RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
rsyslogd does not send any messages to a remote log concentrator over network after system reboot.
Systemd unit file of rsyslog (/usr/lib/systemd/system/rsyslog.service) is missing the following statement:
<<
[Unit]
...
After=network.target
>>
If rsyslog is configured to send log messages to a log concentrator, after a reboot of the systen, rsyslog is being started before network.target is ready. As sequence, log messages are not being sent out via network.
Adding the dependency to network.target solves the issue.
This dependency was configured in RHEL 7.3 and before in /usr/lib/systemd/system/rsyslog.service
Version-Release number of selected component (if applicable):
- RHEL 7.4
- rsyslog-8.24.0-12.el7.x86_64
How reproducible:
Everytime after system reboot.
Steps to Reproduce:
1. Configure rsyslog to send logs to a network log concentrator
2. #reboot
3. #logger "let me log this"
Actual results:
String "let me log this" does not appear in log concentrator (however, it is logged locally in messages)
Expected results:
String "let me log this" does show up in log concentrator
Additional info:
Diff of rsyslog.service file comparison RHEL 7.3 and 7.4:

"Workaround": Manually restart rsyslog after system boot AND wait for network being up and running. (however, this is no productive workaround).
rsyslog configuration:
# cat /etc/rsyslog.d/syslog.conf
# Send all logs to Graylog/syslog.<fqdn-deleted>
