Nagios Support Forum

Hi,

We have few requirement to monitor in nagios,

1) Multiple CPU loads (If a server has multiple CPUs – As is the case will all servers in estate) we need the load to be monitored for each CPU
individually to get correct picture.
2) Along with disk utilization, also monitor disk performance (eg response times) on servers.

Please help me to achieve the monitoring.

The NCPA client can monitor disks individually for read/write_time, read/write_bytes, and read/write_count.

NCPA's built in CPU monitoring will monitor aggregate information across all CPUs. But you can monitor Windows Performance Counters via NCPA. This would allow you to get information on a specific CPU. Here is an example of a VM with 2 cores.
The first number defines the NUMA node, the second defines the core number in that NUMA node.
