randall526 Posted December 17, 2014 Share Posted December 17, 2014 I looked all over for a script that does this and couldn't find it. If this is a double post, my apologies as I can't imagine I'm the first one to raise this topic. I wanted to share my script that checks if Plex is taking connections on it's default port and attempts to cycle it if not. You would have to place it in the root of your flash drive otherwise known as /boot. This would be run as an hourly cron job or w/e you prefer. To have this change persist across reboots, you must add this to your go file. crontab -l > /tmp/cron; echo '#Run Hourly Plex Connection Check' >> /tmp/cron; echo '30 * * * * /boot/PlexCheck' >>/tmp/cron; crontab /tmp/cron; rm /tmp/cron The script echo's the results to the console which I prefer however you could get rid of it by adding &>/dev/null to the end of the cron job. The script could also be easily edited to have the echo's append to a file as a log that can be checked. I prefer the console. So far my go file and script have been tested and working as expected. In my experience, plex may indeed be running, however it will stop taking connections from time to time. This method will catch both conditions where plex is not running or plex is running but not responding to connections properly and attempt to resolve it. Script attached. You will need to drop the .txt extension when it is placed on your flash drive. PlexCheck.txt Quote Link to comment
randall526 Posted December 17, 2014 Author Share Posted December 17, 2014 Also here's a version that outputs to a log file you can check to make sure it's running and what the results of the run are. The log is /var/PlexCheckLog This is the volital file system that exists in memory and should clear each reboot. I doubt anyone's uptime would be long enough for the log size to ever be a problem so i decided not to add any log rotation or clean up apart of the script. I didn't make seance to put the log on the flash or cache disk. You would be able to view the log when logged into the sever as shown below. root@Tower:/var# cat ./PlexCheckLog Wed Dec 17 13:52:09 CST 2014 Plex appears to be accepting connections! Wed Dec 17 14:30:01 CST 2014 Plex appears to be accepting connections! Wed Dec 17 15:30:01 CST 2014 Plex appears to be accepting connections! root@Tower:/var# tail -10 ./PlexCheckLog Wed Dec 17 13:52:09 CST 2014 Plex appears to be accepting connections! Wed Dec 17 14:30:01 CST 2014 Plex appears to be accepting connections! Wed Dec 17 15:30:01 CST 2014 Plex appears to be accepting connections! PlexCheckv2.txt Quote Link to comment
switchman Posted December 18, 2014 Share Posted December 18, 2014 I would put a loop in it so that it would try say three times, waiting 60 seconds between tries, before it stops/starts plex. This way just in case it is busy and misses the first attempt or even the second. Quote Link to comment
randall526 Posted December 18, 2014 Author Share Posted December 18, 2014 Yeah I could try that. It's humanly possible Plex is doing some heavy streaming or the system is loaded and fail an attempt here and there. That's certainly true with some of my server up SSH port checks to find downed systems at work that use almost the same logic. I'll update it later. Quote Link to comment
randall526 Posted December 18, 2014 Author Share Posted December 18, 2014 Here is my script that adds on 3 retry attempts before restarting plex. I've tested it and it appears to be working. I tried to load the box to test my loaded system condition but that's something a little hard to simulate. Far as I can tell, it should work should that condition arise. Additional logging was sent to /var/PlexCheckLog. You will either have to rename the script to match the entry in the go file or edit the go file to reflect the script name "PlexCheckv3". Logging will now look something like this., That first line is another cron job that cycles Plex at Night anyway. This is a highly paranoid check, not really necessary.

savestheday Posted December 29, 2014 Share Posted December 29, 2014 Have you been having problems with Plex disappearing? I too have had an issue since upgrading to v6. Quote Link to comment
randall526 Posted January 2, 2015 Author Share Posted January 2, 2015 As far as Unraid beta version? I am still running 5.05 myself. v6 was unstable for me last time I tested which was sometime ago. Quote Link to comment
randall526 Posted February 20, 2016 Author Share Posted February 20, 2016 Btw if anyone knows how to bounce a docker as easily as a plex service, I can update this to support version 6 however the issue I created this script for has never surfaced in the mature versions of Unraidv6 yet.
