Stream connectors release notes

2026

October

New Stream connector

• Graphite Metrics - Initial release of Graphite Metrics.

Enhancement

• All stream connectors - Added triggers: with the new trigger_file parameter, you can run your own Lua code at specific points of a stream connector's lifecycle (initialization, event queuing, payload sending success or failure, storage operations) without editing the stream connector or the library. Your customizations are kept when the stream connector or the library is updated. For more technical information, see PR 389.
• Centreon library: sc_params - Added the drop_events_on_send_failure parameter (disabled by default). When enabled, if the stream connector cannot send data to the target tool, the events are dropped and the error is logged instead of being kept in Broker retention. For more technical information, see PR 388.
• Centreon library: sc_params - The values of parameters whose name contains token or secret are now hidden in the log file, in addition to those containing pass or key. For more technical information, see PR 380.

Bug fixes

• Centreon library: sc_event - Fixed an error that occurred when a downtime event was received for a host or service that was not present in the Broker cache. For more technical information, see PR 393.

August

Enhancement

• Splunk Metrics - Optimized the stream connector to avoid DOS.
• New OpenTelemetry otelhttp community stream connector for metrics, provided by a community contribution PR 290.
• Reduced unnecessary logging when Broker has no new messages to process.

Bug fixes

• Splunk Metrics - Fixed cases where the stream connector may not work with self signed certificates, based on a community contribution PR 311.
• Canopsis Events - Fixed crashes on host acknowledgement events.

July

Enhancement

• Clickhouse Metrics - Added a way for stream connectors to store data. For more technical information, see PR 205.
• Canopsis Events - Added bulk events. For more technical information, see PR 274.

Bug fixes

• Centreon library: sc_event - Fixed scheduled_downtime_depth value that could be above 1. Fixed an issue where events were never sent when a status change occurred during a downtime.
• InfluxDB 2 Metrics - Properly escape host names in tags.
• Centreon library: sc_params - Fixed incorrect usage of broker v2 API.
• Canopsis Events - Fixed downtime names/IDs that weren't unique. Fixed a library that wasn't properly detecting the status of a host/service in a downtime event.

New Stream connector

• Elastic Metrics - Initial release of Elastic Metrics.

February

Bug fixes

• Centreon library: sc_event - Fixed an issue occuring when checking if an event was monitored by an accepted poller.

January

Enhancement

• Centreon library: sc_logger - Allowed the possibility to log curl commands with a new method called log_curl_command.
• sc_event - Added a new log_curl_commands parameter to enable logging curl commands.
• Centreon library: sc_event - Handled event flapping with a new method (is_valid_event_flapping_state).
• Centreon library: sc_params - Added a new flapping parameter to filter flapping events.
• Centreon library: sc_flush - Added a new add_queue_metadata method to properly add metadata to a queue.

Bug fixes

• Centreon library: sc_event - The long output of the stream connector was incorrectly using the standard output, leading to loss of data.
• Centreon library: sc_event - Used the correct cache entry when checking the state of a service in a downtime event.
