# PostgreSQL for 1C cluster logs

Logging uses the [Logs](/logs/) service. For more information about how the service works and its cost, see the [Logs Service Overview](/logs/about/about-logs.mdx) guide. You can check the availability of the Logs service across locations in the [Logs Availability by Location](/logs/about/logs-availability-by-location.mdx).

For a PostgreSQL for 1C Managed Database cluster, events in PostgreSQL databases are logged.

To collect cluster logs in the Logs service, [enable logging](#enable-logs). You can [get logs](#get-logs) in the control panel using API requests or via [AWS CLI](/logs/tools/aws-cli.mdx). If you no longer need to collect logs, you can [disable logging](#disable-logs).

Logs are stored for 30 days.

For more information about logging in PostgreSQL databases, see the [Error Reporting and Logging](https://www.postgresql.org/docs/current/runtime-config-logging.html) guide in the PostgreSQL documentation.

## Enable logging \{#enable-logs}

<EnableLogs DatabaseName="PostgreSQL for 1C" ArticleName="Monitoring of the cluster, nodes and databases PostgreSQL for 1C" slug="postgresql-for-1c" />

## Get logs \{#get-logs}

Use the [Get logs](/logs/manage/get-logs.mdx) instructions in the Logs section.

An event stream `postgresql.log-<instance_id>` will be created for the PostgreSQL for 1C Managed Database cluster, where `<instance_id>` is the node ID of the PostgreSQL for 1C cluster.

View the description of [log fields](#fields) for the PostgreSQL cluster.
