Visualize errors

- [Instructor] The vagrant box is set up…with a web server and a recurring script…that will simulate some web traffic every five minutes.…This will give us something to look at…when we create a dashboard.…You'll start at the search panel…and we'll put in 404 and source type,…equals access combined.…You can see it was one of the options that auto completed.…This will show us just 404,…that is file not found messages,…that have been piling up in the web server access log.…

So let's click search.…You may have noticed before that there's a little graph…at the top of the search results.…Go over to Format Timeline…and select Full to get a better view.…This is the most basic visualization…that you get with Splunk.…And it will only really show you event counts over time.…In order to get this into a friendlier visualization format,…we'll need to tell Splunk…what we actually want to visualize.…

Since this is just 404 errors,…an error count indexed against time should work.…To do that, I'll add the command timechart count,…
