Hello everyone,

I check a couple of post in the Zabbix Forum and others sites to find a solution to download a graph using a curl command.

curl -X GET -v -o chart.png --cookie 'zbx_sessionid=#{zablogin}' "[URL="http://10.100.5.46/zabbix/chart.php?from=now-1M&to=now&itemids=72351&profileIdx=web.item.graph.filter&width=1733"]http://192.168.0.10/zabbix/chart.php?from=now-1M&to=now&itemids=72351&profileIdx=web.item.graph.filter&width=1733[/URL]"

The function zablogin is

def zabpost(payload)
  req = Net::HTTP::Post.new("/zabbix/api_jsonrpc.php", initheader = {'Content-Type' =>'application/json'})
  req.basic_auth "script", "scr1pt"
  req.body = payload
  response = Net::HTTP.new("[URL="http://10.100.5.46/zabbix/chart.php?from=now-1M&to=now&itemids=72351&profileIdx=web.item.graph.filter&width=1733"]192.168.0.10[/URL]", "80").start {|http| http.request(req) }
  puts "Response #{response.code} #{response.message}: #{response.body}"
  return JSON.parse(response.body)
  #return JSON.parse(response.body, object_class: OpenStruct)
end

def zablogin
  payload = '
    {
      "jsonrpc":"2.0",
      "method": "user.login",
      "params": {
        "user": "script",
        "password":"scr1pt"
      },
      "id": 0
    }'
  temp = zabpost(payload)
  return temp["result"]
end

Unfortunately, when I run this, I get an empty graph :



Could you help me to find a solution ?

Thanks,
