Correct.

Checked against help.splunk.com, August 2026

Concept

Only the attributes present at ingest can identify a series. Anything attached afterwards describes it without changing which series it is.

Why A

Splunk documents that dimensions are sent in with the MTS at ingest and, along with the metric name, uniquely identify the MTS, while custom properties do not contribute to identifying it.

Source

Sent in with metric time series (MTS) at the time of ingest to add context to metrics. Along with the metric name, they uniquely identify the MTS. Dimension names do not change over time.
