2.1.3

This release mostly focuses on stability and bug fixing. For simplicity the branch profiler is merged into the master with this release (why the commit log is lengthy).

General Usage

Usage:
  kvmtop [OPTIONS]

Monitor virtual machine experience from outside on KVM hypervisor level

Application Options:
  -v, --version     Show version
  -f, --frequency=  Frequency (in seconds) for collecting metrics (default: 1)
  -r, --runs=       Amount of collection runs (default: -1)
  -c, --connection= connection uri to libvirt daemon (default: qemu:///system)
      --procfs=     path to the proc filesystem (default: /proc)
      --verbose     Verbose output, adds more detailed fields
      --cpu         enable cpu metrics
      --mem         enable memory metrics
      --disk        enable disk metrics
      --net         enable network metrics
      --io          enable io metrics (requires root)
  -b, --batch       [DEPRECATED: use --printer=text instead] use simple output
                    e.g. for scripts
  -p, --printer=    the output printer to use (valid printers: ncurses, text,
                    json) (default: ncurses)
