This document describes overall usage scenarios, from configuring dashboard to creating notifications.
To use Cloud Monitoring, follow the steps below.

  • Select the service
    Cloud Monitoring is provided by default when you create a project.
    So you can use the service after creating a project without doing anything else.
    To create a project, see the NHN Cloud Console User Guide.
  • Set up metric collection
    Set up metric collection for each service.
  • Configure the dashboard
    Add widgets to your dashboard to customize it.

  • Metrics for Instance and GPU Instance are provided by default.
  • Only enabled services collect metrics. Please note that the service is enabled.
  • Clicking the Metrics Collection Settings toggle to disable it will stop collecting that metric and it will not appear in the dashboard.

Configure the dashboard

You are now ready to configure your dashboard.
Let's create a dashboard and add a widget.

Create a dashboard

  1. +Create Dashboard. Select the image
  2. Enter a name and description for your dashboard, then click Confirm. image
  3. Check the created dashboard.

Add widgets

  1. Click Add Widgetto go to the Add widget page. Add an image
  2. Enter a name for the widget, and select a graph type and service.
  3. In Manage Metrics, you can only select services that have collection settings enabled.
  4. Select the resource type and metric items that correspond to the selected service.

  5. You'll see boxes to set filters and a legend for each selected metric item. image

  6. You can set filters to selectively see only the metrics you want.

  7. For example, to monitor specific instances that are only in the Korea (Pangyo) region, you would set it up like this
    • Click +Add to add a filter.
    • Set the filter Region``=``kr1 (Korea (Pangyo)) in the order of label, operator, and condition.
    • Add a filter to select Instances = {Instance name}by label, operator, and condition.
    • This will display the specific instance metrics for the KR1 (Korea (Pangyo)) region in the graph.
  8. You can set the name of the legend, units, and position of the y-axis as needed.
  9. If the metrics have the same units, they will be displayed as one y-axis.

  10. In Y-Axis Positioning, Auto will automatically position the y-axis in left, then right order if the units are different for each metric. image

  11. Use the preview feature to make sure the graph looks the way you want.

  12. Once checked, click Add to add the widget to your dashboard. image
