Re: [libvirt] [PATCHv2 2/2] Introduce command 'virsh domstats --memory' for reporting memory BW

Introduce an option '--memory' for showing memory related information. The memory bandwidth infomatio is listed as: Domain: 'libvirt-vm' memory.bandwidth.monitor.count=4 memory.bandwidth.monitor.0.name=vcpus_0-4 memory.bandwidth.monitor.0.vcpus=0-4 memory.bandwidth.monitor.0.node.count=2 memory.bandwidth.monitor.0.node.0.id=0 memory.bandwidth.monitor.0.node.0.bytes.total=10208067584 memory.bandwidth.monitor.0.node.0.bytes.local=4807114752 memory.bandwidth.monitor.0.node.1.id=1 memory.bandwidth.monitor.0.node.1.bytes.total=8693735424 memory.bandwidth.monitor.0.node.1.bytes.local=5850161152 memory.bandwidth.monitor.1.name=vcpus_7 memory.bandwidth.monitor.1.vcpus=7 memory.bandwidth.monitor.1.node.count=2 memory.bandwidth.monitor.1.node.0.id=0 memory.bandwidth.monitor.1.node.0.bytes.total=853811200 memory.bandwidth.monitor.1.node.0.bytes.local=290701312 memory.bandwidth.monitor.1.node.1.id=1 memory.bandwidth.monitor.1.node.1.bytes.total=406044672 memory.bandwidth.monitor.1.node.1.bytes.local=229425152 Signed-off-by: Wang Huaqiang <huaqiang.wang(a)intel.com&gt; --- docs/manpages/virsh.rst | 22 ++++++- include/libvirt/libvirt-domain.h | 1 + src/libvirt-domain.c | 21 +++++++ src/qemu/qemu_driver.c | 103 +++++++++++++++++++++++++++++++ tools/virsh-domain-monitor.c | 7 +++ 5 files changed, 152 insertions(+), 2 deletions(-)
