You can consume the provided data with go tool pprof to generate output in many formats (PDF, DOT, PNG, etc).

• allocs: A sampling of all past memory allocations
• cmdline: The command line invocation of the current program
• goroutine: Stack traces of all current goroutines
• mutex: Stack traces of holders of contended mutexes

This data is served over the admin-http port. To find this port, you can examine the pod’s yaml, or for the identity pod for example, issue a command like so:

It is now possible to use go tool to inspect this data. For example to generate a graph in a PDF file describing memory allocations:
