监控 - Minio - Prometheus的降准采样与无限存储容量保存

前言

Prometheus越来越普及，那么它产生的数据，我们如何来管理呢？
Thanos是一组组件，可以组成具有无限存储容量的高可用性指标系统，并且可以无缝地添加到现有Prometheus部署之上。

您将了解：

借助Thanos sidecar，如何开始将Prometheus数据无缝地无缝上传到廉价的对象存储中。
借助Thanos Store Gateway，如何进一步查询对象存储中的数据。
借助Thanos Querier以简单的方式查询新旧数据。

所有这些使您可以将指标保持在便宜且可靠的对象存储中，从而几乎无限地保留Prometheus的指标。
注意：本帖子使用Docker容器，并公开提供预构建的Thanos，Prometheus和Minio Docker映像。但是，类似的情况也可以与任何其他部署方法（例如Kubernetes或systemd等）一起使用。

一、Prometheus是什么？

请移步官网。

二、步骤

1.准备假数据

2.启动Prometheus

配置文件/root/editor/prometheus0_eu1.yml

global:
  scrape_interval: 5s
  external_labels:
    cluster: eu1
    replica: 0
    tenant: team-eu # Not needed, but a good practice if you want to grow this to multi-tenant system some day.

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['127.0.0.1:9090']
  - job_name: 'sidecar'
    static_configs:
      - targets: ['127.0.0.1:19090']
  - job_name: 'minio'
    metrics_path: /minio/prometheus/metrics
    static_configs:
      - targets: ['127.0.0.1:9000']
  - job_name: 'querier'
    static_configs:

  - job_name: 'store_gateway'
    static_configs:

4.对象存储持续备份

管理一年的数据是可行的，但不容易。长期调整大小，备份或维护此数据非常棘手。最重要的是，Prometheus不会进行任何复制，因此Prometheus的任何不可用都会导致查询不可用。
启动对象存储

[root@host01 ~]# mkdir /root/minio && \
> docker run -d --rm --name minio \
>      -v /root/minio:/data \
>      -p 9000:9000 -e "MINIO_ACCESS_KEY=minio" -e "MINIO_SECRET_KEY=melovethanos" \

重启sidecar

接下来我们了解并部署Thanos Store Gateway。查看thanos命令

[root@host01 ~]# docker run --rm quay.io/thanos/thanos:v0.20.0 --help
usage: thanos [<flags>] <command> [<args> ...]

A block storage based long-term storage for Prometheus.

Flags:
  -h, --help               Show context-sensitive help (also try --help-long and
                           --help-man).
      --log.format=logfmt  Log format to use. Possible options: logfmt or json.
      --log.level=info     Log filtering level.
      --tracing.config=<content>  
                           Alternative to 'tracing.config-file' flag (mutually
                           exclusive). Content of YAML file with tracing
                           configuration. See format details:
                           https://thanos.io/tip/thanos/tracing.md/#configuration
      --tracing.config-file=<file-path>  
                           Path to YAML file with tracing configuration. See
                           format details:
                           https://thanos.io/tip/thanos/tracing.md/#configuration
      --version            Show application version.

Commands:
  help [<command>...]
    Show help.

  sidecar [<flags>]
    Sidecar for Prometheus server.

  store [<flags>]
    Store node giving access to blocks in a bucket provider. Now supported GCS,
    S3, Azure, Swift, Tencent COS and Aliyun OSS.

  query [<flags>]
    Query node exposing PromQL enabled Query API with data retrieved from
    multiple store nodes.

  rule [<flags>]
    Ruler evaluating Prometheus rules against given Query nodes, exposing Store
    API and storing old blocks in bucket.

  compact [<flags>]
    Continuously compacts blocks in an object store bucket.

  tools bucket verify [<flags>]
    Verify all blocks in the bucket against specified issues. NOTE: Depending on
    issue this might take time and will need downloading all specified blocks to
    disk.

  tools bucket ls [<flags>]
    List all blocks in the bucket.

  tools bucket inspect [<flags>]
    Inspect all blocks in the bucket in detailed, table-like way.

  tools bucket web [<flags>]
    Web interface for remote storage bucket.

  tools bucket replicate [<flags>]
    Replicate data from one object storage to another. NOTE: Currently it works
    only with Thanos blocks (meta.json has to have Thanos metadata).

  tools bucket downsample [<flags>]
    Continuously downsamples blocks in an object store bucket.

  tools bucket cleanup [<flags>]
    Cleans up all blocks marked for deletion.

  tools bucket mark --id=ID --marker=MARKER --details=DETAILS
    Mark block for deletion or no-compact in a safe way. NOTE: If the compactor
    is currently running compacting same block, this operation would be
    potentially a noop.

  tools bucket rewrite --id=ID [<flags>]
    Rewrite chosen blocks in the bucket, while deleting or modifying series
    Resulted block has modified stats in meta.json. Additionally
    compaction.sources are altered to not confuse readers of meta.json. Instead
    thanos.rewrite section is added with useful info like old sources and
    deletion requests. NOTE: It's recommended to turn off compactor while doing
    this operation. If the compactor is running and touching exactly same block
    that is being rewritten, the resulted rewritten block might only cause
    overlap (mitigated by marking overlapping block manually for deletion) and
    the data you wanted to rewrite could already part of bigger block.

    Use FILESYSTEM type of bucket to rewrite block on disk (suitable for vanilla
    Prometheus) After rewrite, it's caller responsibility to delete or mark
    source block for deletion to avoid overlaps. WARNING: This procedure is
    *IRREVERSIBLE* after certain time (delete delay), so do backup your blocks
    first.

  tools rules-check --rules=RULES
    Check if the rule files are valid or not.

  receive [<flags>]
    Accept Prometheus remote write API requests and write to local tsdb.

  query-frontend [<flags>]
    Query frontend command implements a service deployed in front of queriers to
    improve query parallelization and caching.

6.Thanos Compactor

Thanos Compactor用来对TSDB block data object storage进行压缩，保留，删除与降准采样操作。

在这里插入图片描述点击块，可显示该块的metadata。

回到Querier web页面，我们查看continuous_app_metric0，勾选Enable Store Filtering
在这里插入图片描述

选择Max 5m downsampling，它使用5m分辨率，并且比原始数据要快。而且，下采样是建立在数据之上的，从来没有在年轻数据上进行过。
在这里插入图片描述

总结

由于Thanos store使用了对象存储，在Prometheus原始数据的同时，也可对数据进行压缩、降准采样、删除等等。Thanos Store使得数据可以无限存储下来。这样可以使得Prometheus近乎无状态。

前言什么是自动化测试自动化测试在很多团队中都是Devops环节中很难执行起来的一个环节，主要原因在于测试代码的编写工作很难抽象，99%的场景都需要和业务强绑定，而且写测试代码的编写工作量往往比编写实际业务代码的工作量更多。在一些很多业务场景中投入产出比很低，适合写自动化测试的应该是那些中长期业务以及一些诸如组件一样的基础库。自动化测试是个比较大的概念，其中分类也比较多，比如单元测试，端对端测试，集
