Grafana is a popular open source data visualization and monitoring tool that allows users to create and share complex dashboards, alerts and graphs with ease. One of the features included in Grafana is the ability to display moving averages.
A moving average is a calculation that takes the average of a set of data points over a given time period. The result is a smoother line that helps to highlight trends and patterns in the data. To calculate a moving average in Grafana, you can use the built-in Moving Average function.
The Moving Average function in Grafana has two parameters:
- Window size: This is the number of data points to use in the moving average calculation. For example, if you have daily data and set the window size to 7, the Moving Average function will take the average of the previous 7 days.
- Series: This is the series or data field to apply the moving average calculation to.
To add a moving average to your Grafana graph, follow these steps:
Open your Grafana dashboard and select the panel where you want to add the moving average.
Click on the “Edit” button at the top right corner of the panel.
In the panel editor mode, click on the “Metrics” tab.
In the Metrics tab, select the metric you want to apply the moving average to.
Once you have selected the metric, click on the “Transform” tab.
Under the “Transform” tab, select “Moving Average” from the drop-down menu.
Set the window size for your moving average by entering a value into the “Window size” field.
Select the series or data field you want to apply the moving average calculation to.
Click on “Apply” to add the moving average to your Grafana graph.
Your moving average will now be displayed on the graph alongside your original data series. You can adjust the window size and other parameters as needed to fine-tune your moving average calculation.
