With

Telegraf 1.15.3 (git: HEAD fac81815)

and same config all works fine.

Reverting back to 1.15.4 fixed this for me too.

Can confirm this issues. Our +200 Server spontaneously fail the telegraf health check with that issue. The fail is not persistent so few hosts recover, few hosts fail that check. The message is, however, true. There is no file in proc with that id so i wonder why telegraf wants to check that.

this is fixed now, and will be in the next nightly build, and 1.16.1 when it releases.
