Pessimal
A disk-space monitoring stack for headless VMs: a minimal OpenTelemetry agent sends VM metrics to an OTel collector (Signoz for now), and an iOS/macOS app queries the metrics at regular intervals. It works with an existing Signoz instance at no extra cost, Honeycomb and Clickstack compatibility is untested so far, and the apps are currently in private TestFlight.
What it addresses
Headless VMs can silently run out of disk space, which repeatedly bit the author.

“https://github.com/lightless-labs/pessimal: I got bitten a few times too many by my headless VM running out of disk space, so I had Claude build a minimal OTel agent sending metrics to an OTel collector (Signoz for now), and an iOS / macOS app to query it at regular intervals. Works nicely with my existing Signoz, costs nothing extra, but I’ve yet to test it against Honeycomb and Clickstack. Apps are in private TestFlight for now.”
