What the Ledger says
Opsview is a Nagios-derived monitor that ITRS rebuilt in 2019 as Go and Python microservices on InfluxDB, and it is now adding hypervisor breadth (Nutanix AHV 2021, Proxmox 2024) and AI hooks (anomaly baselines 2025, an MCP server 2026). The record shows one or two solid releases a year and promises that mostly shipped on time, with business-service views and multi-tenancy as long-standing strengths. The trade-off is a proprietary Opspack format, subscription-only buying from a private-equity owner, and evidence that rests largely on the vendor's own knowledge base.
AI say-do: 2 announced, 2 GA (anomaly baselines on time; GPU Opspack 18 months late), 0 preview, 0 pending, 0 dropped. The AI is statistical anomaly baselining plus an MCP server; there is no LLM assistant in the product.
