Device state parameters
| Parameter | Environment Variable | Default Value | Description |
| state.defaultInactivityTimeoutInSec | DEFAULT_INACTIVITY_TIMEOUT | 600 | Device inactivity timeout is a global configuration parameter that defines when the device will be marked as "inactive" by the server. The parameter value is in seconds. A user can overwrite this parameter for an individual device by setting the “inactivityTimeout” server-side attribute (NOTE: expects value in milliseconds). We recommend this parameter to be in sync with session inactivity timeout ("transport.sessions.inactivity_timeout" or TB_TRANSPORT_SESSIONS_INACTIVITY_TIMEOUT) parameter which is responsible for detection of the stale device connection sessions. The value of the session inactivity timeout parameter should be greater or equal to the device inactivity timeout. Note that the session inactivity timeout is set in milliseconds while device inactivity timeout is in seconds. |
| state.defaultStateCheckIntervalInSec | DEFAULT_STATE_CHECK_INTERVAL | 60 | Interval for checking the device state after a specified period. Time in seconds |
| state.persistToTelemetry | PERSIST_STATE_TO_TELEMETRY | false | Controls whether we store the device 'active' flag in attributes (default) or telemetry. If you decide to change this parameter, you should re-create the device info view as one of the following: If 'persistToTelemetry' is changed from 'false' to 'true': 'CREATE OR REPLACE VIEW device_info_view AS SELECT * FROM device_info_active_ts_view;' If 'persistToTelemetry' is changed from 'true' to 'false': 'CREATE OR REPLACE VIEW device_info_view AS SELECT * FROM device_info_active_attribute_view;' |
| state.telemetryTtl | STATE_TELEMETRY_TTL | 0 | Millisecond value defining time-to-live for device state telemetry data (e.g. 'active', 'lastActivityTime'). Used only when state.persistToTelemetry is set to 'true' and Cassandra is used for timeseries data. 0 means time-to-live mechanism is disabled. |
| state.rule.node.deviceState.rateLimit | DEVICE_STATE_NODE_RATE_LIMIT_CONFIGURATION | 1:1,30:60,60:3600 | Defines the rate at which device connectivity events can be triggered. Comma-separated list of capacity:duration pairs that define bandwidth capacity and refill duration for token bucket rate limit algorithm. Refill is set to be greedy.
