What I Touched This Week 2016-12-25

This week I mainly worked on setting up monitoring system using prometheus and grafana.

Monitoring and Logging

• Example of how to write a graylog output plugin
• Add graylog2 stored data in grafana:
  • Type: elasticsearch
  • Connect to the configured elasticsearch instances used in graylog2
  • Leave 『Index name』empty
  • Time field name: timestamp
• Prometheus client libraries keep all metrics, do not use keep increasing value as a tag, such as user id.
• Rsyslog writes logs to file using user and group syslog

Misc

• Recreate Postgres database on macOS installed via Homebew

    rm -rf /usr/local/var/postgres && initdb /usr/local/var/postgres -E utf8
  

• Homebrew 镜像，和其它一些软件源镜像 开源镜像使用帮助列表 [LUG@USTC]

• Maven 镜像仓库

  <mirror>
      <id>nexus-aliyun</id>
      <mirrorOf>*</mirrorOf>
      <name>Nexus aliyun</name>
      <url>https://maven.aliyun.com/repository/public</url>
  </mirror>
  

• An example that caches maven dependencies in Gitlab CI:

  cache:
    paths:
      - .m2/
  
  variables:
    MAVEN_OPTS: "-Dmaven.repo.local=.m2"
  
  maven_job:
    script:
      - mvn clean install
  

• Automate game testing using image recognition

  • Image Recognition for Android and iOS Game Testing
  • Image Recognition in Mobile Game Testing
  • 《腾讯Android自动化测试实战》 也有在测试中使用 OpenCV 做图像识别的例子。
