* Add support for YAML strategyMagnus Kühne3 days1-0/+9
| | | | | | | | | | | | | Introduces a new 'yaml' strategy using Ansible's `from_yaml` to read target files. This allows users to group multiple targets with distinct label sets (e.g., severity or job) within a single file, optimizing Prometheus file-based service discovery. - Refactored task structure into `strategy_*.yml` for consistency. - Extracted shared exporter variable computation. - Implemented label merging where exporter labels override defaults. - Included support for groups and hosts without labels to prevent crashes.

* Add run_once option for handlersColin Wilk2023-10-111-0/+12
| | | | | | | | | | | | | | This adds the run_once option for the two handler types (shell and command). The variables `prometheus_target_handler_command_run_once` and `prometheus_target_handler_shell_run_once` are introduced to control this behavior. For this change a switch from the Ansible Handlers to regular tasks was necessary to enforce run_once behavior with delegated hosts. If you don't rely on handler specific features such as deferring, nothing changes when using the role. Signed-off-by: Colin Wilk <colin.wilk@tum.de>
* Add ability to specify target path prefixColin Wilk2023-06-111-2/+13
| | | | | | | | This will decrease the amount of redundant configuration for users by allowing them to specify a general prefix on global / exporter / play level Signed-off-by: Colin Wilk <colin.wilk@tum.de>

* Switch to 4 space indentation by default for lineinfile strategyColin Wilk2023-05-291-1/+1
| | | | | | | | | | | | | | | | | | This will change indentation in target files like: - labels: exporter: node targets: - host:9100 to - labels: exporter: node targets: - host:9100 Signed-off-by: Colin Wilk <colin.wilk@tum.de>

* Switch to single host per exporter configurationColin Wilk2023-05-271-2/+4
| | | | | | | | | | | | | | | | | Before you could do multiple hosts per exporter like this: - id: node_exporter hosts: - host1 - host2 This was removed since it simplifies the code quite a bit and you can still archive the same behavior like this: - { id: node_exporter, host: host1 } - { id: node_exporter, host: host2 } Signed-off-by: Colin Wilk <colin.wilk@tum.de>
* Move hook ansible module config into their own config objectColin Wilk2023-05-261-17/+18
| | | | | | | | | | | | Keep * prometheus_target_handler_command_enabled * prometheus_target_handler_command_become * prometheus_target_handler_shell_enabled * prometheus_target_handler_shell_become to avoid being overwritten when specifying prometheus_target_handler_command or prometheus_target_handler_shell Signed-off-by: Colin Wilk <colin.wilk@tum.de>
