Device Failure Notifications

One of Signomix’s features is the detection of interruptions in the operation of data sources or devices.

The service reports situations as problems when a given data source stops sending data messages.

The mechanism for detecting such issues takes into account data sources that:

• are marked as active,
• have a data transmission interval greater than zero specified in their configuration,
  Situations where a device misses at least two consecutive transmissions are reported as a problem.

How It Works

Problem detection runs periodically at a frequency that depends on the user’s account type:

• every 20 minutes for free accounts
• every 10 minutes for paid accounts

The different frequencies of problem detection and transmission intervals assigned to the device mean that the time elapsing from the moment a device failure occurs until the problem is reported to the user will vary depending on the account type.

For free accounts:

• 20 to 40 minutes -> if the device transmits data more frequently than every 20 minutes
• 2 * transmission interval + up to 20 minutes -> if the device transmits data less frequently than every 20 minutes

For paid accounts:

• 10 to 20 minutes -> if the device transmits data more frequently than every 10 minutes
• 2 * transmission interval + up to 10 minutes -> if the device transmits data less frequently than every 10 minutes

How users are notified

Detected issues are reported to users:

• to the device owner (the user who registered it),
• to a member of the field team (listed in the device configuration team field),
• device administrators (listed in the device configuration administrators field).

The history of device malfunctions is available to the user after logging into the web application under the Infrastructure > Notifications menu.

Notifications can also be sent via email, SMS, or to an external service (webhook).
