# Short-Description: monitoring system and time series database.
# Description:       Prometheus is a systems and service monitoring system.
#                    It collects metrics from configured targets at given intervals,
#                    evaluates rule expressions, displays the results,
#                    and can trigger alerts if some condition is observed to be true.
