Template variables per row

[MatMeredith]

I have the following use case.

• I have a set of nodes that I am monitoring
• Each nodes is one of a set of node types.

I can create template variables: node_types (containing the different node types) and nodes (containing all nodes of all types).

I want to show a graph for each node, but I want to group them by node type. Ideally, I would have a row repeat that repeats over each node type, and then have a panel repeat within the row that repeats over nodes of that type. But I don't think I can do this at the moment?

I have a similar need where I would love to be able to do something like iterating and array of dictionaries. Consider the following data

[
  {"var1":1,"var2":2,"var3":3},
  {"var1":2,"var2":3,"var3":5}
]

It would be great to be able to repeat both rows and panels to be instantiated for each member of the array with variables for each key.

It would also be great if this JSON could be entered manually or loaded from a URL directly potentially including other variables along the way. ie, if I were to define a global variable $host that resolves from a graphite query, I would love to be able to load JSON from a url https://example.com/give/me/some.json?host=$host

+1 I'm really missing this feature of template variables per-row. Instead, have to create separate dashboards. Actually, even per-graph template variables would be useful.

Another application:

• On row per $host
• One panel per $second_variable (mount point, network interface, docker instance,...)

The $second_variable needs to be evaluated once per $host. The current version (4.4.1) performs the evaluation just once and then returns the full outer join of $host and $second_variable. As hosts typically have different $mount_points/... this results in lots of empty (N/A) results.

• Semi-Workaround: Use table panel and colums per $second_variable. Downsides: Drill-Down doesn't work, Column overflow bug not yet fixed (i.e. all cells on a single row)

+1 I desperately need this feature to work. I am trying to use Prometheus snmp_exporter to gather metrics for Cisco switches and use Grafana repeated panels for displaying. the Grafana works magically well. However, I have difficulity to assign the title automatically on each panel based on the interface.

These are the sample of Prometheus data:

ifDescr{ifDescr="GigabitEthernet1/0/12",ifIndex="10112"} 1
ifDescr{ifDescr="GigabitEthernet1/0/13",ifIndex="10113"} 1
...
ifHCInOctets{ifIndex="10112"} 1.03615731929e+11
ifHCInOctets{ifIndex="10113"} 2.644180651e+09

Since all metrics are referenced with ifIndex, I managed to irate the rows by ifIndex. However, the title doesn't change along with the ifIndex:

I guess the only way to work is to have variable per row or panel. Please do let me know if there is any other way to achieve this. Thanks and regards, Roger

+1 I have encountered this issue in the following scenario:

1. The first template variable is a collection of hostnames (Multi-Value selection is enabled).
2. The second template variable Query whose value is a collection of full URLs of the selected hostname.

In order to repeat the entire valid permutations ie the Inner Join of both collections, I want to:

1. Repeat row on hostname values.
   2. Repeat panels within each row for the query result for the matching hostname.

Currently the panel is repeated on the value of the template variable in the dashboard context.

I would give this issue a shot and attempt to fix it and PR.

+1 I Have a similar issue Two template variables: "hosts" = {h1, h2} "metrics" = {m1, m2, m3} Row is templated for "hosts", so there are two rows "h1" and "h2". Each row should contain a graph for all metrics (for the host declared in a row) and singlestats with metric values templated for "metrics" (3 singlestats in each row). So, in fact after second row wrapping and unwrapping the graph is missing, there are only singlestats. The same behavior is noticed if there are more than two hosts (only first row has the graph, on the other it is missing) and if only some of the hosts (not "All") are ticked. Also behavior is the same if graphs are static (i.e. do not contain any template variables).

Just to add my 2cts here, sorry for notification everyone:

my use case is that i have a dashboard with say 15 panels, but only one of them is using the template. And it make quite hard to understand the relation between the two and why the other are not changing, ... so yeah if i could at least put them both in a single row, it would be helpful

[MartinRoenneburg]

+1 My use case: Prometheus / Grafana ... I use Grafana repeated rows to show details of a special controller (snmp data). This works fine. Problem: I repeat rows by a special index. Depending on that index i need to query/define variables (in my case the room and the rack) to query other significant values from a different database (the rack temperature) in the same row.

I have temperature measurements from different nodes (variable1) in different locations / rooms (variable2). I'd like to have a row per node (already possible) and then show the available measurement of the different rooms with a repeating panel. For that I would have to forward the selected variable of the row to the panel.

Having "On row iteration" and "On panel iteration" for refreshing variables would be very useful in many cases! Please, consider to implement it.

This would be the single most killer feature for us right now. We have a lot of use cases like what has been described above. There are various workarounds but they are usually more labor intensive and/or provide a lower quality UX such as unnecessary blank graphs for combinations with no results.
