Mongod.log file missing

I’m not able be locate mongod.log file. I have even search by
sudo find / -type f -name “*.log” | grep mongo

The file is located where you specified where it should be when you start mongod. To help you we need to know how you started mongod. If you specified a config file we need to know what you specified under systemLog:.

ahha… go it…
systemLog was not defined in the config file so all the output was on screen. modified config file and all OK
