IBM Power Systems Performance Monitoring

AIX monitoring example

Tool gets data either from the HMC CLI (via SSH) or via HMC REST API.

Monitoring resources

  • CPU pool
  • Shared Processor Pools
  • LPAR
  • Physical interfaces
  • HMC

Monitoring metrics

  • CPU performance (CPU cores)
  • Memory allocation
  • Eth/FCS/SR-IOV/SAS/IVE adapter performance (MB/sec, IO per sec, Latency)

Other features

Further OS detailed data can be obtained from AIX/Linux and IBM i OS agents running on LPARs.
AIX/Linux/VIOS OS agent metrics:

OS CPU CPU sys, user, IO wait
CPU queue Load avrg, Blocked processes
JOB CPU, Memory
Memory utilization Used, FS cache, Pinned
LAN (ethernet adapters) MB/sec, packet count
SAN (FC,vSCSI adapters) MB/sec, IO/sec, Latency
Paging space utilization Usage in %
Paging rate MB/sec
Filesystem usage Usage in %, GB
Active Memory Expansion (AME) MB
Shared Ethernet Adapted (SEA) MB/sec, packet count
WLM CPU, Memory, DKIO
WPAR All OS agents metrics
