Network Troubleshooting & Root Cause Analysis
Diagnose LAN/WAN failures and root causes from logs and packet captures
What You Can Do
Upload network logs, packet captures, and configurations to Claude, and it will systematically analyze multi-layer network issues to identify the root cause of connectivity failures, latency problems, and packet loss. You'll get detailed timeline reconstructions, layer-by-layer analysis, and prioritized remediation steps to resolve issues faster.
Features
Example Output
Input: tcpdump packet capture + syslogs showing ping timeouts
Analysis Output:
- Timeline: 14:23:45 – DNS requests timeout → 14:23:50 – TCP retransmits spike → 14:24:10 – ICMP unreachable from 10.0.1.1
- Root Cause: Router 10.0.1.1 hit CPU threshold (94%), dropped ICMP and DNS replies
- Evidence: Syslog shows 'HIGH_CPU_ALERT' at 14:23:40, 10 seconds before first timeout
- Fix: Reduce BGP update frequency from 30s to 60s; restart BGP daemon
Input: Intermittent latency spikes to cloud gateway
Analysis Output:
- Pattern: 500ms latency spikes every 5 minutes, exactly 2 seconds long
- Root Cause: ISP BGP reconvergence on backup link; ECMP hash mismatch on failover
- Fix: Enable BFD (Bidirectional Forwarding Detection) for faster convergence; adjust ECMP seed
