Prometheus rule annotations Learn about recording and alerting rules, configuration, <label_key>: <label_value > annotations: <annotation_key>: <annotation_value > Here's an example of an alerting rule that triggers when CPU usage is above 90% for 5 minutes: All the rules in a group are processed sequentially, while all groups are processed in parallel. ; Configure the rules. yml. While the command-line flags configure immutable system parameters (such as storage locations, amount of data to keep on disk and in memory, etc. We will create a new group named alert_rules. groups: - name: Instances rules: - alert: InstanceDown expr: up == 0 for: 5m labels: severity: page # Prometheus templates apply here in the annotation and label fields of the alert. Templates have the ability to run queries against the local database, iterate Prometheus supports two types of rules which may be configured and then evaluated at regular intervals: recording rules and alerting rules. Alerting rules可以根据Prometheus表达式定义条件，并将触发的报警通知发送到外部服务。当告警表达式在给定时间点产生一个或多个矢量元素(vector elements)，对于这些元素的标签集，警报(alert)将被使为活动(active)。 Go to the Create Prometheus Alert Rule page. This involves adding the path to the rule file in the Prometheus configuration file (prometheus. Labels and annotations. Use a preset metric to create an alert rule. The outcomes of these rules are stored as separate time series data, enhancing query efficiency. ; Labels. In Rancher's UI, we expect a rule group to contain either alert rules or recording rules, but not both. This helps format messages better, reference alert details like labels, values, Learn to write effective Prometheus alert rules for monitoring cloud-native environments. Labels are unique identifiers of an alert instance. 本文来自Prometheus官网手册和Prometheus简介. 文章浏览阅读1.

You can select a rule group from the list to view or edit its details. 3-0 kube-prometheus-0. 3k次，点赞25次，收藏11次。建立一套规范的 Prometheus 告警规则设计标准，为运维监控提供高效的告警分组、收敛、静默抑制和快速响应能力，确保体系的可维护性与扩展性。对于依赖于分布式系统的场景，设计规则时需结合整体健康状态和单节点异常，避免单一指标误触发告警。. Alert Expression Syntax: YAML is the format used to build rules. By default, the rule processing follows the evaluation_interval duration from the Prometheus configuration, but groups Prometheus 支持在告警的注解和标签中，以及在提供的控制台页面中使用模板。模板能够对本地数据库运行查询，迭代数据，使用条件语句，格式化数据等。Prometheus 模板语言基于 Go 模板 系统。 简单告警字段模板 记录规则应为一般形式 level:metric:operations。level 代表规则输出的聚合级别和标签。metric 是度量名称，使用rate() 或 irate()时，除了从计数器剥离 _total，应保持不变。_total off counters when using rate() or irate(). Labels and annotations add additional information about an alert using key/value pairs: Labels are used to differentiate an alert from all other alerts and decide how to manage them. These annotations are added to alerts fired by the rule. Log on to the ARMS console. ; Annotations provide extra details for alert responders to help them understand and address potential issues. Alerting rules are configured in Prometheus in the same way as recordingrules. . It indicates a slower storage backend access or too complex query. In the left-side navigation pane, choose Managed Service for Prometheus > Prometheus Alert Rules. Prometheus's alerting rules are good at figuring what is broken right now, but they are not a fully-fledged notification solution. annotations Prometheus is configured via command-line flags and a configuration file. Rule files use YAML. Another layer is needed to add summarization, notification rate limiting, silencing and alert dependencies on top of the simple alert definitions. In See more Prometheus uses the PromQL (Prometheus Query Language) to create alerting rules. 18 kubelet-1. The alert expression is the core of a Prometheus alert. However their semantics and how both Prometheus and the Alertmanager deal with them are prometheus的rule有两类：AlertingRule: 告警规则；RecordingRule: 表达式规则，用于产生新的指标；1. Prometheus supports two primary types of rules that can be configured and evaluated periodically: Recording Rules: Recording rules are designed for pre-calculating frequently used or computationally intensive queries. 整体框架prometheus的rule管理主要在代码目录prometheus 再看prometheus的web UI，表达式显示也是超过了阈值，由于未满30秒，并未触发真正的告警（Firing），而是进入临时的Pending状态，此时annonation的内容中，配置的哪些变量已经被真实的值替换，显然，这样的内容可以帮我们定位到具体的故障信息 To create rule groups in the Rancher UI, Go to the cluster where you want to create rule groups. Collection of alerting rules. Data Structures 0. To include rules in Prometheus, create a file Templating makes it possible to insert dynamic values into alert messages (annotations). By defining alerting conditions based on PromQL queries, alert rules enable organizations to: Proactively Identify Accessing annotations in CommonAnnotations. An example rules file with an alert would be: The optional for clause causes Prometheus to wait for a certain durationbetween first encountering a new expression output vector element and countingan alert as firing for this element. Alert thresholds depend on nature of applications. ; Click Create. Prometheus supports two types of rules which may be configured and then evaluated at regular intervals: recording rules and alerting rules. This resource is part of the Prometheus Operator and is used to define alerts that should be sent to the Alertmanager. 1. To view all available command-line flags, Prometheus supports templating in the annotations and labels of alerts, as well as in served console pages. Limitations of Prometheus: Inability to suppress alerts and increasing complexity at scale may pose some challenges. myrule. Click Monitoring > Advanced and click Prometheus Rules. 保持数据指标名称不变，可以轻松了解 配置规则. The Prometheus templating language is To do this, access your Stackhero dashboard, select your Prometheus service, and click on "Prometheus alert rules configuration". 前言#. 32. To include rules in Prometheus, create a file containing the necessary rule statements and have Prometheus load the file via the rule_files field in the Prometheus configuration. 小猿姐 阅读 1. rules definition to set a specific severity. Alerting rules are created in Prometheus very similar to how you create recording rules. For instance, if the {env=="prd"} for: 15m labels: severity: critical annotations: summary: Just a summary description: "Just a description" - alert: CPU load expr: expression_used _to_check_load You can enter optional Annotations key/value pairs for the rule. ⚠️ Caution ⚠️. 报警规则允许您基于 Prometheus expression 语言表达式定义警报条件，并向外部服务发送有关触发警报的通知。 每当报警表达式在给定时间内，有一个或多个指标符合报警表达式，则就可以视为这条规则处于活跃的状态（也就是触发了报警）。 Prometheus把产生的警报发给Alertmanager进行处理时，需要在Prometheus使用的配置文件中添加关联Alertmanager的组件的对应配置信息。 Prometheus 告警规则 Prometheus 告警规则概念： 警报规则允许您根据 Prometheus 表达式语言表达式定义警报条件，并将有关触发警报的通知发送到外部服务。每当警报表达式在给定的时间点产生一个或多个向量元素时，警报对于这些元素的标签集算作活动。 类似于记录规则, 告警规则(A Configuring rules. Once the alert rules are defined, the next step is to configure Prometheus to load these rules. The config 0. By focusing on the golden signals, setting meaningful thresholds, and providing Alert rules in Prometheus are essential for proactive monitoring and timely response to system anomalies. They come in two main flavors: recording rules and alerting Effective alerting in Prometheus is crucial for maintaining system reliability and performance. 1配置规则.

Alerting rules have both labels and annotations fields, and when configuring them on the Prometheus side there's no difference between them. 22. We have already added some default alert rules to your Stackhero for Prometheus instance, so you typically won't need to modify the rules-alert. Description. 通常情况，在告警规则文件的 annotations 中使用 summary 描述告警的概要信息，description 用于描述告警的详细信息。同时 Alertmanager 的 UI 也会根据这两个标签值，显示告警信息。为使告警信息具有更好的可读性，Prometheus 支持模板化 label 和 annotations 的中标签 数据库的下一场革命：S3 延迟已降至原先的 10%，云数据库架构该进化了. Prometheus支持两种类型的规则，这些规则可以定期配置，然后定期评估：记录规则和警报规则。 要在Prometheus中包含规则，请创建包含必要规则语句的文件，并让Prometheus通过Prometheus配置中的rule_files字段加载文件， 规则文件使用 Prometheus has a number of required and optional fields for generating rules. yml or, if you wish, create a different file but remember to add the reference to it in the rule_files section in prometheus.

Alerting rules可以根据Prometheus表达式定义条件，并将触发的报警通知发送到外部服务。当告警表达式在给定时间点产生一个或多个矢量元素(vector elements)，对于这些元素的标签集，警报(alert)将被使为活动(active)。 以上就是一个完整 Rules 的配置，如果Prometheus 在周期检测中使用PromQ以env=operations为维度查询，如果当前查询结果中具有标签operations，且返回值都不等于1的时候，发送警报。对于写好的 Rules 可以是常用 promtool 来check ruls.
