How to Install Splunk on Your Synology NAS

Splunk is a software platform to search, analyze and visualize the machine-generated data gathered from the websites, applications, sensors, devices etc. which make up your IT infrastructure and business. If you have a machine which is generating data continuously and you want to analyze the machine state in real time, then how will you do it? Can you do it with the help of Splunk? Yes! You can. You see servers and devices, apps and logs, traffic and clouds. Splunk sees data. Everywhere. Splunk provides the leading platform for Operational Intelligence. It allows the curious to see closely what others ignore, machine data, and find what others never see: information that can make your company more productive, profitable, competitive and safe. What can you do with Splunk? You only need to ask. In this step by step guide I will teach you how to install Splunk on your Synology NAS device using Docker.

Note: This guide works perfectly with the latest Splunk 8.2.5 release.

STEP 2

Install Docker via Synology “Package Center”.

STEP 3

Go to Control Panel / Task Scheduler / Create / Scheduled Task / User-defined script. Follow the instructions in the images below.

STEP 4

Once you click on User-defined script a new window will open. Follow the instructions below:

General: In the Task field type in Install Splunk. Uncheck the “Enabled” option. Select root User.
Schedule: Select Run on the following date then select “Do not repeat“.
Task Settings: Check “Send run details by email“, add your email then copy paste the code below in the Run command area. After that click OK.

docker run -d --name=splunk \
-p 8321:8000 \
-e SPLUNK_START_ARGS=--accept-license \
-e SPLUNK_PASSWORD=yourpassword \
--restart always \
splunk/splunk

Note: Before you paste the code above in the Run command area, change the value for SPLUNK_PASSWORD and add your own password.
Note: Make sure you set up your password correctly from the start (at least 8 characters). If your password does not meet complexity requirements, the splunk container will go into an eternal loop and will not be deployed correctly. Reported by De Cabecera.

STEP 5

After you click OK on STEP 4 a new warning pop up window will open. Click OK.

STEP 6

After you click OK on STEP 5, select your “Install Splunk” Task then click the “Run” tab. You will be asked to run Install Splunk – click Yes. Follow the instructions in the image below.

STEP 7

Go back to STEP 1 or you will deal with karma 🙂

STEP 8

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. The current container is about 2GB so, depending on your connection, it could take some time. Just wait until the installation is complete before proceeding to the next step. Now open your browser and type in http://Synology-ip-address:8321 Follow the instructions in the images below. The default username is admin and the password is the one you have chosen at STEP 4.
