configuration 配置

Alertmanager通过命令行和一个配置文件配置。命令行配置不可变的系统参数，而配置文件定义inhibiton规则，通知路由和通知接收者。

可视化编辑器可以帮助构建路由树。

如果想要查看所有命令，请使用命令alertmanager -h。

Alertmanager能够在运行时动态加载配置文件。如果新的配置有错误，则配置中的变化不会生效，同时错误日志被输出到终端。通过发送SIGHUP信号量给这个进程，或者通过HTTP POST请求/-/reload，Alertmanager配置动态加载到内存。

配置文件

使用-config.file指定要加载的配置文件

./alertmanager -config.file=simple.yml

这个配置文件使用yaml格式编写的，括号表示参数是可选的，对于非列表参数，该值将设置为指定的默认值。

<duration>: 与正则表达式匹配的持续时间[0-9]+(ms|[smhdwy])
<labeltime>: 与正则表达式匹配的字符串[a-zA-Z_][a-zA-Z0-9_]*
<filepath>: 当前工作目录下的有效路径
<boolean>: 布尔值： false 或者 true。
<string>: 常规字符串
<tmpl_string>: 一个在使用前被模板扩展的字符串

其他占位符被分开指定，一个有效的示例，点击这里

全局配置指定的参数在所有其他上下文配置中是有效的。它们也作为其他区域的默认值。

global:
  # ResolveTimeout is the time after which an alert is declared resolved
  # if it has not been updated.
  [ resolve_timeout: <duration> | default = 5m ]

  # The default SMTP From header field.
  [ smtp_from: <tmpl_string> ]
  # The default SMTP smarthost used for sending emails.
  [ smtp_smarthost: <string> ]
  # SMTP authentication information.
  [ smtp_auth_username: <string> ]
  [ smtp_auth_password: <string> ]
  [ smtp_auth_secret: <string> ]
  # The default SMTP TLS requirement.
  [ smtp_require_tls: <bool> | default = true ]

  # The API URL to use for Slack notifications.
  [ slack_api_url: <string> ]

  [ pagerduty_url: <string> | default = "https://events.pagerduty.com/generic/2010-04-15/create_event.json" ]
  [ opsgenie_api_host: <string> | default = "https://api.opsgenie.com/" ]
  [ hipchat_url: <string> | default = "https://api.hipchat.com/" ]
  [ hipchat_auth_token: <string> ]

# Files from which custom notification template definitions are read.
# The last component may use a wildcard matcher, e.g. 'templates/*.tmpl'.
templates:
  [ - <filepath> ... ]

# The root node of the routing tree.
route: <route>

# A list of notification receivers.
receivers:
  - <receiver> ...

# A list of inhibition rules.
inhibit_rules:
  [ - <inhibit_rule> ... ]

一个路由块在路由树和它的孩子中定义了一个节点。如果不设置，它的可选配置参数从父节点中继承其值。

每个警报在已配置路由树的顶部节点，这个节点必须匹配所有警报。然后遍历所有的子节点。如果continue设置成false, 当匹配到第一个孩子时，它会停止下来；如果continue设置成true, 则警报将继续匹配后续的兄弟姐妹节点。如果一个警报不匹配一个节点的任何孩子，这个警报将会基于当前节点的配置参数来处理警报。

[ receiver: <string> ]
[ group_by: '[' <labelname>, ... ']' ]

# Whether an alert should continue matching subsequent sibling nodes.
[ continue: <boolean> | default = false ]

# A set of equality matchers an alert has to fulfill to match the node.
match:
  [ <labelname>: <labelvalue>, ... ]

# A set of regex-matchers an alert has to fulfill to match the node.
match_re:
  [ <labelname>: <regex>, ... ]

# How long to initially wait to send a notification for a group
# of alerts. Allows to wait for an inhibiting alert to arrive or collect
# more initial alerts for the same group. (Usually ~0s to few minutes.)
[ group_wait: <duration> ]

# How long to wait before sending notification about new alerts that are
# in are added to a group of alerts for which an initial notification
# has already been sent. (Usually ~5min or more.)
[ group_interval: <duration> ]

# How long to wait before sending a notification again if it has already
# been sent successfully for an alert. (Usually ~3h or more).
[ repeat_interval: <duration> ]

# Zero or more child routes.
routes:
  [ - <route> ... ]

示例

# The root route with all parameters, which are inherited by the child
# routes if they are not overwritten.
route:
  receiver: 'default-receiver'
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 4h
  group_by: [cluster, alertname]
  # 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
    match_re:
      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]
    match:
      team: frontend

<inhibit_rule>

一个inhibition规则是在与另一组匹配器匹配的警报存在的条件下，使匹配一组匹配器的警报失效的规则。两个警报必须具有一组相同的标签。

# Matchers that have to be fulfilled in the alerts to be muted.
target_match:
  [ <labelname>: <labelvalue>, ... ]
target_match_re:
  [ <labelname>: <regex>, ... ]

# Matchers for which one or more alerts have to exist for the
# inhibition to take effect.
source_match:
  [ <labelname>: <labelvalue>, ... ]
source_match_re:
  [ <labelname>: <regex>, ... ]

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