The Java BACI properties (jbaci) implementation was done some time ago, but left some stuff without proper implementation. So far, only the implementation of archive_delta and archive_delta_percent were found to be left out.
Properties
| Name | Default | Description |
|---|---|---|
| min_timer_trig | 0.001 | Maximum sampling rate |
| default_timer_trig | 1.0 | Default monitoring sampling rate (Only monitors, doesn't affect archival) |
| archive_min_int | 0.0 | Minimum time between archiving events. 0 means disabled; it will be archived any time needed by delta or delta percent. |
| archive_max_int | 0.0 | Maximum time between archiving events. 0 means disabled; it will not be archived unless triggered by delta or delta percent. |
| min_delta_trig | 0 | false | Default monitoring on-change trigger (Only monitors, doesn't affect archival) |
| archive_delta | 0 | false | Value change that triggers an archiving event. 0 means disabled; it will not be archived unless triggered by time or delta percent change. |
| archive_delta_percent | 0.0 | Value percentage change that triggers an archiving event. 0 means disabled; it will not be archived unless triggered by time or delta change. |
Description
Archive Delta
This is a terminology describing the need to publish a new value the monitoring archival chain when the last monitored value has changed by more than an absolute value.
