Question

我正在尝试使用InfluxDB。我正在使用他们的文档中的修改示例来生成一些随机测试数据但是当我用节点运行时它会显示[错误：没有主机可用]。我尝试通过curl和web控制台连接到InfluxDB，它们都工作，所以我不确定它在哪里失败。

我刚刚安装了Influxdb和涌入npm所以有最新版本。

var influxdb = require('influx');
client = new influxdb.InfluxDB('localhost',8086, 'root', 'root', 'tempdb');

// start time of 24 hours ago
var backMilliseconds = 86000 * 1000;
var startTime = new Date() - backMilliseconds;
var timeInterval = 60 * 1000;
var eventTypes = ["click", "view", "post", "comment"];

var cpuSeries = {
  name:    "cpu_idle",
  columns: ["time", "value", "hostName"],
  points:  []
};

var eventSeries = {
  name:    "customer_events",
  columns: ["time", "customerId", "type"],
  points:  []
};

for (i = 0; i < backMilliseconds; i += timeInterval) {
  // generate fake cpu idle host values
  var hostName = "server" + Math.floor(Math.random() * 100);
  var value = Math.random() * 100;
  var pointValues = [startTime + i, value, hostName];
  cpuSeries.points.push(pointValues);

  // generate some fake customer events
  for (j = 0; j < Math.random() * 10; j += 1) {
    var customerId = Math.floor(Math.random() * 1000);
    var eventTypeIndex = Math.floor(Math.random() * 1000 % 4);
    var eventValues = [startTime + i, customerId, eventTypes[eventTypeIndex]];
    eventSeries.points.push(eventValues);
  }
}

client.writeSeries([cpuSeries, eventSeries],{},function(err){
    if(err) {
        console.log("Cannot write data",err);
    }
});

我认为构造函数已更改为使用选项图而不是使用位置参数。见this example on the github repo

InfluxDB [错误：无主机可用]
