What Grafana version and what operating system are you using?
Grafana 7.5.15 on fedora 35
What are you trying to achieve?
Display average by hour.
How are you trying to achieve it?
SQL Query
SELECT
$__timeGroup(ts_mesure,1h) as time,
avg(masse) as value
FROM mesures
WHERE
$__timeFilter(ts_mesure) AND
proprietaire = $proprietaire AND
numero_ruche = $numero_ruche
GROUP BY 1
ORDER BY 1
What happened?
The time is UTC. When I use the series directly (without average and $__TimeGroup), display is right.
When I use the SQL Query above, data is displayed like UTC was localtime (-2h offset)
What did you expect to happen?
Have the display like raw series (without) offset.
Can you copy/paste the configuration(s) that you are having problems with?
See above query
Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
No
there are many threads on here about using those time macros with a SQL data source, and managin UTC issues. I highly recommend you search through the forum for similar topics
SELECT
ts_mesure AS “time”,
masse
FROM mesures
WHERE
$__timeFilter(ts_mesure) AND
numero_ruche = $numero_ruche AND
proprietaire = $proprietaire
ORDER BY ts_mesure
Down, to obtain an average per hour :
SELECT
$__timeGroupAlias(ts_mesure,1h,0),
avg(masse) as poids
FROM mesures
WHERE
$__timeFilter(ts_mesure) AND
proprietaire = $proprietaire AND
numero_ruche = $numero_ruche
GROUP BY 1
ORDER BY 1
The two panels use the same data, with time in UTC.
