### 3.1. <aname='Introduction-1'></a>Introduction
AlertManager, a component of the Prometheus monitoring system, handles alerts sent by client applications such as the Prometheus server. It takes care of deduplicating, grouping, and routing them to the correct receiver. This document outlines how to set up and configure AlertManager using environment variables and the `make init` command. We will focus on configuring key fields like the sender's email, SMTP settings, and SMTP authentication password.
Before initializing AlertManager, you need to set environment variables. These variables are used to configure the AlertManager settings without altering the code. Use the `export` command in your terminal. Here are some key variables you might set:
After setting the necessary environment variables, you can initialize AlertManager by running the `make init` command. This command typically runs a script that prepares AlertManager with the provided configuration.
##### a. Sender's Email (`ALERTMANAGER_SMTP_FROM`)
This variable sets the email address that will appear as the sender in the notifications sent by AlertManager.
##### b. SMTP Configuration
+ **SMTP Server (`ALERTMANAGER_SMTP_SMARTHOST`):** Specifies the address and port of the SMTP server used for sending emails.
+ **SMTP Authentication Username (`ALERTMANAGER_SMTP_AUTH_USERNAME`):** The username for authenticating with the SMTP server.
+ **SMTP Authentication Password (`ALERTMANAGER_SMTP_AUTH_PASSWORD`):** The password for SMTP server authentication. It's crucial to keep this value secure.
The SMTP authentication password can be set using the `ALERTMANAGER_SMTP_AUTH_PASSWORD` environment variable. It's recommended to use a secure method to set this variable to avoid exposing sensitive information. For instance, you might read the password from a secure file or a secret management tool.

For specific configurations related to common email servers, you may refer to their respective documentation:
Setting up and configuring AlertManager with environment variables provides a flexible and secure way to manage alert settings. By following the above steps, you can easily configure AlertManager for your monitoring needs. Always ensure to secure sensitive information, especially when dealing with SMTP authentication credentials.
