Interface http

This plugin automatically instruments the http module.

By default any option set at the root will apply to both clients and servers. To configure only one or the other, use the client and server options.

interface http {
    allowlist?: string | RegExp | ((url) => boolean) | (string | RegExp | ((url) => boolean))[];
    blocklist?: string | RegExp | ((url) => boolean) | (string | RegExp | ((url) => boolean))[];
    client?: boolean | HttpClient;
    enablePropagationWithAmazonHeaders?: boolean;
    enabled?: boolean;
    headers?: string[];
    hooks?: {
        request?: ((span?, req?, res?) => any);
    };
    measured?: boolean | {
        [key: string]: boolean;
    };
    middleware?: boolean;
    propagationBlocklist?: string | RegExp | ((url) => boolean) | (string | RegExp | ((url) => boolean))[];
    server?: boolean | HttpServer;
    service?: any;
    splitByDomain?: boolean;
    validateStatus?: ((code) => boolean);
}
