我有一个名为reading
的度量,其中所有行的格式为:
time channel host value
2018-03-05T05:38:41.952057914Z "1" "4176433" 3.46
2018-03-05T05:39:26.113880408Z "0" "5222355" 120.23
2018-03-05T05:39:30.013558256Z "1" "5222355" 5.66
2018-03-05T05:40:13.827140492Z "0" "4176433" 3.45
2018-03-05T05:40:17.868363704Z "1" "4176433" 3.42
其中channel
和host
是标记。
有没有办法可以自动生成连续查询,以便:
host_channel
到目前为止,我一直在逐一进行,例如
CREATE CONTINUOUS QUERY 4176433_1 ON database_name
BEGIN
SELECT mean(value) INTO 4176433_1
FROM reading
WHERE host = '4176433' AND channel = '1'
GROUP BY time(1m)
END
但有一种方法可以自动获得每个主机1m的采样时间。任何时候将新主机添加到数据库?谢谢!

由于原因,无法在InfluxDB中执行此操作。在测量名称中编码标记值与InfluxDB官方最佳实践和being discouraged相矛盾。
我建议你一起去:
CREATE CONTINUOUS QUERY reading_aggregator ON database_name
BEGIN
SELECT mean(value), host + '_' + channel AS host_channel
INTO mean_reading
FROM reading
GROUP BY time(1m), host, channel
END
