NAME


vnstat.conf - vnStat configuration file

SYNOPSIS


/etc/vnstat.conf

DESCRIPTION


vnstat(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 '#' and empty lines are interpreted as comments and not processed. 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 hardcoded 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 limits for selected interfaces. The name of the interface is specified directly after the MaxBW keyword without spaces. For example 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)

UseFileLocking
Enable or disable the use of file locking during database access. Disabling file locking may cause database corruption if several processes are trying to write to the file at the same time.

PollInterval
How often in seconds interfaces are checked for status changes.

SaveInterval

SaveOnStatusChange
