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¶
- -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.
- -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.
- -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).
