OpenStack Horizon - Dashboard

Is the project name of the graphical web interface. Many functions of the daily work can be done comfortably and simply via clicks. For example, you can upload images, create volumes, delete snapshots or configure load balancers and firewalls.

You can easily access the noris.cloud interface via the grey “LOGIN” link in the menu list on this page or simply at https://de-nbg6-1.noris.cloud

OpenStack Ceilometer - The Telemetry Data Collection Service

  • actively retrieves service metrics.
  • collects events and metrics of services, e.g. monitoring notifications.
  • stores and forwards the collected data to DataStores and/or message queues.

 

The following types are defined in ceilometers:

  • Meter:Measures a specific size of a resource e.g. the existence of a running instance or current performance e.g. CPU load of an instance.there is one meter per type of resource e.g. there is a separate cpu_util meter for each instance.one meter is not bound to the existence of a resource. The meter continues to exist when the resource has been deleted. A meter has the following attributes:
    • string name
    • Unit of measurement
    • A type that expresses whether values are saved incrementally, cumulatively or stand-alone (gauge).

 

  • Sample:A data point associated with a specific meter. A sample has the same attributes as the associated meter, but also has a timestamp and value.

 

  • Statistic:A set of data points that have been aggregated over time:
    • count: Counts the number of samples per time unit.
    • max: The maximum per time unit.
    • min: The minimum per time unit.
    • avg: The average per time unit.
    • sum: The sum of all values per time unit.

 

  • Alarm:A set of rules that define a monitor and the current state, as well as actions to be triggered when thresholds are reached.
    Alarms can be used to implement Monitoring-as-a-Service.
    Auto Scaling is another typical application for alarms:

    • O.K.
    • alarm
    • insufficient data
