The Java Heap Analysis Tool (JHAT) is used to parse Java heap dump files. The syntax for this heap dump file parsing tool is as follows:
jhat [-stack <bool>] [-refs <bool>] [-port <port>] [-baseline <file>] [-debug <int>] [-version] [-h|-help] <file>
Here is a quick look at the options associated with the JHAT command:
| Option | Description | Default |
| -J<flag> | This passes <flag> to the runtime system. | N/A |
| -stack<bool> | Toggles tracking of object allocation call stack. | true |
| -refs<bool> | Toggles tracking of references to objects. | true |
| -port<port> | Indicates the port for the JHAT HTTP server. | 7000 |
| -exclude<exclude-filename> | Exclude indicated file from reachable objects query. | N/A |
| -baseline<filename> ... |
