Turns out, `dd_url` should only be used in proxy scenarios, not to point
datadog to their EU endpoint - `site` should be used for that.
The `dd_url` setting doesn't affect APM, Logs or Live Process intake
which have their own "*_dd_url" settings.
Fixes#858001d61efb7f1 accidentially changed the
restartTriggers of `datadog-agent.service` to point to the attribute
name (in this case, a location relative to `/etc`), instead of the
location of the config files in the nix store.
This caused datadog to not get restarted on activation of new
config, if the file name hasn't changed.
Fix this, by pointing this back to the location in the nix store.
The override that builds the custom python for integrations-core was
overriding python, but pythonPackages was still being inherited from a
call to `datadog-integrations-core {}`, causing
service.datadog-agent.extraIntegrations to be ignored.
Introduces an option `services.datadog-agent.extraIntegrations` that
can be set to include additional Datadog agent integrations from the
integrations-core repository.
Documentation and an example is provided with the change.
Relates to NixOS/nixpkgs#40399
Refactors the datadog-agent (i.e. V6) module to let users configure
arbitrary checks, not just a limited set, without having to resort to
linking the files manually and updating the systemd unit.
Checks are now configured via a `services.datadog-agent.checks` option
which takes an attribute set in which the keys refer directly to
Datadog check names, and the values are attribute sets representing
Datadog's configuration structure.
With this mechanism users can configure arbitrary integrations, for
example for the `ntp`-check, simply by saying:
services.datadog-agent.checks.ntp = {
init_config = null;
# ... other check configuration options as per Datadog
# documentation
};
The previous check-specific configuration options for non-default
checks have been removed. Disk & network check configuration options
have been kept rather than making them a `default`-value of the
`checks`-option because they will be overridden by user-configurations
in that case.
