Analyze consumption

After creating partitions, use the Consumption page to identify unexpected spikes, understand growth, and compare usage across partitions. The Consumption page displays consumption for the selected product, resource group, resource, and time range. For applicable global partition views, the page also displays contractual volume consumed and contract duration elapsed. The page includes budget thresholds and consumption statistics for child partitions. To compare telemetry rates with the system limits configured for your tenant, use the Consumption System Limits dashboard. That dashboard is the source of truth for system limit thresholds, utilization, and data dropped by system limit enforcement.

​

Analyze with the Consumption page

To analyze data consumption in the Consumption page, in the navigation menu, click Go to Admin and then select Control > Consumption.

​

Select consumption data

Use the page controls to define the consumption data to analyze:

1. Select a Product, Resource Group, and Resource. The available resource groups and resources depend on the selected product.
2. Review the unit selector, if present. Select Credits or Native units when both options are enabled. The page uses credits when the selection includes multiple resources.
3. Select the page time range. The available ranges include This month and Previous month.

The page time range controls which data the page retrieves. The Time window menu in the Consumption chart controls how the retrieved data is aggregated.

​

Review partition statistics

The partition summary is named for the selected partition. For example, the global partition displays the Global Partition summary. The summary includes the following statistics:

• Use Consumed to view the total data consumed and persisted during the selected time range. For the global partition, this statistic also displays the percentage of contractual volume when contract details apply to the selected range.
• Use Dropped by budgets to view the total data dropped by budget enforcement during the selected time range.
• If Dropped by system limits appears, use it to view the total data dropped by system limit enforcement during the selected time range. Click View to open the Consumption System Limits dashboard for the same time range.
• Use Change over time to view the percentage change in consumption compared to the preceding period. The comparison period depends on the selected time range.

For the global partition, review Contract duration elapsed when the selected time range falls within the contract period. Archived and unpartitioned partitions display corresponding badges.

​

Analyze consumption trends

In the Consumption chart, use the Time window menu to select how the chart aggregates consumption:

• Use Per second to detect spikes.
• Use Daily, Weekly, and Monthly (Cumulative) to identify gradual growth or sustained overconsumption.
• Use Rolling 30 minutes, Rolling 1 hour, Rolling 3 hours, Rolling 1 day, or Rolling 7 days to identify recurring changes over rolling periods.

Use the Group by menu to select how the chart divides the data:

• Consumed vs dropped compares persisted volume with dropped volume.
• Consumed by partition identifies which partitions account for the most consumption.
• Consumed by product compares consumption across telemetry products.
• Consumed by resource compares the resources within the selected product.
• Dropped by budget or Dropped by reason compares dropped volume. If Dropped by reason appears, use it to separate budget drops from system limit drops.
• Dropped by partition identifies which partitions account for dropped data.

If the chart includes budget thresholds, dashed lines indicate the threshold values. Use Show thresholds to show or hide these lines. When Go to Explorer appears for log data, click it to investigate the underlying data in Logs Explorer.

​

Review budgets

The Budgets table displays the thresholds that apply to the selected partition. Use the following columns to review each threshold:

• Product and Resource Group identify the data that the threshold governs.
• Time window identifies the period over which the threshold is evaluated.
• Action identifies whether the threshold sends a warning alert, sends a critical alert, or drops data. When an action has an associated monitor, click the action to open that monitor.
• Threshold displays the received volume as a percentage and value relative to the threshold. The received volume includes consumed and dropped data.
• View selects the threshold’s product and resource group, resets the resource to All, restores the threshold’s original unit, and selects the matching chart time window.

The Budgets table header reports the selected partition’s budget status as Ok, Alerting, or Dropping. A partition without a budget displays no status badge, and the table displays No budget. The table can also display a system limit as Per second (max consumption rate). The Consumption System Limits dashboard remains the source of truth for system limit thresholds and enforcement.

​

Compare child partitions

The Child Partitions table compares the selected partition’s immediate children. Search for a partition by name, or sort the table by the following columns:

• Order: The order in which each child partition matches data.
• Partition: The child partition name. Click a linked name to open that partition’s Consumption page. Unpartitioned rows aren’t linked. Archived and unpartitioned rows display corresponding badges.
• Consumed: The partition’s percentage of its parent’s consumed volume and its absolute consumed value.
• Dropped: The partition’s percentage of its parent’s dropped volume and its absolute dropped value.
• Change over time: The percentage change in consumption compared to the preceding period. The column name reflects the comparison period.
• Current budget status: The partition’s current budget status. Partitions without a budget display --.

Use this table to investigate partitions with growing consumption or dropped data.

​

Next steps

Based on your findings, refine your partitions with more specific dimensions. For example, add child partitions to control smaller subsets of data. After analyzing your consumption and refining partitions, create budgets to apply shaping policies that provide guardrails against usage overages and overspending.
