[dpdk-users] Capture EAL Output For Logging

[Cliff Burdick]

Hi, if I have my own logging mechanism, is there a way to capture the EAL
output, especially on startup? The best way I can think of is to open a
pipe to a child process that reads from stdout, and logs from there, but
that seems like somewhat of a hack. I've seen patches that seem like they
may be useful here:

But I believe this just lets you change the syslog facility while the
console messages still go out. I would like to silence EAL to the console
completely, and instead send each line to my custom logger. Has anyone does
this?

The same approach of using pipes has been taken for the CollectD plugin for DPDK[1]; it has proven to work fine. Based on the experience of developing, having a child process with pipes makes it a little more complex to debug, but not drastically so.

Hope that helps! Regards, -Harry
