Telegraf

Hello2*. I have a problem with inputs.dpdk.
Telegraf 1.31.3.
config:

[[inputs.dpdk]]
  socket_path =  "/var/run/dpdk/rte/dpdk_telemetry.v2"
  device_types = ["ethdev"]
  interval = "10s"
  socket_access_timeout = "10s"

but after run telegraf I have error:
no active sockets connections present
but

root@trex:~# netstat | grep dpdk
unix  2      [ ]         DGRAM                    3412513  /var/run/dpdk/rte/mp_socket
unix  3      [ ]         SEQPACKET  CONNECTED     3755265  /var/run/dpdk/rte/dpdk_telemetry.v2

and dpdk-telemetry.py show data from socket.

root@trex:/opt/usertool# python3 dpdk-telemetry.py

Are you running Telegraf as root? See this comment in the readme:

Since DPDK will most likely run with root privileges, the socket
telemetry interface exposed by DPDK will also require root access […]

Unfortunately, I can’t verify it.
It was necessary to solve it urgently. I put the version telegraf_1.26.0-1_amd64 with it, he saw the socket and said /var/run/dpdk/rte/dpdk_telemetry.v2: permission denied Then, i did:

sed -i ‘s/User=telegraf/User=root/g’ /usr/lib/systemd/system/telegraf.service
systemctl daemon-reload
systemctl restart telegraf

And everything worked. Thank You!
