Event Manager_

Event Manager is used to collect different events (like ATTRIBUTE_CHANGED, OBJECT_ADDED etc) from different sources and store them in one place.

Overview

• The monitoring of changed statuses will be implemented to the code

• Event manager reflects statuses of different objects

• In case status was changed the information is sent to EventDB to be stored

• This method does not guarantee the fact of storing data in EventDB

• At the moment only statuses are monitored. Other events can be added in future, but they are not in a scope today.

• This manager is used by MIS.

• Context is not used to obtain data from DB.

• Only changed statuses should be stored to EventDB, not new.\

• events are transferred to event manager via Kafka

Obtain data from EventDB

Get list

GET https://dev.ehealth.world/api/events

Input parameters (optional)

• date

• event_type

• entity_type

• attribute_name

• attribute_name & new_value

• page

• page_size

Period of events provided in the response of method cannot exceed value of EVENTS_LIST_MAX_PERIOD_HOURS variable (if variable is not specified, the default value is 1 hour) specified in configuration of Event Manager

1. if date and date_to parameters are set, the following condition must be met: date - date_to <= EVENTS_LIST_MAX_PERIOD_HOURS

   1. in case of error return 422 ("Period must be less than or equal to {period} hours. Please set allowed period to the query")

2. if date and date_to parameters are not set, use date_to as now() and the following condition must be met: date - date_to = EVENTS_LIST_MAX_PERIOD_HOURS

3. if date_to parameter is set and date is not set, the following condition must be met: date - date_to = EVENTS_LIST_MAX_PERIOD_HOURS

4. if date parameter is set and date_to is not set, the following condition must be met: date - date_to = EVENTS_LIST_MAX_PERIOD_HOURS

Logic WS

1. Verify the validity of access token

2. Check user scopes in order to perform this action (scope = 'event:read')

   1. return 403 in case invalid scope(s)

Validate EventType

Each event type can be filtered by scopes. At the moment we have only one event - StatusChangeEvent

1. Check user scopes in order to perform this action (scope = 'event:read')

   1. return 403 in case invalid scope(s)

Get by ID

GET https://uaehealthapi.docs.apiary.io/reference/public.-event-manager/get-events-by-id/get-events-by-id

Input parameters

• id

Logic WS

1. Verify the validity of access token

2. Check user scopes in order to perform this action (scope = 'event:read')

   1. return 403 in case invalid scope(s)

Event termination

Event termination starts with cron sqedule filtered by

• time (event_max_time)

• amount of data (event_max_number)

All filteres are parametrized. By default event_max_time=month, event_max_number=50.000

Cron starts once in 24H and delete data if events.id > "amount of data" OR events.event_time > "time"
