Towertail docs
Towertail is a macOS menu-bar app. It shows live CPU, memory, disk and network values for each of your servers. It connects to the servers over SSH. Tailscale is optional.
You do not install an agent on your servers. Towertail copies a small sampler binary to each server over SSH. At each poll, Towertail runs the sampler and reads one JSON sample. The sampler does not stay in memory and does not open a port.
