2. What are components of prometheus?
   -The Prometheus Server:It collects metrics in the form of time series data from nodes and stores them.
   The process of collecting metrics is referred to as scraping.
   -Client Libraries and Exporters: Prometheus stores data in a time series format, and only accepts data of that form.
   -Push Gateway:The Prometheus Push Gateway exists solely to allow short lived jobs to expose their metrics to Prometheus.
   -Alertmanager:The Prometheus Alertmanager allows you to define your own alerts on the collected metrics.
   How Prometheus works?

Prometheus scrapes metrics from instrumented jobs, either directly or via an intermediary push gateway for short-lived jobs. It stores all scraped samples locally and runs rules over this data to either aggregate and record new time series from existing data or generate alerts.
