What the Ledger says
Zabbix is extending a fully open-source monitoring core toward tracing, event processing and AI agent access in 8.0, with flow and topology to follow in 2027. Its record is the most transparent here: a public roadmap, regular LTS releases, strong scale and HA, and few slips. The gap a buyer must fill is network depth, since flow analysis, configuration backup and automatic topology still need other tools.
AI say-do: 2 announced, 2 GA (GPU plugins, LLM webhooks), 0 preview, 0 pending, 0 dropped; the official MCP server is in 8.0 RC1. The AI is statistical trigger functions plus LLM summaries by webhook.
