关于influxdb:InfluxDB-influxQL的模糊查询

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;
