目前Kubernetes中最流行的监控解决方案是使用Prometheus和AlertManager
1. PrometheusOperator
1.1 优势
- 自动化安装
- 将配置资源化
- 灵活的扩展能力
PrometheusOperator将整个监控系统抽象为ServiceMonitor和Prometheus对象
Prometheus对象则可以通过Helm文件配置出多个实例
ServiceMonitor的作用是桥接service和Prometheus,通过ServiceMonitor可以非常方便的通过Prometheus监控服务
Operator作用是监控ServiceMonitor的变化。当ServiceMonitor定义发生变化时，Operator会自动化热更新配置到PrometheusServer

## Enable additional scrape configs that are managed externally to this chart. Note that the prometheus
## will fail to provision if the correct secret does not exist.
## This option requires that you are maintaining a secret in the same namespace as Prometheus with
## a name of 'prometheus-operator-prometheus-scrape-confg' and a key of 'additional-scrape-configs.yaml' that
## contains a list of scrape_config's. The name of the secret may vary if you utilize the "fullnameOverride".
## This feature cannot be used in conjunction with the additionalScrapeConfigs attribute (the helm-generated
## secret will overwrite your self-maintained secret).

总结
在prometheus-operator架构中ServiceMonitor是比较核心的对象，这个对象可以通过values.yaml文件中additionServiceMonitors去配置，通过matchLabels去定义服务的selector策略。需要注意的是path和port，
port的名称需要与service定义的是相同的文章来源：https://www.toymoban.com/news/detail-699541.html
2. Granfana实现监控看板
2.1 Granfana核心特性
- 支持各种主流数据源
- 丰富的图形组件
- 灵活的看板组织方式
- 灵活的权限支持
- 支持OAuth账户支持
2.2 部署文件
grafana:
enabled: true
## Deploy default dashboards.
##
defaultDashboardsEnabled: true
adminPassword: admin
ingress:
## If true, Grafana Ingress will be created
##
enabled: true
## Annotations for Grafana Ingress
##
annotations: {}
# kubernetes.io/ingress.class: nginx
# kubernetes.io/tls-acme: "true"
## Labels to be added to the Ingress
##
labels: {}
## Hostnames.
## Must be provided if Ingress is enable.
##
hosts:
- grafana.local
## Path for grafana ingress
path: /
## TLS configuration for grafana Ingress
## Secret must be manually created in the namespace
##
tls: []
# - secretName: grafana-general-tls
# hosts:
# - grafana.example.com
...
// 在默认的prometheus作为数据源的基础上再添加其他数据源
additionalDataSources: []

3. prometheus-net收集自定义指标
prometheus-net是开源组件,
项目地址:prometheus-net Github地址文章来源地址https://www.toymoban.com/news/detail-699541.html
3.1 组件包
- prometheus-net
- prometheus-net.AspNetCore
3.2 使用场景
- 应用运行状况指标
- 自定义指标
// startup
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
...
endpoints.MapMetrics();// 将metrics映射出来
...
}
// 输出自定义指标
[HttpGet]
public async Task GetMetricsAsync()
{
var r = Metric.NewCustomRegistry();
MetricFactory f = Metric.WithCustomRegistry(r);
r.AddBeforeCollectCallback(() =>
{
f.CreateCounter("counter_v1", "").Inc(100);
});
Response.ContentType = PrometheusConstants.ExporterContentType;
Response.StatusCode = 200;
await r.CollectAndExportAsTextAsync(Response.Body, HttpContext.RequestAborted);
}
