Metricbeat is a lightweight shipper that periodically collects metrics from the operating system and from services running on the server. It helps you monitor servers by collecting metrics from the system and services such as Apache, MongoDB, Redis, and so on, that are running on the server. Metricbeat can push collected metrics directly into Elasticsearch or send them to Logstash, Redis, or Kafka. To monitor services, Metricbeat can be installed on the edge server where services are running, but it also provides the ability to collect metrics from remote servers as well. However, it's recommended that you have it installed on the edge servers where the services are running.
