Hindsight CLI

The command line interface version of Hindsight is designed for non-real-time use (testing and reporting). The usage is exactly the same as the hindsight executable but the behavior is different.

usage: hindsight_cli <cfg> <log_level>

1. Behavioral Changes Compared to Hindsight

1. It will initiate a shutdown when all inputs plugins have finished
2. It will not exit until all the data has been process by every plugin
3. The ticker_interval is driven by the timestamp in the data (greatest time seen) as opposed to the actual clock time i.e. if an hour of data is processed in 45 seconds a 60 second ticker_interval would trigger the timer_event function 60 times.
4. A second ctrl-c will abort the execution
5. The return value will be non-zero if the execution failed. If the failure was due to plugin termination the return values will be or'ed together e.g., 6 indicates an input and analysis termination.
   • 1 system error
   • 2 input plugin termination
   • 4 analysis plugin termination
   • 8 output plugin termination
