- alert_serialization_interval: The interval that should occur from a
serialization of a buffer of alerts on the history file and the next one
(default if not specified: 1 hour, as it is a quite expensive operation in terms
of resources if the system received many alerts)
- alert_bufsize: Size of the buffer containing the alerts to be sent, in group,
to the serializer thread. The buffer is sent when full and made empty even
when the alert_serialization_interval parameter is not expired yet, for
avoiding overflows, other memory problems or deadlocks (default value if
not specified: 30)
- alert_clustering_interval: The interval that should occur from the clustering
of the alerts in the log according to the provided clustering hierarchies and
the next one (default if not specified: 300 seconds)
