Interpretation · updated daily by Claude

Automated read of the latest data — bottom line, phase comparison, and notable trends.

Bottom line — Spectre_5 is healthy over the last 24 hours (average response ~590–730ms outside one overnight spike, apdex holding in the high-0.7s during business hours), and the trailing week is steady at 550–670ms with apdex 0.77–0.84. Early Drupal 10 (D10) numbers since Jul 4 continue to look favorable versus the Drupal 8/9 baselines, with the lowest average response time (663ms) and lowest error rate (0.37%) of the three phases.

  • A single overnight spike at 03:06 CDT pushed response time to 2611ms with apdex dropping to 0.39 — an isolated ~1-hour event, not a sustained trend, with normal recovery by 04:06.
  • Daytime traffic (06:00–10:00 CDT) is running 670–730ms, moderately higher than the overnight/early-morning baseline of 445–610ms, consistent with normal peak-hour load.
  • Error rate stayed low all day (0.04%–0.47%), with no sustained elevation outside the 03:06 spike window.
  • The trailing 7 days show a mild upward drift in traffic volume (Jul 25's 34K requests to Jul 28–29's ~150K+), while response time and apdex stayed flat — the app is absorbing more load without degrading.
  • D10 (663ms avg, 0.78 apdex, 0.37% errors) is now tracking slightly better than D9 (699ms, 0.77 apdex, 0.42% errors) and D8 (679ms, 0.79 apdex, 0.39% errors), a positive early signal for the Drupal 10 migration.

Method & caveats

  • Cutovers. Drupal 9 / PHP 8 went live May 23, 2026; Drupal 10 Jul 4, 2026 — marked on every chart that spans them.
  • Drupal 10 is an early read (~5 days). Its phase card uses the Jul 4–9 window directly.
  • Recent spike. Jul 8 shows an isolated response jump (≈2× the prior day), coinciding with elevated reports/progress-API latency that day — an operational blip, not a migration regression.
  • Source & retention. New Relic timeslice metrics (HttpDispatcher, Apdex, Errors/all), ~13-month retention — the full arc back to mid-2025 is covered. Percentiles (p95/p99) live in 8-day event data and are reported in the point-in-time reviews, not here.
  • Refresh. Regenerated daily by a scheduled routine that re-queries New Relic and redeploys to this same URL.
