02. Monitoring Using Prometheus

Prometheus

In Greek mythology, Prometheus (/prəˈmiːθiːəs/; Greek: Προμηθεύς, pronounced [promɛːtʰéu̯s], possibly meaning "forethought")[1] is a Titan, culture hero, and trickster figure who is credited with the creation of man from clay, and who defies the gods by stealing fire and giving it to humanity - https://en.wikipedia.org/wiki/Prometheus

In the world of Cloud DevOps, Prometheus is a very useful, flexible tool for our monitoring.
