However, the easiest way is not necessary the most scalable and convenient. The easiest way is to pre-generate the configuration file and upload them to the network element using ZTP process. The next step would be the solution, which automatically deploys the proper configuration on the network element, when it’s deployed.
#DOCKER SYSLOG NAME FULL#
In the same article about ZTP, we have pointed out that the initial zero-touch provision process is the just the first step in the full automated network. When I was developing the ZTP (zero-touch provisioning) stack the last time, I used logs from the Docker containers a lot for troubleshooting of the ZTP process. Obviously, the applicability of the logs are much wider than a network functions. Least out of band management connectivity.
Their details in general, because the syslog is configured, when you have at Network function, long before you configure interfaces.
It’s quite often the first thing you configure on the Impossible to imagine any operational activity, especially troubleshooting, As the monitoring and automation is integrated in both projects now, I’ve decided to name the article “DC/SP” showing the real applicability as well as the job done by integration. Then I’ve tried to perform that for the Data Centre Fabric and that partially flied, though the same restrictions have been applicable as with the Service Provider Fabric. I’ve initially tried to deploy the log collection via syslog for the Service Provider Fabric, but it doesn’t work due to network elements SW (more details on this topic come later). Well, true, but there is a reason for that. The name of the article could be misleading. Or otherwise, for commercial purposes without the Means, electronic, mechanical or photocopying, recording, Retrieval system, or transmitted in any form or by any So, we need to disable (comment) system() source in configuration file: sed -i 's/system()/# system()/g' /etc/syslog-ng/nfĢ.No part of this blogpost could be reproduced, stored in a This source reads platform-specific sources automatically, and reads /dev/kmsg on Linux if the kernel is version 3.5 or newer. The system() source is in default configuration. Error opening file for reading filename='/proc/kmsg', error='Operation not permitted (1)' Since syslog-ng doesn't have direct access on the kernel messages, you need to disable (comment) that in its configuration: sed -i 's|file ("/proc/kmsg"|#file ("/proc/kmsg"|g' /etc/syslog-ng/nfġ.

You can fix above error by installing syslog-ng-libdbi package: yum install -y syslog-ng-libdbiĢ. Plugin module not found in 'module-path' module-path='/lib64/syslog-ng', module='afsql'

So, I try to install syslog-ng inside the docker container. I've tried to run docker as -log-dirver as syslog or journald, both works strange, the /var/log/local0.log show console output of docker container instead of my application's syslog when I try to run this command inside container logger -p -t a message When I move my application into docker, I found it is difficult to show the syslog. My application will send out syslog local0 messages.
