Configuration

Alertmanager is configured via command-line flags and a configuration file. While the command-line flags configure immutable system parameters, the configuration file defines inhibition rules, notification routing and notification receivers.

The visual editor can assist in building routing trees.

To view all available command-line flags, run alertmanager -h.

Alertmanager can reload its configuration at runtime. If the new configuration is not well-formed, the changes will not be applied and an error is logged. A configuration reload is triggered by sending a SIGHUP to the process or sending a HTTP POST request to the /-/reload endpoint.

Configuration file

To specify which configuration file to load, use the --config.file flag.

./alertmanager --config.file=alertmanager.yml

The file is written in the YAML format, defined by the scheme described below. Brackets indicate that a parameter is optional. For non-list parameters the value is set to the specified default.

Generic placeholders are defined as follows:

<duration>: a duration matching the regular expression ((([0-9]+)y)?(([0-9]+)w)?(([0-9]+)d)?(([0-9]+)h)?(([0-9]+)m)?(([0-9]+)s)?(([0-9]+)ms)?|0), e.g. 1d, 1h30m, 5m, 10s
<labelname>: a string matching the regular expression [a-zA-Z_][a-zA-Z0-9_]*
<labelvalue>: a string of unicode characters
<filepath>: a valid path in the current working directory
<boolean>: a boolean that can take the values true or false
<string>: a regular string
<secret>: a regular string that is a secret, such as a password
<tmpl_string>: a string which is template-expanded before usage
<tmpl_secret>: a string which is template-expanded before usage that is a secret
<int>: an integer value

The other placeholders are specified separately.

A provided valid example file shows usage in context.

The global configuration specifies parameters that are valid in all other configuration contexts. They also serve as defaults for other configuration sections.

`<route>`

A route block defines a node in a routing tree and its children. Its optional configuration parameters are inherited from its parent node if not set.

Every alert enters the routing tree at the configured top-level route, which must match all alerts (i.e. not have any configured matchers). It then traverses the child nodes. If continue is set to false, it stops after the first matching child. If continue is true on a matching node, the alert will continue matching against subsequent siblings. If an alert does not match any children of a node (no matching child nodes, or none exist), the alert is handled based on the configuration parameters of the current node.

[ receiver: <string> ]
# 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 the special value '...' as the sole label name, for example:
# group_by: ['...']
# 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.

  # All alerts that do not match the following child routes
  # will remain at the root node and be dispatched to 'default-receiver'.
  routes:
  # All alerts with service=mysql or service=cassandra
  # are dispatched to the database pager.
  - receiver: 'database-pager'
    group_wait: 10s
    matchers:
    - service=~"mysql|cassandra"
  # All alerts with the team=frontend label match this sub-route.
  # They are grouped by product and environment rather than cluster
  # and alertname.
  - receiver: 'frontend-pager'
    group_by: [product, environment]
    matchers:
    - team="frontend"

`<mute_time_interval>`

A mute_time_interval specifies a named interval of time that may be referenced in the routing tree to mute particular routes for particular times of the day.

name: <string>
time_intervals:
  [ - <time_interval> ... ]

`<time_interval>`

A time_interval contains the actual definition for an interval of time. The syntax supports the following fields:

- times:
  [ - <time_range> ...]
  weekdays:
  [ - <weekday_range> ...]
  days_of_month:
  [ - <days_of_month_range> ...]
  months:
  [ - <month_range> ...]
  years:
  [ - <year_range> ...]

All fields are lists. Within each non-empty list, at least one element must be satisfied to match the field. If a field is left unspecified, any value will match the field. For an instant of time to match a complete time interval, all fields must match. Some fields support ranges and negative indices, and are detailed below. All definitions are taken to be in UTC, no other timezones are currently supported.

time_range Ranges inclusive of the starting time and exclusive of the end time to make it easy to represent times that start/end on hour boundaries. For example, start_time: '17:00' and end_time: '24:00' will begin at 17:00 and finish immediately before 24:00. They are specified like so:

    times:
    - start_time: HH:MM
      end_time: HH:MM

weeekday_range: A list of days of the week, where the week begins on Sunday and ends on Saturday. Days should be specified by name (e.g. ‘Sunday’). For convenience, ranges are also accepted of the form <start_day>:<end_day> and are inclusive on both ends. For example: [‘monday:wednesday','saturday', 'sunday']

days_of_month_range: A list of numerical days in the month. Days begin at 1. Negative values are also accepted which begin at the end of the month, e.g. -1 during January would represent January 31. For example: ['1:5', '-3:-1']. Extending past the start or end of the month will cause it to be clamped. E.g. specifying ['1:31'] during February will clamp the actual end date to 28 or 29 depending on leap years. Inclusive on both ends.

month_range: A list of calendar months identified by a case-insentive name (e.g. ‘January’) or by number, where January = 1. Ranges are also accepted. For example, ['1:3', 'may:august', 'december']. Inclusive on both ends.

year_range: A numerical list of years. Ranges are accepted. For example, ['2020:2022', '2030']. Inclusive on both ends.

