Cloud Monitoring

Cloud Monitoring Application Consists of two main scripts Reorter[reporter.py] and Manager[manage.py]

  • This application can be use to monitor different instances running on cloud and send atomated emails if something went wrong on any instance

Reporter

  • Reporter is the script that is run on each instance and collect data
  • Data collected by reporter
    • CPUUtilization
    • DiskActivity
    • MemmoryUtilization
    • DiskUsage
    • NetworkActivity
    • MetaData

Reporter keep sending data to Monitor through a post request which can be use to monitor instance

The data collected by reported is exposed by endpoints:

  • Available Endpoints
    • GET
      • /get/metrics : Returns all metrics data

    }

      • /get/graph Can be use to make graph of a perticular metrics Query parameter to pass

        • interval = seconds
        • metric = name of metric

      • /get/metadata Returns all metadata about the instance

    • /update/status Can be use to stop or resume the reporter app Query parameter to pass
      • status = {pause,resume,stop}
    • /update/interval Update the time after which the the reporter sends post request to manager

Testing Instance

By default, the Replorter app will use port 5000,

http://13.126.53.116:5000/get/metadata

Manager

  • Manager will recives post request from all the reporter running on different instance
  • Maintain record of every instance in a databse
  • Checks different metrics and sends notification to the user in form of email or slack message.
    • CPUCheck
    • MemoryCheck
    • DiskCheck
  • Available Endpoints
    • POST
      • /app/post/data Data is sent to this endpoint in json format
