Triggering memory dump from command line

[mihirtanna]

Is there a way we can trigger a memory dump from command line by providing the process name or ID.
I am looking for a way to automate creating a memory dump using PerfView and would like to know if PerfView accepts command line arguments.

If you're looking to create a full memory dump, then you'll want to use something like procdump or windbg. If you're looking to capture a heap snapshot, then yes, you can do this with PerfView's command line:

Usage: PerfView HeapSnapshot Process [DataFile]

  Take a snapshot of the CLR GC heap of a process.

  Parameters:
    Process                              The process ID or Process Name (Exe without extension) of the process take a
                                         heap snapshot.
    [DataFile]                           The name of the file to place the heap snapshot.

  Qualifiers:
    [-SaveETL]                           Save an ETL file along with the GCDump file when dumping the JS Heap.
    [-MaxDumpCountK:250]                 The maximum number of objects (in K or thousands) to place int the .gcDump
                                         file.  Sample sufficiently to hit this metric.
    [-Freeze]                            Freeze the dump while data is taken.

Thanks Brian for the quick reply!
