# Viewing serial logs of virtual machines

Compute virtual machines write logs from a serial console. Serial logs may help you with troubleshooting VM startup and shutdown failures, operating system incidents or other similar issues.

Serial logs are kept for 14 days. The logs for deleted instances are also kept for 14 days, but you cannot see them in the [web console](#view-serial-logs-in-web-console). Use [Grafana®](#view-serial-logs-in-grafana) or [LogCLI](#query-serial-logs-with-logcli) to view logs of deleted instances.

Serial logs for Compute are free of charge.

## View serial logs in Grafana®

You can visualize the serial logs of services in Grafana.

After you [connect Grafana](../../observability/logs/grafana#how-to-connect-grafana), set the `__bucket__` label value to `sp_serial`.

## Query serial logs with LogCLI

After you [set up LogCLI](../../observability/logs/logcli), set the `__bucket__` label value to `sp_serial` in your queries, for example:

```bash theme={null}
logcli query '{__bucket__="sp_serial"}' --since 15m
```
