Logging setup for FastAPI

This logging setup configures Structlog to output pretty logs in development, and JSON log lines in production.

Then, you can use Structlog loggers or standard logging loggers, and they both will be processed by the Structlog pipeline (see the hello() endpoint for reference). That way any log generated by your dependencies will also be processed and enriched, even if they know nothing about Structlog!

Requests are assigned a correlation ID with the asgi-correlation-id middleware (either captured from incoming request or generated on the fly). All logs are linked to the correlation ID, and to the Datadog trace/span if instrumented. This data "global to the request" is stored in context vars, and automatically added to all logs produced during the request thanks to Structlog. You can add to these "global local variables" at any point in an endpoint with `structlog.contextvars.bind_contextvars(custom

Remote PCAP

Requirements:

• Windows 10, or newer
• Wireshark 3.0, or newer (installed with Sshdump component)
• WLAN Pi or SBC (assumption is rpcapd is setup and running)
• SSH Client

Can leverage rpcap (remote packet capture) protocol supported by Wireshark to capture raw wireless frames from the WLAN NIC used by the WLAN Pi. This can be leveraged to do a packet capture from a WLAN Pi in a remote location.

ZeroTier (ZT) is open source and free to use for most cases (commercial/proprietary use makes it not free).

It's a network virtualization platform that lets you connect to your devices with automatic end-to-end encryption. Think of it conceptually like a VPN, SDN, and SD-WAN all in one.

Getting Started

1. Create and verify an account over at https://my.zerotier.com/

2. Create a network https://my.zerotier.com/network
