saz-tools

saz-tools

Tools for parsing SAZ files (Fiddler logs) and either printing their content on the console, or viewing them on a web page and offering basic analysis and export. Try the on-line version of the SAZ Viewer.

Installation

If you have Go installed, using go get to install a global module is the easiest way:

$ GO111MODULE=off go get -u github.com/prantlf/saz-tools/...

If you have Node.js installed, you can use NPM, Yarn or PNPM to install a global module easily:

npm i -g saz-tools
yarn global add saz-tools
pnpm i -g saz-tools

If you have the standard sh available, you can use the installation script from GoBinaries:

curl -sf https://gobinaries.com/prantlf/saz-tools | sh

If you manage your software using Homebrew, you can install the tools using their formula:

brew install prantlf/tap/saz-tools

Windows users can install using the Scoop manifest:

scoop bucket add prantlf https://github.com/prantlf/scoop-bucket.git
scoop install prantlf/saz-tools

Ubuntu users can install the Snap package:

sudo snap install saz-tools

If you work on Linux which uses deb or rpm packages, you can download and install a package from GitHub releases.

Or download and unpack a binary archive for your operation system from GitHub releases directly.

If you want to install a specific commit or the latest master and you do not have the development environment to build it, you can use Docker to build:

git clone https://github.com/prantlf/saz-tools.git
cd saz-tools
docker run --rm -it -v ${PWD}:/work -w /work \
  prantlf/golang-make-nodejs-git clean prepare all DOCKER=1

If you want to run the tools using Docker images, see the instructions below.

API

• parser.ParseFile(fileName string) ([] parser.Session, error)
• parser.ParseReader(reader ReaderAt, size int64) ([] parser.Session, error)
• analyzer.Analyze(sessions [] parser.Session) ([] analyzer.Session, error)
• dumper.Dump(sessions [] parser.Session) error

import (
  "github.com/prantlf/saz-tools/pkg/analyzer"
  "github.com/prantlf/saz-tools/pkg/dumper"
  "github.com/prantlf/saz-tools/pkg/parser"
)

func main() {
  rawSessions, _ := parser.ParseFile("foo.saz")
  fineSessions, _ := analyzer.Analyze(rawSessions)
  dumper.Dump(rawSessions)
}

Build

You need Go, Make, Node.js, NPM and Patch to build all parts of this module from sources.

# Install build tools only once:
make prepare
# Build all targets:
make
# Dump a SAZ file analysis on the console:
make run-dump SAZ="..."
# Start a SAZ file viewer as a browser application with bundled assets:
make run-serve
# Start a SAZ file viewer as a browser application with filesystem assets:
make debug-serve
# Remove all build output:
make clean

Docker

The sazdump image and the sazserve image allows you to execute the tools described above. They are built automatically on the top of the tag latest from the scratch image.

The following tags are available for the prantlf/sazdump and prantlf/sazserve images:

• latest

Download the latest image to your disk:

docker pull prantlf/sazdump
docker pull prantlf/sazserve
# or
docker pull prantlf/sazdump:latest
docker pull prantlf/sazserve:latest

Print usage description with command-line parameters:

docker run --rm -it prantlf/sazdump -h

For example, dump the context of the foo.saz file:

docker run --rm -it -v ${PWD}:/work -w /work sazdump foo.saz

Or start the browser application to analyse SAZ files on your machine:

docker run --rm -it -p 7000:7000 sazserve

You can also put sazdump and sazserve scripts to PATH:

#!/bin/sh
docker run --rm -it -v ${PWD}:/work -w /work sazdump "$@"

#!/bin/sh
docker run --rm -it -v -p 7000:7000 sazserve

and execute then from any location by supplying parameters to it, for example:

sazdump foo.saz
sazserve

Local images are built as sazdump and sazserve and they are pushed to the docker hub as prantlf/sazdump:latest and prantlf/sazserve:latest.

# Check the Dockerfiles:
make docker-lint
# Build new local images:
make docker-build
# Print the help for the SAZ file dumper:
make docker-run-help
# Dump a SAZ file analysis on the console:
make docker-dump-example SAZ="..."
# Start a SAZ file viewer as a web application:
make docker-serve-example
# Tag local images for pushing:
make docker-tag
# Login to the docker hub:
make docker-login
# Push local images to the docker hub:
make docker-push
