I want to remove time range selector from grafana dashboard to not query for specific selected time range. I am using influxdb and I want to load all data without selecting specific time range and query with some where clausess. Is it possible?
In the dahboard setting enable Hide time picker and all InfluxDB queries write in the raw mode without time conditon ($timeFilter macro).

For my Grafana panel i would like to extract and display the hours of a date from a given timestamp series
For example the timestamp 1628274040 which is 2021-08-06 18:20:40 (CET) i would like to only have "18:20:40" and display this comparable in my panel (display as graph).
How to do that? The underlying data is influxDB and the query is influxQL. I searched the grafana dashboard for converting function but dont find any.
I do not understand how you imagine to present this data in Grafan graph panel.
But I know that there is possibility to make it as a table with Datatable Panel Plugin by setting "Column Style" of "Time" as "HH:mm:ss".
It will allow you to present your data as a table with format exactly as you described.
Realisation example - image
This will return current date, like "24/05/22":
${__to:date:DD/MM/WW}
This will return Timestamp from today date, like "1653447599999":
${__to}
I am trying to get data of "last 5 minutes" which is an option in the above top-down menu in grafana. I have used the $timeFilter variable but when selecting the last 5 minutes, it is returning data of more than 5 minutes and the query being created is timestamp>=(unix time), whereas I want the query to be "between start time and end time".
How do I achieve this in Grafana?
did you try to turn off the "extrapolate" checkbox inside Query Editor?
which clickhouse-grafana plugin version do you use?
when you use "last 5 min" query
what is your browser time zone UTC?
or you just change UTC only in "date-range" picker on top-right corner?
if yes, try to return date time range picker timezone to your timezone and try again
I am having troubles understanding how the following works
from=now-1h&to=1568789063000
but when I do
from=1568789063000-1h&to=1568789063000 it doesn't work.
I have tried doing it directly in the URL, doesn't work.
from=1568789063000-1h&to=1568789063000 and from=1568789063000-2h&to=1568789063000 shows me the same time range on the graph whereas
from=now-1h&to=1568789063000 and from=now-2h&to=1568789063000 shows me different time range in the graph.
Additionally, I also tried manipulating this by using the option Data link in the visualization where I tried using
from=${__value_time}-1h&to=${__value_time} and I don't plan to use __url_time_range becasue I want custom time range around one point.
Can please anyone explain what I am doing wrong or what am I missing?
The Unix timestamps you're using (1568789063000) all translate to the same time. So doing from=1568789063000&to=1568789063000 doesn't return a valid period of time as
1568789063000 - 1568789063000 = 0
now-1h and now-2h will show different time ranges because you're telling Grafana to start the graph either at one or two hours before the time that you're making the render request, even if the to time is always the same
As for the issue using the absolute timestamp with a relative "offset" (1568789063000-1h), this isn't allowed. Instead you should subtract 3600000 from the starting (from) timestamp which equals 1568785463000. So, if you do from=1568785463000&to=1568789063000, it should work instead of from=1568789063000-1h&to=1568789063000.
Similarly for -2h, you should subtract 7200000: from=1568781863000&to=1568789063000.
Is it a requirement that you must use a time or datetime column in postgres to pull metric's on a Grafana dashboard?
I ask because I have a column just with a date only and I'm unable to show metrics base on dates only. Unless I am missing something in the documentation. Postgres in Grafana
If anyone has any helpful information, it would be greatly appreciated.
All I need is just a starting point.
I am a new user to Grafana and I'm trying to figure this out.
According to documentation:
If you set Format as to Time series, for use in Graph panel for example, then the query must return a column named time that returns either a sql datetime or any numeric datatype representing unix epoch in seconds.
So, all you need is to convert your column with date to unix epoch and name it as time. You can do it yourself or use macros provided by grafana (see docs) for convertion which are expanded into native postgres expressions. It is also helpful to look at 'Generated SQL' to see the actual query sent to database.
We are moving BackEnd tables from a large MS Access application to postgresql.
In one table we have a field ErZei defined in postgres as
time(0) without time zone DEFAULT ('now'::text)::time(0) without time zone
Inside this field only the time value is stored, the day value has his own field.
The linked table inside Access shows the current day in front of the time value. Using the 24-hour format for displaying time values in Access looks fine. But by entering the field, the current day appears automatically.
If I call the time field by SQL-Query SELECT * from ..., I get the same result: everytime the current day value in front of the time value.
Inside postgres everything works fine.
Also a test with a ODBC query tool shows only the time.
How could I configure MS Access to show only the time value without the day in case of postgres time columns?
I can't find an option in the Access globals.
We use
MS Access 2016
ODBC: PostgreSQL Unicode 10.00.00 PSQLODBC35W.DLL
13.10.2017
PostgreSQL 10.1 as backend on ubuntu
