How to use the command 'sc_warts2json' (with examples)

The sc_warts2json command is a versatile tool used to convert warts files, which are collected using the scamper tool, into a JSON format. This conversion is crucial for data analysis and visualization because JSON is a widely used format that is easily readable and compatible with numerous data processing tools and programming languages. The conversion process retains the detailed information captured in the warts file while making it more accessible for further processing and interpretation.

Use case: Convert warts files to JSON and output the result

Code:

sc_warts2json path/to/file1.warts path/to/file2.warts

Motivation for using the example:

Converting warts files to JSON format is especially beneficial for network researchers and engineers who need to analyze and interpret vast amounts of network data collected via the scamper tool. Warts files, while efficient for data capture, are not as user-friendly when it comes to accessing individual data points or conducting in-depth analyses. The JSON format, however, is structured and easily parsed, making it the ideal choice for these tasks.

By using sc_warts2json, users can transform raw network data into a format that can be seamlessly integrated into data analysis libraries, such as Python’s pandas, or visualized using tools like JavaScript’s D3.js. This facilitates deeper insights into network behavior, performance metrics, and potential issues.

Explanation for every argument given in the command:

• sc_warts2json: This is the command used to invoke the conversion of warts files to the JSON format. It is part of the suite of tools provided by CAIDA for network measurement and analysis.

• path/to/file1.warts path/to/file2.warts: These are the arguments that specify the paths to the warts files that you want to convert. You can provide one or more warts files as arguments, separated by spaces, to convert them into JSON format. Each warts file contains network measurement data, and you can specify multiple files if you need to convert a dataset consisting of many files.

Example output:

When the command is successfully executed, the warts files are converted into JSON format, and the output might look something like this:

[
    {
        "filename": "file1.warts",
        "traces": [
            {
                "src": "192.0.2.1",
                "dst": "198.51.100.1",
                "hops": [
                    {"ttl": 1, "addr": "192.0.2.254", "rtt": 10.1},
                    {"ttl": 2, "addr": "198.51.100.6", "rtt": 20.5},
                    ...
                ]
            },
            ...
        ]
    },
    {
        "filename": "file2.warts",
        "traces": [
            {
                "src": "192.0.2.2",
                "dst": "203.0.113.1",
                "hops": [
                    {"ttl": 1, "addr": "192.0.2.253", "rtt": 11.3},
                    {"ttl": 2, "addr": "203.0.113.6", "rtt": 19.6},
                    ...
                ]
            },
            ...
        ]
    }
]

This JSON output includes detailed trace information, such as source and destination IP addresses, hop information, and round-trip time (RTT) metrics. The structured format allows for straightforward data parsing and visualization, essential for network performance analysis.

Conclusion:

The sc_warts2json command provides a critical functionality for those dealing with network measurement data. By converting warts files into the universally accepted JSON format, it simplifies the data handling process, making it easier to analyze, interpret, and visualize vital network insights. This command bridges the gap between data collection and data analysis, empowering users to make data-driven decisions more efficiently.
