SNMP transport parameters

Spring common parameters

ParameterEnvironment VariableDefault ValueDescription
spring.main.web-environment WEB_APPLICATION_ENABLE false If you enabled process metrics you should also enable 'web-environment'.
spring.main.web-application-type WEB_APPLICATION_TYPE none If you enabled process metrics you should set 'web-application-type' to 'servlet' value.
spring.main.allow-circular-references "true" Spring Boot configuration property that controls whether circular dependencies between beans are allowed.

Server common parameters

ParameterEnvironment VariableDefault ValueDescription
server.address HTTP_BIND_ADDRESS Server bind address (has no effect if web-environment is disabled).
server.port HTTP_BIND_PORT 8083 Server bind port (has no effect if web-environment is disabled).

Zookeeper connection parameters. Used for service discovery.

ParameterEnvironment VariableDefault ValueDescription
zk.enabled ZOOKEEPER_ENABLED false Enable/disable zookeeper discovery service.
zk.url ZOOKEEPER_URL localhost:2181 Zookeeper connect string
zk.retry_interval_ms ZOOKEEPER_RETRY_INTERVAL_MS 3000 Zookeeper retry interval in milliseconds
zk.connection_timeout_ms ZOOKEEPER_CONNECTION_TIMEOUT_MS 3000 Zookeeper connection timeout in milliseconds
zk.session_timeout_ms ZOOKEEPER_SESSION_TIMEOUT_MS 3000 Zookeeper session timeout in milliseconds
zk.zk_dir ZOOKEEPER_NODES_DIR /thingsboard Name of the directory in zookeeper 'filesystem'
zk.recalculate_delay ZOOKEEPER_RECALCULATE_DELAY_MS 0 The recalculate_delay property is recommended in a microservices architecture setup for rule-engine services. This property provides a pause to ensure that when a rule-engine service is restarted, other nodes don't immediately attempt to recalculate their partitions. The delay is recommended because the initialization of rule chain actors is time-consuming. Avoiding unnecessary recalculations during a restart can enhance system performance and stability.

Snmp server parameters

ParameterEnvironment VariableDefault ValueDescription

transport.sessions.inactivity_timeout TB_TRANSPORT_SESSIONS_INACTIVITY_TIMEOUT 600000 Session inactivity timeout is a global configuration parameter that defines how long the device transport session will be opened after the last message arrives from the device. The parameter value is in milliseconds. The last activity time of the device session is updated if the device sends any message, including keepalive messages If there is no activity, the session will be closed, and all subscriptions will be deleted. We recommend this parameter to be in sync with device inactivity timeout ("state.defaultInactivityTimeoutInSec" or DEFAULT_INACTIVITY_TIMEOUT) parameter which is responsible for detection of the device connectivity status in the core service of the platform. 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.
