jhat: Analyze a heap dump, specifying an alternate port for the http server.

jhat

$ jhat -p ${port} ${dump_file-bin}

try on your machine

The command "jhat -p ${port} ${dump_file-bin}" is used to run the Java Heap Analysis Tool (jhat) with specific configuration options.

Let's break down the command and its parameters:

"jhat": This is the actual command to run the Java Heap Analysis Tool.
"-p": It is a flag that specifies the port number to which jhat will bind. The ${port} is a placeholder for the actual port number you want to use. For example, if you replace ${port} with 8080, jhat will bind to port 8080.
"${dump_file-bin}": It represents the heap dump file name. The heap dump file contains information about Java objects in memory at a specific time. The "${dump_file-bin}" is another placeholder that should be replaced with the actual heap dump file name you want to analyze. For example, if you have a file named "mydump.hprof", you would replace "${dump_file-bin}" with "mydump.hprof".

Overall, the command "jhat -p ${port} ${dump_file-bin}" is used to start the jhat tool, specifying the port on which it will listen for connections and the heap dump file that will be analyzed.
