Extremely basic debug/dump tool. Should work against 32-bit or 64-bit processes.
All usages expect either a running process or a dumpfile as their input.
- Processes may be specified by PID, name, or prefix of IIS app pool name. If the name is ambiguous, matching processes will be summarised so that the precise PID may be more easily identified.
- Attachment to a process will be noninvasive unless the -x switch is specified. This will usually pause the target process, so beware when using it against production systems.
- Some commands require invasive attachment and therefore require the -x switch when working with live processes.
- Consuming information from dumpfiles never requires the -x switch.
clrspy showstacks [-v] [-x] [-p <pid>] [-n <name>] [-a <app-pool>] [-d <dumpfile>]
Writes stack traces and object types to STDOUT. May inspect either a dumpfile or a running process. Generally a fast operation. The -x switch permits retrieval of more accurate information.
clrspy showheap -x [-v] [-p <pid>] [-n <name>] [-a <app-pool>] [-d <dumpfile>]
Writes tabulated heap usage statistics to STDOUT, grouped by object type and in descending order of total allocated size. May take some time to run, and it requires -x.
clrspy dumpmemory -x [-d <dumpfile>] [-v] [-p <pid>] [-n <name>] [-a <app-pool>] [-f]
Create a full memory dumpfile from a process. Includes the process's entire memory space and symbol tables if possible.
If the dumpfile is not specified,memorydump-<pid> will be used instead.
May take some time to run, and it requires -x.
