Quality


#FLOSSUK

Continous Integration

• Jenkins Server – build.icinga.org


#FLOSSUK

Operating System Support

• Global package repository – packages.icinga.org• Snapshot and release builds• Builds for major platforms

– RHEL– SLES– Fedora– OpenSuse– Debian

• Supplement (not replacement) for official repos like RepoForge or Debian Backports


#FLOSSUK

Documentation

• We had DocBook


#FLOSSUK

Documentation – Future

• DocBook Pros– You can generate hundreds of different formats out of

one Docbook • DocBook Cons

– We didn’t!– Updating DocBook files is time-consuming and

complicated– It sucks!

• Switch from DocBook to Markdown• Icinga 2 doc is available in Markdown from day one• We‘ll migrate the 1.x documentation to Markdown


#FLOSSUK

Documentation – Markdown

• How it will look like### Installation Paths

By default Icinga 2 uses the following files and directories:

Path | Description ------------------------|------------------------------------ /etc/icinga2 | Contains Icinga 2 configuration files. /etc/init.d/icinga2 | The Icinga 2 init script. /usr/share/doc/icinga2 | Documentation files that come with Icinga 2. /usr/share/icinga2/itl | The Icinga Template Library. /var/run/icinga2 | PID file.

ICINGA 2


Icinga 2 - Overview

• Based on C++ and Boost– Supports all major *NIX and Windows platforms

• Different config format– there is a conversion script!

• Included cluster stack• Functions by component• icinga2-disable-feature / icinga2-enable-feature• Components can run anywhere in a cluster• MySQL, PostgreSQL and Livestatus support included• Packages and Vagrant Box available now!

#FLOSSUK


Icinga 2 – Components

• Checker• Cluster• Compat

– Command Pipe– Compat Log– Status.dat

• Livestatus• Perfdata• Notification• ido_mysql• ido_postgresql

#FLOSSUK


Icinga 2 – Major config differences

• There is no host check -> Use the check attribute• Global macros• Contact and Contactgroup -> User and UserGroup

– no notification-specific attributes for services -> Notification Object

• Freely definable macros for commands define command { command_name ping4 command_line $USER1$/check_ping -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -p 5}

define service { use local-service host_name localhost service_description PING check_command ping4!100.0,20%!500.0,60%}

object CheckCommand "ping4" { command = "$plugindir$/check_ping -H $HOSTADDRESS$ -w $wrta$,$wpl%$ -c $crta$,$cpl%$", macros = { wrta = 100, wpl = 20, crta = 500, cpl = 60 }}

object Host ”localhost" { services[“PING“] = { check_command = “ping4”, //macros[“wrta”] = 250 }}

#FLOSSUK


Icinga 2 – Major config differences

• New notification object– Icinga 1

– Icinga 2

• No fixed macro for IP address(es)• Escalations act as notification with defined begin and end

#FLOSSUK

service -> (contact, contactgroup) -> notification command

notification_options w,u,c,r,f,s

service -> notification -> notificationCommand -> user, userGroup

notification_state_filter = (StateFilterWarning | StateFilterUnknown | StateFilterCritical),notification_type_filter = (NotificationProblem | NotificationRecovery | NotificationFlappingStart | NotificationFlappingEnd | NotificationDowntimeStart | NotificationDowntimeEnd | NotificationDowntimeRemoved)

start = notification start + (notification_interval * first_notification)end = notification start + (notification_interval * last_notification)


#FLOSSUK

Icinga 2 – Cluster

• Cluster-based communication using SSL• Bidirectional connections supported• Domain support for logic splits in the configuration• Hash-based load distribution• “binlog” like retention for monitoring events and messages• Distributed components throughout the cluster

Icinga 2 – What’s next

• Apply– apply template Service ”flossuk-ping" to Host where host !=

"localhost”– apply template Service "flossuk-ping" to Host where "linux-

server" in hostgroups– apply template Service "flossuk-ping" to Host where "linux-

server" in hostgroups || host in [ "localhost" ] apply template Service "flossuk-ping" to Host where "linux-server" in hostgroups && host in [ "localhost2" ]

– apply template Service ”flossuk-ping" to Host where regex("e", host)

• Works with constants and variables• Match and Regex-Support

#FLOSSUK


Icinga 2 – What’s next

• Business Process Integration– Coming later this year– Basic user story in dev-tracker– Rule based configuration– Nested business project objects– Different levels and priorities– Expression/Wildcard/RegExp

• Puppet Modules• More Documentation• See Roadmap!

Icinga Web 2

Different Interfaces for Icinga

#FLOSSUK

Icinga WebIcinga Classic Icinga Mobile

Thruk, …


#FLOSSUK

Why another Interface

• We want a solution for all platforms– Simple and lightweight– Responsive for desktop, tablet, phone

• Icinga-Classic doesn’t fit enterprise needs• Icinga-Web is hard to extend• CLI-Support for cronjobs, plugins and shell• Support for multiple backends

• All existing versions will be in active maintenance!


#FLOSSUK

Icinga Web 2

• Lightweight like Icinga classic and flexible like Icinga Web• Easy to extend and embed into other projects• Support for multiple backends

– Status.dat– Database– Livestatus

• Supports multiple backends simultaneously, as failover backend

• Supports Icinga 1.x and Icinga 2.x• Responsive actions• FAST!
