请问flink push Prometheus PushGateway 有多个job,如何监听任何job失败则告警并输出jobid?
以下为热心网友提供的参考意见
要监听Flink多个job的失败并输出jobid,你可以使用Flink的Metrics系统和Prometheus的Alertmanager配合实现。以下是一个基本的步骤: a. 确保你的Flink作业暴露了必要的metrics,例如flink_job_status和flink_task_manager_num_failed_tasks等。 b. 在Prometheus配置文件中,设置一个抓取目标来获取Flink作业的metrics,例如:
- job_name: 'flink_jobs'
static_configs:
- targets: ['flink-jobmanager:9249'] # 替换为你的Flink JobManager的实际地址和端口
c. 创建一个Prometheus规则文件,定义一个alert规则来监控job状态和失败任务数,如下所示:
yaml
groups:
- name: flink_job_alerts
rules:
- alert: FlinkJobFailed
expr: sum(flink_job_status{status="FAILED"}) by (job_id) > 0
for: 1m
labels:
severity: critical
annotations:
summary: Flink Job {{ $labels.job_id }} has failed
description: Flink job {{ $labels.job_id }} has entered a FAILED state.
- alert: FlinkTaskFailure
expr: sum(flink_task_manager_num_failed_tasks) by (job_id) > 0
for: 1m
labels:
severity: warning
annotations:
summary: Flink Job {{ $labels.job_id }} has failed tasks
description: Flink job {{ $labels.job_id }} has failed tasks, please check the job status.
d. 配置Alertmanager来接收这些告警,并根据需要设置通知方式(如邮件、短信、 Slack 等)。
以下为热心网友提供的参考意见
要监听任何Flink job失败并输出jobid,可以使用Prometheus的Alertmanager和告警规则。具体步骤如下:
- 在Prometheus配置文件中添加PushGateway地址:
scrape_configs: - job_name: 'flink' static_configs: - targets: ['']
- 在Alertmanager配置文件中添加告警规则:
“`
groups:
- name: flink_alerts
rules:- alert: FlinkJobFailure
expr: flink_job_failure_total{status=”failed”} > 0
for: 1m
labels:
severity: critical
annotations:
summary: “Flink Job failed”
description: “{{$labels.instance}} of job {{$labels.job_name}} has failed.”
“`
- alert: FlinkJobFailure
- 在Alertmanager配置文件中添加接收器(例如email或Slack):
“`
receivers:
- name: ’email’
email_configs:- to: ”
from: ”
smarthost: ‘:’
auth_username: ”
auth_password: ”
“`
- to: ”
- 重启Prometheus和Alertmanager服务。
- 如果有任何Flink job失败,Alertmanager将发送一封电子邮件或Slack消息,其中包含失败的jobid。
