InfluxDB -- influxQL的模糊查询

influxQL查询measurement中的指标时，可使用模糊查询。

查询measurement中字段包含特定字符串：

select * from cpu_used_percent where endpoint=~/192.168.0.1/ and time > '2021-09-11T00:00:00Z' order by time desc limit 10;

查询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;

查询meaurement中字段以某个字符串结束：

select * from cpu_used_percent where endpoint=~/vm-$/ and time > '2021-09-11T00:00:00Z' order by time desc limit 10;

//查询以Datacenter开头、vm-40结束的时序数据
select * from cpu_used_percent where endpoint=~/^Datacenter.*vm-40$/ order by time desc limit 10;
