Add support for YAML strategy

2026-02-09T16:23:57+00:00

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 handlers

2023-10-11T13:49:45+00:00

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.

Add ability to use exporter without id property

2023-06-15T20:52:07+00:00

The id property of the exporter is used for checking the default values
specified in `prometheus_target_exporter_defaults` variable.
However when both the `host` and the `path` fields are specified
manually in the `prometheus_target_exporter` list this id is never
looked up.
The way the templating was handled however, still resulted in an error
when leaving out the id field.
The templating code was now rewritten to allow for the following
exporter configuraion to run:

prometheus_target_exporter:
- { host: exporter_without_id, path: /opt/simple_target4.yml }

Add ability to specify target path prefix

2023-06-11T16:53:04+00:00

This will decrease the amount of redundant configuration for users by
allowing them to specify a general prefix on global / exporter / play
level

Switch to single host per exporter configuration

2023-05-27T17:57:38+00:00

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 }
