Hi Szilard, There is no filter: source syslog_ng_src { internal(); }; destination d_localfile_syslog_ng { program("/opt/machine/local/bin/write_with_rotation.sh /var/log/syslog-ng-internal.log 10 10" flags(syslog-protocol) suppress(5) disk-buffer( mem-buf-size(2097152) disk-buf-size(4194304) reliable(yes) dir("/tmp") ) ); }; log { source(syslog_ng_src); destination(d_localfile_syslog_ng); flags(flow-control); }; Thanks and Regards, Alex From: syslog-ng <syslog-ng-bounces@lists.balabit.hu> On Behalf Of Szilard Parrag (sparrag) Sent: 19 de maio de 2022 08:59 To: syslog-ng@lists.balabit.hu Subject: Re: [syslog-ng] Local sources seem not to be working CAUTION: This email originated from outside of the organization.

Hi Alex, We've checked it too and syslog-ng does not release the file descriptor of journald even with flow-control enabled. Also, your internal logs seem rather terse, maybe there is a filter which filters out the important parts. Could you please check it? Szilard
