Debug full log to a file

[codebien]

Hi @Gerard,
the following topic should be still a valid reference for addressing your use case.

Print --http-debug logs into file & print all api responses in a file

You cannot open a file and write to it from inside of a k6 script, but you can redirect the k6 stderr output to a file like this: k6 run --logformat=raw --http-debug=full github.com/loadimpact/k6/samples/http_get.js 2> http_debug.txt Alternatively, you can find other approaches to debugging HTTP requests in Dump all outgoing requests in json?, including using console.warn() and such, though as you can see from that thread, there are caveats.

The next release, with a good probability, will contain a new file argument for the –log-output option, making the previous case simpler to apply. Subscribe to the k6 release page on GitHub to be notified on the next release.
