On my Nagios monitoring local macine (where my hosts are being monitored) clicking on a Home Dashboard
gives me a nice Server Statistics Summary as follows:

15-min 0.28

User 12.90%
Nice 0.00%
System 1.00%

How can I get the same summary server statistic (mimic) for my monitoring remote hosts?

The Server Statistics for localhost is a special dashlet because it has direct access to the localhost. This particular dashlet is custom made just for localhost. You can take performance graphs from any host and place them on the dashboard...

Question #1 .
Can you suggest what specific packages do I need to install on my remote monitoring hosts in order to get CPU (like I/O Wait, Steal, Idle) and Memory Stats (like Used, Free, Cached)?
Question #2.
If we buy Nagios XI subscription for our company, do we get more available packages for Server Stats?
The currently available monitoring packages are very limited to what you can really monitor. For instance we would like to be able to monitor OS Performance, Memory Paging, Processor Performance, etc.
What do we gain if decide to buy Nagios subscription besides that we could have more than 6 remote hosts?

P.S. We are using RedHat Linux OS v5.7 via ssh connection.

We have wizards on the Nagios Exchange that will configure almost any kind of device for those metrics

Also, there are almost 2500 plugins on the exchange that can monitor just about everything conceivable.
