What's installed on your Netdata server?
- Netdata Agent 2, from the official Docker image
- HTTPS and a login password through Caddy, so the dashboard isn't open to everyone
- Read-only access to the server's /proc, /sys and /var/log
- The host's process namespace (pid: host), so server processes are visible
- Anonymous usage reporting to Netdata switched off (DO_NOT_TRACK)
- Firewall with only ports 22, 80 and 443 open, keeping Netdata's port 19999 closed to the outside
What size do you need for Netdata?
Netdata publishes these figures: 100 to 200 MB of RAM on an empty system and 250 to 350 MB on a typical production one, 1 to 5 percent of a single core with default settings and 5 to 20 percent in production, and about 4 GiB of disk by default. If only Netdata runs on the server, 1 GB is enough. If your own apps run there too, add what they need and look at 2 or 4 GB. You can grow RAM, CPU and disk separately from your panel, and your data and IP address stay the same.
| Use | Size | Price | Choose |
|---|---|---|---|
| A few people | 1 GB RAM · 1 vCore · 25 GB NVMe | $2.58/mo | |
| Small team | 2 GB RAM · 1 vCore · 40 GB NVMe | $4.01/mo | |
| Company | 4 GB RAM · 2 vCore · 60 GB NVMe | $6.89/mo |
Who is it for?
- Anyone who wants to see why a server slowed down, on live graphs
- People running their own app on the same server and watching what it uses
- Small teams after per-second metrics with very little setup
- Sysadmins who need to look back at the moment a problem began
What happens after you order?
- Set the size and complete your payment.
- Your server starts and Netdata installs itself. Carry on when the App row in your panel says Netdata is ready.
- On the Overview tab, click Open app. Your browser asks in a pop-up: the login is yonetici, and the password is in the Password row.
- Look through the CPU, memory, disk and process graphs, and change the time range to go back in history.
- If you like, install your apps on the same server and set up alert channels.
With every server
- Daily backups included in the price
- Unlimited traffic
- Full root access
- Scale RAM and CPU up or down later, and grow the disk
- Location: Istanbul · IST-1.
Good to know
- Netdata runs on the container network, so its network interface graphs show the container's network, not the server's total traffic. CPU, memory, disk and process data do come from the server.
- This password belongs to Caddy in front of Netdata, not to Netdata itself. To change it, generate a new hash with caddy hash-password and put it in caddy/Caddyfile.
- The install only monitors the server it runs on. To see other servers, connect to Netdata Cloud or set up streaming yourself.
- Saving chart preferences, custom dashboards and Functions need a Netdata Cloud login. Cloud's free Community plan covers up to 5 nodes, and paid plans aren't included in the price.
- Email alerts aren't set up. On Docker installs, email goes out through msmtp, so you add your own SMTP service to an msmtprc file. That service isn't included in the price.
- The Agent is GPLv3+, and its dashboard is under NCUL1, free to use with the Agent. The container doesn't update itself: run docker compose pull, then docker compose up -d.
Netdata questions and answers
How much RAM does Netdata need?
Netdata's official figures are 100 to 200 MB on an empty system and 250 to 350 MB on a typical production one. 1 GB is enough if only Netdata runs on the server. If you'll add your own apps, allow for what they need too.
How long does Netdata keep its data?
By default, about 3 GiB of disk goes to metrics. Netdata's website describes more than a year of retention on that space, but the real period depends on how many metrics your server produces. You can change the space in the settings.
Do I need a Netdata Cloud account?
No. The local dashboard opens without one, and alerts keep working. A few features, such as saving chart preferences, custom dashboards and Functions, need a free Cloud sign-in and a connected server.
Does Netdata cost anything?
The Netdata Agent is free, with no node limit. The paid part is Netdata Cloud's higher plans, as its free Community plan covers up to 5 nodes. This install runs without being connected to Cloud at all.
Can Netdata monitor more than one server?
This install only monitors the server it runs on. You can install Netdata on your other servers and connect them to Netdata Cloud, or use streaming to collect their data on one parent node. Setting that up is up to you.
Will Netdata slow my server down?
Official figures put it at 1 to 5 percent of a single core by default, and 5 to 20 percent in production. On a small server you may notice that share. If so, add CPU from your panel or collect fewer metrics.
