Logging and 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 |
slrealtime.instrument.LineStyle | Create real-time instrument LineStyle object (Since R2022b) |
Properties
| Target Object Properties | slrealtime Target object properties for configuration and status |
Functions
discard | Delete file log data from target computer |
getAllFileLogBlocks | Returns block paths corresponding to File Log blocks in application (Since R2022a) |
getFileLogDecimation | Returns decimation value of File Log block based on block path (Since R2022a) |
getProfilerData | Retrieve profile data object |
list | Get information about available file logs of signal data |
import | Import file log data from target computer |
