I'm newbie to nagios, but have found that it has tremendous benefits for System/service admin. I'm starting a new project to implement a new monitoring system to monitor all my team's servers (which include monitoring both application and hardware faults). Anyway, the limitation are that most of the servers have off-the-shelf software installed and I cannot install any clients (NRPE, or other agents) on them or it will break the agreement we have with vendors.
Therefore, I have questions as followed:
1. Those servers have SNMP enabled, is there a way to utilize this without installing anything?
2. If I need standard monitoring (disk, cpu, memory, load), do I need to install anything on clients. I see that when installing nagios servers, we install these plugins already, so can it be used without installing NRPE on client side?
Thank you very much in advance
