Hi, any news on that? Please reach me if you have any comment
This looks like a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1949673 which is fixed, verified, and set to be released imminently as part of 16.2.2 Here is the patch which suggests the fix: https://review.opendev.org/c/openstack/tripleo-heat-templates/+/785956/4/deployment/metrics/qdr-container-puppet.yaml I don't have an environment in front of me to check the rendering, but my reading of this is that you need to double-up the backslashes in the rsyslog config file (accomplished by the change of quotes in the patch). You also need to fix the path to the log file. If this successfully works around the rsyslog startup problem, then we can be pretty sure that the 16.2.2 update will fix it more permanently.
Based on Chris' comment, this should be fixed by z2, which is supposed to be sent out on March 23rd. If this is not resolved in the next release, please reopen and we'll investigate.
