DESCRIPTION
The purpose of
vnstati
is to provide image output support for statistics collected using
vnstat(1).
The image file format is limited to png. All basic outputs
of vnStat are supported excluding live traffic features. The image
can be outputted either to a file or to standard output.
OPTIONS
- --altdate
-
Use alternative date and time text location. The date and time text will be moved
from the upper right header section to the lower left corner. This option
will have no effect if
-nh, --noheader
has been selected.
- -c, --cache time
-
Update output file only if at least
time
minutes have passed since the previous file update. This option is ignored if
stdout is used as output.
- --config file
-
Use
file
as configuration file instead of using normal configuration file search
functionality.
- -d, --days
-
Output traffic statistics on a daily basis for the last 30 days.
- --dbdir directory
-
Use
directory
as database directory instead of using the directory specified in the configuration
file or the hardcoded default if no configuration file is available.
- --headertext text
-
Show
text
in image header section instead of automatically generated interface identification.
text
is limited to 64 characters and may not get completely shown if longer than the width of
the image. Use with
--altdate
if maximal space is needed. This option will have no effect if
-nh, --noheader
has been selected.
- -h, --hours
-
Output traffic statistics on a hourly basis for the last 24 hours.
- -hs, --hsummary
-
Output traffic summary including hourly data using a horizontal layout.
- -i, --iface interface
-
Use
interface
instead of default or configured interface.
- --locale locale
-
Use
locale
instead of using the locale setting specified in the configuration file or the system
default if no configuration file is available.
- -m, --months
-
Output traffic statistics on a monthly basis for the last 12 months.
- -ne, --noedge
-
Remove darker edges from around the image.
- -nh, --noheader
-
Remove header containing title and update time. Time of the previous update
will still be visible in the lower right corner using a less visible color.
- -nl, --nolegend
-
Remove legend containing rx and tx color mapping information from the image.
- -o, --output file
-
Write png image to
file
and exit. Output can be directed to stdout by giving "-" as filename.
- -ru, --rateunit
-
Change the configured rate unit. If rate has been configured to be shown in
bytes then rate will be shown in bits if this option is present. In the same
way, if rate has been configured to be shown in bits then rate will be shown
in bytes when this option is present. Alternatively 0 or 1 can be given as
parameter for this option in order to select between bytes (0) and bits
(1) regardless of the configuration file setting.
- --style number
-
Modify the content and style of outputs. Setting
number
to 3 will show average traffic rate in all outputs where it is supported.
Other values will show bar graphics instead.
- -s, --summary
-
Output traffic statistics summary.
- -t, --top10
-
Output all time top 10 traffic days.
- --transparent
-
Toggle background color transparency depending of the TransparentBg setting
in the configuration file. Alternatively 0 or 1 can be given as parameter
for this option in order to either disable (0) or enable (1) transparency
regardless of the configuration file setting.
- -v, --version
-
Show current version.
- -vs, --vsummary
-
Output traffic summary including hourly data using a vertical layout.
- -?, --help
-
Show a command option summary.
FILES
- /var/lib/vnstat/
-
Default database directory. Files are named according to the monitored interfaces.
- /etc/vnstat.conf
-
Config file that will be used unless
$HOME/.vnstatrc
exists. See
vnstat.conf(5)
for more information.
EXAMPLES
- vnstati -s -i eth0 -o /tmp/vnstat.png
-
Output traffic summary for interface eth0 to file /tmp/vnstat.png.
- vnstati -vs -i eth0+eth1+eth2 -o /tmp/vnstat.png
-
Output traffic summary with hourly data under the normal summary for a merge of
interfaces eth0, eth1 and eth2 to file /tmp/vnstat.png.
- vnstati -h -c 15 -o /tmp/vnstat_h.png
-
Output hourly traffic statistics for default interface to file /tmp/vnstat_h.png
if the file has not been updated within the last 15 minutes.
- vnstati -d -ne -nh -o -
-
Output daily traffic statistics without displaying the header section and edges
for default interface to standard output (stdout).
- vnstati -m --config /home/me/vnstat.cfg -i -o -
-
Output monthly traffic statistics for default interface specified in configuration
file /home/me/vnstat.cfg to standard output (stdout).
RESTRICTIONS
Depending on the built-in fonts provided by the GD library, not all characters
may end up shown correctly when a UTF-8 locale is used.
Using long date output formats may cause misalignment in shown columns if the
length of the date exceeds the fixed size allocation.
