FROM ticket There is nothing Grafana can do if you specify a group by time manually.The dashboard I linked to has a template variable called summarize that is set to auto, but you can specify how many bars you want, so when you zoom out the same number of bars will be shown. So you will never overload Grafana with a million data points. evaluate some function. Could you please explain me this ? What happened: pq: SQLParseException: 'ap_mac_address' must appear in the GROUP BY clause or be used in an aggregation function. ) X on week(T.created_on)=X.Week SELECT #25498, @Totalus; Transformations: enable transformations reorder. But still with the "way too many data points"-protection of time($interval).Some logic to select the maximum between user specified group (if available) and time($interval).that is what the interval variable does :).The $interval isn't used in the example you provided. Set fielddata=true on [user_name] in order to load fielddata in memory by uninverting the inverted index. last 90 days). Anyways, I am trying to make som time graph where I show top interface (or whatever) over time. I think you are misunderstanding how this works, if you have ave last 90 days and group by 10m and a small graph influxdb will return more data points than needed, and InfluxDB is really slow for large time ranges, (if you dont have rollups). I am looking to have my graph grouped by week, useful information here helps me to accomplish what we have here. but you can control how many bars you want in the template variable options.But "$interval" and "$summarize" are never passed to influxdb, are they? Both should be capped by the graph resolution.Anyway, I hope I hav explained the issue clear enough for others to understand. Now at the time of the graph, I am looking to have the 2 values on the same group by WW, stacked.SELECT DISTINCT CONCAT(“WW”,week(T.created_on)) as metric,X.SLAEXP as value,Y.SLAMET as value1,Unix_timestamp(now()) as time_sec,__timeFilter(created_on) and status = 1 and datediff(updated_on, created_on) > 0 and projectId in(2) There doesn't seem to be any support for functions inside the group by field, e.g. GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.By clicking “Sign up for GitHub”, you agree to our.I've added my own templating variable with which I want to control the data point grouping resolution. Could be useful regardless of the issue being fixed or not.I think you are misunderstanding how this works, if you have ave last 90 days and group by 10m and a small graph influxdb will return more data points than needed, and InfluxDB is really slow for large time ranges, (if you dont have rollups). I am trying to create a query that groups the data by "Api" field and selects a value field by using prometheus and grafana. Same with the templating variables.So, rather than just substituting variables with their values Grafana could(?) Can you open chrome dev tools and inspect the raw request being sent to InfluxDB? Still you can see the issue I'm trying to point out if you zoom out to last 90 days and toggle between 10m and 30m resolution. It will also respect a min limit you can specify below your influxdb queries or in the data source options (like.You can also create a interval template variable that also has an auto option that works similar but you have some control over how many steps the auto option should aim for.Are there any use cases for queries that return substantially more data points than horizontal pixels? Otherwise one could argue that the group by time($interval) should always be in effect.I understand if there are no clean ways of adding this "feature". when I try to use Group by Terms field Grafana says Fielddata is disabled on text fields by default. I'll just need to avoid selecting stupid combinations of resolution and time span.group by time($interval) is the default . #26016, @nabokihms; heatmap: reduce the aggressiveness of hiding ticks/labels when panel is small. Both 10m and 30m result in sub-pixel resolution regardless of the series specific "group by" is set to "time(auto)" or "time($interval)".I would have liked to see the same performance and same graph for 10m and 30m if the "group by" was set to "time($interval)" when zoomed out far enough (e.g. On the right side of the query editor there is the option to switch to edit mode.This adds a 4day offset to the group by time.Do you know hw could I use this syntax as default ? but in some cases you want larger group by buckets (for bar charts for example).Ah yes, larger groups I understand. My problem is that when I … My (Grafana) graph should show a line based on each MAC's changing signal strength. For example the $interval is replaced by an actual time range that influxdb understands. Hello, I am looking to have my graph grouped by week, useful information here helps me to accomplish what we have here. group by max($myvar, time($interval)).you can't, you can either let Grafana control the interval, in this case it will try to set it so that InfluxDB returns at most the same number of data points as the graph has pixels. Or at least by the way of the inverval variable ?I indeed use a variable with custom values : 1d,2d,1w,2w,30d , and it would be great if I could replace my 1w by this updated value, but I can’t find how to do this.I use only days and weeks in my template, so it is not a problem for me to add this into variable queries (excepted I spent some time changing this in every query in my dashboard),Group by week, data displayed on thursday. count(id) as "SLAMET" That's what I want to accomplish; select-ably larger groups. Instead the user selectable $summarize is used in the graph-specific "group by" ("Group by time interval" below all the queries).Now, the example provided does not have that many data points, so performance is not that bad. Transformations: Group by and aggregate on multiple fields. GROUP by week(created_on) INNER JOIN ( This works as expected by adding $myvar to the "Group by time interval" field for my graphs.So, my question is how I could control the group by time interval through my templating variable, but still use time($interval) as a upper limit on the resolution. The time period I'd display is relatively short, therefore retention is also quite short. Now at the time of the graph, I am looking to have the 2 values on the same group by WW, stacked. I would like to have my datapoints on mondays instead of thursday, but I don’t understand logic behind the scene. #27197, @dprokop; grafana-cli: Add ability to read password from stdin to reset admin password. I can’t see field.keyword when I try to build Grafana chart with elasticsearch data source. I send to influx 1 data per day, and when I want to change time interval for using weeks, I have as wanted one datapoint every week, but this datapoint comes every thursdays. WHERE. There's a performance penalty for 10m. Their.I take it that Grafana does some pre-processing of the queries before passing them to influxdb. Since devices come and go I cannot formulate queries that group by MAC address beforehand. There is a syntax for getting what you want but i think you cant do it with the gui editor. There is nothing Grafana can do if you specify a group … week(created_on) as Week, I have selected a Time range for the dashboard [ Jan 2016 to Feb end 2017 ] and my data points are only in Feb 2017.Successfully merging a pull request may close this issue.You signed in with another tab or window.http://play.grafana.org/dashboard/db/influxdb-templated-queries,http://play.grafana.org/dashboard/db/interval-template-variable. Grafana/ClickHouse - GROUP BY with limit that summarizes “others ... Viewed 26 times 0. so, I am fairly new to Grafana and ClickHouse so please bear with me. #27016, @lrstanley So Grafana will issue a query to InfluxDB with a group by(1s) which should in your case (and in mine) return the raw data, which it does for me, but for you it looks strange. In my case I would like to return the largest time range out of two; $summarize and time($interval).yes Grafana interpolates them, you can set a lower limit for the $interval built in variable.I have a query on using Interval variable. I have a strange behavior on my grafana panel.I send to influx 1 data per day, and when I want to change time interval for using weeks, I have as wanted one datapoint every week, but this datapoint comes every thursdays.I would like to have my datapoints on mondays instead of thursday, but I don’t understand logic behind the scene.I guess you are using influxdb. Hi all, I have a strange behavior on my grafana panel. Note that this can however use significant memory.
