Log data often contains seemingly cryptic codes that have all sorts of meanings. This is true of our web access logs, where there is a status code that represents a web page response. This code is very useful, as it can tell us whether certain events were successful or not. For example, error codes found in purchase events are less than ideal, and if our website was at fault, then we might have lost a sale.
In this recipe, we will write a Splunk search to chart web page responses against the various web pages on the site.
