--- layout: api page_title: /sys/pprof - HTTP API sidebar_title: /sys/pprof description: The `/sys/pprof` endpoint is used to query profiling information. --- # `/sys/pprof` The `/sys/pprof` endpoint is used to query. The response returned by these endpoints are equivalent to those returned by the `http/pprof` package. ## Index This endpoint returns an HTML page listing the available profiles. | Method | Path | | :----- | :------------ | | `GET` | `/sys/pprof/` | ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/sys/pprof/ ``` ## Cmdline This endpoint returns the running program's command line, with arguments separated by NUL bytes. | Method | Path | | :----- | :------------------- | | `GET` | `/sys/pprof/cmdline` | ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/sys/pprof/cmdline ``` ## Goroutine This endpoint returns stack traces of all current goroutines. | Method | Path | | :----- | :--------------------- | | `GET` | `/sys/pprof/goroutine` | ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/sys/pprof/goroutine ``` ## Heap This endpoint returns a sampling of memory allocations of live object. | Method | Path | | :----- | :---------------- | | `GET` | `/sys/pprof/heap` | ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/sys/pprof/heap ``` ## Profile This endpoint returns a pprof-formatted cpu profile payload. Profiling lasts for duration specified in seconds GET parameter, or for 30 seconds if not specified. | Method | Path | | :----- | :------------------- | | `GET` | `/sys/pprof/profile` | ### Parameters - `seconds` `(int: 30)` - Specifies the duration to run the profiling command. This value is specified as a query parameter. ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/sys/pprof/profile ``` ## Symbol This endpoint returns the program counters listed in the request. | Method | Path | | :----- | :------------------ | | `GET` | `/sys/pprof/symbol` | ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/sys/pprof/symbol ``` ## Trace This endpoint returns the execution trace in binary form. Tracing lasts for duration specified in seconds GET parameter, or for 1 second if not specified. | Method | Path | | :----- | :----------------- | | `GET` | `/sys/pprof/trace` | ### Parameters - `seconds` `(int: 1)` - Specifies the duration to run the tracing command. This value is specified as a query parameter. ### Sample Request ```shell-session $ curl \ --header "X-Vault-Token: ..." \ http://127.0.0.1:8200/v1/sys/pprof/trace ```
