Couldn't resolve addr or pid <pid> to TCPAddress

root@xxx-server# gops stack 19401
Couldn't resolve addr or pid 19401 to TCPAddress: couldn't get port for PID 19401: open /root/.config/gops/19401: no such file or directory

The process 19401 also needs to run gops agent

Just wondering, if gops agent added into application, will it affect performance?
