我有一個運行在 Ubuntu 20.04 上的虛擬機，我安裝了 Telegraf、InfluxDB 和 Grafana。
一切正常，除了當我嘗試讓 telegraf 在後台工作時。
手動啟動正在執行的 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! Loaded aggregators:

2021-03-14T00:02:27Z I! [agent] Config: Interval:10s, Quiet:false, Hostname:"XXXXX", Flush Interval:10s
所以到目前為止一切都很好。
但無法執行此服務（/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
User=telegraf

ExecReload=/bin/kill -HUP $MAINPID
Restart=on-failure
RestartForceExitStatus=SIGPIPE
KillMode=control-group
[Install]
WantedBy=multi-user.target
開始順利，但在檢查服務狀態後我得到：
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

InfluxDB 沒有取得任何數據，Grafana 也是如此。
誰能幫我解決這個服務問題並讓 Telegraf 在後台工作嗎？
答案1
這個資訊很難被罰款！我在這裡找到了解決方案：
https://github.com/influxdata/telegraf/issues/8395。
所以你所要做的就是將 INFLUX_TOKEN 變數加入到/etc/預設/電報例如：
INFLUX_TOKEN=mytoken
