Advanced settings have reasonable defaults in place. A warning message displays for some settings advising of the dangers of making changes. Changing advanced settings can be dangerous when done incorrectly. Use caution before saving changes.
Make sure you are comfortable with ZFS, Linux, and system configuration, backup, and restoration before making any changes.
By default, TrueNAS writes system logs to the system boot device. The Syslog widget on the System > Advanced screen allows users determine how and when the system sends log messages to a connected syslog server.
An automatic script sends a nightly email to the administrator account containing important information such as the health of the disks. Configure the system to send these emails to the administrator remote email account for fast awareness and resolution of any critical issues.
Scrub Task issues and S.M.A.R.T. reports are mailed separately to the address configured in those services. Setting Up User Accounts Configure the email address for the admin user as part of your initial system setup or using the procedure below.
SNMP (Simple Network Management Protocol) monitors network-attached devices for conditions that warrant administrative attention. TrueNAS uses Net-SNMP to provide SNMP. To configure SNMP, go to System Settings > Services page, find SNMP, and click the edit.
See SNMP Service Screen for setting information.
Port UDP 161 listens for SNMP requests when starting the SNMP service.
