Are you able to get any metrics using this configuration?

According to https://github.com/influxdata/telegraf/tree/master/plugins/inputs/tail

Metrics are produced according to the data_format option. Additionally a tag labeled path is added to the metric containing the filename being tailed.

Nothing is showing here in my InfluxDBv2 installation, even though eve.json contains data :o
