go-sshproc

About

This library is adds the functionality to get performance information from procfs to go-sshlib. Use an sftp client to obtain performance information by retrieving information such as /proc. For this reason, the ssh connection destination must be a UNIX-like OS such as Linux.

Some of the references and code have been changed in order to have almost the same usability as goprocinfo.

Usage

See GoDoc reference.
