1) Datadog Agent collects events and metrics from hosts and sends them to Datadog where we can analyze the monitoring and performance data

Collector collects host infra data.
DogstatsD collects application metrics on code level.
Both the above collected data will be transferred to forwarder using TCP protocol.
Forwarder send data to DataDog SAAS using http protocol.
For Apache, the metrices will be saved separately which in-turn was fetched by DataDog agent.
From DataDog SAAS, the metrices will be published or fetched in DataDog UI
