Handlers are should be an executable or command line string. You can specify multiple reporters and noticers. In this case, they are executed concurrently.

Usage

Normally you can use horenso with a wrapper shell script like following.

#!/bin/bash
/path/to/horenso \
  -n /path/to/noticer.py         \
  -r /path/to/reporter.pl        \
  -r 'ruby /path/to/reporter.rb' \
  -- "$@"

And specify this wrapper.sh in the crontab like following.

3 4 * * * /path/to/wrapper.sh /path/to/job --args...

If you want to change reporting way, you just have to change reporter script. You have no risk to crash wrapper shell.

Execution Sequence

1. Start the command
2. [optional] Run the noticers
3. Wait to finish the command
4. Run the reporters
