1kvm_stat(1) 2=========== 3 4NAME 5---- 6kvm_stat - Report KVM kernel module event counters 7 8SYNOPSIS 9-------- 10[verse] 11'kvm_stat' [OPTION]... 12 13DESCRIPTION 14----------- 15kvm_stat prints counts of KVM kernel module trace events. These events signify 16state transitions such as guest mode entry and exit. 17 18This tool is useful for observing guest behavior from the host perspective. 19Often conclusions about performance or buggy behavior can be drawn from the 20output. 21 22The set of KVM kernel module trace events may be specific to the kernel version 23or architecture. It is best to check the KVM kernel module source code for the 24meaning of events. 25 26OPTIONS 27------- 28-1:: 29--once:: 30--batch:: 31 run in batch mode for one second 32 33-l:: 34--log:: 35 run in logging mode (like vmstat) 36 37-t:: 38--tracepoints:: 39 retrieve statistics from tracepoints 40 41-d:: 42--debugfs:: 43 retrieve statistics from debugfs 44 45-p<pid>:: 46--pid=<pid>:: 47 limit statistics to one virtual machine (pid) 48 49-f<fields>:: 50--fields=<fields>:: 51 fields to display (regex) 52 53-h:: 54--help:: 55 show help message 56 57SEE ALSO 58-------- 59'perf'(1), 'trace-cmd'(1) 60 61AUTHOR 62------ 63Stefan Hajnoczi <stefanha@redhat.com> 64
