How to Install LibreNMS on Your Synology NAS

LibreNMS is an auto-discovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems including Cisco, Linux, FreeBSD, Juniper, Brocade, Foundry, HP and many more. In this step by step guide I will show you how to install LibreNMS on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest LibreNMS v25.4.0 release.

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

  • STEP 18

Please wait approximately 10 minutes or you will get a blank synology error page if you try to connect too soon. Now open your browser and type in your HTTPS/SSL certificate like this https://librenms.yourname.synology.me that you have previously created at STEP 6. In my case it’s https://librenms.mariushosting.synology.me If everything goes right, you will see the LibreNMS installation page. Type in your own Admin User details, then click Add User. Follow the instructions in the image below.
