# Filter

> Filter logs by category and time

Filters help you narrow down your logs to find exactly what you're looking for. Combine multiple filters to create precise views of your system's behavior.

### Quick Access

Press `F` from anywhere to filter on categories and `⌥ 1-6` to shuffle through time range.

### Categories

<AccordionGroup>
  <Accordion icon="square-asterisk" title="Log Level">
    Filter by log severity to focus on specific types of messages. Use `ERROR` and `CRITICAL` when investigating incidents, or include `INFO` and `DEBUG` during development and troubleshooting.
  </Accordion>

  <Accordion icon="zap" title="Operation">
    Filter by specific operations or tasks within your system. Operations represent granular actions like `daily-pdf-export`, `user-authentication`, or `data-sync` that help you track individual processes.
  </Accordion>

  <Accordion icon="component" title="Component">
    Filter by logical components that group related operations together. Components represent functional units like `daily-export`, `notification-service`, or `payment-processor` that organize your system's architecture.
  </Accordion>

  <Accordion icon="box" title="Service">
    Filter by the service or application that generated the logs. Services represent deployment units like `api-server`, `worker-queue`, `database`, or `scheduler` that make up your infrastructure.
  </Accordion>

  <Accordion icon="globe" title="Domain">
    Filter by business or technical domain to organize logs by area of responsibility. Domains represent high-level categories like `data-infrastructure`, `user-management`, or `billing` that help structure your organization's systems.
  </Accordion>
</AccordionGroup>

### Time range

<AccordionGroup>
  <Accordion icon="clock-fading" title="Without active filters">
    Filter logs by time period. Use keyboard shortcuts `⌥ 1-6` for quick access or change through tabs:

    * `⌥ 1` - 30 minutes (default)
    * `⌥ 2` - 1 hour
    * `⌥ 3` - 4 hours
    * `⌥ 4` - 8 hours
    * `⌥ 5` - 1 day
    * `⌥ 6` - 7 days
  </Accordion>

  <Accordion icon="clock-9" title="With active filters">
    When filters are applied, the above still works. However, you cal also press `T` to open the time filter menu.
  </Accordion>
</AccordionGroup>

## Quick Tip

Once you've created a useful filter combination, save it as a [View](/essentials/view) so you can access it instantly next time.
