Power HMC — Per System

Single managed-system deep-dive for IBM Power servers, driven by the power-hmc-exporter — an agentless Prometheus exporter that polls the HMC REST API and PCM. Pick one managed system and see its capacity, every LPAR, both VIOS, and the full I/O path — CPU, memory, network (SEA), Fibre Channel (NPIV) and Virtual SCSI — on a single screen.

It is the drill-down companion to Power HMC — Overview (estate-wide) and Power HMC — Per LPAR (single partition): every name in the LPAR table links straight through to the per-LPAR dashboard.

Requirements

• power-hmc-exporter v0.9.0+ scraped by Prometheus (the power_hmc_* metrics) — grab the free-trial binary →
• A Prometheus data source — selected at the top via the Datasource variable.
• Optional: aix-exporter on your VIOS for the Fibre Channel link/resource error panels (aix_fcstat_*). Where absent, those panels show No data.

What you get

• Identity & capacity — type-model, serial, processor mode, firmware, state, cores & RAM allocated vs total, and a PCM Sample Age stat (HMC V10 PCM is ~6–7 min latent; thresholds flag staleness at 10 / 15 min).
• LPAR inventory — every partition (ID, type, OS, state, CPU, RAM), each name linking to the per-LPAR dashboard.
• Compute — CPU pool %, memory %, Top 15 LPARs by CPU and by RAM.
• Per-VIOS — CPU utilised vs virtual-processor cap, memory used vs assigned.
• Network (SEA) — throughput per SEA, usage by LPAR with the serving VIOS in the legend (self-correcting on failover), and a drops panel (should stay ~0).
• Fibre Channel (NPIV) — per-LPAR NPIV per physical FC port with WWPN cross-reference, Top 15 consumers, and optional per-VIOS FC error panels.
• Virtual SCSI — per-vhost throughput per VIOS and total VSCSI per LPAR.

Variables

Datasource, Managed System, VIOS, LPAR State, FC Device, SEA Device. Repeating rows fan out per VIOS / SEA / FC port.

Notes

• Throughput uses read_bytes + write_bytes (HMC reports NPIV transmittedBytes as 0).
• Powered-off systems return no PCM sample — surfaced via Sample Age, not as an error.
