Ready to build out a FluentD conf file?<\/p>\n

 <\/p>\n

Let’s build a FluentD conf file.\u00a0 We can use the docs site<\/a> for another example.\u00a0 And now, let’s build a simple FluentD configuration file. Paste the XML code below, and save as <yourlogfile>.conf<\/p>\n

cd \/etc\/opt\/microsoft\/omsagent\/scom\/conf\/omsagent.d\/<\/span>
