Let's use our same dashboard example to explore how this will work. I am going to ask you to use your imagination a bit for this one in order to understand the technique.
Let's say for a moment that, in our Splunk instance, our Netscaler is doing Gbps worth of throughput and it is taking a very long time to generate the chart from...
