To break this down step by step, here's what the code or workflow described in your question likely does in the context of using Grafana with Business Charts:
-
Business Charts with MQL Query: You are using Grafana Business Charts to fetch and manipulate data. Grafana queries data from a data source using MQL (Metric Query Language) in this case, which retrieves a set of relevant "stores" (business data points or entities).
-
Set of Stores in JavaScript: The results of the MQL query are being stored in JavaScript code within the Business Charts options. This set represents the stores (likely as an array or object) pulled from the query for further processing.
-
Populating a Dashboard Variable:
- A dashboard variable in Grafana is a dynamic parameter used to populate drop-downs or affect other parts of the dashboard. The JavaScript code is used to populate this variable with the set of stores coming from the MQL query.
- To achieve this, the JavaScript code manipulates or formats the query results and assigns them to the Grafana variable using query manipulations or APIs.
-
Manipulating the URL: The description mentions that you are manipulating the URL. This likely refers to passing values selected from the dashboard variable (stores) as parameters in the Grafana URL. This allows the values to have a cascading effect, dynamically updating other panels in the dashboard when the variable changes. Grafana automatically applies the variable to panel queries when configured.
In summary, the described code and configuration aim to:
- Retrieve store data using an MQL query.
- Populate a Grafana dashboard variable dynamically using JavaScript.
- Utilize the variable to filter and affect other panels on the dashboard.
- Optionally pass variable changes through the URL for dynamic updates.
If you provide code, I can explain further how it implements this process!
