/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

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/pprof/

Allocs

This endpoint returns a sampling of historical memory allocations over the life of the program.

Method	Path
GET	/sys/pprof/allocs

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/pprof/allocs

Block

This endpoint returns a sampling of goroutines involved in blocking on synchronization primitives.

It is included for completeness, but since Vault doesn't normally enable collection of this data, it won't return anything useful with the standard Vault binary.

Method	Path
GET	/sys/pprof/block

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/pprof/block

Cmdline

This endpoint returns the running program's command line, with arguments separated by NUL bytes.

Method	Path
GET	/sys/pprof/cmdline

Sample request

$ 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

Parameters

• debug (int: 0) - Specifies special arguments for the collection. A value of 2 results in the stack traces being returned as text instead of the default pprof format.

Sample request

$ 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

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/pprof/heap

Mutex

This endpoint returns a sampling of goroutines holding contended mutexes.

It is included for completeness, but since Vault doesn't normally enable collection of this data, it won't return anything useful with the standard Vault binary.

Method	Path
GET	/sys/pprof/mutex

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/pprof/mutex

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

$ 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

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/pprof/symbol

Threadcreate

This endpoint returns stack traces of goroutines that led to the creation of new OS threads.

Method	Path
GET	/sys/pprof/threadcreate

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/pprof/threadcreate

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

$ curl \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/pprof/trace
