mTLS for a desktop monitoring tool (and why you shouldn't use a cloud)

Somewhere in the last ten years, “I want to see the CPU graph on my other machine” quietly turned into a SaaS product with an agent, a relay server, an account, and a pricing page, and the whole arrangement is strange when you sit with it for a minute, because the two machines are yours, the data is a stream of numbers about hardware you own, and the only thing the cloud in the middle is actually contributing is a rendezvous point and a monthly invoice. LinSight’s answer to remote monitoring is that there is no middle: the daemon already serves everything over a Unix socket on the local machine, so the remote feature is a small binary called linsight-tunnel that pipes those socket bytes over a mutually authenticated TLS connection to another linsight-tunnel on your desktop, where it re-materializes as a local Unix socket that the GUI, the CLI, and the Prometheus scraper connect to as if the daemon were sitting right there.
