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
logentries	object_id	bigint	NULL	FK: objects table (service associated with column)
hosts	check_service_object_id	bigint	NULL	FK: objects table (service associated with column)

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 and shows log attributes
statehist	hosts, services	parses compatlog 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 <<EOF
GET servicegroups

EOF

(cat servicegroups; sleep 1) | netcat 127.0.0.1 6558

Livestatus COMMAND Queries

$ echo -e 'COMMAND <externalcommandstring>' | 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 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.
