HCX Transport Analytics help with monitoring the connectivity health between sites for a Service Mesh and characterizing the underlay network requirements for HCX services.
The Transport Analytics page lists all Service Mesh configurations for a site pair with a separate card for each Service Mesh. Each Service Mesh card contains the same information:
You can use the search option at the top right of the page to find a specific Service Mesh.
- Service Mesh appliances are at version 4.4.0 or later.
- If you have made changes to the uplinks networks in the Compute Profile, navigate to Resync to apply those changes to the Service Mesh. , and click
- In the HCX Manager UI, click Transport Analytics.
The transport analytics page displays the Service Mesh inventory.
- Review each section of the Service Mesh card for health details:
Identifies the source and the destination sites for the site pair.
Performance insights (Currently available for Bulk Migration only)
Based on the bandwidth reported by the uplink test and the bandwidth requirement of the HCX service, HCX calculates underlay network performance associated with the uplink. From that calculation, HCX recommends a number of simultaneous migrations that the underlay network can support at the point when the test was run.
Lists the HCX services enabled in the Service Mesh. Expand each service entry to view the transport thresholds: Minimum Bandwidth, Maximum Latency, and Maximum Loss. The transport thresholds reflect the underlay network requirements for each service.
The health of a service relative to the underlay network is indicated by either a checkmark or an exclamation mark. A checkmark indicates that the underlay network performance meets the minimum requirements for the service, and the uplink network is in a healthy state for the specified HCX service.
An exclamation mark indicates that uplink network is in a degraded state relative to the underlay network performance, and that Uplink is not recommended to use with the specified HCX service.
Provides transport analysis and transport monitoring of the underlay network for each uplink in the Service Mesh.
Transport analysis lists the tested transport thresholds of the underlay network. Expand each uplink network entry to view Available Bandwidth, Latency, and Loss metrics. Select Re-run Test to start a new test for the selected uplink network.
The health of a service relative to the underlay network is indicated by either a checkmark or an exclamation mark. A checkmark indicates that the service thresholds are met for all the services configured in the Service Mesh. An exclamation mark is shown if any one of the service thresholds are not met for the services configured in the Service Mesh.
If a new network uplink is added to the Service Mesh, you must run an initial test on that uplink to generate the transport thresholds. Following the intial test, re-run the test to evaluate the current state of the underlay network.Note:
Available bandwidth is what is currently available at the time of the test. Transport threshold metrics are static and are based on the most recent test. To update the metrics for an uplink network, you must re-run the test.
When an uplink network is used in multiple Service Mesh configurations, each Service Mesh using that uplink is updated with new metrics.
Transport Monitoring provides detailed, time-series bandwidth, latency, and loss information for each uplink network. For more information, see Monitoring Underlay Network Performance Using Transport Monitor.
- (Optional) To view detailed metrics, select Transport Monitor for each uplink network.
- For each Service Mesh card listed under Transport Analytics, review the health details to verify that the underlay network performance meets the requirements for the HCX services enabled for that Service Mesh.
What to do next
If HCX Transport Analytics indicate that the uplink networks are healthy, proceed to using HCX services. If the uplink network status is Degraded, use Transport Monitor to help identify and resolve underlay network performance issues before using HCX services.
