Understanding Check Details

The Check Details view provides detailed information about a single check in a number of charts, graphs and tables:

Bookmarks

When you open a certain Check Result from within the Check Details page, the Check Result will open in a new tab within the ASM GUI called a “Bookmark”:

When you access another Check Details page and then open a Check Result from that same Check Details page, the new Check Detail and Check Result will also be populated in the bookmark:

The bookmarks can be re-ordered by clicking and dragging them. This allows you to keep a number of checks in the bookmarks bar and move between them by clicking the respective bookmark. Clicking a bookmark will take you to the corresponding Check Details or Result Details view.

Response Graph

The Response Graph displays the response times over the selected period as a curve and provides access to the functions described in the Toolbar. The default view is called the “Chart View”:

 

By mousing over your Check Details graphs, you'll notice a popup at various points, specifying a check run and showing its date and result:

Clicking on a check run will open the Result Details page.

It is possible to zoom further into certain sections of the response graph by clicking and dragging a small portion of the response graph:

 

After you click, drag, and release, you will see the graph has zoomed in to the timeframe you have dragged over:

The Response Graph toolbar contains buttons for a number of actions relating to the graph.

Show Custom Events

By checking the “Show Custom Events” checkbox, you can view any Custom Events that you have configured for the check. For instance, if you would like your users to know that there is planned maintenance for a check during a specific timeframe, you can set up the corresponding event as a Custom Event and check the box. A bar denoting the event will appear underneath the response graph:

If you click on the Custom Event bar, you can view the Custom Event Information:

If a custom event applies to a check for which you are viewing details, you will see a section on the Check Details page entitled “Custom Events Last 24 Hours” which displays the event name and duration:

Compare Checks

One of the buttons available in the Toolbar, the “Compare” button, allows you to compare the results of two check runs. Using the Compare function, you can easily overlay the recent results of multiple checks into a single view. As practical examples, you might want to compare how the same check performs in different geographical locations, compare a group of checks from the same location, or compare all checks of a specific type in order to “visualize” any patterns you might observe in the results.

To begin a check comparison:

1. open any Check Details page and click Compare from the Response Time widget:

2. Choose one or more checks to compare in the “Compare” box which pops up:

3. Click each Check you wish to include in the comparison. They will populate the Checks fields as icons, showing some basic information about each check:

If you have many checks, typing a few letters will filter the list alphabetically. Click any check in the results to add it to the Checks field. To delete a Check from the list, click the “X” to the left side of each check icon. If you have AppDynamics, Akamai, or Google Analytics integrations configured, you may add integration information to your comparison.

4. Click Save at the bottom of the Compare pop-up, and the graph view will display a comparison of the checks you selected. Each check will create a series with a separate color. You can toggle the visibility of the comparison graph by clicking the series at the bottom of the graph. All check viewing tools are available, including hovering over check points, clicking check points for further details, zooming, and dragging:

Response Table

The Response Table displays check response times in table form. This is called the “Table View”:

The Response Table toolbar contains buttons for a number of actions relating to the table.

Attempts

The number of attempts to run the check. If there is more than one check run attempt, the attempt pause specified in the Edit Check page will be applied. If failover is enabled, the check will run the number of defined of attempts plus one more attempt - a final attempt from the failover location

SLA Graph

Successful and failed SLA samples are shown in the SLA graph. SLA samples are determined by check response times.

A bar graph shows the percentage of time the SLA setting is being met over time. The legend shows the average SLA% values for Success (green) and Fatal (red) runs. Clicking a legend item will remove that type of result from the chart.

Display Selection

You can filter the results to show all recent data by hours, days, weeks or by using the last 12h/24h/7d/current month/previous month/year buttons, then sort further using the calendar date selection tool.

Show

In the Show area, you can select a time period to display by entering a number in the field and selecting period (hours, days, weeks, months, quarters, years) in the dropdown menu.

Last

In the Last area, you can quick-select a time period to display by clicking one of the buttons (12h, 24h, 7d, current month, previous month, year).

Longer time periods are displayed in From and To fields. You can further modify the time period by manually entering date values and clicking “Refresh”.

*Apdex (Application Performance Index) is an open standard that defines a standard method for reporting and comparing the performance of software applications in computing.

Apdex = (Satisfied Count + Tolerating Count / 2) / (Satisfied Count + Tolerating Count + Frustrated Count)

See ApDex on Wikipedia for more information.

The following equation shows how Apdex is calculated in Apica Synthetic Monitoring Portal:

  • Satisfied Count = Total count of Informational samples

  • Tolerating Count = Total count of Warning samples

  • Frustrated Count = Total count of Error and fatal samples

Apdex = (I + W / 2) / (I + W + E + F)

Status Graph

The “Status Last 24 Hours” graph displays an overview of the checks that have run in the last 24 hours.

The general information subsection of the Status Graph section shows general information about the check.

Last Value

Response time for the last run. A color will be assigned to the Last Value value in accordance with the Severity Handling rules of the check (if applicable). For example, if the check’s last value passes the High Warning Threshold, the last run will be assigned a Warning severity and the Last Value will take on the color yellow in accordance with the Warning severity color

24 status

A graphical representation of the last 24 statuses. The color of each bar reflects the final check run status for each hour. That is, if the last run of a check during a certain hour returned Fatal, then the bar representing that hour in the “24 status” section will be Red (there will be a red section in the bar).

Trends

The Trends graph displays top-level information about the behavior of the check over time. These metrics deliver a convenient and useful report on how your check is performing at a glance.

In the above example, you could use the graph to determine the Mean user journey response time for 2023-04-10 vs. 2023-04-11.

Hovering over a data point in the graph provides the check run date, name and response time:
