Filebeat not sending all the logs to the output file

Elastic Stack Beats

There are a couple of files in /opt/logs/*.0 and the file beat reads them properly but does not print all the lines and sends them to the output file . Is there a problem with my matching ? How can I make sure everything from 2 files stdout.0 and stderr.0 from /opt/logs/ is read and sent to the /apps/logs/abcd/web_xxx.log ?
