 You can periodically dump profiling data and compare them to find the delta memory usage.
 
+### Symbolicate external dump files
+
+If you have jemalloc heap dump files generated externally (e.g., via `MALLOC_CONF="prof:true,prof_prefix:jeprof.out,lg_prof_interval:26"` or `prof_gdump`), you can upload them to a running GreptimeDB instance for symbolication and flamegraph generation:
+
+```bash
+# Upload a jemalloc heap dump file and get a symbolicated flamegraph
+curl -X POST --data-binary @/path/to/jeprof.out.12345.0.i0.heap \
+  localhost:4000/debug/prof/mem/symbol > flamegraph.svg
+```
+
+This is useful when:
+- You collected heap dumps from a production environment
+- You want to symbolicate dumps on a machine with debug symbols
+- You need to analyze dumps generated by jemalloc's automatic dump mechanisms
+
 ## Analyze profiling data with flamegraph
 
 To create flamegraph according to dumped profiling data:
