# Driver logs

> Read what your drivers are saying, across every robot in the environment, from the Logs tab.

The **Logs** tab in the environment workbench shows the log lines your edge
drivers emit, for every robot in the environment at once. It is where you look
when a driver started but nothing moved, or a camera stream never appeared.

## Reading the tail

Lines arrive **newest first**, so the most recent one stays at the top of the
list instead of scrolling away as new lines land. Use the sort button in the
toolbar to flip to oldest-first if you would rather read a startup sequence in
order.

Each line carries a coloured left edge for its severity — red for errors, amber
for warnings, green for info, grey for debug — so you can pick the errors out of
a busy list without reading every message. The level is also named beside the
robot, so it is there when the colour is not enough and it is matched by
**Search**.

## Choosing a time range

The **Range** control sets what the tab reads:

* **Last 5 min** (the default) — a live tail of what is happening now.
* **Last hour** / **Last 24 hours** — for something you have already missed.
* **Custom…** — a fixed start and end. A fixed range is not a tail, so the tab
  loads it once and stops refreshing.

A shorter range is faster to load. Start narrow and widen only when you need to
look further back.

## Knowing when there is more

The counter above the list reads, for example, `40 of 200+ loaded` — how many
lines are on screen after your search and level filters, and how many have been
loaded from the range. A trailing `+` means the range holds more lines than are
loaded. When that happens, **Load older** at the bottom of the list fetches the
next page.

## Narrowing it down

* **Twin** — read one robot instead of the whole environment.
* **Level** — show only the severities you care about.
* **Search** — match on message text, robot name, or anything in the line's
  details.
* **Download** — save every loaded line as JSON, filters included or not.

Click the info icon on any line for its full payload: container name, driver
image, edge-core and SDK versions, and the raw metadata the driver sent.
