Flags

Long name (short name)	Argument types	Properties
-allObjects(-all)
Ignore any specified or selected objects and peek into all applicable objects. The definition of "allObjects" will vary based on the peek operation being performed - see the flag documentation for details on what it means for a given operation. By default if no objects are selected or specified then it will behave as though this flag were set.
-argument(-a)	string
Specify one or more arguments to be passed to the operation. The acceptable values for the argument string are documented in the flag to which they will be applied. If the argument itself takes a value then the value will be of the form "argname=argvalue". In query mode, this flag needs a value.
-count(-c)	uint
Specify a count to be used by the test. Different tests make different use of the count, query the operation to find out how it interprets the value. For example a performance test might use it as the number of iterations to run in the test, an output operation might use it to limit the amount of output it produces.
-evaluationGraph(-eg)
Ignore any nodes that are not explicitly part of the evaluation graph. Usually this means nodes that are affected either directly or indirectly by animation. May also tailor the operation to be EM-specific in the areas where the structure of the DG differs from the structure of the EM, for example, plug configurations. This is a filter on the currently selected nodes, including the use of the "allObjects" flag.
-operation(-op)	string
Specify the peeking operation to perform. The various operations are registered at run time and can be listed by querying this flag without a value. If you query it with a value then you get the detail values that peek operation accepts and a description of what it does. In query mode, this flag can accept a value.
-outputFile(-of)	string
Specify the location of a file to which the information is to be dumped. Default will return the value from the command. Use the special names stdout and stderr to redirect to your command window. The special name msdev is available when debugging on Windows to direct your output to the debug tab in the output window of Visual Studio.

Flag can appear in Create mode of command	Flag can appear in Edit mode of command
Flag can appear in Query mode of command	Flag can be used more than once in a command.

MEL examples

// Find the available peek operations
dbpeek -op -query;
// Return: metadata nodes references //

// Describe the detail of a single available operation
dbpeek -query -op "nodes";
// Return:
Peek operation 'nodes':
    Normal display  will  show a count of nodes in the scene of each type.
Recognized 'argument' values:
    attributes
        Includes the attribute  count for each node as well, segregated by static, extension, and dynamic types.
    visible
        Filter the display  list to ignore any hidden or internal nodes. Default is to show all nodes.
//
// Describe the detail of a single available operation
dbpeek -op plugIterator -query
// Return: The test 'plugIterator' doesn't take any arguments.
Peek operation 'plugIterator':
    This tests the performance of the class by iterating over all of the
    networked plugs in a plug tree.
    Suggested iteration count minimum is 1000000 for which the test machine
    measured a time of 19.234s.
This operation does not take any arguments.
//

// Run a performance test for 1000000 loops
dbpeek -op plugIterator -count 1000000
// Return: Run 10,000 loops of plug iteration over a tree of size 51, depth 4
Total time:   17.0s
Maximum time: 0.81s
Minimum time: 0.23s
Average time: 0.30s
//

// Run a performance test for 1000000 loops and store the results
dbpeek -op plugIterator -count 1000000 -of "MyFile.txt"
// Return: 0 //
