Alerts on bridge offline status

To ensure the sensor data is continuously sent to the software, it’s essential that the bridges remain online. You can set up an alert to notify you when a bridge goes offline.

We use a proxy to monitor bridge status: if the bridge is sending data from sensors to our platform, it is considered online; if not, it’s considered offline. Our pulse counters (used for gas, water and OEE) send a heartbeat every hour. However, our electricity sensors do not send a heartbeat, so if an asset is turned off, no data is sent from the bridge to our platform.

To set up a bridge alert, follow these steps:

1. Navigate to the ‘Alerts’ menu from the header bar
2. Go to the ‘Configuration’ tab
3. Hit the ‘Create new alert’ button to open the dialog to configure the rules of the alert
4. In the ‘Select product’ field, choose the ‘Bridge’ option. The ‘Bridge offline status alert’ will be selected automatically.
5. Setup the alert trigger conditions:
   1. Select the bridge(s) you want to setup the alert for
   2. Define for how long the condition must be met before the alert is triggered
   3. Add a message you want to show when the alert gets triggered
   4. Add a minimum time interval between the alerts, to prevent excessive alerts 
   5. Select whether you want to enable them always, or configure a specific schedule for when the alert should be triggered, for example only within your production hours.
   6. Add the recipient(s) of the alert. This can either be an email or a text message in WhatsApp.
6. Hit ‘Save’ to save the alert configuration.

Recommendations & Tips:

• Visit your Status page to verify which sensors are connected to each bridge.
• To avoid false alerts (false negatives) for electricity sensors: Do not set up alerts for bridges receiving data from sensors on machines while they are turned off. In such cases, the bridge is not sending data to the Sensorfact platform, leading to false alerts.
• Bridge alerts are not available for Compressed Air and Predictive Maintenance.
• If a bridge goes offline, it does not necessarily mean that data is lost. In most cases, it simply results in a delay in sending data to the platform. Once the bridge comes back online, it will transmit the stored data. The bridge can retain data for about up to a month.
