Monitoring IMM (Intersight Managed Mode) UCS Instance Using APIs

[kjain003]

I am trying /api/v1/telemetry/TimeSeries for vnic_stats, vhba_stats, ether_port_stats, and fc_port_stats to retrieve metrics (BytesRx, BytesTx, ErrorsRx, ErrorsTx, DroppedRx, DroppedTx for vNICs/vHBAs; RxBytes, TxBytes, RxErrors, TxErrors, RxDiscards, TxDiscards for ports) but currently getting null response like below.

{
"timestamp": "2025-05-14T12:12:09.594Z",

"result": {
"TxDrops": null,
"RxDrops": null,
"RxErrors": null,
"TxErrors": null,
"RxBytes": null,
"TxBytes": null
}
}
]

here are the API details

can anyone help me with this? Also is there any alternative solution to monitor IMM UCS Instance to fetch above metrics?? We already have https://github.com/paregupt/ucs_traffic_monitor this pipeline in place for UCSM but need something similar for IMM.
