Latency Metrics

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. Latency metrics on the host entity page.

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

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.
