This guide walks through ## Examples of InfluxDB data grouping and aggregation operations In InfluxDB, you can use the GROUP BY clause to group data, and use aggregate functions to aggregate the grouped data. I’ve set up nine queries - one for each host GROUP BY is an optional clause used to group rows that have the same values for all columns and expressions in the list. influxdata. This guide walks through Learn how to apply aggregate operations to your queried data: Both aggregate and selector functions return a single row from each SQL group. “Grouping” partitions data into tables in which each row shares a common value for specified columns. So the measurement is connection_events with tags being: mac_address of connecting system, and some other metadata I have time data in InfluxDB with pairs of hostnames (field “host”) and CPU temperatures (field “temp”). Use the GROUP BY clause to group data by values. The data is gathered via an API call using infinity. To output an aggregation for each group, include an aggregate or selector 本文翻译自官网，官网地址： (https://docs. g. GROUP BY is an optional clause used to group rows that have the same values for all columns and expressions in the list. I am very new to Influx DB and curious, how does Group By Works. In that case when my first data entry was made on a Sunday, I don’t get any results until the next 7 days GROUP BY time() 间隔使用预设的以整数倍时间边界，独立于 WHERE 子句中的时间条件。输出数据使用窗口开始边界作为聚合的时间戳。使用 time() 函数的 offset 参数将时间边界向前或向后移动。 Hi all, I am using Influx 1. With Flux, you can group data by any column in your queried data set. Below you can see in the top row of the gauges the result of the query ‘loadpoints’ This query is an I am trying to aggregate and group data by column but I am not sure how to do that correctly because if I group by value all the columns get Use the GROUP BY clause to group data by one or more specified tags or into specified time intervals. This could be inferred from the syntax of group by Im trying to group by and count items on a table (to be displayed on a pie chart). how can I execute following MySql Query in InfluxDb: select mean (cputime), vm from CPU group by vm; GROUP BY time() 将数据分组到指定的间隔（窗口）中，也称为“窗口”，并在 SELECT 子句中对每个间隔应用聚合和选择函数。语法如下：在GROUP BY time()高级语法中，需要在SELECT子句中调用InfluxDB的函数，并在WHERE子句中指定时间区间。并且需要注意到的是，GROUP BY子句必须在WHERE子句之后！ 1. 7/query_language/data_exploration/) 本文介绍InfluxDB的GROUP BY子句的用法。 I search a way to group by substring/regex of a column: I search in the documentation https://docs. To output an aggregation With Flux, you can group data by any column in your queried data set. I have been InfluxDB select top n results from a group by tag Asked 9 years ago Modified 5 years, 8 months ago Viewed 41k times This InfluxDB Tech Tips post provides valuable tips on using a sample dataset to explore Flux and also explains the group key. For example, if you GROUP BY room and perform an I have some data in InfluxDB that is connected events for certain TCP connections. com/ without success. InfluxDB 的 GROUP BY time 子句可按时间分组聚合数据，支持设置时间间隔和偏移量。通过实例讲解如何用偏移量解决数据分组时间显示错误问题，并提供三种动态计算偏移量的方法，包 Use the GROUP BY clause to group data by one or more specified tags or into specified time intervals. The column "proc" is Is it something if, 1-> I have to do group by time (31d),month, year will work (does 30d takes from beginning of month)? 2-> shall i do group by InfluxDB using timestamp 0 (1970-01-01T00:00:00Z) as start time, and for each timestamp that is dividable by the group by interval, it create a boundary. I have a question about querying data when using group by time(7d) for example. time(time_interval,offset_interval) 在GROUP BY time()子句中的通过time_interval和offset_interval来表示一个连续的时间区间，该时间区间决定了InfluxDB如何通过时间来对查询结果进行分组。比如，如果 Use the GROUP BY clause to group data by one or more specified tags or into specified time intervals. For e. I'm afraid that the InfluxQL above won't work as currently InfluxDB only supports tags and time interval in GROUP BY clause, not the fields. com/influxdb/v1. 8 with InfluxQL. . So in this sql, the boundary Use the GROUP BY clause to group data by one or more specified tags or into specified time intervals. Use the GROUP BY clause to group query results by one or more specified tags and/or a specified time interval.
