# Browse NAPs

**Browse NAPs** is a NAP report builder. By default it shows one row per NAP per device with live data. Switch to historical mode for aggregated analysis over any time window.

Open from **TB Nodes > Browse NAPs**.

## Controls

| Control                  | What it does                                                                                                                |
| ------------------------ | --------------------------------------------------------------------------------------------------------------------------- |
| **Combine NAPs**         | Merge NAPs with the same name across devices into a single row showing aggregated totals.                                   |
| **Switch to Historical** | Swap live polling for historical aggregation. Select a range from 1 hour to 90 days, or custom dates.                       |
| **Columns**              | Pick which of the 27 NAP metrics to display. In historical mode, each column shows its aggregation (Total, Avg, Peak, Min). |
| **Exclude Hosts**        | Hide specific devices from the table — useful for excluding lab equipment.                                                  |
| **Views**                | Save the current column selection, filters, and settings as a named view. Load it back later with one click.                |
| **Export**               | Download the current table as CSV or JSON.                                                                                  |

## Historical Mode

When you switch to historical, column aggregation is applied automatically based on metric type:

| Metric Type                   | Default Aggregation | Why                                                                                            |
| ----------------------------- | ------------------- | ---------------------------------------------------------------------------------------------- |
| Counters (call counts, drops) | **Total**           | True sum over the period.                                                                      |
| Rates (CPS)                   | **Average**         | Rates don't sum meaningfully.                                                                  |
| Quality (MOS)                 | **Average**         | Quality over time.                                                                             |
| Call Legs                     | **Average**         | Call legs are concurrent, not a running count — summing would double-count. Avg/Peak/Min only. |

You can change the aggregation per column in the column selector.

## Saved Views

Views are stored in your browser. They capture: active columns, per-column aggregation, combine toggle, excluded hosts, live/historical mode, and time range.

To move views between browsers, use **Export Views** and **Import Views** in the Views menu.

***

## Refresh Behavior

* Live mode auto-refreshes.
* Historical mode is static — the data for the selected range doesn't change, so there's no auto-refresh. Change the range or mode to re-query.

## Drill-Through

Click any NAP name to open its NAP Detail page, showing all 27 metrics for that NAP on that device with a configurable chart.
