@example @c man begin SYNOPSIS usage: kvm_stat [OPTION]... @c man end @end example @c man begin DESCRIPTION kvm_stat prints counts of KVM kernel module trace events. These events signify state transitions such as guest mode entry and exit. This tool is useful for observing guest behavior from the host perspective. Often conclusions about performance or buggy behavior can be drawn from the output. The set of KVM kernel module trace events may be specific to the kernel version or architecture. It is best to check the KVM kernel module source code for the meaning of events. Note that trace events are counted globally across all running guests. @c man end @c man begin OPTIONS @table @option @item -1, --once, --batch run in batch mode for one second @item -l, --log run in logging mode (like vmstat) @item -t, --tracepoints retrieve statistics from tracepoints @item -d, --debugfs retrieve statistics from debugfs @item -f, --fields=@var{fields} fields to display (regex) @item -h, --help show help message @end table @c man end @ignore @setfilename kvm_stat @settitle Report KVM kernel module event counters. @c man begin AUTHOR Stefan Hajnoczi @c man end @c man begin SEEALSO perf(1), trace-cmd(1) @c man end @end ignore
