C# 使用Zabbix API 获取监控设备CPU、内存、硬盘、网络数据
1.在 home控制器中添加 GetToken 方法，获取登录令牌。
public JsonResult GetToken()
{
string url = "http://1.1.1.1:8086/zabbix/api_jsonrpc.php";
Params @params = new Params() { user = "用户名", password = "密码" };
GetToken getToken = new GetToken()
{
jsonrpc = "2.0",
method = "user.login",
@params = @params,
id = 0,
auth = null
};
var data = Newtonsoft.Json.JsonConvert.SerializeObject(getToken);
Encoding encoding = Encoding.UTF8;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.Accept = "text/html, application/xhtml+xml, */*";
request.ContentType = "application/json-rpc";
request.ProtocolVersion = new Version(1, 0); //Http/1.0版本
byte[] buffer = encoding.GetBytes(data);
request.ContentLength = buffer.Length;
request.GetRequestStream().Write(buffer, 0, buffer.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
var result = reader.ReadToEnd();
return Json(result);
}
}GetToken实体类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace ZabbixTest.Models
{
public class GetToken
{
public string jsonrpc { get; set; }
public string method { get; set; }
public Params @params { get; set; }
public int id { get; set; }
public string auth { get; set; }
}
public class Params
{
public string user { get; set; }
public string password { get; set; }
}
}2.在home控制器中创建 GetData（）方法，用来获取各种数据。
public JsonResult GetData(string json)
{
string url = "http://1.1.1.1:8086/zabbix/api_jsonrpc.php";
Encoding encoding = Encoding.UTF8;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.Accept = "text/html, application/xhtml+xml, */*";
request.ContentType = "application/json-rpc";
request.ProtocolVersion = new Version(1, 0); //Http/1.0版本
byte[] buffer = encoding.GetBytes(json);
request.ContentLength = buffer.Length;
request.GetRequestStream().Write(buffer, 0, buffer.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
var result = reader.ReadToEnd();
return Json(result);
}
}3.修改index.cshtml，用于显示相关数据（没有则创建）。
@{
ViewBag.Title = "Home Page";
Layout = null;
}
4.创建 index.js 获取相关数据。
var token = "";
//获取登录信息
function GetToken() {
var data = {
};
$.ajax({
type: "POST",
url: "/Home/GetToken",
data: data,
dataType: "json",
success: function (re) {
var data = JSON.parse(re);
console.log(data);
token = data.result;
$("#token").val(data.result);
$("#dataTile").text(data.result);
}
});
}
//获取监控设备列表
function GetDevice() {
var json = {
"jsonrpc": "2.0",
"method": "host.get",
"params": {
"output": "extend",
},
"id": 1,
"auth": $("#token").val()
};
$.ajax({
type: "POST",
url: "/Home/GetData",
data: { "json": JSON.stringify(json) },
dataType: "json",
async: false,
success: function (re) {
var data = $.parseJSON(re);
console.log(data);
if (data.result.length > 0) {
var htmlstr = '';
console.log(data.result);
$.each(data.result, function (index, e) {
htmlstr += ' ';
});
$("#service").html(htmlstr);
}
}
});
//$("#showdata").text(JSON.parse(data).result);
}
//获取警报
function GetDeviceAlert() {
var json = {
"jsonrpc": "2.0",
"method": "alert.get",
"params": {
"output": "extend",
"actionids": 0
},
"id": 1,

async: false,
success: function (re) {
var data = $.parseJSON(re);
console.log(data);
}
});
}
//获取监控项
function GetDeviceTemplateid() {
var hostid = $("#service").val();
//监控项的key 是 zabbix 中配置的 具体见下图
//system.cpu.util[,user] 每分钟CPU使用率
//vm.memory.size[pused] 内存
//vfs.fs.size[/,pused] 硬盘

var jsoncpu = {
"jsonrpc": "2.0",

$.each(data.result, function (i, e) {

});
}
});
//内存使用率
var jsonmemory = {

// 根据 监控项ID 获取监控数据

function timestampToTime(timestamp) {

return Y + M + D + h + m + s;
}
//获取网路数据

}注意：
1. 监控数据必须在zabbix 中创建相关监控项才可以获取到数据。
2.网络数据是流量和，并不是此时刻的流量数。
