Building#

The DevNullReceiver satellite has no additional dependencies. The satellite is not build by default, building can be enabled via:

meson configure build -Dsatellite_dev_null_receiver=true

None

This satellite inherits the following framework parameters from its base classes:

Parameter	Type	Description	Default Value
`_allow_overwriting`	Bool	Switch whether overwriting files is allowed or not. If set to `false` and a file exists already, this satellite will go into `ERROR` state.	`false`
`_data_transmitters`	List of strings	List of canonical names of transmitter satellites this receiver should connect to and receive data messages from.	-
`_eor_timeout`	Unsigned integer	Timeout waiting for the reception of the end-of-run message. The receiver satellite will wait this number of seconds for receiving the EOR message from each connected transmitter satellite, and will go into error state if the message has not been received within this period. The timeout will only be started after the pending data messages have been read from the queue.	`10`

Parameter	Type	Description	Default Value
`_allow_departure`	Bool	If `true`, regular departures of satellites will not cause an interrupt to SAFE mode	`true`
`_heartbeat_interval`	Unsigned integer	Interval in seconds between heartbeats to be sent to other Constellation components	`10`

This satellite inherits the following framework metrics from its base classes:

Metric	Description	Value Type	Metric Type	Interval
`BYTES_RECEIVED`	Amount of bytes received from all transmitters	Integer	`LAST_VALUE`	10s
`DISKSPACE_FREE`	Amount of megabytes available on the file system the current output file is located	Integer	`LAST_VALUE`	10s
