Currently there is no way to set the log file permissions from Ops Manager and the default value is 600. Our organization uses Splunk and with the current settings the Splunk user is not able to read the log files. Config file options such as processUmask and honorSystemUmask can be used to change the log file permissions, but they will also change other files such as journal files, wiredtiger files, etc. The only option we have is to add the Splunk user to our role group in Unix, but this causes a security issue.
