# Agent 5 Log Files

## Overview{% #overview %}

This page covers Agent 5 log files. Datadog recommends installing or upgrading to Agent 7 for the latest features. For information on installing the latest version of the Agent, follow the [Agent 7 Installation Instructions](https://app.datadoghq.com/account/settings/agent/latest?platform=overview). For information on upgrading to Agent 7 from an earlier version, see [Upgrade to Datadog Agent v7](https://docs.datadoghq.com/agent/versions/upgrade_to_agent_v7/).

The Datadog Agent does a logs rollover every 10MB by default. When a rollover occurs, one backup (`agent.log.1`) is kept. If a previous backup exists, it is overwritten during the rollover. To set the maximum size of one log file and the maximum number of backup files to keep, use `log_file_max_size`(default: 10485760 bytes) and `log_file_max_rolls`(default: 1) in the [Agent configuration file](https://docs.datadoghq.com/agent/guide/agent-5-configuration-files#agent-main-configuration-file).
