Metricbeat is a lightweight shipper that periodically collects metrics from the operating system and from services running on the server. It helps one to monitor servers by collecting metrics from the system and services such as Apache, MongoDB, Redis, and so on, running on the server. Metricbeat can push the 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 to have it installed on the edge servers where the services are running.
