我有一个在 Ubuntu 20.04 上运行的虚拟机，我安装了 Telegraf、InfluxDB 和 Grafana。
除了我尝试让 telegraf 在后台工作时，一切都正常。
手动启动正在运行的 Telegraf 的命令：
telegraf --config http://XXX.XX.X.X:8086/api/v2/telegrafs/XXXXXXXXXXX
返回我：
2021-03-14T00:02:27Z I! Starting Telegraf 1.17.3
2021-03-14T00:02:27Z I! Loaded inputs: cpu disk diskio mem net processes swap system

2021-03-14T00:02:27Z I! [agent] Config: Interval:10s, Quiet:false, Hostname:"XXXXX", Flush Interval:10s
到目前为止一切都很好。
但无法运行此服务（/lib/systemd/system/telegraf.service）：
[Unit]
Description=The plugin-driven server agent for reporting metrics into InfluxDB
Documentation=https://github.com/influxdata/telegraf
After=network.target
[Service]
EnvironmentFile=-/etc/default/telegraf

ExecReload=/bin/kill -HUP $MAINPID
Restart=on-failure
RestartForceExitStatus=SIGPIPE
KillMode=control-group

一切启动顺利，但检查服务状态后我得到了：
14T00:10:46Z E! [agent] Error writing to outputs.influxdb: could not write any address
14T00:10:56Z W! [outputs.influxdb] Metric buffer overflow; 25 metrics have been dropped

14T00:11:16Z E! [agent] Error writing to outputs.influxdb: could not write any address
并且 InfluxDB 没有获取任何数据，Grafana 也是如此。
有人能帮我解决这个服务问题并让 Telegraf 在后台运行吗？

这些信息很难找到！我在这里找到了解决方案：
https://github.com/influxdata/telegraf/issues/8395。
所以你要做的就是将 INFLUX_TOKEN 变量添加到/etc/默认/telegraf例如：
INFLUX_TOKEN=mytoken
