Latency metrics provide information about the latency of a network. You can monitor the latency to diagnose and troubleshoot performance bottlenecks in your network.
Viewing Latency Metrics
To view the latency metrics on the user interface, do the following:
- Enter Host, VMware VM, or NSX-T transport node on the search bar. Latency metrics are available only for these entities.
- On the search results page, click the entity you want to view.
- On the entity page, select the Metrics tab to view the latency metrics available for that entity.
Note:
To view latency metrics, you must have selected the Enable latency metric collection check box when adding NSX-V and NSX managers as data sources in VMware Aria Operations for Networks.
Interface Pair Metrics
Interface pair metrics provide information regarding the latency of the data packets traveling between the source and destination VXLAN tunnel endpoints (VTEPs) or virtual network interface cards (vNICs).
| Metric Name | Metric API Name | Description |
|---|---|---|
| Max Interface Latency | netopa.interfacePairLatency.absolute.maximum.microsecond | Maximum round-trip time taken by the data packet to travel from VTEP to VTEP or from vNIC to vNIC. |
| Min InterfaceLatency | netopa.interfacePairLatency.absolute.minimum.microsecond | Minimum round-trip time taken by the data packet to travel from VTEP to VTEP or from vNIC to vNIC. |
| Interface Latency | netopa.interfacePairLatency.absolute.average.microsecond | Average round-trip time taken by the data packet to travel from VTEP to VTEP or from vNIC to vNIC. |
Interface pNIC Pair Info Metrics
Interface Physical Network Interface Card (pNIC) pair info metrics provide information about the following network latency statistics:
- pNIC to vNIC
- vNIC to pNIC
| Metric Name | Metric API Name | Description |
|---|---|---|
| Max pNIC vNIC Latency | netopa.pnicInterfaceLatency.absolute.maximum.microsecond | Maximum round-trip time taken by the data packet to travel from pNIC to vNIC. |
| Max vNIC pNIC Latency | netopa.interfacePnicLatency.absolute.maximum.microsecond | Maximum round-trip time taken by the data packet to travel from vNIC to pNIC. |
| Min pNIC vNIC Latency | netopa.pnicInterfaceLatency.absolute.minimum.microsecond | Minimum round-trip time taken by the data packet to travel from pNIC to vNIC. |
| Min vNIC pNIC Latency | netopa.interfacePnicLatency.absolute.minimum.microsecond | Minimum round-trip time taken by the data packet to travel from vNIC to pNIC. |
| pNIC vNIC Latency | netopa.pnicInterfaceLatency.absolute.average.microsecond | Average round-trip time taken by the data packet to travel from pNIC to vNIC. |
| vNIC pNIC Latency | netopa.interfacePnicLatency.absolute.average.microsecond | Average round-trip time taken by the data packet to travel from vNIC to pNIC. |
