What is NexAI Rule Engine?
Rule Engine is an easy to use framework for building event-based workflows. There are 3 main components:
- Message – any incoming event. It can be an incoming data from devices, device life-cycle event, REST API event, RPC request, etc.
- Rule Node – a function that is executed on an incoming message. There are many different Node types that can filter, transform or execute some action on incoming Message.
- Rule Chain – nodes are connected with each other with relations, so the outbound message from rule node is sent to next connected rule nodes.
Typical Use Cases
NexAI Rule Engine is a highly customizable framework for complex event processing. Here are some common use cases that one can configure via NexAI Rule Chains:
- Data validation and modification for incoming telemetry or attributes before saving to the database.
- Copy telemetry or attributes from devices to related assets so you can aggregate telemetry. For example data from multiple devices can be aggregated in related Asset.
- Create/Update/Clear alarms based on defined conditions.
- Trigger actions based on device life-cycle events. For example, create alerts if Device is Online/Offline.
- Load additional data required for processing. For example, load temperature threshold value for a device that is defined in Device’s Site or Tenant attribute.
- Trigger REST API calls to external systems.
- Send emails when complex event occurs and use attributes of other entities inside Email Template.
- Take into account User preferences during event processing.
- Make RPC calls based on defined condition.
- Integrate with external pipelines like Kafka, Spark, AWS services, etc.
