Logstash version: 5.0.1; when I have many logstash conf files, how can I start these conf files as soon as quickly? not start these conf files like : /path/logstash/bin/logstash -f /path/xxxx.conf Thx so much !!! ---

Put the files in a directory and pass `-f /path/to/directory` to Logstash. Keep in mind that except if you use the multi-pipeline feature in Logstash 6 there is a single event pipeline. If you don't want events from config file 1 to "spill over" into config file 2 you need to use conditionals. ---

It depends. What does normal mean? How would you as a human determine whether things are working okay? ---

I mean that all the input conf , filter conf and output conf files can work normally. for example, i have windows data source input , filter and relevant output conf file, so how can i know these conf files work normally ? when i have so many different data sources , so in the directory have so many conf files. I don't know you can understand me now! thanks ! ---

Oh, okay. Have a look at a tool I wrote, [https://github.com/magnusbaeck/logstash-filter-verifier](https://github.com/magnusbaeck/logstash-filter-verifier). It allows you to write testcases that verify a Logstash configuration. Apart from that you should of course inspect what the outputs receive to make sure it looks reasonable, but I find that the filters are the hard part. Once you get them right the rest is pretty easy and any problems are immediately visible. ---

Dear magnusbaeck, I put the logstash files including one input file , some different filter files and one output file in a directory and pass -f /path/to/directory to start them So i want to know, when to add another filter conf file to the /path/to/directory to process the data source , how can I to restart them ? like : pass -f /path/to/directory to restart them ???? ---

You mean you want to process the original files (read via the file input) again? You'll have to clear the sincedb file and make sure your file input includes `start_position => "beginning"`. See the file input documentation for more on sincedb. ---

the input file like this : input { tcp { port =\> 514 } } because i have a few different types of data to send the same tcp port , so i need to use different filter conf to process , after i add the new filter conf file to the /path/to/directory , how can i load this filter to logstash? only to restart it ? can it influence the old data type ? ---

> only to restart it ? Yes, unless you have automatic configuration reload enabled. > can it influence the old data type ? That depends on exactly what your configuration looks like. ---
