The tool build a JSON model \nthat is read by Vizceral to visualize traffic.\n\n## Usage\n\nThe program's VPC FlowLogs exporter works only if the targeted instances' VPC have flow logs enabled and the logs are in CloudWatch Logs  \n\nRun: `go build` in the current directory, then run it using the parameter and environment variables configuration:\n\n* params: `./network-logger --fileowner=OWNER\n                    --out=.....vizceral-example/dist/generated.json`. This will case the `generated.json` file \n                    to be exported in the location specified by the parameter\n\n* environment variables:\n    - SOURCE: `vpc-flowlog` or `bpf-filter` - bpf-filter implementation is in progress\n    - AWS_REGIONS: comma separated AWS region values to fetch VPC flow logs from\n    - INSTANCE_IDS: comma separated EC2 instance IDs\n    - AWS_REGION: sdk region\n    - AWS_PROFILE: sdk profile \n\n\n\u003cimg src=\"https://raw.githubusercontent.com/stefanszasz/network-logger/master/assets/vizceral-1.png\" width=\"500\" /\u003e\n\n## Notes\n\n1. BPF exporter is in progress\n2.
