z' order by time desc limit 10;查问 meaurement 中字段以某个字符串完结：
select * from cpu_used_percent where endpoint=~/vm-$/ and time > '2021-09-11T00:00:00Z' order by time desc limit 10;// 查问以 Datacenter 结尾、vm-40 完结的时序数据
select * from cpu_used_percent where endpoint=~/^Datacenter.*vm-40$/ order by time desc limit 10;
