1. There is a bug with EPA derived event saving, sometimes we get different
settings after reloading the page - I noticed that while creating multiple
derived events inside one EPA.
2. I have the following definition for EPA:
{
"name": "Treatment",
"createdDate": "Thu Sep 10 2015",
"epaType": "Basic",
"context": "TContext",
"inputEvents": [
{
"name": "OsmatranjeContextUpdate",
"alias": "osmatranje",
"consumptionPolicy": "Consume",
"instanceSelectionPolicy": "First"
}
],
"computedVariables": [],
"evaluationPolicy": "Immediate",
"cardinalityPolicy": "Single",
"internalSegmentation": [],
"derivedEvents": [
{
"name": "TreatmentAlert",
"condition": "osmatranje.stetocina_id = 22 or
osmatranje.stetocina_id = 29 or osmatranje.stetocina_id = 30 or
osmatranje.stetocina_id = 36",
"reportParticipants": false,
"expressions":
{
"Duration": "0",
"mesto_id": "osmatranje.mesto_id",
"stetocina_id": "osmatranje.stetocina_id",
"level": "if osmatranje.vrednost > 100 then 2
else 0 endif",
"entityId": "osmatranje.mesto_id ++ \"-\" ++
osmatranje.stetocina_id",
"entityType": "\"TreatmentAlert\""
}
},
{
"name": "TreatmentAlert",
"condition": "osmatranje.stetocina_id = 13",
"reportParticipants": false,
"expressions":
{
"Duration": "0",
"mesto_id": "osmatranje.mesto_id",
"stetocina_id": "osmatranje.stetocina_id",
"level": "if (osmatranje.vrednost >=5 and
osmatranje.vrednost <=8) then 1 elseif osmatranje.vrednost > 8 then 2 else 0
endif",
"entityId": "osmatranje.mesto_id ++ \"-\" ++
osmatranje.stetocina_id",
"entityType": "\"TreatmentAlert\""
}
}
],
"derivedActions": []
}
],
The rule for "level" calculation depends on "stetocina_id".
If I send the request:
{"Name" : "OsmatranjeContextUpdate", "stetocina_id" : "36", "mesto_id" :
"20034", "vrednost" : "6"}
I expect to use the 1st rule, and "level" should be 0, but it uses the 2nd
rule and I get 1.
We are using the CEP VM from from FIWARE cloud, we can provide its public IP
address if necessary. The CEP is connected with Orion which has also a public
IP, it is possible to query the alert in Orion.
Best regards,
Janos
