.SH "NAME"
virt\-top \- 'top'\-like utility for virtualization stats
.SH "SUMMARY"
.IX Item "-c uri or --connect uri"
Connect to \s-1URI\s0 given. The default is to connect to the Xen
hypervisor.
+.Sp
+To connect to \s-1QEMU/KVM\s0 you would normally do \fI\-c qemu:///system\fR
+.Sp
+To connect to libvirtd on a remote machine you would normally do
+\&\fI\-c xen://host/\fR
+.Sp
+Full details on connection URIs is available at
+<http://libvirt.org/uri.html>
.IP "\fB\-d delay\fR" 4
.IX Item "-d delay"
Set the delay between screen updates in seconds.
Not every version of virt-top supports \s-1CSV\s0 output \- it depends how the
program was compiled (see \fI\s-1README\s0\fR file in the source distribution
for details).
+.Sp
+To save space you can compress your \s-1CSV\s0 files (if your shell supports
+this feature, eg. \fIbash\fR):
+.Sp
+.Vb 1
+\& virt\-top \-\-csv >(gzip \-9 > output.csv.gz)
+.Ve
+.Sp
+You can use a similar trick to split the \s-1CSV\s0 file up. In this example
+the \s-1CSV\s0 file is split every 1000 lines into files called
+\&\fIoutput.csv.00\fR, \fIoutput.csv.01\fR etc.
+.Sp
+.Vb 1
+\& virt\-top \-\-csv >(split \-d \-l 1000 \- output.csv.)
+.Ve
.IP "\fB\-\-no\-csv\-cpu\fR" 4
.IX Item "--no-csv-cpu"
Disable domain \s-1CPU\s0 stats in \s-1CSV\s0 output.
To send error messages to syslog you can do:
.Sp
.Vb 1
-\& virt-top --debug >(logger -t virt-top)
+\& virt\-top \-\-debug >(logger \-t virt\-top)
.Ve
.Sp
See also \s-1REPORTING\s0 \s-1BUGS\s0 below.
.IP "\fB\-\-init\-file filename\fR" 4
.IX Item "--init-file filename"
Read \fIfilename\fR as the init file instead of the default which is
-\&\fI$HOME/.virt\-toprc\fR. See also \s-1INIT\s0 \s-1FILE\s0 below.
+\&\fI\f(CI$HOME\fI/.virt\-toprc\fR. See also \s-1INIT\s0 \s-1FILE\s0 below.
.IP "\fB\-\-no\-init\-file\fR" 4
.IX Item "--no-init-file"
Do not read any init file.
.IX Item "--script"
Script mode. There will be no user interface. This is most useful
when used together with the \fI\-\-csv\fR and \fI\-n\fR options.
+.IP "\fB\-\-end\-time time\fR" 4
+.IX Item "--end-time time"
+The program will exit at the \fItime\fR given.
+.Sp
+The time may be given in one of the following formats:
+.RS 4
+.IP "\fIYYYY-MM-DD \s-1HH:MM:SS\s0\fR" 4
+.IX Item "YYYY-MM-DD HH:MM:SS"
+End time is the date and time given.
+.IP "\fI\s-1HH:MM:SS\s0\fR" 4
+.IX Item "HH:MM:SS"
+End time is the time given, today.
+.IP "\fI+HH:MM:SS\fR" 4
+.IX Item "+HH:MM:SS"
+End time is \s-1HH\s0 hours, \s-1MM\s0 minutes, \s-1SS\s0 seconds in the future (counted
+from the moment that program starts).
+.IP "\fI+secs\fR" 4
+.IX Item "+secs"
+End time is \fIsecs\fR seconds in the future.
+.RE
+.RS 4
+.Sp
+For example to run the program for 3 minutes you could do:
+.Sp
+.Vb 1
+\& virt\-top \-\-end\-time +00:03:00
+.Ve
+.Sp
+or:
+.Sp
+.Vb 1
+\& virt\-top \-\-end\-time +180
+.Ve
+.Sp
+Not every version of virt-top supports this option \- it depends how the
+program was compiled (see \fI\s-1README\s0\fR file in the source distribution
+for details).
+.RE
.IP "\fB\-\-help\fR" 4
.IX Item "--help"
Display usage summary.
.IP "\fBscript\fR \fItrue|false\fR" 4
.IX Item "script true|false"
Sets script mode.
+.IP "\fBend-time\fR \fItime\fR" 4
+.IX Item "end-time time"
+Set the time at which the program exits. See above for the
+time formats supported.
.IP "\fBoverwrite-init-file\fR \fIfalse\fR" 4
.IX Item "overwrite-init-file false"
If set to \fIfalse\fR then the \fIW\fR key will not overwrite the
