I have a sample log file from Apache, now how can I identify it with Splunk that this log is really an Apache log are there a tools or any method for that ?
It's not clear what you want to do. Are you trying to tell Splunk how to know a file it is reading is an Apache log? Or are you trying to determine if some search results contain Apache logs? Something else?
I need a command that will help me identify this file as Apache. The result will be the word Apache circled in red(image) .
If you want to search for "Apache" then add "Apache" (with or without quotes) to the query.
One thing missing from the red box is an index specifier, but that's a Best Practice that doesn't address the problem.
Otherwise, it appears as though the query is as complete as it can be without knowing more about the data. If only Apache writes to log.txt then all is good, but if other applications write to the same file name then you'll need to figure out what is unique to Apache data. Another option is to change the input so Apache logs are in a bespoke index or source.
Please teach me, because it's my first time using splunk.
Click on "index" in the Interesting Fields area to see the name of index containing the data. Use that value along with "index=" in the search query.
I'm not an Apache expert so I can't teach you about that. I can help with Splunk-specific questions, though.
