vRealize Network Insight collects NSX-T transport node metrics to monitor the performance of NSX-T transport nodes and troubleshoot issues, if any.
NAT Metrics
NAT metrics provide information about the total traffic consumed by the service router for the NAT (Network Address Translation) rules configured on the NSX-T transport node.
| Metric Name | Metric API Name | Description |
|---|---|---|
| Flow Packet Count | flow.totalPackets.delta.summation.number | Sum of packets processed by all the NAT rules from all logical routers which are present on the transport node. |
| Session Count | net.connection.delta.summation.number | Sum of connections of all NAT rules from all logical routers which are present on the transport node. |
| Total Traffic | flow.totalBytes.delta.summation.bytes | Sum of bytes of all NAT rules from all logical routers which are present on the transport node. |
Node Metrics
Node metrics provide information about the CPU usage and the system load of the NSX-T transport node.
| Metric Name | Metric API Name | Description |
|---|---|---|
| CPU Usage (%) | sys.loadFifteenMinutes.rate.latest.percent | Percentage of CPU used out of its total capacity in the time interval. |
| Fifteen Minute Load Average | sys.loadFifteenMinutes.absolute.maximum.number | Average system load over an interval of fifteen minutes. |
| Five Minute Load Average | sys.loadFiveMinutes.absolute.maximum.number | Average system load over a period of five minutes. |
| Memory Cache | mem.cache.absolute.latest.kiloBytes | Total memory used by the system for disk caching in the time interval. |
| Memory Usage | mem.usage.absolute.latest.kiloBytes | Total amount of memory used by the system, including swap memory, in the time interval. |
| Memory Usage Rate (%) | mem.usage.absolute.latest.percent | Average percentage of the memory used, including swap memory, out of the total available memory. |
| One Minute Load Average | sys.loadOneMinute.absolute.maximum.number | Average system load in a minute. |
| Swap Memory Usage | mem.swapused.absolute.latest.kiloBytes | Amount of swap memory used by the system in the time interval. |
| System Uptime (ms) | sys.uptime.absolute.latest.millisecond | Total time elapsed since the last system startup. |
