Alert Receivers

global: # The smarthost and SMTP sender used for mail notifications. smtp_smarthost: 'localhost:25' smtp_from: '[email protected]' smtp_auth_username: 'alertmanager' smtp_auth_password: 'password'

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. # # To aggregate by all possible labels use '...' as the sole label name. # This effectively disables aggregation entirely, passing through all # alerts as-is. This is unlikely to be what you want, unless you have # a very low alert volume or your upstream notification system performs # its own grouping. Example: group_by: [...] 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-X-mails

# All the above attributes are inherited by all child routes and can # overwritten on each.

# The child route trees. routes: # This routes performs a regular expression match on alert labels to # catch alerts that are related to a list of services. - matchers: - service=~"foo1|foo2|baz" receiver: team-X-mails # The service has a sub-route for critical alerts, any alerts # that do not match, i.e. severity != critical, fall-back to the # parent node and are sent to 'team-X-mails' routes: - matchers: - severity="critical" receiver: team-X-pager - matchers: - service="files" receiver: team-Y-mails

    - matchers:
        - severity="critical"
      receiver: team-Y-pager

# This route handles all alerts coming from a database service. If there's
# no team to handle it, it defaults to the DB team.
- matchers:
    - service="database"
  receiver: team-DB-pager
  # Also group alerts by affected database.
  group_by: [alertname, cluster, database]
    - matchers:
        - owner="team-X"
      receiver: team-X-pager
      continue: true

Inhibition rules allow to mute a set of alerts given that another alert is


We use this to mute any warning-level notifications if the same alert is

already critical.

inhibit_rules: - source_matchers: [severity="critical"] target_matchers: [severity="warning"] # Apply inhibition if the alertname is the same. # CAUTION: # If all label names listed in equal are missing # from both the source and target alerts, # the inhibition rule will apply! equal: [alertname, cluster, service]
