Step Availability

The Step Availability Chart, lets you see the percentage of time a transaction step is in a particular state, such as Up, Down, Warning, Critical, or Unknown. The state of the transaction step at a given time can be determined by referencing the color-coding of the chart and the legend below the chart.

Move the mouse over the main chart to reveal a tool tip with more detailed information for a time slice within the period.


Use the Zoom buttons to display data for 1 hour, 12 week, or 24 hours, or use the slider handles below the chart to create your own period. You can move the selected period to any point in the available data range using the slider bar.
