VMware Aria Operations for Networks collects many metrics for NSX Advanced Load Balancer, including controller metrics, pool metrics, pool member metrics, service engine metrics, and virtual service metrics.
Controller Metrics
| Metric Name | Metric API Name | Description |
|---|---|---|
| CPU Usage Rate (%) | cpu.usage.rate.average.percent | Average percentage of the CPU used out of its total capacity.
Note:
This metric provides the host's view of the CPU usage and not the guest operating system view. It is the average CPU utilization over all available virtual CPUs in the virtual machine. |
| Disk Usage Rate | disk.used.absolute.latest.percent | Average percentage of the disk used out of its total capacity. |
| Memory Usage Rate | mem.usage.absolute.average.percent | Average percentage of the memory used out of the total configured memory. |
Pool and Pool Member Metrics

| Current Connections | net.lbPoolCurrentConnections.absolute.latest.number | Number of current connections processed by this pool during the time interval. |
| Health Score | nsxalb.healthScore.absolute.latest.number | The score indicating the health of the pool. |
| Lossy Connections | nsxalb.lossyConnections.delta.summation.number | Number of lossy connections during the time interval between the service engine and the server. |
| Network Packet Count | net.packetsTotal.delta.summation.number | Total number of received and transmitted packets processed by this pool during the time interval. |
| Network Rx Rate (kbps) | net.received.rate.average.kiloBitsPerSecond | Average rate of received packets processed by this pool during the time interval. |
| Network Traffic Rate (kbps) | net.usage.rate.average.kiloBitsPerSecond | Average rate of received and transmitted packets processed by this pool during the time interval. |
| Network Tx Rate (kbps) | net.transmitted.rate.average.kiloBitsPerSecond | Average rate of transmitted packets processed by this pool during the time interval. |
| Rx Packets | net.packetsRx.delta.summation.number | Total number of received packets processed by this pool during the time interval. |
| Server Responses | nsxalb.l7ServerResponse.delta.summation.number | Total number of server HTTP responses handled by the pool during the time interval. |

Service Engine Metrics
| Metric Name | Metric API Name | Description |
|---|---|---|
| CPU Usage Rate (%) | cpu.usage.rate.average.percent | Average percentage of the CPU used out of its total capacity.
Note:
This metric provides the host's view of the CPU usage and not the guest operating system view. It is the average CPU utilization over all available virtual CPUs in the virtual machine. |
| Dropped Rx Packets | net.droppedRx.delta.summation.number | Average number of received packets in NSX Advanced Load Balancer virtual services and NSX Advanced Load Balancer non-virtual services dropped during the selected duration. |
| Health Score | nsxalb.healthScore.absolute.latest.number | The score indicating the health of the service engine. |
| Memory Usage Rate (%) | mem.usage.absolute.average.percent | Average percentage of the memory used out of the total configured memory. |
| Network Packet Count | net.packetsTotal.delta.summation.number | Total number of received and transmitted packets processed by all the vNICs of the service engine (VM) during the selected duration. |
| Network Rx Rate (kbps) | net.received.rate.average.kiloBitsPerSecond | Average rate of received packets across all the VNICs of the service engine. |
| Network Traffic Rate (kbps) | net.usage.rate.average.kiloBytesPerSecond | Average rate of received and transmitted packets across all the VNICs of the service engine. |
| Network Tx Rate (kbps) | net.transmitted.rate.average.kiloBitsPerSecond | Average rate of transmitted packets across all the VNICs of the service engine. |
| Network Tx Rate (kbps) | net.transmitted.rate.average.kiloBytesPerSecond | Average rate of transmitted packets across all the VNICs of the service engine. |
| Rx Packets | net.packetsRx.delta.summation.number | Number of packets received by all the vNICs of the service engine (VM) during the selected duration. |
| Session Count | net.connection.delta.summation.number | Number of connections to the service engine during the time interval. The number of connections include the dropped connections and the connections lost due to policy drops. |
| Tx Packets | net.packetsTx.delta.summation.number | Number of packets transmitted by all the vNICs of the service engine during the selected duration. |
