Data reports
CloudLens for CLB provides the Monitoring Overview, Monitoring Center, Real-time Monitoring, Instance Inspection, and Access Overview dashboards to help you monitor CLB instances from different perspectives.
Prerequisites
The log collection feature must be enabled for the target CLB instance. For more information, see Enable the data collection feature.
Access
- Log on to the Log Service console.
-
In the Log Application section, on the Cloud Service Lens tab, click CloudLens for CLB.
-
In the left-side navigation pane, click Report Center.
-
In the upper-left corner of the page, select the target CLB instance.
Monitoring Overview
The Monitoring Overview dashboard shows key monitoring metrics for the CLB instance, including core indicators, error codes, traffic, exception events, PV, access success rate, and average latency.
Monitoring Center
The Monitoring Center dashboard shows real-time monitoring data for the CLB instance, including PV, request success rate, average latency, 4xx request count, status code distribution, traffic, P50/P90/P99 latency, and top hosts, URLs, and backend instances ranked by request count, latency, and failure rate.
Real-time Monitoring
The Real-time Monitoring dashboard shows CLB instance metrics aggregated at one-second intervals, including QPS, access latency, upstream latency, success rate, request traffic, response body traffic, 2xx/3xx status codes, error codes, and upstream 2xx/3xx status codes and error codes.
Instance Inspection
The Instance Inspection dashboard uses Simple Log Service machine learning algorithms to automatically detect anomalies in the CLB instance. It shows the total number of anomalies, severity distribution, anomaly list, and exception events.
Access Overview
The Overview dashboard shows the overall access status of the CLB instance, including day-over-day and week-over-week PV and UV trends, PV and UV distribution, PVs Today, PVs of 7 Days, top 10 provinces, hosts, user agents, and IPs by PV, and the percentage of mobile users.
The dashboard also shows the traffic topology, which visualizes the traffic path from user requests through CLB to backend instances. The topology includes ingress traffic, egress traffic, average request latency, and error rate statistics such as the 404 rate and the 5xx rate.
