logstash:tldr:43e52
This command is instructing the computer to run the Logstash tool with elevated privileges using the "sudo" command. Logstash is an open-source data processing pipeline that allows you to collect, process, and forward logs and other event data.
The "--config" flag indicates that you want to specify a configuration file for Logstash, and the "${logstash_config-conf}" is a placeholder for the actual filename or path of the Logstash configuration file.
By running this command, Logstash will be invoked with the specified configuration file to process and manipulate the logs or event data based on the defined rules and filters in the configuration. The use of "sudo" allows the command to be executed with administrative privileges, which may be required depending on the system settings and permissions.
