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.
