Debugging your sensor¶
This section provide some tips you might find useful for sensor debugging.
Making your program abort when an error is displayed¶
When your program use libprelude in a way that doesn't conform to libprelude API usage, libprelude (0.9.15 or higher) will raise a warning:
18 Aug 23:53:18 (process:6744) CRITICAL: assertion 'ptr' failed (idmef-tree-wrap.c:13974 idmef_analyzer_get_name)
This usually mean that you did something wrong, in the above case: calling idmef_analyzer_get_name() with a NULL analyzer argument.
You can use the LIBPRELUDE_ABORT environment variable to force your application to abort if a critical assertion trigger.
Before starting your program, use:
Then if a critical assertion is raised, your program will abort:
$ ./your_program 18 Aug 23:53:18 (process:6744) CRITICAL: assertion 'xxx' failed (filename:line function) Aborted (core dumped)You can set the LIBPRELUDE_ABORT environment variable to any available logging priority:
The CRIT priority will be used in case LIBPRELUDE_ABORT is set to an empty value.
