K dispozici je nový CLI nástroj witr sloužící k analýze běžících procesů. Název je zkratkou slov why-is-this-running, 'proč tohle běží'. Klade si za cíl v 'jediném, lidsky čitelném, výstupu vysvětlit odkud daný spuštěný proces pochází, jak byl spuštěn a jaký řetězec systémů je zodpovědný za to, že tento proces právě teď běží'. Witr je napsán v jazyce Go.
