flux support

[mroe1234]

Using world map-panel .3.2 and Grafana 6.7.4
my flux query:

from(bucket: "ntopng/autogen") 
  |> range(start: -2h) 
  |> filter(fn: (r) => r._measurement == "country:traffic" and (r.ifid == "5") and (r._field == "bytes_ingress")) 
  |> sum()
  |> drop(columns: ["_measurement","ifid"]) 
  |> group(columns: ["country"])

I have also tried:
|> duplicate(column: "country", as: "_field")

The output data via the influx cli looks like:

Table: keys: [country]
    country:string                     _start:time                      _stop:time           _field:string                  _value:float

Table: keys: [country]
    country:string                     _start:time                      _stop:time           _field:string                  _value:float

Table: keys: [country]
    country:string                     _start:time                      _stop:time           _field:string                  _value:float  
   UZ  2020-07-06T14:13:30.643974014Z  2020-07-06T16:13:30.643974014Z                      UZ                      10035102  

However the map remains empty.

Got it to work using this.

from(bucket: "my bucket")
    |> range(start: v.timeRangeStart, stop: v.timeRangeStop) 
    |> filter(fn: (r) => 
    r._measurement == "something" and 
    r._field == "Lat" or
    r._field == "Lon" or
    r._field == "MCUTemp"
  )
  |> pivot(rowKey:["_time"], columnKey: ["_field"], valueColumn: "_value")

The above flux works for long/lat, but not if you want to use US,GB,RU 2 letter country codes.

Location Data: countries

This is my solution:

from(bucket: "pfsense")
 |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
 |> filter(fn: (r) => r["_measurement"] == "tail_ip_block_log")
 |> filter(fn: (r) => r["_field"] == "action" or r["_field"] == "direction" or r["_field"] == "host")
 |> pivot(rowKey:["_time"], columnKey: ["_field"], valueColumn: "_value")
 |> filter(fn: (r) => r.host =~ /^.*$/ and r.action == "block" and r.direction == "in")
 |> group(columns: ["geoip_code"]) 
 |> keep(columns: ["_time","geoip_code","action"])
 |> count(column:"action")
 |> map(fn: (r) => ({ r with _time: now() }))

credit to Grafana Issue #30290 for the last line:

|> map(fn: (r) => ({ r with _time: now() }))
This is the key to the problem of the error message: "TypeError: Cannot read property 'length' of undefined"

A transform "rename by regex" is also required:
Match: action\s(.*)
Replace $1

For reference this is my original fluxql query:

SELECT count("action") FROM "tail_ip_block_log" WHERE ("host" =~ /^$Host$/ AND "action" = 'block' AND "direction" = 'in') AND $timeFilter GROUP BY time(10m), "geoip_code"
