使用 InfluxDBClient 批量插入数据的步骤如下:
1. 创建 InfluxDBClient 实例,并连接到 InfluxDB 服务器:
```
from influxdb import InfluxDBClient
client = InfluxDBClient(host='localhost', port=8086)
client.switch_database('mydb')
```
2. 构造数据点列表,每个数据点是一个字典对象,包含以下字段:
- measurement:数据点的度量名称。
- tags:一个字典对象,包含数据点的标签。
- time:数据点的时间戳。
- fields:一个字典对象,包含数据点的字段。
例如:
```
points = [
{
"measurement": "cpu",
"tags": {
"host": "server01",
"region": "us-west"
},
"time": "2021-06-01T00:00:00Z",
"fields": {
"usage": 0.5
}
},
{
"measurement": "cpu",
"tags": {
"host": "server02",
"region": "us-east"
},
"time": "2021-06-01T00:00:00Z",
"fields": {
"usage": 0.8
}
}
]
```
3. 调用 InfluxDBClient 的 write_points() 方法,将数据点列表写入 InfluxDB:
```
client.write_points(points)
```
完整代码如下:
```
from influxdb import InfluxDBClient
client = InfluxDBClient(host='localhost', port=8086)
client.switch_database('mydb')
points = [
{
"measurement": "cpu",
"tags": {
"host": "server01",
"region": "us-west"
},
"time": "2021-06-01T00:00:00Z",
"fields": {
"usage": 0.5
}
},
{
"measurement": "cpu",
"tags": {
"host": "server02",
"region": "us-east"
},
"time": "2021-06-01T00:00:00Z",
"fields": {
"usage": 0.8
}
}
]
client.write_points(points)
```
