# 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.
Additional global custom variables populated from 'Vars' constant (object_id is NULL).
### Livestatus
#### Livestatus Tables
Table | Join |Description
--------------|-----------|----------------------------
hosts | | host config and status attributes, services counter
hostgroups | | hostgroup config, status attributes and host/service counters
services | hosts | service config and status attributes
servicegroups | | servicegroup config, status attributes and service counters
contacts | | contact config and status attributes
contactgroups | | contact config, members
commands | | command name and line
status | | programstatus, config and stats
comments | services | status attributes
downtimes | services | status attributes
timeperiods | | name and is inside flag
endpoints | | config and status attributes
log | services, hosts, contacts, commands | parses [compatlog](#objecttype-compatlogger) and shows log attributes
statehist | hosts, services | parses [compatlog](#objecttype-compatlogger) and aggregates state change attributes
The `commands` table is populated with `CheckCommand`, `EventCommand` and `NotificationCommand` objects.
#### Livestatus Table Attributes
A detailed list which table attributes are supported can be found here: [https://wiki.icinga.org/display/icinga2/Livestatus#Livestatus-Attributes]
#### Livestatus GET Queries
$ echo -e 'GET services' | netcat 127.0.0.1 6558
$ cat servicegroups < Livestatus COMMAND Queries
A list of available external commands and their parameters can be found [here](#external-commands-list-detail)
$ echo -e 'COMMAND ' | netcat 127.0.0.1 6558
#### Livestatus Filters
and, or, negate
Operator | Negate | Description
----------|------------------------
= | != | Euqality
~ | !~ | Regex match
=~ | !=~ | Euqality ignoring case
~~ | !~~ | Regex ignoring case
> | | Less than
< | | Greater than
>= | | Less than or equal
<= | | Greater than or equal
#### Livestatus Stats
Schema: "Stats: aggregatefunction aggregateattribute"
Aggregate Function | Description
-------------------|--------------
sum |
min |
max |
avg | sum / count
std | standard deviation
suminv | sum (1 / value)
avginv | suminv / count
count | ordinary default for any stats query if not aggregate function defined
Example:
GET hosts
Filter: has_been_checked = 1
Filter: check_type = 0
Stats: sum execution_time
Stats: sum latency
Stats: sum percent_state_change
Stats: min execution_time
Stats: min latency
Stats: min percent_state_change
Stats: max execution_time
Stats: max latency
Stats: max percent_state_change
OutputFormat: json
ResponseHeader: fixed16
#### Livestatus Output
* CSV
CSV Output uses two levels of array seperators: The members array separator
is a comma (1st level) while extra info and host|service relation separator
is a pipe (2nd level).
Seperators can be set using ASCII codes like:
Separators: 10 59 44 124
* JSON
Default separators.
#### Livestatus Error Codes
Code | Description
----------|--------------
200 | OK
404 | Table does not exist
452 | Exception on query
#### Livestatus Schema Extensions
Icinga 2 specific extensions are shown below:
New table: `endpoints`
Table | Column
----------|--------------
endpoints | name
endpoints | identity
endpoints | node
endpoints | is_connected
New columns:
Table | Column
----------|--------------
hosts | is_reachable
services | is_reachable
hosts | check_source
services | check_source
downtimes | triggers
downtimes | trigger_time
commands | custom_variable_names
commands | custom_variable_values
commands | custom_variables
commands | modified_attributes
commands | modified_attributes_list
status | custom_variable_names
status | custom_variable_values
status | custom_variables
Command custom variables reflect the local 'vars' dictionary.
Status custom variables reflect the global 'Vars' constant.
