Dear list,
I’m trying to monitor an USB port.
The script „checkUSB.sh“ returns „error“ or „exists“ (successfully tested in Terminal as root).
Monit runs as root but with
check program checkUSB with path "/usr/local/sbin/checkUSB.sh"
if content != "exists" then alert
never returns. The process runs forever and is then killed by timeout.
Hello Tino!
Checks run under the same user as Monit.
You could debug it with
logger $(whoami)
in your script or with monit status command.
Hello Viktor,
thank you so much for your reply!
Monit runs as root, and so does the script (like in my tests).
I can see it on my conole:
root 13052 0.0 0.0 1940 384 ? Ss 10:54 0:00 /bin/sh /usr/local/sbin/checkUSB.sh
root 13055 0.0 0.0 1940 68 ? S 10:54 0:00 /bin/sh /usr/local/sbin/checkUSB.sh
Any more ideas?
As I cannot see what is inside the script it is not possible to help.
I’m sorry, it’s not a secret:
#!/bin/sh # test for existence and readability of ttyUSB logger $(whoami)
PORT=`more /etc/gammu-smsdrc |grep tty|cut -d ' ' -f 3|cut -d '/' -f 3`
RESULT=`ls -l /dev/tty*|grep $PORT`
if [ -z "$RESULT" ] then echo "error" else echo "exists" fi
exit 0
And now I recognized that using „more“ instead of „cat“ of course is a bad idea if not running in an interactive terminal. 🙄
Thank you so much for pushing me into the right direction!
Tino
