HMC (Hardware Management Console)

A Hardware Management Console (HMC) is an appliance used to configure and control one or more IBM Power servers, called managed systems. It creates and manages logical partitions, activates Capacity Upgrade on Demand and relays system information to IBM support. If the HMC fails, the server keeps running, but its partitions cannot be reconfigured.

How XorMon monitors it

✓XorMon reads IBM Power performance data from the HMC REST API with a read-only user, for AIX, IBM i, VIOS and Linux on Power LPARs.
✓The data is sampled every minute and collected every 20 minutes, and HMC performance data collection (LongTermMonitor) must be turned on.
✓The REST API is supported on HMC v8 and later over TCP port 443; older HMCs might require port 12443.
✓With a dual HMC setup, one HMC is configured as the primary and used preferably for data collection, and the other acts as a backup in case the primary becomes unavailable. The same credentials must be used on both.
