**Usage** shows how your workspace consumes messages and knowledge resources.
## What you will learn
* Which usage metrics are available
* How to filter usage by Agent and date
* How to use usage charts for planning
## Open Usage
Open **Usage** from the sidebar.
## Review usage cards
The overview cards summarize workspace-level usage. Use them to understand current consumption before reviewing the charts.
## Filter by Agent and date
Use the header filters to select all Agents or one Agent. Choose a date range to compare short-term and month-to-date activity.
## Messages over time
Use **Daily Messages** to understand traffic patterns. Spikes can indicate campaigns, support incidents, or successful deployments.
## Usage by Agent
Use **Messages by Agent** and **Knowledge by Agent** to understand which Agents are active and which ones have the most source content.
