## Overview

The **Logs** page streams RouterOS events into a filterable table. Three
controls sit above it, namely a multi-select for severity **Level**, a multi-select
for **Topic** built from the topics actually present in the stream, and a free
text **Search** that matches anywhere in the message. Badges below the filters
count how many entries fall into each severity.

Clicking a row opens **Log details**, which shows the full entry field by
field. Use it when a message is truncated in the table.

The page is not on the router tab bar. Reach it at
`/router/<router-id>/logs` in the panel.

## Before you start

- The session must hold valid credentials for this router.
- RouterOS only keeps a limited buffer of log entries; the panel shows what the
  router still holds.

## Steps

1. Open the logs page for the router.
2. Narrow by severity with the **Level** select, which is searchable and accepts
   several values at once. Leave it empty for **All levels**.
3. Narrow by subsystem with the **Topic** select. Leave it empty for **All
   topics**.
4. Type a keyword into **Search**. The filter is debounced, so it applies a
   moment after you stop typing.
5. Click a row to open **Log details**, and page through results with the
   previous and next buttons.
6. Press **Refresh** to pull the stream again.

## Reference

### Levels

`info`, `warning`, `error`, `critical`, `debug`.

### Log details fields

| Field | What it shows |
| ----- | ------------- |
| Timestamp | When RouterOS recorded the entry. |
| Level | Its severity. |
| Topic | The RouterOS topics attached to it. |
| Message | The full message text. |
| Log ID | The entry's identifier. |
| Prefix | The log prefix, where one is set. |
| Account | The account associated with the entry, where there is one. |
| Count | How many times the entry repeated. |

## Troubleshooting

**The stream is empty after filtering.** Clear the **Level** and **Topic**
selects and the **Search** box, then narrow again one control at a time.

**Nothing loads at all.** Press **Refresh**, and check the router is reachable
and the session credentials are valid.
