+### 2026-01-18 [Session 10:00] - Diagnostics Fix Iterations Complete
+- Completed: 2 iterations of diagnostics fixes to improve metric collection
+- **What's Working (Critical Metrics):**
+  - ✅ Connection counts per service (port-based detection working correctly)
+  - ✅ System metrics (load average, memory, CPU breakdown)
+  - ✅ Top processes (CPU and memory consumers identified)
+  - ✅ Connection state breakdown (ESTABLISHED, TIME_WAIT, etc.)
+  - ✅ Basic container visibility (containers appear in top processes)
+- **What's Still Broken (Nice-to-Have):**
+  - ❌ Container stats (cgroup access issues, requires privileged systemd-run)
+  - ❌ File descriptor counts per process (permission issues with /proc)
+  - Note: These metrics are visible through top processes, just not in dedicated sections
+- **Decision: Proceed with Current Metrics**
+  - Critical metrics (connections, CPU, memory) are working reliably
+  - Broken metrics are nice-to-have, not essential for baseline analysis
+  - Container resource usage visible in top processes section
+  - FD counts not critical for current investigation
+  - Continuing baseline collection with working metrics
+- **Baseline Collection Status:**
+  - Running since: 2026-01-17 23:30 UTC
+  - Current duration: ~10.5 hours (of planned 36 hours)
+  - Collection continuing until: 2026-01-19 11:30 UTC
+  - Data quality: Good for critical metrics (connections, system resources)
+- **Next Steps:**
+  1. Continue baseline collection for 2-3 more days (extended from 36h)
+  2. Review baseline data patterns after collection period
+  3. Use baseline for relay.ngit.dev migration decision (issue 820a)
+  4. Consider fixing container stats/FD counts in future if needed

 ### 2026-01-16 [Phase 0 Step 1 - Initial Scripts]
 - Completed: Created three bash diagnostic scripts
 - Issue: Scripts not compatible with NixOS declarative philosophy

 ## Next Steps
 
-1. **10-Minute Check (2026-01-17 23:40 UTC):**
-   - Verify baseline collection is running on all three relays
-   - Check data quality (connection counts, container stats, state breakdown)
-   - Ensure no errors in collection scripts
+1. **Continue Baseline Collection (2-3 more days):**
+   - Current status: ~10.5 hours collected (started 2026-01-17 23:30 UTC)
+   - Extended duration: Continue until 2026-01-20 or 2026-01-21
+   - Reason: Want more data to establish reliable patterns
+   - Critical metrics working: connections, CPU, memory, load average
 
-2. **36-Hour Review (2026-01-19 11:30 UTC):**
-   - Analyze baseline data patterns
+2. **Baseline Review (After 2-3 days):**
+   - Analyze baseline data patterns across full collection period
    - Compare metrics across all three relays
-   - Identify any anomalies or trends
+   - Identify daily patterns, peak hours, resource trends
    - Document findings for relay.ngit.dev migration decision
 
 3. **Migration Decision (Issue 820a):**
    - Use baseline data to inform relay.ngit.dev migration
    - Determine if accelerated migration plan is viable
    - Set timeline for migration execution
+   - Proceed with working metrics (container stats not critical)
