Mattermost Satellite

Name	Mattermost
Description	Satellite sending log messages to Mattermost
Category	Monitoring
Language	C++

Description

This satellite listens to log messages sent by other satellites and sends them to a Mattermost channel. The name of the sender will be used as username in Mattermost. Log messages with a log level of WARNING are marked as important and log messages with a log level of CRITICAL are marked as urgent. In both cases the log messages are prefixed with @channel to notify all users in the channel. In addition to logging from other satellites, messages are sent when a run is started, stopped or interrupted.

Building

The Mattermost requires cpr, which is downloaded on demand. The satellite is not build by default, building can be enabled via:

meson configure build -Dsatellite_mattermost=true

Parameters

Parameter	Description	Type	Default Value
webhook_url	URL of the Mattermost webhook	string	-
log_level	Minimum log level of the logger	string	WARNING
ignore_topics	Ignore log messages with certain topics	list of strings	[FSM]
only_in_run	Only log to Mattermost in the RUN, interrupting or SAFE state	bool	false

Framework Parameters

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

Parameters inherited from Satellite

Autonomous Operation

Parameter	Type	Description	Default Value
_max_heartbeat_interval	Unsigned integer	Maximum interval in seconds between heartbeats to be sent to other Constellation components. The time between heartbeat is adjusted automatically according to the number of nodes in the Constellation but will never exceed this value.	30
_role	Role name	Role this satellite should take in the Constellation. Accepted values are ESSENTIAL, DYNAMIC, TRANSIENT and NONE.	DYNAMIC

Transition Orchestration

Parameters to control autonomous transition orchestration of satellites:

Parameter	Type	Description	Default Value
_conditional_transition_timeout	Unsigned integer	Timeout in seconds to wait for all conditions to be satisfied for conditional transitioning	30
_require_initializing_after	List of strings	List of canonical names of remote satellites for conditional transitioning in initializing state	-
_require_launching_after	List of strings	List of canonical names of remote satellites for conditional transitioning in launching state	-
_require_landing_after	List of strings	List of canonical names of remote satellites for conditional transitioning in landing state	-
_require_starting_after	List of strings	List of canonical names of remote satellites for conditional transitioning in starting state	-
_require_stopping_after	List of strings	List of canonical names of remote satellites for conditional transitioning in stopping state	-
