VNSTAT.CONF(5) User Manuals VNSTAT.CONF(5)NAMEvnstat.conf - vnStat configuration file
SYNOPSIS
/etc/vnstat.conf
DESCRIPTIONvnstat(1), vnstati(1) and vnstatd(1) all use the same configuration
file for storing configuration data. Some of the settings are common
for all three programs. The file contains keyword-argument pairs, one
per line. Lines starting with Arguments may optionally be enclosed in
double quotes (") in order to represent arguments containing spaces.
Arguments can be padded with spaces or tabulator characters. A hard‐
coded default value will be used if a keyword can't be found from the
configuration file.
COMMON KEYWORDS
BootVariation
Time in seconds how much the boot time reported by system kernel
can variate between updates.
CheckDiskSpace
Enable or disable the checking of at least some free disk space
before a database write. 1 = enabled, 0 = disabled.
DatabaseDir
Specifies the directory where interface databases are to be
stored. A full path must be given and a leading '/' isn't
required.
DayFormat, MonthFormat, TopFormat
Formatting of date in available outputs. Uses the same format as
date(1). (vnstat and vnstati only)
Interface
Default interface used when no other interface is specified on
the command line. (vnstat and vnstati only)
Locale Locale setting to be used for prints. This replaces the LC_ALL
environment variable. Set to "-" in order to use the system
default value. (vnstat and vnstati only)
MaxBandwidth
Maximum bandwidth for all interfaces. If the counted traffic
exceeds the given value then the data is assumed to be invalid
and rejected. Set to 0 in order to disable the feature. (vnstat
and vnstatd only)
MaxBW Same as MaxBandwidth but can be used for setting individual lim‐
its for selected interfaces. The name of the interface is speci‐
fied directly after the MaxBW keyword without spaces. For exam‐
ple MaxBWeth0 for eth0 and MaxBWppp0 for ppp0. (vnstat and
vnstatd only)
MonthRotate
Day of month that months are expected to change. Usually set to
1 but can be set to alternative values for example for tracking
monthly billed traffic where the billing period doesn't start on
the first day. (vnstat and vnstatd only)
OutputStyle
Modify the content and style of text outputs. 0 = minimal and
narrow output for terminal with limited width, 1 = normal output
with bar column visible, 2 = same as 1 except rate is visible in
summary and weekly outputs, 3 = rate column is visible in all
outputs where it is supported. (vnstat and vnstati only)
QueryMode
Default query mode when no parameters are given. 0 = normal, 1 =
days, 2 = months, 3 = top10, 4 = dumpdb, 5 = short, 6 = weeks, 7
= hours and 8 = xml. (vnstat only)
RateUnit
Select which unit is used when traffic rate is visible. 0 =
bytes, 1 = bits. (vnstat and vnstati only)
RXCharacter, TXCharacter
Character used for representing the percentual share of received
and transmitted traffic in daily output. (vnstat only)
RXHourCharacter, TXHourCharacter
Character used for representing the percentual share of received
and transmitted traffic in hourly output. (vnstat only)
Sampletime
Defines how many seconds the -tr option will sample traffic.
(vnstat only)
TrafficlessDays
Log days without any traffic to daily list. 1 = enabled, 0 =
disabled. (vnstat and vnstatd only)
UnitMode
Select how units are prefixed. 0 = IEC standard prefixes
(KiB/MiB/GiB/TiB), 1 = old style binary prefixes (KB/MB/GB/TB).
(vnstat and vnstati only)

PollInterval
How often in seconds interfaces are checked for status changes.
SaveInterval
How often in minutes cached interface data is saved to file.
SaveOnStatusChange
