Configuration

The Dynatrace OneAgent serverless plugin will configure serverless and serverless-webpack to bundle Dynatrace npm module for PaaS.

In regular serverless projects, the plugin will npm install and tailor Dynatrace npm module for PaaS during serverless packaging process. It will also reconfigure the function handler definition to load Dynatrace OneAgent at function instance startup.

In serverless-webpack case, the plugin will configure webpack to include Dynatrace npm module for PaaS into the bundle. The resulting deployment zip file will contain the Javascript file for the handler function and a node_modules folder with Dynatrace OneAgent.

Enabling your serverless project for Dynatrace OneAgent is a two steps process:

1. add plugin to serverless.yml
2. specify OneAgent options

Add plugin to serverless.yml

Extend the plugins list of the projects serverless.yml file with @dynatrace/serverless-oneagent plugin.

service: dynatrace-oneagent-sample

plugins:
  - '@dynatrace/serverless-oneagent'

provider:
  name: aws
  runtime: nodejs6.10

functions:
  hello:
    handler: index.hello
    events:
      - http:
          method: GET
          path: hello

Specify OneAgent options

OneAgent options can be specified in serverless.yml file or serverless (sls) command line.

The option string can be obtained from serverless configuration screen (Deploy Dynatrace > Setup Serverless integration).

Add following to serverless.yml:

custom:
  serverless-oneagent:
    options: '{"server":"...","tenant":"...", "tenanttoken":"..."}'

If you do not want to add OneAgent options to the serverless.yml , the options can be specified as a command line argument to serverless (sls) command.

serverless deploy --dt-oneagent-options='{"dynatraceTagPropertyPath":"headers.x-dynatrace","server":"...","tenant":"...","tenanttoken":"..."}'