`<inhibit_rule>`

An inhibition rule mutes an alert (target) matching a set of matchers when an alert (source) exists that matches another set of matchers. Both target and source alerts must have the same label values for the label names in the equal list.

Semantically, a missing label and a label with an empty value are the same thing. Therefore, if all the label names listed in equal are missing from both the source and target alerts, the inhibition rule will apply.

To prevent an alert from inhibiting itself, an alert that matches both the target and the source side of a rule cannot be inhibited by alerts for which the same is true (including itself). However, we recommend to choose target and source matchers in a way that alerts never match both sides. It is much easier to reason about and does not trigger this special case.

# DEPRECATED: Use target_matchers below.
# Matchers that have to be fulfilled in the alerts to be muted.
target_match:
  [ <labelname>: <labelvalue>, ... ]
# DEPRECATED: Use target_matchers below.

  [ <labelname>: <regex>, ... ]
  
# A list of matchers that have to be fulfilled by the target

source_matchers:
  [ - <matcher> ... ]

# Labels that must have an equal value in the source and target
# alert for the inhibition to take effect.
[ equal: '[' <labelname>, ... ']' ]

`<http_config>`

A http_config allows configuring the HTTP client that the receiver uses to communicate with HTTP-based API services.

# Note that `basic_auth` and `authorization` options are mutually exclusive.

# Sets the `Authorization` header with the configured username and password.
# password and password_file are mutually exclusive.

`<matcher>`

A matcher is a string with a syntax inspired by PromQL and OpenMetrics. The syntax of a matcher consists of three tokens:

A valid Prometheus label name.
One of =, !=, =~, or !~. = means equals, != means that the strings are not equal, =~ is used for equality of regex expressions and !~ is used for un-equality of regex expressions. They have the same meaning as known from PromQL selectors.
A UTF-8 string, which may be enclosed in double quotes. Before or after each token, there may be any amount of whitespace.

The 3rd token may be the empty string. Within the 3rd token, OpenMetrics escaping rules apply: \" for a double-quote, \n for a line feed, \\ for a literal backslash. Unescaped " must not occur inside the 3rd token (only as the 1st or last character). However, literal line feed characters are tolerated, as are single \ characters not followed by \, n, or ". They act as a literal backslash in that case.

In the configuration, multiple matchers are combined in a YAML list. However, it is also possible to combine multiple matchers within a single YAML string, again using syntax inspired by PromQL. In such a string, a leading { and/or a trailing } is optional and will be trimmed before further parsing. Individual matchers are separated by commas outside of quoted parts of the string. Those commas may be surrounded by whitespace. Parts of the string inside unescaped double quotes "…" are considered quoted (and commas don't act as separators there). If double quotes are escaped with a single backslash \, they are ignored for the purpose of identifying quoted parts of the input string. If the input string, after trimming the optional trailing }, ends with a comma, followed by optional whitespace, this comma and whitespace will be trimmed.

Here are some examples of valid string matchers:

Shown below are two equality matchers combined in a long form YAML list.

  matchers:
   - foo = bar
   - dings !=bums

Similar to example 1, shown below are two equality matchers combined in a short form YAML list.

matchers: [ foo = bar, dings != bums ]

As shown below, in the short-form, it's generally better to quote the list elements to avoid problems with special characters like commas:

matchers: [ "foo = bar,baz", "dings != bums" ]

You can also put both matchers into one PromQL-like string. Single quotes for the whole string work best here.

matchers: [ '{foo="bar",dings!="bums"}' ]

To avoid any confusion about YAML string quoting and escaping, you can use YAML block quoting and then only worry about the OpenMetrics escaping inside the block. A complex example with a regular expression and different quotes inside the label value is shown below:

matchers:
  - |
      {quote=~"She said: \"Hi, all!( How're you…)?\""}
