"realtime" server load monitoring

How can i monitor the server load in "realtime"
and also is this a recommended practice or will it burden my server or its performance?

Please recommend the best 5 realtime server monitoring apps or websites
that monitors load in realtime.

I am not talking about web analytics, but instead i am looking for realtime server analytics

 

You can use Nagios or Munin.

 

Nagios is the best.

 

You can simply use the command "w" in ssh to monitor the load in real time. A command like the following would update the screen automatically:

 

You can see the monitoring history in monitoring tools later and compare trends.

 

What monitoring tools? and where?

 

I have Cpanel and can see the status but want something in realtime so i don't have to be refreshing. I want something that will be updating every 30 seconds.
Will watch w be able to do that?

 

i also want it.

 

Check Nagios but it needs to be setup.

 

By default, it would update every 3 seconds. You can change this value with -n flag. To set this every 30 seconds, use this:

watch -n 30 w
