<ask> how to get any value from graph using API ?

[anwar]

Hi All,

I just try to using zabbix API. I following step by step from https://www.zabbix.com/documentation/2.2/manual/apihttps://www.zabbix.com/documentation/2.2/manual/api

i trying to using get method to get value from graph like bellow :

{
    "jsonrpc": "2.0",
    "method": "graph.get",
    "params": {
        "output": "extend",
        "sortfield": "name",
         "hostid": "10084"
    },
    "auth": "50ba559f6d083aa6454b8b3c4c203baa",
    "id": 1
}

Then i get value like bellow :

{
    "jsonrpc": "2.0",
    "result": [
        ...

        }
     
       ...

    ],
    "id": 1
}

From that output i can't get any value which like on graph which show on Zabbix Dashboard Graph.i also don't get any value on any graph which show on json output.

How i can get value CPU Load like :

processor load (1 min average per core) [avg] last:0.23 min:0.02 avg:017 max:0.74

processor load (5 min average per core) [avg] last:0.17 min:0.02 avg:017 max:0.4

etc



Anyone could help me to solve this ?

It's happen on almost graps on zabbix graph.

I've client on windows as zabbix agent.Inside these client there is disk space usage graph which tell me that :

15.61 GB (color: green)
21.49 GB (color: red)

But on json graph method i just found :

 "hosts": [
                {
                    "hostid": "10085"
                }
            ],
            "graphid": "540",
            "name": "Disk space usage C:",
            "width": "600",
            "height": "340",
            "yaxismin": "0.0000",
            "yaxismax": "0.0000",
            "templateid": "0",
            "show_work_period": "0",
            "show_triggers": "0",
            "graphtype": "2",
            "show_legend": "1",
            "show_3d": "1",
            "percent_left": "0.0000",
            "percent_right": "0.0000",
            "ymin_type": "0",
            "ymax_type": "0",
            "ymin_itemid": "0",
            "ymax_itemid": "0",
            "flags": "4"
        }

There is no value which reprensented 15.61 GB or 21.49 GB.

Anyone could help me how i can get these value ?

Thanks

If you need a history value, use history.get method.

[Pavels]

Currently there is no way to retrieve the aggregated values displayed on a graph. But, like Heilig said, you can access "raw" history values via the history API.
