Is there any way to monitor multiple VPS resources in terminal?

einverne

I know there are a lot of methods to monitor VPS CPU, memory, etc on the website, such as Cockpit, Netdata. I just wonder is there any method to monitor VPS in terminal.

The only way I know is to SSH into a single VPS and run htop.

Glances?

You can use script from here:
https://github.com/atarallo/TECMINT_MONITOR/
There are many others.
You can also build your own script using common Linux commands.

For Simple Monitoring Resources ( CPU | RAM | Bandwidth ) of VPS you can use split screen available in terminal multiplexer programs.

Here are reference readings:

Why not just split your terminal into multiple windows? I use Terminator so I usually have it split between 2-8 panes depending on what I'm doing. Everything is visible at once, from however many servers you want.

No special scripts required.

Glances has a web interface that seems to be what you are looking for.

You can use tmux to split your shell terminal and have it be persistent. On your monitoring server, run the command tmux. Split the screen using ctrl+b, " and ctrl+b, %. Resize with ctrl+b, {up,down,left,right} arrows a few times and move to different ones by using ctrl+b, {up,down,left,right} arrows once. SSH into the servers you want to monitor and run htop on each panel. Once you're done, you can do ctrl+b, d to detech the session which will bring you back to your normal shell. You can re-attach by running the command tmux a. Tmux is a very useful tool and it can do other stuff, I recommend it in your workflow.

If you use Netdata, you can connect all the servers to Netdata Cloud (which is free) and see them all through one web UI. It can show both separate charts and combined charts (e.g. average CPU usage across all servers).

Here, I can offer some options. The default language for some scenarios may not be friendly enough to you, but it is usable.

1. If you use ios or mac os, you can download and install an app called servercat which has a cool demo page that shows resource briefings for all servers. Essentially this is an enhanced ssh terminal where everything is implemented natively.
2. ServerStatus is a server probe and display page, you can go to github to search for it.
3. Naiba/nezha is another server probe program available on github. It's more modern, more comprehensive, has a nice visual interface, and can be installed with one-click script or docker. The only difficulty for you is that this is software developed by the Chinese.

The tip about using tmux splits to show multiple ssh'd htop sessions is a good one. To optimise screen layout for high-core count machines, you can switch from showing all CPU bars to a single average CPU bar.
