Logging and Profiling

Simulation Data Inspector, Simulink Scope blocks, File Log blocks, target computer access, profiling

To observe the behavior of your real-time application and the target computer on which it is running, use logging and profiling blocks.

Blocks

File Log	Write signal data file log on target computer
Enable File Log	Enable or disable file logging of signals on target computer
Enable Profiler	Start and stop execution profiler on target computer
Log Event	Log an execution profiling event

Objects

`Target`	Represent real-time application and target computer status
`Target.FileLog`	Target Computer file logger
`Targets`	Configure and manage target objects
`ProfilerData`	Data returned from profiler
`Instrument`	Create real-time instrument object

Functions

`discard`	Delete file log data from target computer
`getAllFileLogBlocks`	Returns block paths corresponding to File Log blocks in application
`getFileLogDecimation`	Returns decimation value of File Log block based on block path
`getProfilerData`	Retrieve profile data object
`list`	Get information about available file logs of signal data
`import`	Import file log data from target computer
`resetProfiler`	Reset profiling service state to `Ready`
`setFileLogDecimation`	Sets decimation value on File Log blocks based on block path and input decimation value
`slrealtime.fileLogImport`	After copying file logs from target to development computer, import file logs into Simulation Data Inspector
`slrealtime.fileLogList`	After copying file logs from target to development computer, list available file logs for import into Simulation Data Inspector
`startProfiler`	Start profiling service on target computer
`startRecording`	Starts signal data live streaming and File Log logging
`stopProfiler`	Stop profiling service on target computer
`stopRecording`	Stops signal data live streaming and File Log logging

Troubleshooting

Troubleshoot Signal Data Logging from Nonvirtual Bus, Fixed-Point, and Multidimensional Signals

Investigate issues that can occur when signal data logging from signals in nonvirtual buses, signals with fixed-point data type, and multidimensional signals.

Troubleshoot Signal Data Logging from Inport in Referenced Model

Investigate issues that prevent some signals from streaming to the Simulation Data Inspector.

Troubleshoot Signal Data Logging from Inport in Referenced Model in Test Harness

Investigate issues that can occur when signal data logging from signals in referenced models in test harnesses.

Troubleshoot Signal Data Logging from Send and Receive Blocks

Investigate issues that can occur when signal data logging from Send and Receive blocks.

Troubleshoot Signals for Streaming or File Logging

Investigate issue related to error that a signal cannot be streamed or logged.
