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.
LibreNMS v24.9.1 release.

STEP 5
Now click the “Create” button. Follow the instructions in the image below.
STEP 6
After you click the Create button, the window below will open. Follow the instructions in the image below.
On the General area, set the Reverse Proxy Name description: type in LibreNMS. After that, add the following instructions:
Source:
Protocol: HTTPS
Hostname: librenms.yourname.synology.me
Port: 443
Check Enable HSTS
Destination:
Protocol: HTTP
Hostname: localhost
Port: 5080
STEP 7
On the Reverse Proxy Rules click the Custom Header tab. Click Create and then, from the drop-down menu, click WebSocket. After you click on WebSocket, two Header Names and two Values will be automatically added. Click Save. Follow the instructions in the image below.

STEP 11
Now create three new folders inside the librenms folder that you have previously created at STEP 10 and name them data, db, redis. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.
STEP 12
Follow my step by step guide on how to activate SMTP for your Gmail account. This step is mandatory. Note: If you don’t want to use the easiest way for SMTP with Google and you already have SMTP details from your own Mail Server, you can just skip this STEP and use your personalized email SMTP details instead.
STEP 13
Log into Portainer using your username and password. On the left sidebar in Portainer, click on Stacks then + Add stack. Follow the instructions in the image below.
STEP 14
In the Name field type in librenms. Follow the instructions in the image below.

If everything goes right, you will see the following message at the top right of your screen: “Success Stack successfully deployed“.
STEP 17
Go back to STEP 1 or you will deal with karma 🙂.
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.
STEP 19
Click the OK icon. Follow the instructions in the image below.
STEP 20
Choose your favorite theme, then click Finish Install. Follow the instructions in the image below.

STEP 23
At the top right of the page, click on the gear icon, then Global Settings. Click on the System tab. In the Specific URL area, type in your own synology.me DDNS with https:// at the beginning that you have previously created at STEP 6. Follow the instructions in the image below.
STEP 24
Your LibreNMS dashboard at a glance!
STEP 25
Monitor your Synology NAS via LibreNMS.
Go to Control Panel / Terminal & SNMP / Click on the SNMP tab.
Select Enable SNMP service.
Select SNMPv3 service.
Type in a Username in the SNMPv3 area. You will need this username later at STEP 28.
Protocol select SHA. You will need this parameter later at STEP 28.
Type in a Password. You will need this password later at STEP 28.
Click Apply. Follow the instructions in the image below.
STEP 26
Go back to STEP 1 or you will deal with karma 🙂.
STEP 27
Adjust your Synology Firewall in Control Panel / Security / Firewall. Allow the SNMP service on port 161.
STEP 28
Open LibreNMS. Click the Devices tab, then +Add Device. Type in the following parameters:
Hostname or IP: 172.17.0.1
SNMP: ON
SNMP Version: v3
Port: 161
Protocol: udp
Auth Level: authNoPrv
Auth User Name: Your own username that you have previously added at STEP 25.
Auth Password: Your own password that you have previously added at STEP 25.
Auth Algorithm: SHA. This is the Protocol that you have previously chosen at STEP 25.
Click Add Device.
STEP 29
The device will be added in a couple of seconds. If you experience any issue when adding your Synology NAS device, this means you forgot STEP 27.
STEP 30
Click Device, then All Devices then Storage. Follow the instructions in the image below.
STEP 31
Click on your NAS name. Follow the instructions in the image below.
STEP 32
Very important STEP. Your graphs and data need a minimum of 15-20 minutes before they are displayed without issues in LibreNMS. If you don’t wait and are in a hurry, you will get several errors in the graphs, like images not being displayed etc. You need to wait almost 15 minutes for the data from your NAS to synchronize in LibreNMS.
STEP 33
Your Magical Graphs at a glance! Click Graphs!
Enjoy LibreNMS!
