View the Server Log and Restart Server

About Server Logs

We use supervisor to run and manage the logs for the eVOLVER server. eVOLVERs should come pre-configured with this.

We also provide a utility monitoring and restart script, evolvercron and server_monitor.sh. To use, add the crontab job line in evolvercron into your cron installation.
