Logstash not load conf.d directory

[mcoa (miguel)]

Hello,
I'm use Logstash v7.3.2-1 on Centos 7. When started the service from systemctl run fine but not load the /etc/logstash/conf.d/ directory . My filter work fine with the "manual" command:

1. /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/apache.conf

ie:

{
    "archivename" => "Audiencias/xxxx-0-1230",
         "action" => "MKCOL",
       "clientip" => "10.94.10.41",
           "host" => "oc-web-01.example.com",
       "username" => "JG1230-02",
        "message" => "10.94.10.41 - - [16/Sep/2019:18:36:17 -0300] \"MKCOL /remote.php/dav/files/JG1230-02/Audiencias/xxxx-0-1230 HTTP/1.1\" 201 - \"-\" \"Mozilla/5.0 (Windows) mirall/2.3.3 (build 1) (Nextcloud)\"",
       "@version" => "1",
     "@timestamp" => 2019-09-16T21:36:17.000Z,
       "response" => "201",
           "path" => "/var/log/httpd/access_log"

I edit the /etc/systemd/system/logstash.service and add "-f" "/etc/logstash/conf.d/apache.conf" but not load file .
