Description
The tracecmd_set_loglevel() function sets the level of the library logs that will be printed on the
console. See libtraceevent(3) for detailed desciription of the log levels. Setting the log level to
specific value means that logs from the previous levels will be printed too. For example TEP_LOG_WARNING
will print any logs with severity TEP_LOG_WARNING, TEP_LOG_ERROR and TEP_LOG_CRITICAL. The default log
level is TEP_LOG_CRITICAL. When a new level is set, it is also propagated to the libtracefs and
libtraceevent.
Example
#include <trace-cmd.h>
...
tracecmd_set_loglevel(TEP_LOG_ALL);
...
/* call libtracecmd, libtracefs or libtraceevent APIs and observe any logs they produce */
...
tracecmd_set_loglevel(TEP_LOG_CRITICAL);
