What is a Logstash config file?
To configure Logstash, you create a config file that specifies which plugins you want to use and settings for each plugin. You can reference event fields in a configuration and use conditionals to process events when they meet certain criteria. When you run logstash, you use the -f to specify your config file.

How do I run Logstash config file?
Specify the name of this Logstash instance. If no value is given it will default to the current hostname. Load the Logstash config from a specific file or directory. If a directory is given, all files in that directory will be concatenated in lexicographical order and then parsed as a single config file.
What should be included in a Logstash configuration file?
Each Logstash configuration file contains three sections — input, filter and output. Each section specifies which plugin to use and plugin-specific settings which vary per plugin. You can specify multiple plugins per section, which will be executed in order of appearance. Let’s take a look at this simple example for Apache access logs:
Which is the best filter plugin for Logstash?
The grok filter plugin is one of the most popular plugins used by Logstash users. Its task is simple — to parse logs into beautiful and easy to analyze data constructs. Handling grok, on the other hand, is the opposite of simple.
Do you need experience to work with Logstash?
Working with Logstash definitely requires experience. The examples above were super-basic and only referred to the configuration of the pipeline and not performance tuning. Things can get even more complicated when you’re working with multiple pipelines and more complex configuration files.
How to change the startup script in Logstash?
If you want to change the Logstash startup script (for example, to change the Logstash user or read from a different configuration path), you must re-run the system-install script (as root) to pass in the new settings.
