InfluxDB¶

InfluxDB 仅支持写入 Metric 种类的数据。

第一步: 搭建后端存储¶

自己搭建一个 InfluxDB 的 server 环境。

第二步: 增加配置¶

在 datakit.conf 中增加以下片段:

...
[sinks]
  [[sinks.sink]]
    categories = ["M"]
    target = "influxdb"
    host = "localhost:8087"
    protocol = "http"
    database = "db1"
    precision = "ns"
    timeout = "15s"
...

除了 Sink 必须配置通用参数外, InfluxDB 的 Sink 实例目前支持以下参数:

host(必须): HTTP/UDP host should be of the form host:port or [ipv6-host%zone]:port.
protocol(必须): http or udp.
database(必须): Database is the database to write points to.
precision: Precision is the write precision of the points, defaults to "ns".
username: Username is the influxdb username, optional.
password: Password is the influxdb password, optional.
timeout: Timeout for influxdb writes, defaults to 10 seconds.
user_agent: UserAgent is the http User Agent, defaults to "InfluxDBClient".
retention_policy: RetentionPolicy is the retention policy of the points.
write_consistency: Write consistency is the number of servers required to confirm write.
write_encoding: WriteEncoding specifies the encoding of write request
payload_size(UDP 协议专用): PayloadSize is the maximum size of a UDP client message, optional. Tune this based on your network. Defaults to 512.

第三步: 重启 DataKit¶

$ sudo datakit --restart

安装阶段指定 InfluxDB Sink 设置¶

InfluxDB 支持安装时环境变量开启的方式。

DK_SINK_M="influxdb://localhost:8087?protocol=http&database=db1&precision=ns&timeout=15s" \
DK_DATAWAY="https://openway.guance.com?token=<YOUR-TOKEN>" \
bash -c "$(curl -L https://static.guance.com/datakit/install.sh)"
