Installed App for *nix but no CPU/Memory/Disk data

[qubick]

I installed App for *nix which might grab CPU/Memory/Disk usage as I expected.
However, it does nothing, showing no results. Should I set up something on it?

+)
I installed a forwarder to my local machine, and an indexer to the remote-server.
Since my forwarder does not grab anything via the app (*nix), it seems to be forwarding nothing to the receiver…

I appreciate for any help to move forward.

I figured out myself; I need to install add-on apps and enable scripted input - such as cpu.sh, vmstats.sh etc. Once I set up connection via settings > data forwarding and receiving (add hostname:port no.), forwarder automatically forwards data to the designated indexer. Don't forget to check at "leave copy to the local machine" to see data collected from own machine's web interface.
