AMI's important files

Zabbix AMI contains a number of special files that you should know about

/etc/zabbix/zabbix_ami.yml

this is the more important file, as it handles the config of specific topics like autoscaling checks or SNS notifications. An example of this file (with fake data):

zabbix:
  api:
    user: autoscaler_api_user
    password: i-073672daf01037aea94
sns:
  aws:
    access_key_id: AKK4L6A3OXZZ5HE2POQRU7V
    secret_access_key: cICycAg26hSDpsJwbhZjbaaYlt4Tz3n1xqE7Oxp6X2Hf
    region: us-east-1
  topics:
    not_classified: arn:aws:sns:us-east-1:000000000:Zabbix-General-SNS # Not classified
    information: arn:aws:sns:us-east-1:000000000:Zabbix-General-SNS # Information
    warning: arn:aws:sns:us-east-1:000000000:Zabbix-General-SNS # Warning
    average: arn:aws:sns:us-east-1:000000000:Zabbix-General-SNS # Average
    high: arn:aws:sns:us-east-1:000000000:Zabbix-General-SNS # High
    disaster: arn:aws:sns:us-east-1:000000000:Zabbix-General-SNS # Disaster
sqs:
  delay_seconds: 60
  default_region: us-east-1
  queues:
  - url: https://sqs.us-east-1.amazonaws.com/000000000/zabbix-pro-sqs-queue
    access_key_id: AKIA3OXZZ5HEWUR5A16CNWH
    secret_access_key: 8ttYO3Ba9K6p0C+aj3fH5cDt2eRLHmlkHbMtlrpv18S7KRbC
    region: us-east-1

Currently, this file contains three different sections:

1. zabbix: As we need to connect with Zabbix server to delete old hosts, we need to access throught the API. To do that, we generate a specific user and their login info was configured here.
2. sns: This are the required config for sending alarmas throught SNS. This section contains the data for IAM user, and the SNS topics we need to use.
3. sqs: This section contains config for control AWS autoscaling messages. We define here how much often we check the queue (delay_seconds) and the different queues to check.

/var/log/zabbix-sqs-reader/zabbix-sqs-reader.log

This file register the different events for autoscaling events readed throught SQS.

Before you configure it, you will see that a message like Ops! It looks like the file /etc/zabbix/zabbix_ami.yml hasn’t been configure yet. We better sleep for 5 minutes.. Thats normal and dissapear when you config your zabbix_ami.yml file.
