In respect to this, what is the use of Filebeat in Elk?

Filebeat, as the name implies, ships log files. In an ELK-based logging pipeline, Filebeat plays the role of the logging agent — installed on the machine generating the log files, tailing them, and forwarding the data to either Logstash for more advanced processing or directly into Elasticsearch for indexing.

One may also ask, what is Logstash in Elk? Logstash is a server-side data processing pipeline that ingests data from multiple sources simultaneously, transforms it, and then sends it to a "stash" like Elasticsearch. Kibana lets users visualize data with charts and graphs in Elasticsearch. The Elastic Stack is the next evolution of the ELK Stack.

Just so, what is beats in Elk?

Beats are essentially lightweight, purpose-built agents that acquire data and then feed it to Elasticsearch. The magic of Beats is the libbeat framework that makes it easy to create customized beats for any type of data you'd like to send to Elasticsearch.

How can I tell if Filebeat is working?

How to verify filebeat parsed log data count

  1. Look in the registry file (location depends on the way you installed, it's /var/lib/filebeat/registry on DEB/RPM) and check how far filebeat got into the files.
  2. Increase logging verbosity in filebeat to info level and check if it writes data.
  3. Increase verbosity of Logstash to check that data reaches LS.
