Monitoring > Cloud Monitoring > Console User Guide

This document explains the basics of using the Cloud Monitoring service.

Dashboard

In Monitoring > Cloud Monitoring > Dashboard, you can create chart widgets and configure dashboards to view various metrics collected from resources created by NHN Cloud services.

Auto-refresh view periods

The metric data view period for user dashboards defaults to retrieving data up to five minutes prior to the current time. The default auto-refresh interval is 1 minute.

Customize the view period

If you set a custom duration, auto-refresh is disabled.

View Mode/Edit Mode

Dashboard view mode

Dashboard edit mode

The dashboard has two modes: view mode and edit mode.

View Mode Header

Dashboard appears in the view mode by default, and to modify a dashboard or widget, you must click the Edit mode toggle to switch to the edit mode.

Edit Mode Header

In the edit mode, you can edit the name or description of a dashboard, or clone or delete a dashboard. You can also edit each widget, or reposition and clone widgets.

Full save notification modal

Any changes you make to the widget, such as adding a widget or modifying its location and size, don't take effect until you click Save All. If you don't, you'll see a save notification modal, and any unsaved changes will disappear.

Create a Dashboard

Add Dashboard Modal

In the view mode, click + to the right of the Dashboard tab to open the Add dashboard modal.

Blank dashboard

If no dashboards have been created, you'll see + Create Dashboard.

After creating a dashboard

Enter a dashboard name and dashboard description. The dashboard name is a required value, and can be set to a duplicate name, but we recommend using a unique name whenever possible. Dashboard description is an optional value and you can enter something descriptive of the dashboard.

Set up a Dashboard

Dashboard example

You can add widgets and groups of widgets to a dashboard. You can add up to 12 widgets per dashboard, and they are added to the bottom of the dashboard when you add them.

Widget examples

Widgets are the smallest unit of organization for a dashboard. They can be created by clicking + Add Widget or by selecting Add Widget, Add Widget Template from the drop-down list of the corresponding button. The size and position of widgets can be freely changed in dashboard edit mode.

Widget group example

Widget groups allow you to manage multiple widgets by grouping them together. Widget groups can be collapsed or expanded to hide and show multiple widgets, and the height and width of the widget group automatically adjusts to the size of the widgets within the group.

Add/Edit a Widget and Widget Group

Add Widget button area

Widgets and widget groups can be added in both view mode and edit modes. However, to modify widgets and widget groups, you must switch to the edit mode.

Add a Widget

About the Add Widget screen

Add widget gives you the freedom to create your own chart widget with the metrics and filters you want. The widget name, graph type, service, and Metrics settings > Metrics are required values and must be filled in. A single widget can only represent a single service. However, you can select multiple metric items.

Select the Add Widget screen metrics item and click

Each time you select a metric item, elements are added at the bottom of the screen that allow you to set filters and a legend for the metric item. You can only label one metric filter per type, and all filters are finally applied in the form of an & operation. Therefore, when applying multiple filters, the search results for a condition value will only show search results that meet all of the previously set filter criteria. Depending on the operator and condition values of the filters you added earlier, there may be no more condition values to choose from.

The legend is a name to distinguish the metric data viewed by each metric item. When you add a metric item, it automatically populates a suggested name by default.You can add any text before or after the placeholder wrapped in double curly braces syntax {{ }}. If you don't enter any text, it will concatenate and expose any label properties the indicator item has. Select Units to specify the y-axis title and units to be exposed in the chart. The actual value of the metric item is exposed to 15 decimal places (rounded to the 16th place, except when Percent (0.0-1.0) is selected, in which case the value is converted to 0-100 and exposed), without support for separate formatting based on units. The Y-axis position setting allows you to choose between Auto, Left, and Right for the Y-axis position of the metric item. When adding a metric item, the Auto value is selected by default. If all metric items are selected Auto, they will be sequentially positioned on the Y-axis as either Left or Right. If a metric exists with a left or right y-axis position, it will be placed in the same y-axis direction. If any metric items have the same unit and y-axis position, they are represented on the same y-axis.

Add widget screen preview layer

After you change the graph type or modify the metric item filters, you can preview how the chart widget will look with your changes. Click the Preview toggle in the top-right corner of the screen to open or close the preview layer, where you can see the chart widget in real time with your filters and legend values applied. The preview layer is adjustable for left and right width.

Add a Widget Template

Add Widget Template Modal

Widget templates are a quick and easy way to create widgets using pre-configured widget metric items. After adding the widget, you can edit the widget to add filters to the metric items or change the metric items and names. Note that some widgets added through widget templates can only be deleted and not edited.

Add a Widget Group

Add Widget Group Modal

You can add a group of widgets to your dashboard through Add widget group. To add a widget to a widget group, simply drag the title area at the top of the widget in edit mode and move it inside the widget group.

Widget groups can be edited just like widgets, and to edit a widget group, you need to enter edit mode.

  • Click Delete Group to remove only the group, leaving the widget's location and size information intact.

Resizing widgets

Once you're in edit mode, you can resize the widget by dragging the bottom right corner, or reposition it by dragging the top area of the widget.

Widget context menu

  • You can delete the widget by clicking Delete.
  • You can duplicate a widget in a dashboard by clicking Clone Widget to Other Dashboard. The cloned widget is added at the bottom.

Download Widget Data

Download Widget Data menu

You can download all the widget data for a dashboard as a .png, .csv, or .xlsx file. The files are saved with the dashboard name, and in the case of .csv files, they are downloaded as a .zip file compressed with the dashboard name. Inside it contains individual .csv files with the name of each widget. For .csv and .xlsx files, you can only download up to 3 months of data based on the start date. If the view period is less than one month, data is provided in 5-minute intervals, and if it is more than one month, data is provided in 1-day intervals. The longer the view period you specify or the more metric data the widget and the widget contains, the longer the download might take.
