Hello @Anaisdg - let me clarify - yes, it would be ideal for Grafana to be able to accomplish such, but it is not possible, because Grafana can only work with what it is given, and the way that the UI structures things when it outputs them, it makes it impossible to accomplish the apparently simple requirement that I have in mind.
Consider I have a measurement with 3 tags: name, description, alias - when it comes to grafana charting, the title can only assigned the variable that it is associated with the repeat charts… hence my repeat chart titles would only be able to do: either name, alias, or description - the issue with my data is that sometimes there are descriptions and sometimes there aren’t, and sometimes they are the same for different entries - here is an example:
name description alias
eth0 Internet connection Eth.0
eth4 Tunnel to NY Eth.4
po1 Internet connection Po.1
When I make Grafana charts using the repeat function, I have to make them by alias (or name), but obviously I want my chart to display a title other than eth1 or Eth.1. As you can see not every interface will come with descriptions and not all descriptions are unique (Before anyone says: update the descriptions, there are 10s of thousands of interfaces - managed by different companies, so I can’t tell people how to run things… they don’t get paid by me). As you can see - I can not choose only description either, since some charts have common descriptions: empty or same value.
So the ideal scenario is to be able to concatenate tags same as in SQL I can concatenate fields (column values) - Yeah, I know, I know, this is not darn SQL - it just looks like it… (Hence Flux is a totally different syntax approach)
SELECT name+description, sum(IfHCInOctets) from bandwidth GROUP by name+description+sum
So now, any ideas how to go about it?
