Now that the stack is fully configured, you can go ahead and inject some log entries.
```console
# Using BSD netcat (Debian, Ubuntu, MacOS system, ...)
$ cat /path/to/logfile.log | nc -q0 localhost 50000
```
The shipped Logstash configuration allows you to send data over the TCP port 50000. For example, you can use one of the
following commands — depending on your installed version of `nc` (Netcat) — to ingest the content of the log file
`/path/to/logfile.log` in Elasticsearch, via Logstash:
```console
# Using GNU netcat (CentOS, Fedora, MacOS Homebrew, ...)
$ cat /path/to/logfile.log | nc -c localhost 50000
```sh
# Execute `nc -h` to determine your `nc` version
cat /path/to/logfile.log | nc -q0 localhost 50000 # BSD
cat /path/to/logfile.log | nc -c localhost 50000 # GNU
cat /path/to/logfile.log | nc --send-only localhost 50000 # nmap
```
You can also load the sample data provided by your Kibana installation.
