Telegraf uses the standard package net/http/pprof. This package serves via its HTTP server runtime profiling data in the format expected by the pprof visualization tool.
By default, the profiling is turned off.
To enable profiling you need to specify address to config parameter pprof-addr, for example:
telegraf --config telegraf.conf --pprof-addr localhost:6060
There are several paths to get different profiling information:
To look at the heap profile:
go tool pprof http://localhost:6060/debug/pprof/heap
or to look at a 30-second CPU profile:
go tool pprof http://localhost:6060/debug/pprof/profile?seconds=30
To view all available profiles, open http://localhost:6060/debug/pprof/ in your browser.
