HPE Alletra Monitoring in ObserveOps
Overview
The HPE Alletra integration with ObserveOps (formerly known as AIOps) collects configuration inventory and performance telemetry from HPE Alletra all-NVMe and NVMe-ready storage arrays. ObserveOps connects to the array over SSH and collects metrics across six plugin categories: system, node, port, volume, disk and CPG, and host.
These metrics help storage administrators track array capacity, monitor I/O performance at the port, volume, disk, and CPG level, detect cache efficiency changes, and verify host connectivity across the storage fabric.
Prerequisites
- SSH access to the HPE Alletra array management interface is enabled.
- The credentials used for integration have read-only access to the array CLI.
- The HPE Alletra array management IP is reachable from ObserveOps over SSH (port 22 by default).
- The array is added in ObserveOps discovery with the correct hostname, port, and credentials.
