lambda-logging-demo

A Lambda function for:

• shipping logs to Logz.io (hosted ELK stack)

Deployment

1. insert the logstash_host, logstash_port and token in the serverless.yml file (under the ship-logs-to-logzio function's environment variables).

token: your Logz.io account token. Can be retrieved on the Settings page in the Logz.io UI. logstash_host: if you are in the EU region insert listener-eu.logz.io, otherwise, use listener.logz.io. You can tell which region you are in by checking your login URL - app.logz.io means you are in the US. app-eu.logz.io means you are in the EU. logstash_port: this should be 5050, but is subject to change. See this page for details.

for example:

ship-logs-to-logzio:
  handler: functions/ship-logs/handler.handler
  description: Sends CloudWatch logs to Logz.io
  environment:
    logstash_host: listener.logz.io
    logstash_port: 5050
    token: CduNgGwuFFeUVzbXvqVDXoGkjxEdKzc9

2. run ./build.sh deploy dev to deploy to a stage called "dev"

3. once deployed, take a note of the ARN for the function. Now you can deploy the auto-subscribe-log-group-to-arn app from the Serverless Applciation Repository (here) and pass in the ARN for the ship-logs-to-logzio function.
