@ -25,10 +25,15 @@ You can restrict access to certain functionality by prepending a secret string t
For example, providing the `--admin-prefix=abc123` flag will register the index rebuild path as `/abc123/index/rebuild`.
The restricted paths are:
- `/debug/pprof/`
- `/debug/pprof/allocs`
- `/debug/pprof/block`
- `/debug/pprof/cmdline`
- `/debug/pprof/goroutine`
- `/debug/pprof/heap`
- `/debug/pprof/mutex`

- `/debug/pprof/symbol`
- `/debug/pprof/threadcreate`
- `/debug/pprof/trace`

--case-sensitive use case-sensitive matching for filters
--code enable support for source code files
--code-theme string theme for source code syntax highlighting (default "solarized-dark256")
--compression string compression format to use for index (none, zlib, zstd) (default "zstd")
--compression-fast use fastest compression level (default is best)
--concurrency int maximum concurrency for scan threads (default 2147483647)
-d, --debug display even more verbose logs
