Aruba Edge Connect interface is appearing properly, but interface traffic is missing or blank in SolarWinds Platform 2024.2.1 and below
The article provides information about an issue where Aruba (Silverpeak) edge devices are discovered, and polling data is occurring via API. In some scenarios, the device interface appears, but data related to interface traffic is missing, blank, or incomplete. When testing via SNMP directly to Aruba, all interface traffic is being reported properly.

Cause
This issue occurs due to ifIndex for some Aruba devices may be blank or null. When this scenario occurs, SolarWinds ignores and drops the following data.
Resolution
To properly identify if the ifIndex is blank or null, utilize RestWalk and confirm if the ifIndex is blank or null. Here is an example output of a problematic response:
"publicIp": "", "ifIndex": "", "comboPortSupported": "",
To resolve this issue, please upgrade to SolarWinds Platform 2024.4 and above. There is no available workaround for this problem.
