pico_exporter is a system metrics exporter written in C that runs in about 120 kiB of memory. It is a drop-in replacement for the Prometheus node_exporter, but instead of waiting to be scraped it pushes the metrics to an OTLP gateway over TLS, so there is no need for an extra piece of software to pick the metrics up and forward them to the gateway.
