Claiming Anonymous State

When the machine has completely booted, you can claim an existing anonymous state by specifying the -a option with the dtrace command. By default, the -a option claims the anonymous state and processes the existing data, then continues to run. To consume the anonymous state and exit, add the -e option.

When the anonymous state has been consumed from the kernel, the anonymous state cannot be replaced. If you attempt to claim an anonymous tracing state that does not exist, the dtrace command generates a message that is similar to the following example:

dtrace: could not enable tracing: No anonymous tracing state

If drops or errors occur, the dtrace command generates the appropriate messages when the anonymous state is claimed. The messages for drops and errors are the same for both anonymous and non-anonymous state.
