Monitoring Metrics
Last updated: 2024-11-27 15:00:34
Tencent Cloud Observability Platform (TCOP) collects raw data from the running CLB instances and displays the data entries in intuitive graphs. Statistics will be kept for one month by default. You can observe the operations of instances in the month to stay informed of the status of application services.
You can log in to the TCOP console to view CLB monitoring data. Choose Cloud Product Monitoring > Cloud Load Balancer and then click a CLB instance ID to enter the monitoring details page. You can view monitoring data of the CLB instance, and expand it to view the listener and real server monitoring information.
Note:
For now, the data of concurrent connection utilization and new connection utilization of LCU-supported CLB instances are reported. These data of shared CLB instances are not reported.
