Telegraf是手动工作的，而不是后台的服务运行Telegraf。

Question

我有一个虚拟机运行在Ubuntu20.04上，我安装了Telegraf、InfluxDB和Grafana来监视VM和集群的节点。

除了我试着让telegraf在后台工作外，一切都很有效。

手动启动Telegraf的命令，该命令正在工作：

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! Loaded aggregators:
2021-03-14T00:02:27Z I! Loaded processors:
2021-03-14T00:02:27Z I! Loaded outputs: influxdb_v2
2021-03-14T00:02:27Z I! Tags enabled: host=XXXXX
2021-03-14T00:02:27Z I! [agent] Config: Interval:10s, Quiet:false, Hostname:"XXXXX", Flush Interval:10s

所以到目前为止一切都很好。

但是不可能运行此服务(/lib/systemd/system/telgraf.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
User=telegraf
ExecStart=/usr/bin/telegraf -config /etc/telegraf/telegraf.conf -config-directory /etc/telegraf/telegraf.d $TELEGRAF_OP>
ExecReload=/bin/kill -HUP $MAINPID
Restart=on-failure
RestartForceExitStatus=SIGPIPE
KillMode=control-group

[Install]
WantedBy=multi-user.target

这是一个很好的开始，但是在检查了我得到的服务状态之后：

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

而InfluxDB没有任何数据，所以Grafana。

有人能帮我解决这个服务问题，让Telegraf在后台工作吗？

这个信息很难找到！我也遇到了同样的问题，我在这里找到了解决方案：https://github.com/influxdata/telegraf/issues/8395。

因此，您所要做的就是将INFLUX_TOKEN变量添加到/etc/default/telegraf，例如：

INFLUX_TOKEN=mytoken
