### Are you running node_exporter in Docker?
No.

### What did you do that produced an error?
Nothing.

### What did you expect to see?
Process per CPU, MEMORY as consumption.
Network Interface status UP/DOWN,speed link.
Threads.

### What did you see instead?
n/a.

Process per CPU, MEMORY as consumption.

I'm not sure what this means.

Network Interface status UP/DOWN,speed link.

This is already covered by #794.

Threads.

Can you be more specific? Are you sure this is not covered by #950?

Process per CPU, MEMORY as consumption.

I'm not sure what this means.
This means: Running Processes by Memory and CPU Usage in Linux
# ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head

Network Interface status UP/DOWN,speed link.

This is already covered by #794.
This is only applied to "bonding" or general for network?

Threads.

Can you be more specific? Are you sure this is not covered by #950?
I think is covered, will be in the next release of node_exporter 0.17?

Thank you.

[SuperQ]

Per-process metrics are out of scope for the node exporter. I would look into cAdvisor or the process_exporter.

Even better would be to add a client library in your applications. This way you can directly measure each process. The Prometheus client libraries include a number of automatic metrics for process memory and CPU information.

#794 is about more information from /sys/class/net/*, I've updated the title to make that more clear.

Thank you @SuperQ this sounds great.
Have a great day.
