hi,titilambert @titilambert .I have some problems about this.It seems to be related to "Add SIGHUP support to reload telegraf config",when I use tail input plugin to collect logs metrics ,start is well ,but after one hour or two 2 hour.The telegraf process is still there, but it cannot collect logs : )..and the telegrafa log is:
nohup: ignoring input
2018-04-19T12:19:02Z I! Database creation failed: Response Error: Status Code [405], expected [200], []

.....my start telegraf way is:
nohup telegraf --config telegraf.config > out.log 2>&1 &

that is all . thanks
P.S. sorry for my poor english ~:)

@Xin-T I don't think this related to the SIGHUP code, have you tried watch_method = "poll" on the tail plugin? If this doesn't help you can open an issue on the InfluxData Community site.
