JobScheduler Agent jobscheduler_agent_watchdog.sh should print the message when calling script kill_tasks_after_crash.sh only in debug mode

Current situation

• If Agent is terminated abnormally, the jobscheduler_agent_watchdog.sh watchdog process will execute the ../var_4445/tmp/kill_tasks_after_crash.sh script.
• The kill_tasks_after_crash.sh script is created by Agent when the agent starts a first task. The agent will add an entry to this file for each subsequent task started and remove entries as the tasks are completed.
• If the Agent is not executing any tasks the kill_tasks_after_crash.sh script will either not exist or be empty and if the Agent crashes when tasks are not running the Watchdog will print the message:

  • 2018-03-29 18:18:49,290 +0200 [info]  "/opt/sos-berlin.com/jobscheduler_agent/var_4445/tmp/kill_tasks_after_crash.sh" doesn't exist or is empty. Nothing to do."

• This message is confusing and doesn't say that tasks were not running.

Desired Behavior

• The message should only be shown in debug mode.
• The Message should be modified to read, for example:

  • "/opt/sos-berlin.com/jobscheduler_agent/var_4445/tmp/kill_tasks_after_crash.sh" doesn't exist or is empty. No tasks were running. Nothing to do."
