InfluxDB 常用命令

查表:

http://192.168.0.200:8086/query?q=select+*+from+telegraf..cpu

http://192.168.0.200:8086/query?q=select+*+from+mydb..cpu

http://127.0.0.1:8086/query?chunked=true&db=&epoch=ns&q=show+databases

http://127.0.0.1:8086/query?chunked=true&db=mydb&epoch=ns&q=show+measurements

http://127.0.0.1:8086/query?q=select+count(*)+from+mydb..cpu

插入数据:

INSERT cpu,host=serverA,region=us_west value=0.64

INSERT cpu,tagid=A001,host=serverA,region=us_west valuef=0.64,valuei=5,valueb=false,values="abcd1235" 1544065069061293100

按时间段查询数据: 

select * from mydb..cpu where time>'2018-12-03 12:40:39' and time<'2018-12-03 12:40:41'

select * from mydb2018..unittest where tagId='t1' and  time>'2016-06-01 00:00:00' and time<'2016-06-01 00:01:00'

示例:

select * from TAGDATA where TAGCODE='MZY_KF1:12LI-111004L01C' AND TIME>'2019-01-11 00:00:00' AND TIME<'2019-01-11 00:10:00'

http://127.0.0.1:8086/query?chunked=true&db=yunhedb&epoch=ns&q=select+%2A+from+TAGDATA+where+TAGCODE%3D%27MZY_KF1%3A12LI-111004L01C%27+AND+TIME%3E%272019-01-11+00%3A00%3A00%27+AND+TIME%3C%272019-01-11+00%3A10%3A00%27

删除表:

drop measurement mydb

1、显示所有数据库:

show databases

2、创建数据库:

 create database test

3、使用某个数据库:

use test

4、显示所有表

show measurements

5、新建表和插入数据

新建表没有具体的语法,只是增加第一条数据时,会自动建立表

insert results,hostname=index1 value=1

用户验证:

auth

显示为常规日期格式:

precision rfc3339

-------------------------------

用户管理

a.显示所有用户:

 show users

b.新增用户:

    --管理员用户
  4.  
    create user "admin" with password 'admin' with all privileges

c.删除用户

drop user "user"

 -------------------------------

--查询保存策略
show retention policies on yunhedb

--修改保存策略(2年)
alter retention policy "autogen" on "yunhedb" duration 730d replication 1 default
