logstash: Check validity of a Logstash configuration.
$ logstash --configtest --config ${logstash_config-conf}
try on your machine
This command is used to test the configuration file of Logstash, a data processing pipeline that collects, processes, and forwards logs and other data. Here's a breakdown of the command:
logstash
: It is the executable command to run Logstash.--configtest
: This flag instructs Logstash to perform a configuration test rather than starting the pipeline. It checks the validity and syntax of the configuration file without actually running it.--config ${logstash_config-conf}
: This flag specifies the configuration file to be tested.${logstash_config-conf}
is a placeholder that represents the path or filename of the Logstash configuration file. You need to replace it with the actual path or filename.
In summary, the command tests the configuration file of Logstash without executing the data processing pipeline. It helps to identify any errors or issues in the configuration before running the pipeline for real-time data processing.
