Hi all,

I have some performance issues to I would like to read the node-red server CPU load in Node-Red and show it somewhere in a Maintenance-Tab.  
I am not a linux person, but I managed to get this line if I simply send a TOP via ssh:

Mem: 720120K used, 309960K free, 1880K shrd, 73440K buff, 303928K cached  
CPU: 33% usr 11% sys 0% nic 52% idle 0% io 1% irq 0% sirq

Now I would like to extract the 33, the 11 and the 0%, sum it up and put it into a msg.payload to use it further.  
Can this be done somehow in Node-Red ?

BR

You could try using `node-red-contrib-cpu` or one of the [other nodes](https://flows.nodered.org/search?term=cpu&type=node)

Are you aware of [@ralphwetzel/node-red-systeminformation](https://flows.nodered.org/node/@ralphwetzel/node-red-systeminformation)?  
This node gives you access to all the data the [`systeminformation.io`](https://systeminformation.io) package collects of your system ... e.g. a lot of stuff around the [CPU](https://systeminformation.io/cpu.html).
