+## Continuous dumps
+
+By default, the heap profiler captures all the allocations from the beginning of
+the recording and stores a single snapshot, shown as a single diamond in the UI,
+which summarizes all allocations/frees.
+
+It is possible to configure the heap profiler to periodically (not just at the
+end of the trace) store snapshots (continuous dumps), for example every 5000ms
+
+* By setting "Continuous dumps interval" in the UI to 5000.
+* By adding
+  ```
+  continuous_dump_config {
+    dump_interval_ms: 5000
+  }
+  ```
+  in the
+  [HeapprofdConfig](/docs/reference/trace-config-proto.autogen#HeapprofdConfig).
+* By adding `-c 5000` to the invocation of
+  [`tools/heap_profile`](/docs/reference/heap_profile-cli).
+
+![Continuous dump flamegraph](/docs/images/heap_prof_continuous.png)

+The resulting visualization shows multiple diamonds. Clicking on each diamond
+shows a summary of the allocations/frees from the beginning of the trace until
+that point (i.e. the summary is cumulative).
