When you enable HTTP proxy forwarding, you create a single point through which multiple machines
send requests to an external server. For logging, you may not want to have all traffic forwarded
through the proxy.
This procedure explains how to disable HTTP proxy forwarding for specific hosts in your
overrides file.
Procedure
Disable proxy forwarding for logging for specific hosts by setting the
logger.envVars property in overrides.yaml:

Disable proxy forwarding for logging for specific hosts by setting the [`logger.envVars`](/apigee/docs/hybrid/v1.15/config-prop-ref#logger-envvars) property in `overrides.yaml`: \n\n ```\n logger:\n ...\n envVars:\n NO_PROXY: '\u003ccomma-separated-values\u003e'\n ```\n\n for example: \n\n ```\n envVars:\n NO_PROXY: 'kubernetes.default.svc,oauth2.googleapis.com,logging.googleapis.com'\n ```\n\n\n The `logger.envVars` property allows you to pass in environment variables\n supported by Fluent Bit. See\n [NO_PROXY](https://docs.fluentbit.io/manual/administration/http-proxy#no_proxy)\n in the Fluent Bit documentation.\n2. Apply the changes with the `apigee-telemetry` chart: \n\n ```\n helm upgrade telemetry apigee-telemetry/ \\\n --namespace apigee \\\n --atomic \\\n -f OVERRIDES_FILE\n ```\n | **Note:** If you see an error saying `Error: UPGRADE FAILED: \"telemetry\" has no deployed releases`, replace `upgrade` with `install` and try the command again.\n\nSee also\n\n- [`logger.envVars`](/apigee/docs/hybrid/v1.15/config-prop-ref#logger-envvars) in the Configuration properties reference.\n- [Configure forward proxying for API proxies](/apigee/docs/hybrid/v1.15/forward-proxy)."]]
