A little known, but enormously useful, feature within Foglight is the ability to zoom in and out of the graphs. The flexibility of Foglight's UI has proven to be a big hit with customers and prospects and I shall cover some more tips on this subject over the next few weeks.
This particular tip provides one with the ability to drill into a particular time period or a particular data point.

If we take the middle chart as our starting point, we can hold down the Ctrl button on our keyboard and drag our mouse in the chart. The range we select on the graph will be the are we zoom into. We can continue to zoom in, allowing us to drill down to even greater depth.

As you can see I have zoomed into the chart, showing me with more clarity the CPU utilization. If I wanted to I could zoom further. Note that the zoom applies only to the selected chart. Once I have finished my investigations, I can reset the chart by pressing the 'x' on the top right of the chart (highlighted in red in the screenshot shown above).
Hope this tip helps. If you have any questions or comments, please do not hesitate to post or email me directly at mark.gowdy@quest.com.
