Splunk One of the killer tools to hit the IT operations world in recent years is Splunk. Splunk indexes log files and other textual data that includes timestamps (which most of the data sources we describe above can be configured to provide) across your whole data center. You can then perform real-time searches that let you pinpoint unusual events and do root-cause analysis of what’s going on. Splunk can even used as an operations dashboard, and be configured to send notifications.
