View hardware sensors remotely with GkrellM: The GNU Krell Monitors

Sometimes a perfectly good good system tool goes overlooked until a particular need arises, as in the case of GkrellM. GKrellM is a GTK program to display a single process stack of system monitors. Usually I have it running on a second monitor to keep tabs on temperatures, fan speeds and various other parameters. Recently, when running with a single monitor and with programs fullscreen, I was missing being able to glance at this tool. Gkrellm can be set to always "on top" but that is not suitable in most cases. Then I discovered gkrellmd: The GNU Krell Monitors Server! After reviewing the man pages for each, we can start a server with

where
-A <host> is the computer whose sensors you want to monitor
-P <port> is the port on <host>
-u <n> is the update interval in Hz (updates per second)
-d runs gkrellmd in the background, detached from the terminal

On the remote computer, attach to the gkrellm server with the host name and port number specified when running the server

Now I can keep an eye on the thermals for my Ryzen 9 3900X and Radeon RX 5700 XT while I slaughter the minions of the Dark Lord!

Trivia: Krell is a reference to an extraterrestrial race in the science fiction movie Forbidden Planet. See The Short GKrellM FAQ
