Hello,
I am fairly new to all this, I have configured Nagios as per the quick setup and all is working well. I have it montioring CISCO swtiches!!!
My question is that can you monitor HP Proliant Servers running W2k3 without having to instal an agent like NSClient++ .
The servers already has the HP System Management installed. There is a page for “HP Management Agents Configuration”
A brief answer will do.
Thanks
