Thresholds

You can define thresholds one of two ways:

• Absolute thresholds are defined based on a number. For example, 80 on a scale of 1 to 150.
• Percentage thresholds are defined relative to minimum or maximum. For example, 80 percent.

On visualizations that support it, Grafana sets default threshold values of:

• 80 = red
• Base = green
• Mode = Absolute

You can add as many thresholds to a panel as you want. Grafana automatically sorts thresholds from highest value to lowest.

1. Navigate to the panel you want to add a threshold to.
2. Open the category Thresholds in the right side options pane.
3. Click Add threshold.
4. Accept the recommendations or edit the new threshold.
   • Edit color: Click the color dot you wish to change and then select a new color.
   • Edit number: Click the number you wish to change and then enter a new number.
   • Thresholds mode - Click the mode to change it for all thresholds on this panel.
5. Click Save to save the changes in the dashboard.

1. Navigate to the graph panel you want to add a threshold to.
2. On the Panel tab, click Thresholds.
3. Click Add threshold.
4. Fill in as many fields as you want. Only the T1 fields are required.
   • T1 - Both values are required to display a threshold.
     • lt or gt - Select lt for less than or gt for greater than to indicate what the threshold applies to.
     • Value - Enter a threshold value. Grafana draws a threshold line along the Y-axis at that value.
   • Fill - Controls whether the threshold fill is displayed.
   • Line - Controls whether the threshold line is displayed.
   • Y-Axis - Choose left or right.
5. Click Save to save the changes in the dashboard.

1. Navigate to the panel you want to add a threshold to.
2. Click the Field tab. (Or Panel tab for a graph panel.)
3. Click the trash can icon next to the threshold you want to remove.
4. Click Save to save the changes in the dashboard.
