Figure 2‒30: Add panel window

Panel title

Specify the panel name up to 255 characters.

Panel type

Select the panel type you want to add from the pull-down menu.

The eight panel types are Trend, Ranking, Numerical value, Gauge, Alert information, Node state, Node state map, and Text. Depending on the selected panel type, different display items can be set.

Organization of this subsection

(1) Trend

If you select Trend as the panel type, the trend data (time-series data) of various metric such as CPU utilization of the specified node is displayed in the panel in a graphical format. It is used for analysis at the time of failure and estimation of future trends.

The following shows an example of the display when Trend is selected in the panel type.

Figure 2‒31: Display example when Trend is selected as the panel type

Target metric

Select the target metric from the pull-down menu. Metrics include CPU utilization and free disk space.

Target node

Set target node by clicking the Add button.

We recommend that you have no more than 20 target node. If it exceeds 20, it will take longer to display the dashboard panel. In addition to the number of target nodes, the dashboard panel display is time-consuming, depending on the following conditions:

The fixed value of the range vector selector specified in PromQL of target metric (promql of the metric definition file)
The number of performance data samples associated with the target nodes for the target metric
The number of label sets for performance data associated with target node in target metric
The duration of Display range setting in the panel
Number of plots in the panel

Display options

Select a display format and legend from the pull-down menus.

Display format

(3) Numerical value

When the Numerical value is selected as the panel type, the latest trend data of the specified node is displayed in numerical format. Use this format for operations that want to check only the most recent metric. Large numbers are displayed so that you can check specific values from a distance.

If you want to monitor the color change of the numerical panel, use it in the case where values such as usage rate and usage are monitored for increase.

The following shows an example of the display when the Numerical value is selected for the panel type.

(4) Gauge

When the Gauge is selected as the panel type, the latest trend data of the specified node is displayed in gauge format. It is used for operations where you want to check only the value of the most recent metric. Large display on gauge, so you can check if it is in Minor or Critical area from a distance.

If you want to monitor the color change of the gauge panel, use it in the case of monitoring the increase in values such as usage rate and usage.

The following shows an example of the display when the Gauge is selected in the panel type.

(5) Alert information

When the Alert information is selected as the panel type, the number of alerts occurring under the target node is displayed. Alerts are displayed when a certain period of time has passed when the metric exceeds the threshold and is canceled when the threshold is less than or equal to the threshold.

You can narrow down the alerts that you want to view. You can also specify only the Alert name for the alert that is displayed.

In the donut chart, the number of alerts per severity is displayed.

Red: Emergency/Alert/Critical
Orange: Error
Yellow: Warning
Green: Notice/Information/Debug
Gray: Others

Click the Alert information panel to display the Instance list window.

[Figure]

Instance list window

Node name: Displays the node on which the alert occurred.
Severity: Displays the severity of the alert.
Alert name: Displays the type of alert that occurred.
Time when threshold was exceeded: Displays the time when the threshold was exceeded.

It becomes an alert state at the time when the time specified in the alert definition has elapsed since the threshold was exceeded.

Time when threshold was exceeded is the first time the threshold was exceeded. This is different from the time when an alert state was triggered after a certain amount of time after being exceeded.
