[dpdk-dev] Question about log levels and rte_panic

[Wiles, Keith]

I have some code I have been debugging that does a rte_panic() at some point. The problem is it just appeared to exit without printing the panic message. I tracked it down to rte_vlog() doing the following test.

 if ((level > rte_logs.level) || !(logtype & rte_logs.type))
      return 0;
 
The reason it appears to just exit to the shell is I was setting —log-level 0 on the command line, which means no CRIT, EMERG or ALERTs panic messages are printed. If I set the log-level 3 then I am able to see these ‘critical’ panic messages, is this the expected behavior?

I would expect EMERG, ALERT and CRIT messages to be printed regardless of the log-level value, but I guess it just means log-level 3 is the lowest level unless you really do not want these messages printed.

Keith
