A fake log generator for common log formats
flog is a fake log generator for common log formats such as apache-common, apache error and RFC3164 syslog.
It is useful for testing some tasks which require log data like amazon kinesis log stream test.

go get github.com/mingrammer/flogIt is recommended to also run dep ensure to make sure that the dependencies are in the correct versions.
Using homebrew
brew tap mingrammer/flog
brew install flog
Download gzip file from Github Releases according to your OS. Then, copy the unzipped executable to under system path.
Using docker
docker run -it --rm mingrammer/flog
There are useful options. (flog --help)
Options:
-f, --format string Choose log format. ("apache_common"|"apache_combined"|"apache_error"|"rfc3164") (default "apache_common")
-o, --output string Output filename. Path-like is allowed. (default "generated.log")
-t, --type string Log output type. ("stdout"|"log"|"gz") (default "stdout")
-n, --number integer Number of lines to generate.
-b, --bytes integer Size of logs to generate (in bytes).
"bytes" will be ignored when "number" is set.
-s, --sleep numeric Sleep interval time between lines (in seconds). It does not actually sleep every log generation.
-p, --split-by integer Set the maximum number of lines or maximum size in bytes of a log file.
With "number" option, the logs will be split every time a certain number of lines is reached.
With "bytes" option, the logs will be split every time a certain size in bytes is reached.
-w, --overwrite [Warning] Overwrite the existing log files.
-l, --loop Loop output forever until killed.# Generate 1000 lines of logs to stdout
flog
# Generate a single log file with 1000 lines of logs, then overwrite existing log file
flog -t log -w
# Generate a single log gzip file with 3000 lines of logs every 10 seconds
flog -t gz -o log.gz -n 3000 -s 10
# Generate logs up to 10MB and split the log files every 1MB in "web/log/apache.log" path with apache combined format
flog -t log -f apache_combined -o web/log/apache.log -b 10485760 -p 1048576
# Generate logs in rfc3164 format infinitely
flog -f rfc3164 -l- Completely random log generator
- Contextual random log generator
- Statistical random log generator
- Support
apache common,apache combined,apache errorandrfc3164log format - Support some other syslog formats
- Support stdout, file and gzip type of logging
