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 https://github.com/mingrammer/flog.git
brew install flog
Download gzip file from Github Releases according to your OS. Then, copy the unzipped executable to under system path.
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 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)
-p, --split-by integer Split the logs by this value in lines or bytes.
When "number" is set, it specifies the maximum number of lines for a log file.
When "bytes" is set, it specifies the maximum size of a log file.
-w, --overwrite [Warning] This will overwrite the existing file with new created logs.
# 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
