# Appendix ## Schemas By convention `CheckCommand`, `EventCommand` and `NotificationCommand` objects are exported using a prefix. This is mandatory for unique objects in the command tables. Object | Prefix ------------------------|------------------------ CheckCommand | check_ EventCommand | event_ NotificationCommand | notification_ ### Status Files Status files used by Icinga 1.x Classic UI: `status.dat`, `objects.cache`. Icinga 2 specific extensions: * host and service objects support 'check_source' (added in Classic UI 1.10.0) * command objects support custom variables (added in Classic UI 1.11.2) * host and service objects support 'is_reachable' (added in Classic UI 1.11.3) ### DB IDO There is a detailed documentation for the Icinga IDOUtils 1.x database schema available on [http://docs.icinga.org/latest/en/db_model.html] #### DB IDO Schema Extensions Icinga 2 specific extensions are shown below: New tables: `endpoints`, `endpointstatus` Table | Column | Type | Default | Description --------------------|--------------------|----------|---------|------------- endpoints | endpoint_object_id | bigint | NULL | FK: objects table endpoints | identity | TEXT | NULL | endpoint name endpoints | node | TEXT | NULL | local node name Table | Column | Type | Default | Description --------------------|--------------------|----------|---------|------------- endpointstatus | endpoint_object_id | bigint | NULL | FK: objects table endpointstatus | identity | TEXT | NULL | endpoint name endpointstatus | node | TEXT | NULL | local node name endpointstatus | is_connected | smallint | 0 | update on endpoint connect/disconnect New columns: Table | Column | Type | Default | Description --------------------|-------------------------|----------|---------|------------- all status/history | endpoint_object_id | bigint | NULL | FK: objects table servicestatus | check_source | TEXT | NULL | node name where check was executed hoststatus | check_source | TEXT | NULL | node name where check was executed statehistory | check_source | TEXT | NULL | node name where check was executed servicestatus | is_reachable | integer | NULL | object reachability hoststatus | is_reachable | integer | NULL | object reachability logentries | object_id | bigint | NULL | FK: objects table (service associated with column) {host,service}group | notes | TEXT | NULL | - {host,service}group | notes_url | TEXT | NULL | - {host,service}group | action_url | TEXT | NULL | - Additional command custom variables populated from 'vars' dictionary.
