| ICINGA 2 CONVERSION SCRIPT FOR ICINGA 1.x CONFIGURATION | ||
| ======================================================= | ||
| Icinga 2 Migration Script | ||
| ========================= | ||
|
|
||
| This config conversion script provides support for basic Icinga 1.x | ||
| configuration format conversion to native Icinga 2.x configuration syntax. | ||
| In order to migrate existing configuration in Icinga 1.x format | ||
| the Icinga CLI as part of the Icinga Web 2 project will provide | ||
| a conversion module. | ||
|
|
||
| It won't just compile all objects and drop them at once, but keep your | ||
| existing 1.x template structure, only adding a new host->service link relation. | ||
| For work-in-progress details please check | ||
|
|
||
| The script will also detect the "attach service to hostgroup and put | ||
| hosts as members" trick from 1.x and convert that into Icinga2's template | ||
| system. | ||
| https://dev.icinga.org/issues/5821 | ||
| https://dev.icinga.org/issues/5929 | ||
|
|
||
| Furthermore the old "service with contacts and notification commands" logic | ||
| will be converted into Icinga2's logic with new notification objects, | ||
| allowing to define notifications directly on the service definition then. | ||
|
|
||
| Commands will be split by type (Check, Event, Notification) and relinked where | ||
| possible. The host's check_command is dropped, and a possible host check service | ||
| looked up, if possible. Otherwise a new service object will be added and linked. | ||
|
|
||
| Notifications will be built based on the service->contact relations, and | ||
| escalations will also be merged into notifications, having times begin/end as | ||
| additional attributes. Notification options will be converted into the new Icinga2 | ||
| logic. | ||
|
|
||
| Dependencies and Parents are resolved into host and service dependencies with | ||
| many objects tricks as well. | ||
|
|
||
| Timeperiods will be converted as is, because Icinga2's ITL provides the legacy-timeperiod | ||
| template which supports that format for compatibility reasons. | ||
|
|
||
| Custom attributes like custom variables, *_urls, etc will be collected into the | ||
| custom dictionary, while possible macros are automagically converted into the macro | ||
| dictionary (freely definable macros in Icinga 2.x). | ||
|
|
||
| All required templates will be inherited from Icinga2's Template Library (ITL). | ||
|
|
||
| Regular expressions are not supported, also for the reason that this is optional in Icinga 1.x | ||
|
|
||
| RUN | ||
| # mkdir /etc/icinga2/migration | ||
| # /usr/bin/icinga2-migrate-config -c /etc/icinga/icinga.cfg -o /etc/icinga2/migration/ | ||

| # /usr/bin/icinga2-migrate-config -v -c /etc/icinga/icinga.cfg -o /etc/icinga2/migration/ | ||
|
|
||
| TEST | ||
| Include /etc/icinga2/migration in /etc/icinga2/icinga2.conf and restart Icinga 2 | ||
|
|
||
| # vim /etc/icinga2/icinga2.conf | ||
|
|

| include "migration/*.conf" | ||

| REQUIREMENTS | ||
| - Perl: | ||
| Data::Dumper | ||
| File::Find | ||
| Storable qw(dclone) | ||
| Getopt::Long qw(:config no_ignore_case bundling) | ||
| Pod::Usage | ||
|
|
||
| - Icinga2 ITL | ||
|
|
||
|
|
||
| DEBUG | ||
| Compile Icinga2 with --enable-debug=yes and start it with -x. Alternatively, define the | ||
| ConsoleLogger Object and set severity to "debug". | ||
|
|
||
| object ConsoleLogger "my-debug-log" { | ||
| severity = "debug" | ||
| } | ||
|
|
||
|
|
||
| NOTES | ||
| - Excludes (will be ignored in member lists) | ||
| - Wildcards (* means all) | ||
| - additive + to += logic (only for the current object, does not work with users) | ||
| - Dependencies (host deps and parents are merged) | ||
| - Commands will be split into Check|Event|Notification Commands | ||
| - null (disable inheritance) only works non-converted values (not on contacts, commands, etc) being 0 | ||
| - notification_options string w,u,f is converted to | ||
| notification_{state,type}_filter = (StateFilterWarning | StateFilterUnknown | NotificationFilterFlapping) | ||
| - service escalations are converted into notifications with times = begin/end | ||
| begin = first_notification * notification_interval (now a time, not a counter) | ||
| - custom variables, *_url, *image*, notes, 2d_coords will be collected and stashed into the "custom" dictionary | ||
| similar to the macros dictionary. note: attributes starting with a number must be quoted. | ||
|
|
||
| TODO | ||
| - Dependency attributes: failure_criteria, inherits_parents, timeperiods | ||
| - Flapping Thresholds: old vs new logic | ||
| - some special object tricks, regex |
