[http://mmonit.com/monit Monit] (Amahi's watchdog) is a utility for managing and monitoring processes, programs, files, directories and filesystems on a Unix system. It is integrated in Amahi and managed using the '''''Servers''''' section of the '''Settings''' tab.  Monit has an integrated web interface which can exposed using the [http://www.amahi.org/apps/monit -service-manager MonitService Manager] web access is one-click app. This app provides additional detail about the processes currently in ALPHA status for running on your HDA. Monit configuration file locations: * Main (monitrc):** Ubuntu - /etc/monit** Fedora - /etc * Services:** Ubuntu - /etc/monit/monit.d** Fedora 14 - /etc/monit.d  == Change Hostname ==Edit monitrc and Ubuntu 12change ''localhost.04localdomain'' to match your system: check system localhost.localdomain

This will only work if you have set up your HDA to send emails. The [[Gmail_As_Relay_On_Ubuntu|Gmail as Relay]] tutorial is one option.  You can do it in Monit directly by adding the following to monitrc: set mailserver smtp.gmail.com port 587 username "MYUSER" password "MYPASSWORD" using tlsv1  '''NOTE:''' Replace "MYUSER" and "MYPASSWORD" with your Gmail user name and password. Enable email notifications by editing monitrc and adding the following lines (Change as needed to match your system):set mailserver localhostset mail-format { from: monit@localhost }set alert root@localhost  Restart Monit:* Ubuntu sudo /etc/init.d/monit restart* Fedora (root user) systemctl restart monit.service == Change Message Format ==Edit monitrc and add this text (modify as needed): set mail-format { from: monit@localhost subject: [ $SERVICE ] $EVENT - $DATE message: This is an $ACTION: $DESCRIPTION [$SERVICE], tested remotely from $HOST }  Restart Monit:* Ubuntu sudo /etc/init.d/monitrestart* Fedora (root user) systemctl restart monit.service == Change Access Credentials ==Edit monitrc and change as desired: allow admin:admin  Restart Monit:* Ubuntu sudo /etc/init.d/monit restart* Fedora (root user) systemctl restart monit.service == Enable Secure access (Fedora) ==Edit monitrc and uncomment add below <u>set httpd port 2812 and</u> (line 116): SSL ENABLE PEMFILE /var/certs/monit.pem  Create a directory for the certs, then follow "Create New Certificate" guidance: mkdir -p /var/certs == Create New Certificate ==A default certificate is installed by the Amahi application (Ubuntu).
