The Wavefront Query Wizard is a collection of recipes that have been curated by the Wavefront team. The Query Wizard takes a base query and applies the correct string of advanced functions that are needed for the selected recipe. Depending on the selected recipe, additional parameters, such as the number of series to return, may be required. When you’ve completed the query (including additional parameters if required), the Query Wizard displays the data and the completed query. You can then apply the query to your chart.
The Wavefront Query Wizard has the following recipe types:
- Getting Started: Simple recipes, for example, to:
- sum, count, or average your entire data set,
- determine rate of change per second from one data value to the next,
- quickly identify the top ‘X’ number of reported series at the end of your current chart window.
Moving Window: Queries that provide results based on a moving window of time, for example, moving averages or medians for each series over the last X minutes, hours, days, or weeks. This category also includes more advanced recipes, for example, to find the amount of time that’s passed since the last reported value, or recipes for tumbling windows. Here’s a configured moving average query:
- Data Pipeline Management: Recipes that help you learn more about the metrics that your company sends to the Wavefront service. You can determine how many data points are being sent or whether any data points are being blocked.
- Anomaly/Outlier Detection: Recipes that help identify anomalies in your reported data. For example:
- Determining when a reported value is outside a particular range
- Understanding the volatility of your data using variance
- Valculating standard deviations
- other anomaly detection recipes
- Prediction: One recipe that uses window linear regression to predict when two data sets will intersect.
Accessing Query Wizard
You can access the Wavefront Query Wizard from any chart in Wavefront:
- Create a blank chart (Dashboards > Create Chart) or open an existing chart.
Click the wizard icon located to the left of the query line:
The Query Wizard dialog displays and you can select an available recipe. If the query line is already populated with a ts() expression, then that query is used as a base query by the Query Wizard.
Using the Query Wizard
Each recipe requires that you enter a base ts() expression. You have to identify the set of data to associate with the recipe before you start using Query Wizard. Some advanced recipes require knowledge of tags (source tags and point tags) or event parameters such as name and severity. These recipes display which additional parameters are needed for recipe completion.
