Question: Help setting up Value groups/tags

[rdzimmer-zz]

I am new to Grafana but really like what I see so far. I am using Grafana 2.6.0 with InfluxDB 0.9.3 to monitor my Kubernetes environment.
I have setup some templates and graphs, but I'm having trouble with the 'Value groups/tags', specifically the 'Tag values query'. All of the online references I see online have a slightly different UI format when building templates, for example http://docs.grafana.org/reference/templating/. I've pasted a screenshot of what I'm trying below.
I'm currently trying to get any group/tag combination to work, so I've simplified my queries to try to get any group tags to work. I can see all of my pods in the group tags when I use the 'Tags query' 'SHOW TAG VALUES FROM "uptime" WITH KEY = "pod_name"'. However, when I select the tags it does not show anything. I am trying a 'Tag values query' of 'SHOW TAG VALUES FROM "uptime" WITH KEY = "pod_name" WHERE "pod_name" = $tag'. I've also tried just '$tag' or hard coding in a pod name.
Any suggestions would be greatly appreciated, thanks!

Tags query should be SHOW TAGS

[AlexMaksimkin]

Also have a problem with this two queries. My tags/tag_values queries are same as on picture above. Setup with InfluxDB v0.10, Grafana v2.6.0.

Both queries worked in InfluxDB and returned expected results (first - list of tags, second - list of hosts for specific tag), but in Grafana reaction on checkbox/clicking on tag is silence.

Also I see in browser debugger that Grafana do query when I click on tags and receive valid response:

Regarding @torkelo recommendation I tried to change "Tags query" to "SHOW TAGS", but then I see an error:

"Template variables could not be initialized: error parsing query: found TAGS, expected CONTINUOUS, DATABASES, DIAGNOSTICS, FIELD, GRANTS, MEASUREMENTS, RETENTION, SERIES, SERVERS, SHARD, SHARDS, STATS, SUBSCRIPTIONS, TAG, USERS at line 1, char 6"

What I do wrong? :)
Thanks!

the tag values query should return values that are a subset of the main values query? Are they?

I mean if you have a main query like:
show tag values with key = hostname

tag query:
show tag values with key = datacenter

tag values query:
show tag values with key = hostname WHERE datacenter=$tag

something like the above meaning the tag values query should return a subset of the main query

[AlexMaksimkin]

Yep, sure:
Main query: SHOW TAG VALUES FROM redis WITH KEY = "host"
Tags query: SHOW TAG VALUES FROM redis WITH KEY = "services"
Tag values query: SHOW TAG VALUES FROM redis WITH KEY = "host" WHERE services = '$tag'

All queries are checked in influxDB and returned expected results:
first query - all hostnames
second - all services
third - subset of hostnames with specified service
Then I click in tag in Grafana - I see in debugger that query for tag values also returns valid subset of hostnames, but selection in "hosts" checkboxes don't changed.

@AlexMaksimkin this strange, just tested this and it worked fine.

I have same issue when use grafana 4.0 and influxdb v0.13.0. and I saw it did not worked in http://play.grafana.org/dashboard/db/templating-value-groups
Could you please help us to review this issue?
Thanks!

I'm also using grafana 4. Having issues. I also see your link:
http://play.grafana.org/dashboard/db/templating-value-groups
Doesn't seem to have grouping tags working as expected.

@torkelo I believe @hoalequang is correct. This feature seems to have regressed. If I go to the templating-value-groups test dashboard, I see two tags available "America" and "Europe". Each tag has a tooltip that indicates which hosts belong to the region, but if I click one of the tags, I simply get a popup menu for selecting individual hostnames / IPs. The tags then disappear, never to return.

[Bklyn]

This seems to be a case of #6752

[tlintz]

The case/example above only worked for me after I used regex.
e.g: SHOW TAG VALUES FROM redis WITH KEY = "host" WHERE services =~ /.$tag./

Hi guys, i have a similar problem that I need help in, if anyone could help me on https://community.grafana.com/t/how-to-set-up-the-custom-tags-for-multi-value-in-grafana/15495 or
influxdata/influxdb#12809, it would be much appreciated
