Check if Plex is running, restart if not?

[OneCD]

For some reason it works from the # shell prompt and not from crontab. Any suggestions?

Can you please post your crontab entry here?

Yep, here it is - set to run every 10 mins rather than 5:

Code: Select all

*/10 * * * * /sbin/curl --silent --insecure --fail --max-time 10 http://127.0.0.1:32400; [[ $? -ne 22 ]] && /etc/init.d/plex.sh restart >/dev/null 2>&1

This command runs as expected in a terminal window, but restarts plex every 10 mins with cron...

Can you please confirm the exit code after running curl on an operational Plex instance?

Code: Select all

/sbin/curl --silent --insecure --fail --max-time 10 http://127.0.0.1:32400; echo $?

Yep, sure - I just ran it (wihout "--silent") and got an error code [7] as PMS isnt running properly (confirmed with plexamp app etc):

Code: Select all

curl: (7) Failed to connect to 127.0.0.1 port 32400: Connection refused
7

Running the following succesfully restarted PMS:

Code: Select all

/sbin/curl --silent --insecure --fail --max-time 10 http://127.0.0.1:32400; [[ $? -ne 22 ]] && /etc/init.d/plex.sh restart >/dev/null

Now PMS is running, I get the [22] code returned:

Code: Select all

# /sbin/curl --silent  --insecure --fail --max-time 10 http://127.0.0.1:32400; echo $?
22

Do you get the same return code when using the —silent parameter?

Maybe you’ll need to increase the check frequency, like the OP of this topic did?

Yes, the return codes are working at the terminal, checked with "echo $?", but assume that cron is seeing something different. I was wondering if cron is blocked from using curl or its environment generates a different code. After PMS died yesterday and I saw that return code [7] was given, I have changed the logic in the crontab to read

Code: Select all

[[ $? = 7 ]]

Hope that cron gets this - been running via cron every 10 minutes overnight and it doesnt restart PMS unecessarily. I'll check the QTS notification centre for Plex restart messages, once I see them then I know it works.

If I did that with the [[ $? -ne 22 ]] then it would be restarting every 5 minutes!

you could write the return code to a file and check this while it's running via cron, just to see if execution via cron returns something unexpected

odd. the file says 22!
I've left my crontab entry looking for a code [7] and lets see if that picks up PMS breaking. It was happening nearly daily, so hopefully I will find out soon.
