One of the benefits of Verkada’s air quality sensors is simplified alerting capabilities that allow organizations to better understand what is happening in their environments. The Alert Analytics page will make it even easier for organizations to view and analyze their sensor data.
Sensor analytics will give customers a new way to track and monitor alert trends across their organization. Organizations can now understand environmental trends and behaviors at the organization, site, and device levels.
Customers can now specify which readings to evaluate in order to more clearly see how many alerts are generated on a daily, weekly, or monthly basis. First, we added an easy-to-use graph to help identify trends. Next, we implemented a table to show customers the count of total alerts as well as the associated change.
You will find this feature by first Navigating to the Air Quality section of Command, on the right you will see a bar graph icon labeled Analytics. Click the icon to enter the Analytics section of sensors.
Viewing your Alert Data
By default, you will be shown alert analytics across your entire organization, week over week of whatever sensor reading contained the most events over the past week.
If you would like to specify a specific number of sites or subsites, navigate to the pill dropdown on the far right labeled Sites, and individually select the sites you would like to review. If only a portion of the devices in the sites are of interest to you it is recommended that you put those devices into a new subsite.
You will first see your Analytics in a weekly view. You have the option to change this to one of the three options by selecting the middle pill at the top:
Daily - showing day over day for the past week
Weekly - showing week over week for the past 2 months
Monthly - showing month over month for the past year
With the sensor reading pill (leftmost pill), you can select which active reading you would like to review. You may select from any of the Air Quality Sensor Readings available. However, only alerts on configured and supported devices will contribute to the data.
Understanding the Graph
When looking at an analytics graph there will always be one column selected as active. This column will then show a detailed breakdown view for all sites showing the Totals Alerts and referenced Change in the section below. The number above the column will show the total number of alerts that contributed to that column. The previous column will appear in a lighter blue and also show its total above similarly.
The Change column will show you the percentage of change (and total alerts) compared to the past day, week, or month (whichever is selected).
You may select any of the columns to be the active tab however you cannot select the first one in the row. This is because there is no data to previously compare it against within your tab.
Understanding the Table
Within the detailed view, you will see a breakdown of how your selected sites have performed over the time interval compared to their own previous performance. Similarly, you will see in the top left a composite summary of the tab for all selected sites over the time interval.
Totals Alerts shows the sum of all alerts for all devices within the labeled site for the given interval of time. The number above the column and in the summary section on the top left of the page is the total sum of the Totals Alerts for all sites.
Change is the change as a percentage-based reference over the selected interval of time. This type of data is commonly used with understanding the value change of stocks and investments.
A red upward arrow indicates an uptick in alerts over the measured period.
A green downward arrow indicates a decrease in alerts over the measured period.
No change over time is expressed as 0%.
An increase from when there were zero events in the reference column is considered undefined (division by zero) and is expressed as --%.
The most alerts can increase over time is infinite with a 2x increase corresponding to a 100% change.
The most alerts can decrease over time finite converging to 0% where a 2x decrease corresponds to a 50% change.
