tntnet.properties - configuration-file for tntnet (8)
tntnet(8) uses cxxtools for logging and is configured in the
Because cxxtools is a meta-logging-library, which can be compiled to
use different logging-libraries, the content of tntnet.properties is
dependend of the underlying logging-library. Cxxtool has a built-in
logging-library as default, which is documented here.
The format of tntnet.properties is line-based. A line consists of a
variable-name followed by a equals-symbol and a value. Lines, which
does not follow this format and lines, which start with a hash (#), are
ignored. It is recomended to prefix non-empty comments with a hash to
make clear, that it is a comment.
The logging-library has 5 levels for logging: fatal, error, warn, info
and debug. Fatal has the highers priority and "debug" the lowest.
Each log-message has a category. Categories are hierarchical. Names
of subcategories are devided by a dot.
Each log-message has a level and a category. If the level of the
message is higher or equal to the level of the category, the message is
logged. To assign a level to a category put a line with the word
"logger", a dot, the category, the symbol "=" and the category into
tntnet.properties. Only the first letter of the value is checked and
case is ignored, so e.g. info can be specified with INFO, info, I or
even ixxxx. If no level is specified for the current category, the
upper category is checked. If nothing is found, the default level is
used. The default level is specified by the variable "rootLogger". If
no rootLogger is specified, the level error is used.
If nothing else is specified, log-messages are printed to standard-
output. To redirect output to a file, specify the filename with the
The cxxtools-logger can limit the size of the log-file by rolling log-
files. If the limit is reached, the current file is renamed by
appending ".1" to it. If there is already a file with that name, this
file is renamed to "*.2" and so on, until the maximum backupfile limit
is reached. The oldest file is deleted then. To specify the maximum
file size, set the variable maxfilesize. The value specified here can
be postfixed with 'k' or 'M' to specify kBytes or MBytes. The maximum
fileindex backed up is set with maxbackupindex.
Since writing the file can take some time, output can be buffered and
written physically in regular intervals. The interval is specified in
milliseconds with the variable flushdelay. The logging-library starts
a background-thread, which flushes the buffer regulary. This improves
logging-speed significantly. The problem is, that a background-thread
is used, which consumes resources and if the program crashes, the most
recent log-messages might not be in the file.
Log-messages can be sent to another host in the network with udp. This
is done by specifying a hostname and a port with the variable host.
The value must be a hostname, followed by a ':' and a port. Each log-
message is sent in a single udp-message.
