Reliability Overview

Network reliability analysis based on TCP and UDP performance features. Each asset is profiled per 15-minute window. The reliability engine compares each window against a learned per-asset baseline (drift detection) and configurable SLA thresholds. Degraded windows are recorded in perf_events.

Top Degraded Assets

Assets ranked by number of degraded windows in the time period. A degraded window is one where the asset's performance drifted from baseline OR breached an SLA threshold.

TCP Health

Per-asset TCP performance averages. High reset ratio indicates connection instability. High zero-byte ratio indicates failed handshakes (scanning or blocked services). High short-lived ratio indicates probing patterns.

DNS Health

Per-asset DNS query rate, RTT, and failure ratio. High RTT indicates resolver latency or upstream problems. Low response ratio signals timeouts (queries with no matching answer). High failure ratio (NXDOMAIN/SERVFAIL) indicates misconfiguration or DGA-style probing.

UDP Inter-Arrival Jitter

Per-direction inter-arrival-time stddev. High jitter on streaming ports (5060, 5004, 16384–32767) indicates VoIP / RTP quality issues.
