1.9.1 System resources that are important for performance monitoring in a logical partitioning feature system
The following are the system resources that are important when you use PFM - RM for Virtual Machine to monitor the performance of a logical partitioning feature system.
-
CPU resource (see 1.9.3)
This is the CPU resource installed on the host machine. It is important for performance monitoring of CPU usage and other items.
-
Memory resource (see 1.9.4)
This is the memory resource installed on the host machine. It is important for performance monitoring of the amount of unused memory.
-
Disk resource (see 1.9.5)
This is the disk resource installed on the HBA (Host Bus Adapter). It is important for performance monitoring of the number of I/O interrupts.
-
Network resource (see 1.9.6)
This is the NIC resource installed on the host machine. It is important for performance monitoring of data send/receive speed and other items.
A system with logical partitioning feature consumes CPU resources when processing access to disks and networks. A failure to reserve CPU resources necessary for processing access reduces performance of the host machine and LPARs. Therefore, the CPU resources are most important when the performance of a system with logical partitioning feature is monitored. When configuring monitoring settings, set the monitoring of CPU resources first.
To set up definitions to monitor these important items, PFM - RM for Virtual Machine provides monitoring templates. Therefore, this section mainly explains monitoring methods that use monitoring templates. It also gives examples of compound report definition, which simplifies monitoring.
