vlt Launches "reproduce": A New Tool Challenging the Limits of Package Provenance
vlt's new "reproduce" tool verifies npm packages against their source code, outperforming traditional provenance adoption in the JavaScript ecosystem.
go.etcd.io/etcd/tools/rw-heatmaps/v3
etcd/tools/rw-heatmaps
is the mixed read/write performance evaluation tool for etcd clusters.
Install the tool by running the following command from the etcd source directory.
$ go install -v ./tools/rw-heatmaps
The installation will place executables in the $GOPATH/bin. If $GOPATH environment variable is not set, the tool will be installed into the $HOME/go/bin. You can also find out the installed location by running the following command from the etcd source directory. Make sure that $PATH is set accordingly in your environment.
$ go list -f "{{.Target}}" ./tools/rw-heatmaps
Alternatively, instead of installing the tool, you can use it by simply running the following command from the etcd source directory.
$ go run ./tools/rw-heatmaps
To get a mixed read/write performance evaluation result:
# run with default configurations and specify the working directory
$ ./rw-benchmark.sh -w ${WORKING_DIR}
rw-benchmark.sh
will automatically use the etcd binary compiled under etcd/bin/
directory.
Note: the result CSV file will be saved to current working directory. The working directory is where etcd database is saved. The working directory is designed for scenarios where a different mounted disk is preferred.
To generate two images (read and write) based on the benchmark result CSV file:
# to generate a pair of read & write images from one data csv file
$ rw-heatmaps ${CSV_FILE} -t ${IMAGE_TITLE} -o ${OUTPUT_IMAGE_NAME}
To generate two images (read and write) showing the performance difference from two result CSV files:
# to generate a pair of read & write images from one data csv file
$ rw-heatmaps ${CSV_FILE1} ${CSV_FILE2} -t ${IMAGE_TITLE} -o ${OUTPUT_IMAGE_NAME}
To see the available options use the --help
option.
$ rw-heatmaps --help
rw-heatmaps is a tool to generate read/write heatmaps images for etcd3.
Usage:
rw-heatmaps [input file(s) in csv format] [flags]
Flags:
-h, --help help for rw-heatmaps
-f, --output-format string output image file format (default "jpg")
-o, --output-image-file string output image filename (required)
-t, --title string plot graph title (required)
--zero-centered plot the improvement graph with white color represents 0.0 (default true)
