# Quickfix, because Logentries tries to use python2 instead of python (python2 is not available on OS X - python is actually python 2)
#
print_and_do_command_exit_on_error sudo ln -s /usr/bin/python /usr/bin/python2


# this is the official Logentries install command
curl -O https://raw.githubusercontent.com/logentries/le/master/install/mac/install.sh && sudo sh install.sh
if [ $? -ne 0 ]; then
  echo " [!] Failed to install Logentries agent"
fi

# for test just unload and re-load -> this should start to send data from the system log
print_and_do_command_exit_on_error sudo launchctl unload /Library/LaunchDaemons/com.logentries.agent.plist
print_and_do_command_exit_on_error sudo launchctl load /Library/LaunchDaemons/com.logentries.agent.plist

#
# you can register your additional log files with:
#  $ sudo le follow path/to/the/file
# sudo is important, by the default logentries agent is started with sudo
#  and if you try to add new log files without sudo it'll handle it as a separate, 
#  non-sudo logentries agent (meaning: will start a new agent and you have to start it as well as the sudo one)
#

# after the 'follow' of new log files you have to call:
#  sudo launchctl unload /Library/LaunchDaemons/com.logentries.agent.plist && sudo launchctl load /Library/LaunchDaemons/com.logentries.agent.plist
# to start the monitoring

# you can add a quick test entry to the syslog with:
logger "logentries quick test"
