pprof:tldr:7354f

The command pprof ${http:--localhost:8080-debug-pprof} is using the pprof tool to collect profiling information from a local web server running on localhost at port 8080.

Let's break it down further:

• pprof: It is a tool provided by the Go programming language for collecting and analyzing profiling information in Go programs.
• ${http:--localhost:8080-debug-pprof}: This is a placeholder for a URL or address where the profiling information is exposed by the web server. It follows the format ${protocol}--${address}.
  • http: This is the protocol. It could be http or https, depending on the server setup.
  • localhost:8080-debug-pprof: This is the address where the profiling information can be accessed. It typically follows the convention of adding /debug/pprof as a route or endpoint to the server.
  • localhost is the hostname or IP address of the local machine. In this case, the server is running on the same machine where the command is being executed.
  • 8080 is the port number on which the web server is listening for incoming requests.
  • /debug/pprof is the route or endpoint that exposes the profiling information.

By executing this command, the pprof tool will make HTTP requests to the specified URL (http://localhost:8080/debug/pprof) to collect profiling data from the web server. The collected data can then be analyzed using the pprof tool to understand the performance characteristics of the server and identify potential bottlenecks or optimization opportunities.
