I am using the whenever gem to configure my crontab and schedule cron jobs. my config/schedule.rb file has the following content:
set :environment, "test"
set :output, {:error => "/var/log/cron_error.log", :standard => "/var/log/cron_log.log"}
every 1.minutes do
runner 'TickerSymbol.update_prices'
end
At the moment I am invoking Rails.logger.debug ... in the TickerSymbol.update_prices method. Also, notice in the schedule.rb file that I am trying to write the output from the scheduled cron job to /var/logs/*.log. This is not working. When I view the logs on S3 or via the Beanstalk management console I see other log files from the /var/log directory, but I do not see my cron log files.
My .ebextensions/[app name].config file has the following content:
sources:
/aws-scripts-mon: http://ec2-downloads.s3.amazonaws.com/cloudwatch-samples/CloudWatchMonitoringScripts.zip
option_settings:
- option_name: AWS_SECRET_KEY
value: XXX

Following is the content from my log file which is generated during my deployment with git aws.push. This log entry confirms that whenever is generating the crontab file as expected.

Am I missing something? Based on the current configuration, I expect to see my log messages from TickerSymbol.update_prices inside my /var/log/cron_log.log file. However, I dont see any indication that these settings are producing an error nor do I see any indication that the cron job is running.
