Week -6: SW upgrade applied — Config Drifter migration begins
Why degraded
Reasoning over PM, CM and Inventory signals
CONFIG DRIFT RISK — HIGH
- srPeriodicity parameter: 40ms (golden baseline: 20ms) — scheduling overhead +67%
- prachConfigIndex: 14 (cluster median: 7) — RACH setup latency elevated
- kpi_rrc_setup_success_pct: 96.1% (target >98%) — borderline, declining
- Alarm burden rising: 2 active alarms (avg for archetype: 0.8)
- HW age: 74 months — acceptable, not contributing
- HW/SW EoL: Not flagged
This element shows the classic Config Drifter pattern: SW upgrade 6 weeks ago, progressive CM drift from cluster baseline, NHI declining 4pts/week. Recommend: CM audit and parameter remediation before performance threshold breach.
