You can use the metrics APIs to fetch the time series metrics.
These APIs that can take multiple intent paths as input for a specific resource type, such as edge or gateway, and return the corresponding metrics. For complete information about how to invoke the time series metrics APIs, see NSX Intelligence & NSX Application Platform API Guide.
The following list contains terms and their descriptions related to metrics APIs.
Term | Description |
---|---|
Resource type | Any entity, such as edge node or gateway, for which metrics is available. |
Resource ID | Intent path or an identifier for a resource type. |
Object | Sub-entity of a particular resource type. For example, firewall rule within a ruleset. |
Metric key | Unique key assigned to a metric of any resource. Following metric keys are examples of keys available for edge nodes and NSX Manager:
Following metric keys are examples of keys available for gateway firewalls:
You can use the following API to fetch metric keys of any required resource.

Perform the following steps to fetch metrics for a required resource. Note that metric keys used in examples are for the purpose of sample only. Use the appropriate API to fetch actual keys and descriptions.
Step 1: Select the resource type for which you want to fetch the time-series metrics
- PolicyEdgeNode
- ClusterNode
- Tier0Interface
- Tier1Interface
- Tier0
- Tier1
Starting with NSX 4.0.1.1, you can also view time series metrics for VPN by using the following resource types.
- PolicyBasedIPSecVpnSession
- RouteBasedIPSecVpnSession
Step 2: Get supported metric keys and their information for a resource type
Use the following API to get supported metric keys for a resource type. The API takes resource_type as a query parameter and list all metrics that are available for that resource. This API also provides description and units for each metric.
URI Path:
GET https://<manager>/napp/api/v1/metrics/key-info?resource_type=<resource_type>
Example:
GET https://<manager>/napp/api/v1/metrics/key-info?resource_type=PolicyEdgeNode
Response:
{ "results":[ { "metric_key ":"edge.cpu_usage", "metric_unit":"PERCENT", "description":"Edge Cpu usage percentage" }, { "metric_key":"edge.pnic_avg_rx_packets", "metric_unit":"PER_SECOND" "description":"Average Rx packets per second" } ] } }
Step 3: Get object information for a resource and a metric key
Use the following API to get the object information of a metric key for a required resource type.
URI Path:
POST https://<manager>/napp/api/v1/metrics/object-info
Example Request:
{ "resource_type":"PolicyEdgeNode", "resource_ids": [ "/infra/sites/default/enforcement-points/default/edge-clusters/57d2c653-4d63-48d8-b188-40b4e45a9bc8/edge-nodes/2ed9af04-21c9-11e9-be65-000c2902dff7", "/infra/sites/default/enforcement-points/default/edge-clusters/57d2c653-4d63-48d8-b188-40b4e45a9bc8/edge-nodes/1349af04-21c9-11e9-be65-000c2902d0000" ], "keys": [ "edge_cores.cpu_usage", "edge.pnic_avg_rx_packets"], "start_time":1603971420 "end_time": 1603973420 "granularity": "5M", "max_num_data_points": 10 }
Example Response:
{ "start_time": 1603971420, "end_time": 1603973420, "resource_type": "PolicyEdgeNode", "results": [ { "resource_id": "/infra/sites/default/enforcement-points/default/edge-clusters/57d2c653-4d63-48d8-b188-40b4e45a9bc8/edge-nodes/2ed9af04-21c9-11e9-be65-000c2902dff7", "key_results": [ { "key": "edge.pnic_avg_rx_packets", "unit": "PER_SECOND", }, { "key": "edge_core.cpu_usage", "results": [ { "object_id": "core1", "node_id": "2ed9af04-21c9-11e9-be65-000c2902dff7", "node_path": "/infra/default/edge/1", node_name": "Edge1", }, { "object_id": "core2", "node_id": "2ed9af04-21c9-11e9-be65-000c2902dff7", "node_path": "/infra/default/edge/1", "node_name": "Edge1", } ] } ] }, { "resource_id": "/infra/sites/default/enforcement-points/default/edge-clusters/57d2c653-4d63-48d8-b188-40b4e45a9bc8/edge-nodes/1349af04-21c9-11e9-be65-000c2902d0000", "key_results": [ { "key": "edge.pnic_avg_rx_packets", "unit": "PER_SECOND", "description": "Average packet per second (PPS) network utilization on ingress on the the management interface(s)", } ] } ] }
Step 4: Fetch metrics data
Use the following API to fetch metrics data.
URI Path:
POST https://<manager>/napp/api/v1/metrics/data
Example Request:
{ "resource_type":"PolicyEdgeNode", "resource_ids": [ "/infra/sites/default/enforcement-points/default/edge-clusters/57d2c653-4d63-48d8-b188-40b4e45a9bc8/edge-nodes/2ed9af04-21c9-11e9-be65-000c2902dff7", "/infra/sites/default/enforcement-points/default/edge-clusters/57d2c653-4d63-48d8-b188-40b4e45a9bc8/edge-nodes/1349af04-21c9-11e9-be65-000c2902d0000" ], "object_ids": ["core1" ,"core2"], "node_ids": [], "keys": [ "edge_cores.cpu_usage", "edge.pnic_avg_rx_packets"], "start_time":1603971420 "end_time": 1603973420 "granularity": "5M", "max_num_data_points": 10 }
Example Response:
