Stack not working with SIDECAR_SYSLOGNG #472
Comments
|
As a aditional data, I exec my librenms docker when it is inaccesible on port 8000 and saw that the port isn't listening: librenms:/opt/librenms# netstat -tulnp I tried the same after disabling syslogng side car and I got this: librenms:/opt/librenms# netstat -tulnp |
|
Update 2: I try the validation command and got the following: with syslog-ng side car disabled:
[OK] Installed from the official Docker image; no Composer required with syslog-ng sidecar enable

Howdy. I just ran into this issue myself. There's a lot of deprecated documentation out there, including on the LibreNMS GitHub page itself. So first off, you do not need to set "SIDECAR_SYSLOGNG=1" in the env file. You can find that parameter already in your docker-compose.yaml file. Secondly, regarding ("Create syslog.yaml file with "enable_syslog: true"), this is also unfortunately deprecated or simply incorrect. There's another incorrect example on the docker notes page for syslog-ng here. You need to add $config['enable_syslog'] = 1; to config.php, but that file is within the container and not persistent, however you are passing your local directory /librenms into the container directory /data according to your docker-compose.yaml file. If you create a file in your base OS ./librenms/config/config.php, those values will be included and/or overwrite values within the default /data/config.php file within the container. Put this within ./librenms/config/config.php and restart the container. Make sure you also setup the syslog host in your network devices and endpoints so that they know to forward traffic to the LibreNMS server. |
Support guidelines
I've found a bug and checked that ...
Description
By default my fresh install works out of the box after cloning this repository and following the guide to start librenms.
Then I tried to use syslog-ng side car, in order to do this I did:
After this I restart the docker stack and everything boots:
But my librenms GUI become unreachable. The logs from failing stack below:
Expected behaviour
As far I understand this variable should enable syslognd side car and the librenms gui should be accesible.
Actual behaviour
When I put "SIDECAR_SYSLOGNG=1" on librenms.env file and restart the stack the librenms is not working.
As soon I configure "SIDECAR_SYSLOGNG=0" or even delete this variable from librenms.env and restart the stack the librenms GUI becomes reachable again.
Steps to reproduce
first:
Try to access http://localhost:8000, it should work
If this works, then try:
Try again access http://localhost:8000, this time it shouldn't work
