In industry and production scenarios a lot of machine data is available. This can include the temperature of certain machines, time spans of certain processes, system pressure, power consumption, vibration detection, etc. The data is (or can be made) available in database tables and sometimes it is already being displayed on dashboards on computer screens. In daily operations, it is hard to look at each relevant dashboard all the time. Therefore, it makes sense to send relevant information about critical situations to the responsible users in real time no matter where they are. That is where SIGNL4 comes in.
Integrating SIGNL4 with any database can enhance your daily operations with an extension to your mobile team in the field or on the shop floor.
How it Works
All it takes to check relevant information and send alerts using SIGNL4 is a little script with a suitable SQL query that checks the database in regular intervals.
Tickets and Incidents are sent to SIGNL4
Event categorization, routing and automated delivery
Persistent Notifications by push, text and voice call with Tracking, Escalation and Confirmation to Staff on Duty
HOW TO INTEGRATE
SIGNL4 is a mobile alert notification app for powerful alerting, alert management and for mobile assignment of work items. Get the app at https://www.signl4.com.
Microsoft SQL Server is a widely used database. Of course any other database will work in a similar way.

A Microsoft SQL Server database
In SQL Server you can create a database table as follows.
Connect to the database.
Execute an SQL Select query to retrieve relevant records.
In our case we just check for temperatures higher than 80 degrees within the last ten minutes.
SELECT [MachineName], MAX(Temperature) FROM [dbo].[MachineData] WHERE Timestamp > DATEADD(MINUTE, -10, SYSDATETIME()) AND Temperature > 80 GROUP BY [MachineName];
You can adapt the query to fit your needs. You can also to some more sophisticated operations here like the average, maximum, number of occurrences or process data from multiple tables as well.
Send the Alert using SIGNL4.
If the above SQL query retrieved some records it means we have a situation worth communicating. In our script we use the SIGNL4 webhook to send the data to SIGNL4.
Of course, we would like to check the database in regular intervals. In Windows the easiest way to do so is to use the Windows Task Scheduler. Here you can create a new task, let it run every ten minutes and let it execute the respective script.
Now you can test your script manually first. Add some sample date into the database table that should trigger an alert. If all runs find you will receive the alert in your SIGNL4 app.
SIGNL4 can further increase the visibility of alerts through its Signals and Services section. Augmenting the color and icon of alerts will provide more relevant information at a glance without having to open the alert.
