Does stop-writes-pct watch free-pct-disk?

From Managing Storage | Aerospike Documentation

  • Above the stop-writes-pct level or below the min-avail-pct – Read requests will still be performed, but no more data is written to the database (write requests fail)

Using your terminology, stop write occurred when (free-pct-memory > stop-writes-pct ) OR (free-pct-disk < min-avail-pct)

Note the metrics “stop-writes” is changed to “stop_writes” in 3.9.1, along with other changes that you can find on the metrics page:
