rt-analyzer
Linux real-time configuration analyzer with scoring and fixes
rt-analyzer reads /proc and /sys and applies 61 expert rules across 7 categories to produce a weighted 0–100 score for Linux real-time (PREEMPT_RT) systems, with prioritized, copy-pasteable remediation.
It catches the failures that look fine but aren't: isolcpus set without nohz_full, C-state exit latency that silently bounds worst-case wakeup time, and effective_affinity quietly overriding the smp_affinity you requested.
