Performance Budgets are an effective way of making sure regressions in performance are noticed and addressed quickly. You can set Budgets against every metric in Calibre:
To create a Budget, navigate to Site → Budgets and click the Add a Budget button. On Add a Budget page, you will be able to select a metric to track and a range of settings for your Budget:
Start by selecting a metric to track. Once you choose one, the chart below populates with historical tracking information (if present), and how frequently specific measurements occur. The highest bars mean the most common reading. The chart is re-generated each time you select specific Pages or Test Profiles.
The chart is colour-coded accordingly to Slow, Average and Fast range recommendations (for timing-based metrics) or Small, Average and Large recommendations (for byte size-based metrics).
With this context, you can select a Budget value that is informed by your use case but also meets recommendations for best performance.
You can set the same Budget for all, one or a custom selection of Pages within a given Site. Once you choose Select Pages, you will see a list of all Pages in your Site.
It’s possible to set a single Budget against all Test Profiles in use. You can also set separate Budgets for each Test Profile. Since different Test Profiles produce varying monitoring data, it’s important to track Budgets for them separately.
We recommend setting separate Budgets when dealing with vastly different environment set-ups, such as Desktop with Cable connection, Motorola Moto 3G or turning off ads and third parties.
Calibre will notify the creator of the Budget and anyone who subscribes to Budget notifications each time there’s a change in Budget status. You can choose to:
To view Budgets, navigate to Site → Budgets page. You can filter Budgets by choosing their status or device type.
Click on the Budget card, to access the View Budget page with more details about Pages and Test Profiles and their Budget status. You can also see who created and edited the Budget, and when.
To edit or delete an existing performance Budget, go to Site → Budgets and click on a relevant Budget card. On the View Budget page, you will be able to Edit or Delete a Budget.
