Monit

if installed with apt systemd file is already in.

sudo nano /etc/monit/monitrc

changed:

set alert ractive74@gmail.com

set mailserver smtp.gmail.com port 587 
   username "MYUSER" password "MYPASSWORD"
   using tlsv12

  check system $HOST
    if loadavg (1min) > 4 then alert
    if loadavg (5min) > 2 then alert
    if cpu usage > 95% for 10 cycles then alert
    if memory usage > 75% then alert
    if swap usage > 25% then alert

 check network public with interface eth0
   if failed link then alert

sudo systemctl restart monit

sudo monit -t

sudo monit start all

sudo monit status

monit not starting up correctly on reboot...so I deleted the init.d/monit script and made a monit.service file

1. This file is systemd template for monit service. To
2. register monit with systemd, place the monit.service file
3. to the /lib/systemd/system/ directory and then start it
4. using systemctl (see bellow).
6. Enable monit to start on boot:
7. systemctl enable monit.service
9. Start monit immediately:
10. systemctl start monit.service
12. Stop monit:
13. systemctl stop monit.service
15. Status:
16. systemctl status monit.service
