[PATCH v7 7/7] migration/dirtyrate: Introduce command 'virsh domstats --dirtyrate'

Introduce command 'virsh domstats --dirtyrate' for reporting memory dirty rate information. The info is listed as: Domain: 'vm0' dirtyrate.calc_status=2 dirtyrate.calc_start_time=1534523 dirtyrate.calc_period=1 dirtyrate.megabytes_per_second=5 Signed-off-by: Hao Wang <wanghao232(a)huawei.com&gt; --- docs/manpages/virsh.rst | 16 ++++++++++++++-- tools/virsh-domain-monitor.c | 7 +++++++ 2 files changed, 21 insertions(+), 2 deletions(-) diff --git a/docs/manpages/virsh.rst b/docs/manpages/virsh.rst index 367b4bddeb..813fb0bd60 100644 --- a/docs/manpages/virsh.rst +++ b/docs/manpages/virsh.rst @@ -2219,7 +2219,7 @@ domstats domstats [--raw] [--enforce] [--backing] [--nowait] [--state] [--cpu-total] [--balloon] [--vcpu] [--interface] - [--block] [--perf] [--iothread] [--memory] + [--block] [--perf] [--iothread] [--memory] [--dirtyrate] [[--list-active] [--list-inactive] [--list-persistent] [--list-transient] [--list-running]y [--list-paused] [--list-shutoff] [--list-other]] | [domain ...] @@ -2238,7 +2238,8 @@ behavior use the *--raw* flag.
