The vRNI (vRealize Network Insight) / AON (Aria Operations for Networks) user interface shows the error message for the data source:
Something went wrong, please contact support.
VMware Aria Operations for Networks
VMware vRealize Network Insight 6.x
This error message may be transient and often resolves on its own if there are no significant connectivity problems between the Collector and Data Sources.
If the issue persists, try the following steps:
Disable the "Data Collection" via the AON / vRNI UI and wait for 5 minutes.
Re-enable the "Data Collection" via the AON / vRNI UI.
If the problem remains unresolved, collect the AON / vRNI support bundle and open a support case with Broadcom Support.
For additional guidance, refer to the document on Generating support bundles from VMware Aria Operations for Networks appliances(s) and Creating and managing Broadcom support cases.
