After successfully accessing Netdata, the interface of Netdata will be displayed as below:

I will explain the Netdata interface:

• 1: Your VPS/server hostname name.
• 2: The main system parameter table on your VPS/server:
  • 2.1: Current CPU usage. From 0.0 to 100.0 is the maximum.
  • 2.2: Current RAM usage. Unit
  • 2.3: Current outgoing network traffic.
  • 2.4: Current inbound network traffic.
  • 2.5: Data write speed to current storage hardware.
  • 2.6: Data read speed to current storage hardware.
  • 2.7: Amount of virtual RAM (SWAP) currently in use.
• 3: Go into the details of the parameters.
• 4: Detailed parameters.

You can use your mouse or hand (on touch screens like iPad, smartphone…) to pull back many previous timelines, this will make it extremely convenient to track the history of system resources.

If you pay attention, you will see a bell 🔔 in the upper right corner. If something is wrong with your system, this bell 🔔 will have a tick next to it and you should click to see the warning. As below, there is a warning at (1).

After clicking on the alert, you will get a small window listing all the current alerts. Here, I only have one warning about dropped packets. You can click the locator icon in (2) to quickly move to the chart receiving the current alert, as shown below:
