- 具体的部署是：用prometheus抓取thanos receiver的10909端口，然后grafana再请求这个prometheus
- 具体的JSON配置请见最后
- 本文的一些监控配置，参考了这篇文章：Prometheus 内置的一些 Metrics
- 在grafana中导入报表配置，请看这里
1.remote write接口的http请求统计
- metric为：http_requests_total
- counter类型
- 监控曲线统计的表达式为：
sum by (instance) (rate(http_requests_total{handler="receive",method="post",instance="$instance"}[1m]))*60
2.读请求数据
- 读请求是GRPC协议
- metric为：grpc_server_handled_total, counter类型
- 查询表达式：
sum by (grpc_method) (rate(grpc_server_handled_total{instance="$instance"}[1m]))*60
3.进程内存：
- 这个指标非常重要：如果请求量太大，或者time series太多，都会导致receiver因为内存不足而OOM
- metric为：process_resident_memory_bytes
- 查询表达式：
sum by (instance) (max_over_time(process_resident_memory_bytes{instance="$instance"}[1m]))/1024/1024/1024
4.核心指标：series/chunk/sample
- sample数量一般是remote write请求中所带的指标数据的总量
- time series是所有metric的所有label组合的总量。这个量太大必然导致receiver内存用尽
- chunk数据量一般与time series数据正相关
- time series总量:
max by () (max_over_time(prometheus_tsdb_head_series{instance="$instance"}[1m]))
- time series每分钟新增：
sum by () (rate(prometheus_tsdb_head_series_created_total{instance="$instance"}[1m]))*60
- sample每分钟变化情况：
sum by () (rate(prometheus_tsdb_head_samples_appended_total{instance="$instance"}[1m]))*60
