##Dependences

• Run
  • java(1.7 or later)
  • Prometheus
• Compile
  • maven
  • java(1.7 or later)

##Installation

• Set up your Zookeeper, Kafka, Druid(If you have) for monitoring.

• Set up Prometheus/.

  • Download a Prometheus release 0.16.0 from https://github.com/prometheus/prometheus/releases and set it up following http://prometheus.io/docs/introduction/getting_started/, you can stop before here if you don't want to go deep into prometheus. And don't worry, it is extremely easy.

  • Add a job to scrape DCMonitor's metrics, job config should looks like:

     - job_name: 'dcmonitor'
     scrape_interval: 5s
     scrape_timeout: 10s
     target_groups:
     - targets: ['localhost:8075']
    

    Here localhost:8075 is the DCMonitor's host:port which web service listen on (configured in application.properties). The completed example is here.

    After that go to http://<hostname>:9090/status, expected to see the dcmonitor endpoints in targets section. It is in UNHEALTHY state because we havn't set up DCMonitor web service yet!

• Compile & deploy DCMonitor

  • Compile

     git clone git@github.com:shunfei/DCMonitor.git
     cd DCMonitor
     ./build.sh
    

    Then a target folder will be generated under root folder.

  • Deploy

    You only need to deploy target, run.sh, config to target machine.

    Modify configurations in config/config.json and application.properties.

    Run run.sh, will start the DCMonitor web service. If every thing is fine, visit http://<hostname>:8075 to enjoy!
