Telegraf tail doesn't send data to InfluxDB v2 in a bucket

InfluxDB 2
, ,
1

Hello our team has used telegraf - influxdb v2 - grafana for a long time and decided to use tail plugin this time for nginx access.log

I added tail plugin options in the conf file and restarted telegraf and telegraf.log showed it was successful.(and tail plugin was loaded) However, I can’t see any tail data in the _measurement on InfluxDB UI, while I can see ipmi_sensor data that we have used for a long time. So I assume that telegraf doesn’t send tail plugin data while it does ipmi plugin data.

Could I ask for any help?
P.S. one thing strange is that the telegraf server can connect to the influxdb server with telnet, but it doesn’t get any reponse with ping request.

Hi,

The first step is to look at the Telegraf logs themself and see what it is indicating. It would be good to see if there are any errors or issues coming up.

Second, I would use the [[outputs.file]] output to see what metrics are collected by Telegraf. This will print them to stdout or your log file. That way you can confirm you are getting data from the tail plugin.
