Check Load Balancer Performance

You should review load balancer performance metrics when experiencing access issues, traffic spikes, configuration changes, or during capacity and cost planning, to determine whether bottlenecks exist at the traffic entry layer.

Listener Metrics

Select all Listeners or a specified listener during a custom time range to check the following performance metrics.

Concurrent Connections (Counts/min) Indicates the number of active connections at a given time. Used to identify connection saturation, long-lived connections, or the need for capacity scaling.

CPS (Connections Per Second / Counts/s) Measures the rate of new connections. Useful for detecting traffic bursts, sudden workload increases, or abnormal connection behavior.

Network Throughput Shows real-time combined inbound and outbound bandwidth rate processed by a load balancing instance within one hour, measured in bits per second (bps). Used to assess whether the load balancer is approaching throughput limits.

Data Transfer Represents the combined inbound and outbound data transfer processed by a load balancing instance within a selected time range, measured in GB. Primarily used for traffic analysis and billing evaluation.

Network Metrics

Select all elastic IPs or a specified IP during a custom time range to check the following performance metrics.

Bandwidth Reflects inbound bytes transferred to and outbound bytes transferred from a public IP address per second. Used to determine whether bandwidth is sufficient or needs to be increased.

Packet Transmission Tracks inbound packets received by and outbound packets transmitted from a public IP address per second. Helpful for diagnosing network quality issues, such as packet bursts or inefficiencies caused by small-packet traffic.
