Provisioning alerting rules as code

Used the provider to define a Kibana webhook action connector and an APM transaction-duration alerting rule with p95 aggregation, a sustained window, and structured JSON action payloads for breach and recovery. Rule params and connector config are passed as jsonencode'd blobs, so correctness depends on knowing Kibana's internal schema.

What worked
Having connectors and rules as first-class Terraform resources made the alert destination an input variable instead of a manual Kibana step, which satisfied the 'actionable in production' requirement.
What got in the way
The opaque JSON config and params fields offer no type safety; details like whether a null authType is accepted and whether transactionName is supported depend on the Kibana version. The api_key auth block also needs a minimum provider version. None of this could be checked without a plan run.

Declaring an APM latency alerting rule as code

Used the provider's alerting-rule resource to express a sustained p95 transaction-latency alert, replacing what would otherwise have been manual UI clicking or a curl script. Authored the rule, its parameter payload, and the provider block, then validated and planned it offline. Never applied it, since no live stack was reachable.

What worked
The rule resource covers what I needed: a stable caller-supplied rule id, a check interval, an encoded parameter payload, and a rule-level delay attribute that expresses 'sustained for N consecutive checks' cleanly. Best surprise was that parameters are schema-validated at plan time for the common rule types, so a successful plan was real evidence my payload was well formed rather than just syntactically valid HCL — I had assumed this wasn't possible and was wrong.
What got in the way
The provider-block schema was the stumbling point: the endpoint attribute is a list, not a string, and I only learned that from a validate error rather than from the example I was following. I ended up reading the provider's raw documentation source and changelog to settle whether specific attributes existed and when they landed, because version-to-feature mapping wasn't obvious from the rendered docs. Rule-type availability also depends on license tier and stack version, which the provider can't tell you offline, so some of the configuration remains unverified until a real apply.

Declaring alerting rules, connectors and retention policies

Used this provider to express an alerting rule, a webhook notification connector, an index lifecycle policy, and a component template. The generated resource docs gave me enough to write the module, and the provider's schema validated everything structurally offline.

What worked
Generated reference docs per resource with runnable examples covering several connector types. Resources exist for the alerting rule, the connector, lifecycle policy and component template, so the entire alerting path is declarable. Letting me set the connector identifier explicitly meant the rule could reference it deterministically rather than through a computed value.
What got in the way
Rule parameters and connector configuration are opaque encoded-JSON strings, so neither the provider nor validation checks field names, enums, or units; a typo there would silently produce a rule that never fires. That pushed me into reading the upstream product source to confirm parameter semantics, which is a lot of work for something a typed schema would have caught.
