---

Our development cycles now last ~3 weeks, where we work on a defined 
feature set whilst fixing bugs and improving overall performance. This 
time, the new release comes with changes that may render previous 
configuration and state files invalid – please check the Changelog for 
details.

0.0.6 adds a new major feature to Icinga 2: Built-in ScheduledDowntime 
configuration objects can be used to set up recurring downtimes for 
services.

Imagine the following scenario: Your host will use a load service to 
check its performance at a regular interval. At night during backup, an 
increase in load may induce warning/critical check results and trigger 
alert notifications. While you can still schedule one downtime manually 
in advance or use external scripts and a cron job to schedule downtimes, 
it would be reasonable to plan your maintenance for a defined time range 
using a scheduled downtime.

Define a ScheduledDowntime template and set the time ranges, the author 
and the auto-generated comment:

template ScheduledDowntime "backup-downtime" {
   author = "icingaadmin",
   comment = "Scheduled downtime for backup",
   ranges = {
     monday = "02:00-03:00",
     tuesday = "02:00-03:00",
     wednesday = "02:00-03:00",
     thursday = "02:00-03:00",
     friday = "02:00-03:00",
     saturday = "02:00-03:00",
     sunday = "02:00-03:00"
   }
}

Add a new entry “backup” as scheduled_downtimes entry in the service 
definition and use the previously defined template. This works in the 
same way as notification declarations.

object Host "localhost" inherits "linux-server" {
   services["load"] = {
     templates = [ "generic-service" ],
     check_command = "load",
     scheduled_downtimes["backup"] = {
       templates = [ "backup-downtime" ]
     }
   }
}

Please note that only the first downtime is active within a given range 
and shown in the user interfaces.

Enjoy the new scheduled downtimes in Icinga 2! :-) Download Icinga 2 
0.0.6 and report any bugs to our development tracker and send us your 
test feedback in our community support channels or with a comment below.

CHANGE LOG

* Scheduled Downtimes as configuration object (also known as "Recurring 
Downtimes").
* Log command arguments
* Performance improvements for the config compiler
* Config validation provides stats at the end
* icinga2-enable-feature lists already enabled features
* Add support for latency statistics to IcingaCheckTask
* Implement support for using custom attributes as macros
* StatusDataWriter update interval as config attribute
* Improve performance with fetching data for status.dat/objects.cache, 
DB IDO and Livestatus
* Livestatus History Table performance improvements

Changes

* Generated object names (host with services array) use an exclamation 
mark instead of a colon
as seperator. State file objects with downtimes, comments, etc are 
invalid (unknown) for that
reason.
* Script variables are set using 'var' and 'const' instead of the 
previous 'set' identifier
* ITL constants are now embedded in libicinga
* Removed the ConsoleLogger object and keep the default console log 
enabled until we daemonize
