Repeat panel not repeating

Grafana
1

Hello all

I am working on building a status dashboard for my network devices. I’m using Prometheus and blackbox_exporter as my db; that seems to be working OK. I have a variable set up (Instance) to pull out the IP addresses; that seems to be working too as I can see the addresses listed under ‘Preview of values’ in the variable edit screen. I also get a dropdown list of all my addresses in the main screen of my dashboard.

I have a singlestat panel configured that correctly displays the status of whichever address I pick from the dropdown. That works fine. The panel itself is configured to repeat (Repear: Instance Direction: Horizontal Max per Row: 4) but it is not repeating. All I get is a single panel that switches between addresses via the dropdown.

variable: Instance
query: query_result(sum by (instance)(probe_success{job=“blackbox_icmp”}))
regex: .instance="(.?)".*

panel config:
query: probe_success{group=“firewalls”,instance=’$Instance’,job=“blackbox_icmp”}
title: $Instance
Repeat: Instance (selected from dropdown)
Direction: Horizontal
Max per row: 4

Grafana v6.2.1 (9e40b07)

Any ideas?

thx

Try to enable Include All option for the variable and select All value in the variable select box - not just single value.

That cured the non-repeating problem but now my panels say “no value”. When I look at the panel’s query inspector, the last entry says “result:Array[0]”.

Edit:
I’ve looked at this more closely. The problem seems to lie in how the $Instance variable is being handled. If I hard-code the ip address into the query, it works:

query:

probe_success{group="firewalls",instance="172.217.164.196",job="blackbox_icmp"}

result:

{
  "xhrStatus": "complete",
  "request": {
    "method": "GET",
    "url": "api/datasources/proxy/1/api/v1/query?query=probe_success%7Bgroup%3D%22firewalls%22%2Cinstance%3D%22172.217.164.196%22%2Cjob%3D%22blackbox_icmp%22%7D&time=1559227010"
  },
  "response": {
    "status": "success",
    "data": {
      "resultType": "vector",
      "result": [
        {
          "metric": {
            "group": "firewalls",
            "instance": "172.217.164.196",
            "job": "blackbox_icmp"
          },
          "value": [
            1559227010,
            "1"
          ]
        }
      ]
    }
  }
}

It chokes when I put in the $Instance variable:

query:

probe_success{group=“firewalls”,instance=“$Instance”,job=“blackbox_icmp”}

result:

{
“xhrStatus”: “complete”,
“request”: {
“method”: “GET”,
“url”: “api/datasources/proxy/1/api/v1/query?query=probe_success%7Bgroup%3D%22firewalls%22%2Cinstance%3D%22172%5C%5C.217%5C%5C.164%5C%5C.196%22%2Cjob%3D%22blackbox_icmp%22%7D&time=1559227043”
},
“response”: {
“status”: “success”,
“data”: {
“resultType”: “vector”,
“result”:
}
}
}

OK, I have narrowed the issue down to a replicatable set of steps. I think this may be a UI issue.

    • In the dashboard settings (cog menu), in the variable settings, I turn on 'Include all option" for the $Instance variable
  2. Update variable, save the dashboard
  3. In my dashboard I have a dropdown box with an option for ‘all’. I select it and my panel repeats but they all display “no value”
  4. Back to the cog menu, turn off “include all option” for my $Instance variable
  5. Update & save
  6. This is the weird part - when I go back to my dashboard, the panel repeats and displays info correctly. My dropdown box displays ‘all’ but it does not list ‘all’ in the available options when I click on it. If I pick an option, I get a single panel but I cannot go back to ‘all’ because it does not show in the dropdown list.
  7. I can get the panels to repeat & work again by following the above steps - turn on Include All, pick all from the dropdown, then turn off Include all.

A bug perhaps?

Edit - I just discovered I can get all working panels back by typing in ‘All’ into the dropdown

So, its been 5 years, gosh, lucky that community is the <3 of Grafana, thanks for the support, very kind of you…
But the thing is; as per documentation it should be a multi value, so check that option, the ‘all’ is not the one. The other thing; when it is multi value it is handled as String, you know, there are quotation marks. When not, then not. So thats why the query fails after changing the type of the variable.
I just run into the same thing, hope it helps to somebody.
Have fun.
Personally dont like Grafana, but the company had chosen this so…
