Re: Start command IO redirection not working

[Martin Pala]

Hi,

monit execute the script directly, it doesn’t run it using shell - if you need 
I/O redirection, backticks, pipes, etc., you need to wrap it the same way the 
stop command is wrapped:

       start program = “/bin/bash -c ‘/home/ubuntu/xyz.py &> 
/home/ubuntu/logs/xyz_`date +\%m_\%d_\%y_\%H_\%M_\%S`.log'”

Regards,
Martin
