What are the names of the events in Logstash?

Logstash offers an Event API to developers to manipulate events. In this tutorial, this event is referred with various names like Logging Data Event, Log Event, Log Data, Input Log Data, Output Log Data, etc.

For scenarios where extensive log manipulation isn’t needed there’s an alternative to Logstash known as Beats. Beats is a family of tools that can gather a wide variety of data from logs to network data and uptime information. Many applications will use both Logstash and Beats.

If you configure Logstash to run multiple filter threads, there is a good chance that the Multi-Line filter will break and may cause Logstash to crash. When sending multiple logs with TCP, generally speaking, TCP will break them up log by log, sending one after the other in separate packets in a stream.

max_open_files: It specifies the maximum number of input files by Logstash at any time. path: Specify the path of the files and it can contain the patterns for filename. start_position “end” You can change to “beginning”, if you want that; initially Logstash should start reading the files from the starting and not only the new log event.

Logstash can also be used for handling sensors data in internet of things. Logstash is open source and available under the Apache license version 2.0. It is the main object in Logstash, which encapsulates the data flow in the Logstash pipeline. Logstash uses this object to store the input data and add extra fields created during the filter stage.

If you were to map the clientip field as type ip, and a log line with a host name were to be pushed to Elasticsearch it would result in an error, and that document would not be indexed due to a mapping conflict. The location field is also a special mapping type. It is an array of longitude and latitude, indicating a single point on a map.
