…alloc memory analysis The BE `/memz` web page was removed in #41310 (Support Memory Profile, in Doris since 3.0.4). The raw Jemalloc profile is now shown in the **Jemalloc Profiles** section under **Memory Info** on the Process Profile page `/profile`. Update all `/memz` references in the Jemalloc memory analysis doc (English dev/4.x/3.x and Chinese current/4.x/3.x) to point to `/profile`. The 2.1 docs still reference `/memz` correctly and are left unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Purpose
The BE
/memzweb page was removed in #41310 ([opt](memory) Support Memory Profile), which has been in Doris since 3.0.4 (picked to branch-3.0 via #44945). The current BE code registers no/memzpage — the raw Jemalloc profile (tcache_bytes, theextentstable,Allocated/active/metadata/resident/retained, etc.) is now produced byjemalloc_stats_print(...)in the Jemalloc Profiles section under Memory Info on the Process Profile page/profile(be/src/service/http/default_path_handlers.cpp).The Jemalloc memory analysis doc still tells users to open
http://{be_host}:{be_web_server_port}/memz, which no longer exists (the page is gone;/mem_trackerprints an "offline, please use Process Profile" notice).What changed
Redirect every
/memzreference in the Jemalloc memory analysis doc to/profile, pointing at the Memory Info → Jemalloc Profiles section. All surrounding explanatory content is unchanged.Files updated (3 occurrences each):
docs/.../memory-analysis/jemalloc-memory-analysis.md(English, dev)versioned_docs/version-4.x/.../jemalloc-memory-analysis.mdversioned_docs/version-3.x/.../jemalloc-memory-analysis.mdi18n/zh-CN/.../current/.../jemalloc-memory-analysis.mdi18n/zh-CN/.../version-4.x/.../jemalloc-memory-analysis.mdi18n/zh-CN/.../version-3.x/.../jemalloc-memory-analysis.mdThe
version-2.1docs are intentionally left unchanged:/memzstill exists in 2.1.Notes
The
overview.mdandglobal/query/load-memory-analysis.mddocs in the same directory still reference the removed/mem_tracker?type=*pages. Those require a larger, version-aware rewrite against the newMemoryProfilehierarchy (which differs between 3.x and 4.x) and are intentionally out of scope for this PR.
