How to configure Alert Manager to send mails of alerts

[Akadi Icho]

Hi there,

i am not getting any emails from Alert Manager. the config file is:

--------------------------------------------

global:

  # The smarthost and SMTP sender used for mail notifications.

  smtp_smarthost: 'localhost:25'

  smtp_from: 'alertm...@example.org'

  #smtp_auth_username: 'alertmanager'

  #smtp_auth_password: 'password'

  # The auth token for Hipchat.

  #hipchat_auth_token: '1234556789'

  # Alternative host for Hipchat.

  #hipchat_api_url: 'https://hipchat.foobar.org/'

# The directory from which notification templates are read.

templates: 

- '/etc/alertmanager/template/*.tmpl'

# The root route on which each incoming alert enters.

route:

  # The labels by which incoming alerts are grouped together. For example,

  # multiple alerts coming in for cluster=A and alertname=LatencyHigh would

  # be batched into a single group.

  group_by: ['alertname', 'cluster', 'service']

  # When a new group of alerts is created by an incoming alert, wait at

  # least 'group_wait' to send the initial notification.

  # This way ensures that you get multiple alerts for the same group that start

  # firing shortly after another are batched together on the first 

  # notification.

  group_wait: 30s

  # When the first notification was sent, wait 'group_interval' to send a batch

  # of new alerts that started firing for that group.

  group_interval: 5m

  # If an alert has successfully been sent, wait 'repeat_interval' to

  # resend them.

  repeat_interval: 3h 

  # A default receiver

  receiver: team-Prom-mails

  # All the above attributes are inherited by all child routes and can 

  # overwritten on each.

  # The child route trees.

 

receivers:

- name: 'team-Prom-mails'

  email_configs:

  - to: 'xx...@gmail.com'

------------------------------------------
