Hi everyone, I host a server with few services running for my family and friends. The server freezes sometimes. Where the services stop responding. If I try to ssh into the server, it takes a lot of time (3 to 5 mins) for it to connect. After being connected, every letter I type takes 2 to 3 mins to appear on screen.
Seems like the server is overloaded with tasks. But I am not sure what load it is running. I have netdata installed. I could pull up following screenshots for insights.
Can someone please help me in troubleshooting the issue?
I have tried testing stress testing my RAM and CPU, and they were fine. But I would start troubleshooting from scratch if you have recommendations for testings softwares.
Please also let me know if there is anything I can pull from netdata to help in trouble shooting.

Difficult to read the graph, but looks like you have less than 4GB ram. Depending what sort of OS and services are running (from above suggestions), this is likely the biggest issue.
You haven’t mentioned which services you’re running, but 4GB might be enough perhaps for a basic OS with NAS file share services. But anything heavier, like running Container services will eat that up. You’d want at least 8GB.
Note also that you may not have a dedicated graphics card? If you have integrated graphics, some ram is taken from System and shared with the GPU. If you’re just running command line, you might eke out a little more RAM for system by reducing the VRAM allocation in your BIOS. See: https://en.m.wikipedia.org/wiki/Shared_graphics_memory
