Jeager

功能

1. 监控分布式工作流程并排除故障
2. 识别性能瓶颈
3. 追踪根本原因
4. 分析服务依赖关系

部署

• 部署 Deployment — Jaeger documentation (jaegertracing.io)

• 支持 clickhouse jaegertracing/jaeger-clickhouse: Jaeger ClickHouse storage plugin implementation (github.com)

• 使用 prometheus 监控 Service Performance Monitoring (SPM) — Jaeger documentation (jaegertracing.io)

• 使用 elasticsearch docker - How to configure Jaeger with elasticsearch? - Stack Overflow

• github issue jaeger-collector: Failed to init storage factory · Issue #931 · jaegertracing/jaeger (github.com)

• Service Performance Monitoring (SPM) — Jaeger documentation (jaegertracing.io)

可以看到指标了

jaeger的 trace 展示与 grafana，signoz 不一致

出现异常，为修改相关代码，先前可以在Prometheus观测到traefik的指标【已修复】

Otel-collector 的 Pipeline

理解了整个 otel-collector 的 Pipeline 的流程和各个组件的功能

• spanmetrics 是一个 connector
• 它可以作为一个 receiver 【可以接收上游 trace pipeline 的 spanmetrics - 它作为一个 exporter】来开启一个metric 的 pipeline
• 它可以作为一个 exporter 【存储 trace pipeline 的 span 指标】
• spanmetrics 定义为 processer，可以在 trace 的 pipeline 中将 span的指标导出到 Prometheus 里

可以观测到 traefik、venus、profile 上报的 metrics！

明日待办

1. 压测 jaeger
2. 测试替换 jaeger 的数据库为 es
