# View logs

The **Logs** tab of a Load Balancer shows what the Load Balancer has written, so you can look into
a problem from inside the portal. You can narrow the lines, refresh them on a timer, and
download them.

## Before you begin

- A Load Balancer that has finished creating, because a Load Balancer that is still **Initializing**
  shows only its creation progress. See [Create a Load
  Balancer](/tir/tir-load-balancer/how-to/create-a-load-balancer/).
- The read permission on the Load Balancer service. See [TIR Access Control](/tir/tir-iam/).

## Read the logs

1. In the side menu, under **Compute**, select **Load Balancer**, then select the Load Balancer's name.
2. Select the **Logs** tab.

The tab holds a snapshot of the logs, taken at the time given. To load the latest lines, select **Refresh**.

## Narrow and refresh the lines

- To find a word in the lines already loaded, type it in **Filter lines…**. The filter ignores capital letters.
- To load fewer lines, open **Filter By** and choose **Last N Lines** or **Last N Seconds**, then enter
  a whole number of at least 1 in **Value of N**.
- To reload on a timer, open **Auto Refresh** and choose **5 Seconds**, **10 Seconds**, **30 Seconds**,
  or **1 Minute**.

## Download the logs

Select **Download logs**. TIR loads the logs again with your current **Filter By**
choice and saves them as a JSON file named after the Load Balancer, ending in `-logs.json`.

If the tab says "No logs yet", the Load Balancer has yet to run and handle traffic; logs appear
once it has.

To see traffic as charts instead, read [Monitor a Load
Balancer](/tir/tir-load-balancer/how-to/monitor-a-load-balancer/). For help with a message, see
[Troubleshooting TIR Load Balancer](/tir/tir-load-balancer/troubleshooting/tir-load-balancer/).
