[observability] zabbix 3934 nvps · profiled rcache utilization (0.4% actual vs. overconfig)
→ cpu 36→12 cores (-67%) load 175→32 (-82%) nvps flat zero restart
[data-integrity] clickhouse 4-shard cluster misconfigured as 2S×2R + internal_replication
→ 36-59% silent read loss per query · fixed via hot-reload · 19 TB reclaimed
[memory] glibc per-thread arena fragmentation under ~2k msg/s json churn
→ mimalloc 2000 MiB/pod → 250 MiB/pod (-87%) no leak no restart
[ha-platform] 10k-agent websocket mgmt: single instance → redis-backed multi-replica
(presence · pub-sub routing · sigterm drain)
→ rolling restart agent downtime <1s vs full-restart = 2200 agents drop
[incident-492] 7600 overseas agents offline · machines alive · no app error
root: oversea dns line → broken cloudflare cname → 403 on /ws/agent
fix: dig +subnet confirmed · direct A record · 4 min full recovery
[aiops] hermes-agent (NousResearch) deployed in production ops
extended with custom MCP server: 154 infra skills (vsphere · ansible · metrics)
3-tier model fallback · full sqlite audit log per agent action · zero inbound ports

ai-native workflow:
heavy use of ai agents for coding · root-cause analysis · operational automation
my half: problem discovery · architecture decisions · production validation · red lines
prefer boring reliability over clever fragility
prefer static binaries over dependency piles
prefer observable failures over silent magic
prefer terminal workflows over dashboards
