NAME¶

extractvectors — Vector Extraction Tool for OMNeT++ Vector Files

SYNOPSIS¶

DESCRIPTION¶

extractvectors is an extraction tool for vectors written by OMNeT++ to a data table. ExtractVectors supports on-the-fly BZip2 decompression and compression.

ARGUMENTS¶

The following arguments may be provided:

[input_file]

The name of the input vector file.

[output_file]

The name of the output data table to be created.

[[!]vector_name_prefix]

Name prefix of vectors to be extracted. Multiple vector name prefixes may be specified. If no name prefix is given, all vectors will be extracted. A "!" in front of the name turns vector splitting for this prefix on (see --split option below).

-c level | --compress level

Sets the BZip2 compression level; 1=none, 9=highest (default).

-s separator | --separator separator

Sets the separator for the tables. Default: tabulator character (i.e. $'').

-l | --line-numbers

Add line numbers into the output table files, as usual for GNU R.

-n | --no-line-numbers

Do not add line numbers into the output table files, as usual for CSV (default).

-p | --split

Try to split the vector name ending in a number into the name part as well as the number. A vector output table is then generated for the name part, with the corresponding number in table column "Split". Example: Vectors "Throughput 1", ..., "Throughput 9" will be written into output table as vector column "Throughput", the number will be in table column "Split". --split is a global option and applies to all vector name prefixes provided. To use vector name splitting for just a single prefix, prepend the prefix with "!".

-a | --no-split

Turns vector splitting off (default).

-q | --quiet

Do not print verbose status information.

-h | --help

Prints command help.

-v | --version

Prints program version.

EXIT STATUS¶

The extractvectors tool exits with 0 on success, and >0 in case of an error.

EXAMPLE¶

Consider an OMNeT++ vector file containing the vectors "Slow Start Threshold <assoc>:<path>" and "Congestion Window <assoc>:<path>", contained with a lot of other vectors in the BZip2-compressed vector file results.vec.bz2. ExtractVectors can be used to extract all vectors beginning with "Slow Start Threshold" or "Congestion Window" into a BZip2-compressed data table results.data.bz2 by the following command:
extractvectors results.vec.bz2 results.data.bz2 \
"Slow Start Threshold" \
"Congestion Window"
For each vector entry, an output line containing time (Time), event number (Event), object name (Object), vector name (Vector), name split parameter (Split), and the vector value (Value) will be created.
Example:
Time Event Object Vector Split Value
0.003672 174 "net.client[0].sctp" "Slow Start Threshold 2:Total" "" 10000000
0.003672 174 "net.client[0].sctp" "Slow Start Threshold 2:Total" "" 10000000
0.003672 174 "net.client[0].sctp" "Congestion Window 2:Total" "" 4380
0.003672 174 "net.client[0].sctp" "Congestion Window 2:Total" "" 8760
0.003913 238 "net.server[0].sctp" "Slow Start Threshold 4:Total" "" 10000000
0.003913 238 "net.server[0].sctp" "Slow Start Threshold 4:Total" "" 10000000
0.003913 238 "net.server[0].sctp" "Congestion Window 4:Total" "" 3000
0.003913 238 "net.server[0].sctp" "Congestion Window 4:Total" "" 6000
