Re: Monit: 'Matching' functionality isn't working

[Marie Mcallister]

Hi Martin,

Yes, that is what I tried as well, noted before.

"> I tried formatting it as such: start program = "/bin/bash -c 'nohup /mnt1/build/seeing/build/bin/run.sh &'" but the same thing occurs."

It won't run this for some reason - when I check logs, it says:

[UTC Jun 24 21:25:05] error    : 'classification_node' process is not running

[UTC Jun 24 21:25:05] info     : 'classification_node' trying to restart

[UTC Jun 24 21:25:05] info     : 'classification_node' start: /bin/bash

[UTC Jun 24 21:25:35] error    : 'classification_node' failed to start

(Why does it stop at the whitespace after bash? This seems to be the issue.)

The pattern in the process check and the start program are two different things - the start program is not regular _expression_, but regular program to execute. Please remove the “^” character from the start program:

        start program = “/bin/bash -c 'nohup /mnt1/build/seeing/build/bin/run.sh &'"
