How to get Performance Monitoring Check up and running

The check can be configured to query various indicators on the machine - Processor Utilization, Processor Queue Length, Memory Usage, Network Interface, Physical Disk - to identify performance bottlenecks or critical resources which may affect performance. An Alert is generated where these conditions are not met.

Dashboard Check configuration

Add

  1. Select the device in the north pane of the Dashboard
  2. Go to the Checks tab
  3. Click Add Check
  4. Choose Add 247 > Performance Monitoring Check

    > 40%

    Physical Disk

    average read queue length

    > 2

    average write queue length

    > 2

    average disk time

    > 50%

    Processor Queue

    average queue length per core

    > 2 /Core

    Processor Utilization

    average utilization

    > 70%

    Network Usage Check: includes an Autodetect Network Speed option, when unticked a speed per Mb/s value can be entered.

    Note, where the required files do not exist the Check will fall back to ethtool, as such ethtool is automatically installed on the device.

    Due to the information returned from the network driver, it may not be possible to gather the network usage statistics for some Virtual Machines. In these cases the check will return the message: Could not collect statistics
