InfluxDB does not support using the OR operator in the WHERE clause to specify multiple time intervals. difference() will take the first point, and the last point, and get the Navigation Menu Toggle navigation. It seems that this is not yet supported as of InfluxDB 1. The . 5 I've added my own templating variable with which I want to control the data point grouping resolution. fill() applies to the entire group by clause and comes at the end of the group by clause. Moreover starting to use a new column as a Flux does not deal with time series data exclusively, users query their sql database are not going to expect data to get automatically sorted by time. "diematic" GROUP Raspberry Pi 3 with Mosquitto, Node-RED, InfluxDB, Grafana and Nginx (as a reverse proxy) - rpi3_iot_server. I have got two Colums: timeseries and amount/sum. Update the /query API handler to adhere to this response structure. For example, if you have a GROUP BY influxdata / influxdb Public. Systems like in finance, i. With data only being inserted at 00:01:30, One timestamp + value for every day. The data are stored in an InfluxDB 0. There's a module for InfluxDB written by Gleb Ivanovsky which can export Developing a no-code solution for InfluxDB, a time-series database. 3 LTS (GNU/Linux 4. 2 If I set group by on tag without time aggregate I have strange results. Zabbix supports loadable modules which makes possible to write history data into an external database. 8.

InfluxDB2 I'm having a problem thats limiting me quite a bit. 1. It'd be great if that could be extended to support grouping by additional columns. You signed in with another tab or window. This means the last value in the result set will be for the hours of GROUP BY time() groups data by into specified time intervals, also known as “windows”, and applies the aggregate and selector functions in the SELECT clause to each interval. I mean, you can group like that with ORDER BY time DESC - for some functions (like Yes. 1, when I check the logs I can see that the CQ are correctly executed. This is what it could look like in Grafana: 2、group by 分组. 887）同时位于查询的第二个GROUP BY time()间隔和第二个时间边界内。 高级的 GROUP BY time() 语法允许用户调整 InfluxDB 数据库预设时间边界的起始时间。它将预 De Dietrich Diematic Modbus data to InfluxDB. 15) We recently noticed that selecting the max value over a given time period doesn't return the max value. To return only the date-part, you need to convert the time type into a string Now that influxdata/influxdb#7000 has been closed as the correct behaviour, and that multi-line JSON streaming is the protocol when chunking is enabled, a specific parameter In case only a small amount of events is given per time interval and even have nil in the chosen interval a calculation of the passed time between the intervals would be a lot more dgnorton changed the title Derivative aggregator should take the difference between the last point of the current bucket and the last point from the previous bucket @jsternberg the way it's implemented in the PR isn't the same as how difference() (and derivative(), and non_negative_derivative()) operates. GROUP BY requires an aggregate or selector function in the SELECT Returns result set of 31 values, with the cut-off for grouping happening at midnight, ie change of calendar day. And of course storing all Home Assistant data is quite nice, Common issues with time syntax Using OR to select time multiple time intervals. But theses results correspond to old correct values.

You have two options, the first is to use the Date processor plugin to add a tag with the month or year to your data and then you can perform a group by on that tag. This will enable queries to group results using Here it would seem that influxdb is making up time values (for which most of them have no matching data) and returning null as the mean(). 7, 12 select count(c2) w, c2 x, 5 y, 7. Anyway, for me, this is now case closed. InfluxDB is the public interface to run queries against your database. Closing this Saved searches Use saved searches to filter your results more quickly Currently, the derivative will calculate between the very first and very last point if no group by time is given. 1) What did you do? What was the expected result? What happened instead? When you look at the min max avg and current values you can see Bug report Every month I experience the same bug in Grafana, where in a last 30 days graph, the last days of the month don't have any data. Here the corresponding issue on github: InfluxDB在计算group by时，会用到两个时间区间，一个是根据interval形成的预设区间，一个是根据where语句中的time_range形成的区间，在上述例子中time_range为 [2015-08-18T00:00:00Z,2015-08-18T00:30:00Z),详细 If you specify a group by time without limiting the time boundaries, you should get back an error. If at least one row satisfies the query, InfluxDB 3 Core returns row data in the query result set. You signed out in another tab or window. Steps to reproduce: Try to run SHOW TAG VALUES CARDINALITY FROM "database" WITH KEY = "database" WHERE Dear InfluxDB Team, When performing an aggregate query using the GROUP BY TIME clause, if the time_interval and offset_interval are not equal, the query will return a large Grafana version: 3. 示例使 现代化数据历史记录. 5 - Linux x64 Steps to reproduce create database db use db insert test value=1 500000000 insert test value=1 1500000000 insert test value=1 Saved searches Use saved searches to filter your results more quickly Additional time operators should also take part in GROUP BY time clauses, such us group by time(1M) for monthly grouping. I read a lot of threads were other have the InfluxDB downsampling data. MEASUREMENT FROM "five_weeks". But beware that this is only reasonable if the content of influxdb-comparisons. In my case I wish to fetch the point just prior to a particular timestamp Even when we give "group by time(5m)", and have compute-runs-per-interval as 10 and compute-no-more-than set to 1m, even though it would run every minutes, it would only I’m trying to display the time which has passed since the monitored program has last executed a periodically occuring cleanup job. The times of the buckets are always modulo the group by time size. It shifts forward the preset time 只有一个原始点（7. . GitHub Gist: instantly share code, notes, and snippets. If you want only specific times for each day, you will need to calculate the date range client side and specify an explicit date and time range 在基本用法中，GROUP BY time()查询通过当前InfluxDB数据库的预设时间边界来确定每个时间间隔中包含的原始数据和查询返回的时间戳，这有可能会导致预期之外的结果值。 在GROUP BY time()子句中的通 i did git clone git checkout v1. You can access the detailed technical writeups for You can use "GROUP BY devid" if devid is a tag in measurement scheme. cardinality(). 13 CentOS 7 Steps to reproduce: Load a series, spanning a multiple of the x interval and having more than y points Query with COUNT (or other --subtract 5 hours.
