Generating mFit report - JSON

steps-to-generate-mfit-report.md

Ssh into the machine we have the application to be analyzed.

gcloud compute ssh <machine_name> - tunnel-through-iap

Create a directory m4a and cd into it.

mkdir m4a && cd m4a

Download the latest version of the mfit assessment tool.

curl -O "https://mfit-release.storage.googleapis.com/$(curl -s https://mfit-release.storage.googleapis.com/latest)/mfit"

Make it executable.

chmod +x mfit

Download the latets version of the collector tool.

The collector tools works complimentary to the assessment tool. It collects the required data and creates a tar file to be assessed. If you have multiple machines to be assessed, you can install the collector on all of them, install the assessment tool in a host machine with ssh access to the other machines, and run the assessment from one single machine.

curl -O "https://mfit-release.storage.googleapis.com/$(curl -s https://mfit-release.storage.googleapis.com/latest)/mfit-linux-collect.sh"

Make the collector file exceutable.

chmod +x mfit-linux-collect.sh

Execute the collector.

sudo ./mfit-linux-collect.sh

Run the assessment on the tar file using mfit assess

./mfit assess sample <file-generated-after-data-collection>.tar - format json > app-mfit-report.json

Copy this report into your cloudshell and then download it into your local machine using this command –

gcloud compute scp - tunnel-through-iap \ <machine_name>:~/m4a/app-mfit-report.json ${HOME}/ cloudshell download app-mfit-report.json

You have downloaded the JSON (not so pretty) version of the report. The rest of the work is to be done in the GCP console.
