The service exposes DSL for specifying alarming rules over an HTTP.
Documentation of the DSL syntax for the rules can be found here.
Make sure to start Cassandra first. From the project's root execute following command:
docker-compose -f docker-compose.yml up
In order to service successfully start, create keyspace in Cassandra named as exported environment variable RULES_ENGINE_DB_KEYSPACE
(default "rules_engine"):
docker exec -it mainflux-rules-engine-cassandra cqlsh -e "CREATE KEYSPACE IF NOT EXISTS rules_engine WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 1 };"
Execute command to run service:
go run cmd/main.go
It runs service on 127.0.0.1:9000
by default, or on port exported in PORT
environment variable.
To verify setup, go to the browser and check 127.0.0.1:9000/health
URL.
