Starting with NSX-T Data Center 3.2, the application will support the collection and storage of data up to one year. With this feature, along with the point-in-time data, you can also view time series metrics, such as CPU usage memory, disk usage, packets per second, bytes per second, and packet drop rate, for edge nodes and gateways. You can view the metrics by invoking time series metrics APIs. A few of these metrics are also available on NSX Manager interface along with the point-in-time data.
Using time series metrics, you can monitor the trend in key performance indicators, detect anomalies, perform before and after analysis, and get the historical context which can help in troubleshooting. Based on your role, you can view metrics of only those objects for which you have the authorization.
You can use the metrics APIs to fetch the time series metrics. For information about using the APIs, see APIs to Fetch Time-Series Metrics.
On the NSX Manager interface, the time series metrics is displayed as charts with respective keys and time filter on last one hour, last 24 hours, last one week, last one month, and last one year. You can view the following information for edge nodes:- CPU cores allocated
- Alarms
- Edge node - Overall alarm count
- CPU - Alarms for Datapath CPU and Service CPUs
- Disk - Overall disk alarms and alarms for each partition
- Memory - Overall memory alarms and alarms for each memory pool
- Uptime
- CPU
- System Load - You can view current load average and average system load trend.
- Datapath CPU - Number of datapath CPU cores and their usage details, which include the average usage of all cores and the highest usage among cores. You can view current utilization, highest utilization for a single core, and average usage trend.
- Service CPU - Number of service CPU cores and their usage details, which include the average usage of all cores and highest usage among cores. You can view current utilization, highest utilization for a single core, and average usage trend.
- Memory
- System Memory - Utilization of RAM on edge node. You can view current utilization and average usage trend.
- Datapath Memory - Includes heap memory, memory pool, and resident memory. You can view current usage, current pool usage, and average usage trend.
- Memory Pools - List of all memory pools along with their description and usage values except for QAT memory pool (of Bare Metal Edge) whose usage is always around 100%. The memory pools are:

- Disk
- Total disk usage for all ext4 disk partitions and the list of RAM disk and disk partitions. Also, the available free space of each partition. You can view overall GB used, read latency, write latency, current usage, average usage trend by partition, and average disk latency trend.
- Transport node status
- Network interface
- To view statistics of any network interface, click the graphic icon. You can view cumulative statistics like total packets and dropped packets and time series metrics like network utilization trend and dropped packets trend.
- NAT rules statistics
Prerequisites
If you view statistics without deploying NSX Application Platform or without enabling the Metrics feature, the system displays a message to deploy NSX Application Platform and to enable the Metrics feature.
