sudo nano /etc/monit/conf.d/plex
Incollate questo (modificando le porte nel caso vi servissero, ma la 32400 dovrebbe andar bene):
check process Plex with pidfile "/var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/plexmediaserver.pid"
start program = "/usr/sbin/service plexmediaserver start" with timeout 60 seconds
stop program = "/usr/sbin/service plexmediaserver stop"
if failed host 127.0.0.1 port 32400 with timeout 30 seconds for 5 cycles then restart
#if failed port 32401 with timeout 30 seconds for 5 cycles then restart
#if failed port 32469 with timeout 30 seconds for 5 cycles then restart
#if failed port 1909 with timeout 30 seconds for 5 cycles then restart
#if failed url http://127.0.0.1:32400/web/index.html with timeout 30 seconds for 5 cycles then restart
E poi riavviate Monit con:
sudo monit reload
