Tools and Platform

Icinga Quality, Testing and Community Support

website and open source ticketing system

Icinga- API

based on PHP

Icinga-Core

C based source MySQL

PostgreSQL Oracle

Icinga-Web

based on PHP using Sencha,

Agavi MVC

Icinga-Doc

based on Docbook in english and

german

GIT GIT GIT GIT

Icinga-Reports

based on Jasper -

Reporting

Single node architecture - today

IDO

• MySQL • PostgreSQL

• Oracle

Multi node architecture - today

Personally

Database performance

�  serial database-write-performance slower

•  YES ~ 5% slower

�  serial database-read-performance slower

•  YES ~ 15% slower

�  random database-read-performance slower

•  NO ~ 900% faster

Database stability

�  Database stable ?

•  YES

�  Knowledge needed ?

•  YES

MySQL Tips

�  use InnoDB

�  use MySQL 5.5

•  Performance

•  atomic Operations

•  InnoDB-Background-Threads

�  disable query cache

�  innodb_flush_log_at_trx_commit = 0

NEB disadvantages

�  NEB-Development is limited to C/C++ Coders

�  it is not possible to change a NEB at runtime

�  NEB’s must reside on the same server

�  in the worst-case scenario a NEB could crash the Icinga process

�  changes to the Icinga-Core can break a NEB

Future architecture

Icinga-Core

• MySQL

• PostgreSQL • Oracle

Icinga-Web

ExtJS / Agavi

CORE-API

Icinga-API

Icinga-Web and DB-API

ExtJS / Agavi

Future architecture – Core API

Icinga-Core

CORE-API

�  XML - RPC •  XML based remote procedure call

•  firewall awareness

•  de facto standard

�  bidirectional connection initiation

�  checkresult reaper replacement

HTTP Interface

�  request almost all Icinga database fields that are supported by Icinga-API (which covers almost all fields)

�  filter via nested AND and OR groups (Condition 1 AND (Condition 2 OR (Condition 3 AND Condition 4))..etc.)

�  add Order, Limit, Group By

�  get data via XML or JSON

�  sending commands via PUT

HTTP Interface - Example

!http://localhost/icinga-web/web/api/service/filter[AND(HOST_CURRENT_STATE|=|0;OR(SERVICE_CURRENT_STATE|=|1;SERVICE_CURRENT_STATE|=|2))]/ columns(SERVICE_NAME|HOST_NAME|SERVICE_CURRENT_STATE|HOST_NAME|HOST_CURRENT_STATE|HOSTGROUP_NAME)/order(SERVICE_CURRENT_STATE;DESC)/countColumn=SERVICE_ID/authkey=APITEST123456/xml!

<results>! <result>!

<column name="SERVICE_ID">295</column>! <column name="SERVICE_OBJECT_ID">139</column>!

<column name="SERVICE_IS_ACTIVE">1</column>! <column name="SERVICE_INSTANCE_ID">1</column>! <column name="SERVICE_NAME">MailQ</column>!

<column name="SERVICE_DISPLAY_NAME">MailQ</column>! <column name="SERVICE_OUTPUT">Error occured:error=1:0:0</column>! <column name="SERVICE_PERFDATA"></column>!

</result>! <result>!

<column name="SERVICE_ID">311</column>! <column name="SERVICE_OBJECT_ID">155</column>! <column name="SERVICE_IS_ACTIVE">1</column>!

<column name="SERVICE_INSTANCE_ID">1</column>! <column name="SERVICE_NAME">POP3</column>!

<column name="SERVICE_DISPLAY_NAME">POP3</column>! <column name="SERVICE_OUTPUT">Verbindungsaufbau abgelehnt</column>! <column name="SERVICE_PERFDATA"></column>!

</result>! <total>2</total>!
