Connect to URI given. The default is to connect to the Xen
hypervisor.
+ To connect to QEMU/KVM you would normally do *-c qemu:///system*
+
+ To connect to libvirtd on a remote machine you would normally do *-c
+ xen://host/*
+
+ Full details on connection URIs is available at
+ <http://libvirt.org/uri.html>
+
-d delay
Set the delay between screen updates in seconds. The default is 3.0
seconds. You can change this while virt-top is running by pressing
the program was compiled (see *README* file in the source
distribution for details).
+ To save space you can compress your CSV files (if your shell
+ supports this feature, eg. *bash*):
+
+ virt-top --csv >(gzip -9 > output.csv.gz)
+
+ You can use a similar trick to split the CSV file up. In this
+ example the CSV file is split every 1000 lines into files called
+ *output.csv.00*, *output.csv.01* etc.
+
+ virt-top --csv >(split -d -l 1000 - output.csv.)
+
--no-csv-cpu
Disable domain CPU stats in CSV output.
Script mode. There will be no user interface. This is most useful
when used together with the *--csv* and *-n* options.
+ --end-time time
+ The program will exit at the *time* given.
+
+ The time may be given in one of the following formats:
+
+ *YYYY-MM-DD HH:MM:SS*
+ End time is the date and time given.
+
+ *HH:MM:SS*
+ End time is the time given, today.
+
+ *+HH:MM:SS*
+ End time is HH hours, MM minutes, SS seconds in the future
+ (counted from the moment that program starts).
+
+ *+secs*
+ End time is *secs* seconds in the future.
+
+ For example to run the program for 3 minutes you could do:
+
+ virt-top --end-time +00:03:00
+
+ or:
+
+ virt-top --end-time +180
+
+ Not every version of virt-top supports this option - it depends how
+ the program was compiled (see *README* file in the source
+ distribution for details).
+
--help
Display usage summary.
script *true|false*
Sets script mode.
+ end-time *time*
+ Set the time at which the program exits. See above for the time
+ formats supported.
+
overwrite-init-file *false*
If set to *false* then the *W* key will not overwrite the init file.
this behaviour may change in the future.
