Supported `--aggregate` values: `Average`, `Minimum`, `Maximum`, `Total`, `Count`, `Start`, `End`,
`StandardDeviation` (aliases: `avg`, `min`, `max`, `total`, `stddev`/`stdev`, `first`, `last`).
Supported `--aggregate` values: `Average`, `Minimum`, `Maximum`, `Count`, `Start`, `End`,
`StandardDeviation` (aliases: `avg`, `min`, `max`, `stddev`/`stdev`, `first`, `last`).
`--interval` is the processing interval in milliseconds (default 3600000 = 1 hour).
`Total` is derived client-side as time-weighted Average × interval-seconds (see "Total aggregate
derivation" above).
The `Total` aggregate is served by the server's OPC UA HistoryRead endpoint for any conformant
client (derived as time-weighted Average × interval-seconds — see "Total aggregate derivation"
above), but is not exposed by this bundled CLI.
