### Terraform Version ```shell Terraform v1.13.0 on darwin_arm64 ``` ### Terraform Configuration Files The both provider uses `tflog` package for logging, which is required for using `TF_LOG_PROVIDER_{PROVIDER_NAME}`. ```terraform terraform { required_providers { aws = { source = "hashicorp/aws" version = "~> 6.0" } google = { source = "hashicorp/google" version = "~> 6.0" } } } provider "aws" { region = "us-west-2" } provider "google" { project = "my-gcp-project" region = "us-central1" } ``` ### Debug Output ``` % TF_LOG_PROVIDER_AWS=debug terraform plan No changes. Your infrastructure matches the configuration. Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed. ``` ### Expected Behavior Output logs from AWS Provider at the DEBUG level, and no output logs from any other providers ### Actual Behavior No logs from all providers ### Steps to Reproduce ``` % terraform init % TF_LOG_PROVIDER_AWS=debug terraform plan ``` ### Additional Context According to the documentation (https://developer.hashicorp.com/terraform/plugin/log/managing#enable-logging), we can control the log level for a specific provider by setting `TF_LOG_PROVIDER_{PROVIDER_NAME}` environment variable. For example, setting `TF_LOG_PROVIDER_AWS=trace` is expected to output AWS Provider logs at the `TRACE` level while suppressing logs from other providers. However, this simply does not work. I've tested various combinations with `TF_LOG_PROVIDER`, but `TF_LOG_PROVIDER_{PROVIDER_NAME}` appears to have no effect on log output: | TF_LOG_PROVIDER | TF_LOG_PROVIDER_XXX | Expected Provider Log Level | Actual Provider Log Level | |-----------------|---------------------|-----------------------------|---------------------------| | (not set) | DEBUG | **XXX: DEBUG**Others: OFF | ❌ **XXX: OFF** ✅ Others: OFF | | DEBUG | (not set) | XXX: DEBUGOthers: DEBUG | ✅ Works as expected | | DEBUG | INFO | **XXX: INFO**Others: DEBUG | ❌ **XXX: DEBUG**✅ Others: DEBUG | | INFO | DEBUG | **XXX: DEBUG**Others: INFO | ❌ **XXX: INFO**✅ Others: INFO | From my code investigation, Terraform Core is responsible for determining provider log levels. However, the current implementation only recognizes `TF_LOG_PROVIDER` and `TF_LOG` environment variables. It does not consider `TF_LOG_PROVIDER_{NAME}` to set log levels on a per-provider basis. ### References Original discussion: https://discuss.hashicorp.com/t/tf-log-provider-name-does-not-work/39963 ### Generative AI / LLM assisted development? _No response_
