[Bug] Issue with detecting template variable dependency when query ends with variable

[cheribral]

I am using grafana version 4.1.1-1484211277 with influx on CentOS 7, and am having trouble with a nested template variable.

I have one variable called pgstat which is used in 4 other variable queries. When I change $pgstat, 3 variables update, but one refuses to do so. The 'stat' variable seen below will not update. You can see the 3 top requests are updating the other variables. The remaining two queries are for the actual graphs.

The only difference is that $stat is a query for field keys rather than tag values. I'm not sure how, but could this cause the problem?

Can't replicate with the exact same setup.

[torkelo]

can you show the options of the stat variable?

Sorry for the delay, I was away on holiday for a bit. The difference between your setup and mine is that the stat variable isn't "show tag values", it is "show field keys".

Here is a screenshot of the options:

that does not change anything :(

[cheribral]

Apparently it does though ;)

Using the latest version, if I create a brand new dashboard with only two variables:

$pgmetric  show measurements
$stat	   show field keys from $pgmetric

Nothing happens when I change pgmetric. There is no request to the server to update the second variable.

If I change the second variable to:
show tag values from $pgmetric with key=schema
It makes a request every time I select something new in the first drop down.

managed to replicate this issue, only occurs when the query ends with a variable. Fixed in master (and in soon to be released 4.2 beta)

cool, thanks torkelo
