| Application Performance | App response time (total transaction time), server delay (time from server SYN/ACK to first data), client delay (time between receiving response and sending next request), RTT per TCP session | Portal: App dashboards / AppResponse UI: Transaction Analysis > Response Time | Prove whether slow performance is from network or app layer, compare baseline vs after-change performance, identify if client endpoints are causing slowness |
| Transaction Stats | HTTP/S response codes, DNS query/response times and failure counts, SQL/DB query duration and error rates, request/response volume per app | Portal: App KPIs / AppResponse UI: Web/DB/DNS Analysis tabs | Validate if slowness is due to server errors or load, correlate spikes in 500 errors with user complaints, see if a new release broke DNS or DB queries |
| Network Health | TCP retransmissions, packet loss/out-of-order, throughput (bytes/sec), jitter | Portal: Health overview widgets / AppResponse UI: Packets > TCP Analysis | Confirm if poor app performance is caused by network issues, differentiate WAN congestion vs server latency, document evidence for network vs app blame |
| Conversation Summaries | Top talkers (by bytes/sessions), top servers by load, top applications by bandwidth/transactions | Portal: “Top N” widgets / AppResponse UI: Conversations tab | Quickly find which app or host is consuming bandwidth, scope potential DDoS or runaway processes, see if traffic shifted after network changes |
| Alerts / Thresholds | SLA breach alarms (e.g., >2s response), performance anomaly detection, user-defined metric thresholds | Portal: Alert widgets / AppResponse UI: Administration > Thresholds | Early warning of degradations, automated tickets or NOC dashboards, continuous SLA compliance reporting |
