AlertSite provides an easy-to-use charting interface to visualize your monitoring data. Response time, availability, and Apdex information collected by your AlertSite monitors can be presented in a customizable chart. Charts can display multiple series of data for easy comparison. You can customize the level of granularity – for example, display raw data or hourly averages.
On the Dashboard, click the monitor tile and then click Compare on the tile toolbar. Switch to the Charting tab.

On the Dashboard, click the group tile and then click Compare on the tile toolbar.
On the Dashboard, click Compare on the main toolbar.
In the list on the left, select the monitors and groups to include in the chart.
|Note:||Selecting a group will replace the previous selection with the monitors from that group. To combine a group with other monitors, select the group first.|
Switch to the Charting tab.
You can add and remove monitors from the chart via the monitor list on the left.
Click next to Selections to display only the selected monitors and to switch back to the monitor selection mode.
By default, the chart includes only successful tests (with status 0). To view all test results, use a Scatter chart with Group By: Raw Data.
Saving and loading chart configurations is not supported for now. You can take screenshots to save the chart on your computer.
The following options can be changed using the toolbar above the chart.
This option lets you switch between raw data and grouped (summary) data.
Raw data means each data point represents a single monitor run. When used together with Chart: Scatter and Color By: Status, raw data helps you get a quick overview of all monitor runs over the selected period.
With large data sets, you may want a quick aggregated view of the data. That is what the grouping options are for. When grouping is used, the X-axis is split into intervals based on the selected unit of measure, and the data points on the chart are the average values for each interval. Data can be aggregated by various classifications, such as Time, Week, Locations, Monitors, and so on.
For example, a chart grouped by Day and Hour shows hourly averages:
Similarly, a chart grouped by location shows the average values for each location:
Grouped charts have drilldown capabilities – you can click a data point or a bar to view the underlying raw data.
A series corresponds to an individual line on a line chart, or same-colored bars on a bar chart. Each series represents a distinct data set, such as the values of a specific metric of a monitor, or the metric values measured from a specific location. Series can be assigned a unique color or data point shape to make the chart easier to understand. The series legend appears to the right of the chart.
Possible series depend on other chart configuration. You can choose between:
For example, using Series By: Location, you can see the response time by location:
Using Series By: Metric you can see the response time broken down into individual network timings:
The chart type – Line (default), Bar, or Scatter.
The time range for the chart. You can select a relative time range, such as Last 24 Hours or This Week, or an exact date range within your data retention period (which is 3 months by default).
When using a relative time period such as Last 1 Hour, click Refresh to update the chart with the latest monitor data. The chart configuration (type, series, and so on) will be preserved.
The Advanced Options button displays all chart options on one screen, so you can quickly make multiple changes. A preview of the configured chart appears on the right.
To return to the chart, click Apply and close or Close. The difference is that Apply and close redraws the chart immediately, whereas Close saves the configuration but does not redraw the chart so you will need to trigger the update manually.
In addition to the options described above, additional options include the following:
Select the locations whose data you wish to include in the chart. Select none to use data of all locations.
Scatter charts can be filtered by the test status:
Show All – all tests regardless of the status.
Show Successes Only – only tests that were successful (status 0, regardless of the full page status).
Show Errors Only – only tests that failed (status other than 0).
If the chart includes multi-step monitors, you can choose to only show the data for specific steps. This option is available for charts with Group By: Raw Data.
To select the steps, expand a monitor and click the desired steps in the list. The selected steps are indicated with a blue color.
Line and scatter charts use a combination of color and shape to indicate different series of values. You can control how the series are displayed by using the options in the legend to the right of the chart. Available options depend on the chart configuration.
Chart colors can be based on:
Status – Available only for charts with Group By: Raw Data and Chart Type: Scatter. Statuses are defined as follows:
Success – Status 0. Test results with warnings and fullpage warnings appear green unless the Show Warnings and Show Full Page Warnings options are selected.
Error – Statuses other than 0.
Full Page Warning – Tests with fullpage status 72xx. This status is used for web page tests where the base page was loaded successfully but there were problems loading some of the page assets (images, scripts, CSS, and so on).
Warning – Tests where the first attempt failed but the second attempt was successful.
Warnings and fullpage warnings are only displayed if the corresponding status options are selected.
|Note:||Some options are only available in certain chart configurations.|
Data points on line and scatter charts can have different shapes to distinguish between different series of data. Shapes can be based on:
Hover over the chart points to see a tooltip with the status at that point, including:
The exact displayed information depends on the chart type and configuration.
When using grouped charts, click a summary data point or a bar to view the raw data for the corresponding interval. Raw data appears as a scatter plot, where each data point represents a monitor run. Click Go Back to return to the main chart.
In raw scatter plots, click a data point for a tooltip with the View Run and View Detail Report links. View Run opens the run results on the Monitor Runs screen. View Detail Report displays the run data in a tabular, printable format as the Detail report.
Drag on the area you want to zoom into. To return to the original chart, click Reset zoom.
