## configuration 配置 --- [Alertmanager](https://github.com/prometheus/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](https://prometheus.io/webtools/alerting/routing-tree-editor)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](https://github.com/prometheus/alertmanager/blob/master/doc/examples/simple.yml) 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.

']' ] # 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>, ... ']' ] ``` ### <receiver> 接收者是一个或者多个通知集成的命名配置 **Alertmanager在v0.0.4中可用的其他接收器尚未实现。我们乐意接受任何贡献,并将其添加到新的实现中** ``` # The unique name of the receiver. name: <string> # Configurations for several notification integrations. email_configs: [ - <email_config>, ... ] hipchat_configs: [ - <hipchat_config>, ... ] pagerduty_configs: [ - <pagerduty_config>, ... ] pushover_configs: [ - <pushover_config>, ... ] slack_configs: [ - <slack_config>, ... ] opsgenie_configs: [ - <opsgenie_config>, ... ] webhook_configs: [ - <webhook_config>, ... ] ``` ### <email_config> ``` # Whether or not to notify about resolved alerts.
