Lets suppose if I am injegsting logs through standard syslog which does not conform with standard syslog RFC; would it be possible to parse the logs in graylog once they hit Graylog? Or do I need to put logstash in between and then work on GROK patterns?
Can someone please advise?
And if changing logos and NASA image is the same procedure with 2.4 as well?
Thanks and Regards,
