Router level Site-to-Site VPN users, most of the case the routes are automatically added for you by your Router. This usually boils down to device firewall that is blocking UDP port 161 Check Firewalls on Synology and Device(s)Ĭheck your Synology & device firewalls, static routes, router settings etc to allow UDP port 161 SNMP protocol, especially true for remote polling of devices VPNs If your NAS is able to communicate with the devices, there are usually no problems with your docker commands as the docker network interface is bridged to your NAS. Stop, Remove, Delete Containers Networking issues & a quick 101įrom your Syno terminal, ensure your Syno NAS can communicate with other devices (eg: ping). If in doubt, go back to DSM > File Station and delete folders/files the GUI way If you decide to remove any of the MariaDB or LibreNMS containers, remember to also remove the existing data from the persistent data folder eg: /volume1/docker/mariadb, /volume1/docker/librenmsīe careful when running rm -r with root privileges, ensure you are deleting correct folders.Įg: rm -r /volume1/ will delete your whole volume1 folder!!! Always make sure you are in the correct folder while running commands. List all containers / Or view them in your DSM Docker appĬheck your current Docker gateway (your NAS IP when access from inside Docker) If you come across any errors, it does not hurt to remove the Docker container, check the docker run command and run it again as it can be confusing with many docker variables I have run the above commands multiple times previously when I was still testing LibreNMS and configuration, so this should work as intended on a Synology NAS Settings (Gear icon beside Search bar) > Global Settings > Webui Settings > Graph settings > graph type LibreNMS can output SVG graphs which has better clarity than png While not everyone has access to two or more physical locations, your only choice would be to set up a hosted server Eg: DigitalOcean Use SVG graphs The stable LibreNMS is used to monitor the Router of the unstable location and sends alerts when necessary One of the locations suffers from electrical power blackouts and unstable Internet connection, while the other location is located in a city with 24hrs electricity and no Internet downtime My scenario with LibreNMS is that I have two LibreNMS instances installed at two different physical locations If your LibreNMS server or Network goes down, how will it be able to send an alert to you? Please do keep this in mind, if you are planning to monitor devices that often have downtime, it will make sense to have the LibreNMS installed on a location that is 24hours online with a stable Internet connection. $config = "/tmp" // Syno-NASĪfter you have edited the to your liking, remember to perform a restart on your docker container to reflect the new settings docker restart librenmsĪlerts can be useful as they will notify you when something goes down and sends you a recovery message with elapsed downtime $config = // Syno-NAS ignore docker mounts $config = '/^docker+$/' // ignore docker interfaces
$config = '/^lo.*/' // ignore loopback interface $config = 0 # Enable Cisco SLA collection and display $config = 0 # Enable BGP session collection and display $config = 1 # Show Errored ports in summary boxes on the dashboard $config = 0 # Enable Customer Port Parsing $config = 1 # Enable Locations dropdown on menu Paste in the following example, which is heavily customised for Synology devices, change accordingly to LibreNMS’s documentation

Google on how to use “vi” as Synology does not have “nano” Back to the Terminal, we can set up custom settings to LibreNMS to exclude features like Billing and Services etc since we are not using them cd /volume1/docker/librenms vi
