What are the different methods to write data to InfluxDB?

Methods:

1. HTTP API: Direct HTTP POST requests with Line Protocol
2. Client libraries: Official libraries for various languages
3. CLI: Using influx write command
4. Telegraf: Data collection agent
5. Third-party tools: Grafana, custom applications

HTTP API example:

curl -XPOST 'http://localhost:8086/write?db=mydb' \
  --data-binary 'measurement,tag1=value1 field1=123.4'

Client library example (Python):

from influxdb import InfluxDBClient

client = InfluxDBClient('localhost', 8086, 'user', 'password', 'mydb')
data = [
    {
        "measurement": "temperature",
        "tags": {"location": "office"},
        "fields": {"value": 23.5}
    }
]
client.write_points(data)
