Hi Nagiosers,

I'm just starting my school project in writing plug-ins for Nagios, it's my first time with Nagios and im also learning more about Linux.

In this project i installed Nagios on a Linux box and run several plug-ins.

My question is:

Is there any way that we can know how much memory and cpu percentage do we need

when running 1 plug-in?

I need to make an estimation how much memory and cpu it will take to run

around 300 to 900 plug-ins.

Could you share with me how much memory and cpu does your Nagios plug-in requires when they run?

Thank you,

Adi Yesaya
