{
  "RequestData":{
    "Groups":[
      {
        "GroupName":{
          "TextId":"Hardware"
        },

          {
            "Description":{
              "TextId":"ODU current measurement"
            },
            "Id":0
          }
        ]
      },
      {

        ]
      }

}

>Solution :

anything like this?

traffic_group = h[:RequestData][:Groups].find do |group| 
  group[:GroupName][:TextId] == 'Traffic'
end
if traffic_group 
  http_get_traffic = traffic_group[:Tests].find do |test| 
    test[:Description][:TextId] == 'HTTP get traffic' 
  end
  if http_get_traffic
    http_get_traffic_id = http_get_traffic[:Id]
    puts "HTTP get traffic id: #{http_get_traffic_id}"
  else
    puts 'no http get traffic node found'
  end
else
  puts 'no traffic group found'
end
